Background: Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in childhood. Survival for patients following relapse remains poor, and achieving complete remission (CR) after relapse is the first critical step to cure. Carfilzomib is a proteasome inhibitor with an acceptable safety profile and clinical activity in adults with multiple myeloma but has not been assessed in children. The primary objective of this phase 1b study was to assess the safety and tolerability of carfilzomib combined with vincristine, dexamethasone, asparaginase, and daunorubicin (VXLD) in children with relapsed and/or refractory ALL., Methods: Patients aged 1-21 years (n = 24) received 4-week induction therapy with carfilzomib at dose levels of 27 mg/m 2 (n = 3), 36 mg/m 2 (n = 7), 45 mg/m 2 (n = 4), and 56 mg/m 2 (n = 10) in combination with VXLD. Patients achieving stable disease were offered further consolidation chemotherapy. Analyses were based on the safety evaluable population., Results: Following dose escalation of carfilzomib, the recommended phase 2 carfilzomib dose was identified as 56 mg/m 2 . Grade ≥3 hematological adverse events were common (83%, 20/24 patients), and serious treatment-emergent adverse events occurred in 58% (14/24) of patients. At the end of induction, CR/CR with incomplete platelet recovery (CRp)/CR with incomplete blood count recovery (CRi) was identified in 50% of patients (n = 12/24). By the end of consolidation, cumulative CR/CRp/CRi was identified in 58% of patients (n = 14/24)., Conclusion: These data support the use of carfilzomib in pediatric patients with relapsed and/or refractory ALL., (© 2022 The Authors.

Recent approval of several novel agents has dramatically improved outcomes for patients with relapsed and refractory (R/R) B-cell acute lymphoblastic leukemia. Blinatumomab, a bi-specific T-cell engager targeted to CD3 and CD19, inotuzumab ozogamicin (InO), an antibody-drug conjugate to CD22, and tisagenlecleucel, a CD19 chimeric antigen receptor T-cell with a 4-1BB costimulatory domain, have all demonstrated impressive response rates in R/R B-ALL as compared to historic controls. However, important considerations when choosing among these novel agents include clinical features that may impact efficacy, such as relative disease burden, antigen expression, and T-cell function, as well as patient and disease characteristics that may contribute to risk of toxicity. In addition, suitability of the patient for hematopoietic stem cell transplant (HSCT) as well as patient preference must also be considered. This review will focus on factors to weigh when choosing an agent in the setting of R/R disease and important challenges moving forward., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: A partial response according to the Response Evaluation Criteria in Solid Tumors includes a wide range of changes in tumor size. This study evaluated whether further specification of tumor reduction based on the depth of response (DpR) would provide a more precise association with outcomes for patients with non-small cell lung cancer (NSCLC) treated with first-line platinum-based chemotherapy., Methods: A retrospective analysis was performed for the randomized phase 3 CA031 trial in patients with NSCLC treated with carboplatin in combination with nab-paclitaxel or solvent-based paclitaxel. Quartiles according to the maximum tumor reduction from the baseline were defined (quartile 1 [Q1], >0% to 25%; quartile 2 [Q2], >25% to 50%; quartile 3 [Q3], >50% to 75%; and quartile 4 [Q4], >75%) and were compared with those patients with no tumor reduction (NTR). The primary objective was to evaluate the association between DpR and overall survival (OS)., Results: Of the 1052 patients enrolled in the CA031 trial, 959 (91%) were evaluable, and they included 365 (38.1%) who were classified as Q1, 327 (34.1%) who were classified as Q2, 131 (13.7%) who were classified as Q3, and 34 (3.5%) who were classified as Q4; 102 had NTR (10.6%). The median OS values for patients in the NTR, Q1, Q2, Q3, and Q4 groups were 4.8, 10.4, 14.5, 19.3, and 23.5 months, respectively. The maximum DpR on treatment was an independent predictor of improved OS in comparison with patients with NTR; the hazard ratio decreased from 0.43 in Q1 to 0.16 in Q4., Conclusions: DpR was strongly associated with OS in patients with NSCLC receiving first-line platinum-based therapy. Additional studies may help to define the role of DpR in solid tumors., (© 2019 American Cancer Society.)

Purpose: In the randomized, open-label, phase III KEYNOTE-024 study, pembrolizumab significantly improved progression-free survival and overall survival (OS) compared with platinum-based chemotherapy in patients with previously untreated advanced non-small-cell lung cancer (NSCLC) with a programmed death ligand 1 tumor proportion score of 50% or greater and without EGFR/ALK aberrations. We report an updated OS and tolerability analysis, including analyses adjusting for potential bias introduced by crossover from chemotherapy to pembrolizumab., Patients and Methods: Patients were randomly assigned to pembrolizumab 200 mg every 3 weeks (for up to 2 years) or investigator's choice of platinum-based chemotherapy (four to six cycles). Patients assigned to chemotherapy could cross over to pembrolizumab upon meeting eligibility criteria. The primary end point was progression-free survival; OS was an important key secondary end point. Crossover adjustment analysis was done using the following three methods: simplified two-stage method, rank-preserving structural failure time, and inverse probability of censoring weighting., Results: Three hundred five patients were randomly assigned (pembrolizumab, n = 154; chemotherapy, n = 151). At data cutoff (July 10, 2017; median follow-up, 25.2 months), 73 patients in the pembrolizumab arm and 96 in the chemotherapy arm had died. Median OS was 30.0 months (95% CI, 18.3 months to not reached) with pembrolizumab and 14.2 months (95% CI, 9.8 to 19.0 months) with chemotherapy (hazard ratio, 0.63; 95% CI, 0.47 to 0.86). Eighty-two patients assigned to chemotherapy crossed over on study to receive pembrolizumab. When adjusted for crossover using the two-stage method, the hazard ratio for OS for pembrolizumab versus chemotherapy was 0.49 (95% CI, 0.34 to 0.69); results using rank-preserving structural failure time and inverse probability of censoring weighting were similar. Treatment-related grade 3 to 5 adverse events were less frequent with pembrolizumab compared with chemotherapy (31.2% v 53.3%, respectively)., Conclusion: With prolonged follow-up, first-line pembrolizumab monotherapy continues to demonstrate an OS benefit over chemotherapy in patients with previously untreated, advanced NSCLC without EGFR/ALK aberrations, despite crossover from the control arm to pembrolizumab as subsequent therapy.

Background: Malignant pleural mesothelioma is an aggressive cancer with highly vascularised tumours. It has poor prognosis and few treatment options after failure of first-line chemotherapy. NGR-hTNF is a vascular-targeting drug that increases penetration of intratumoral chemotherapy and T-cell infiltration by modifying the tumour microenvironment. In this trial, we aimed to investigate the efficacy and safety of NGR-hTNF in patients with malignant pleural mesothelioma who had progressed during or after a first-line treatment., Methods: NGR015 was a randomised, double-blind, placebo-controlled phase 3 trial done in 41 centres in 12 countries. Eligible participants had malignant pleural mesothelioma of any histological subtype (epithelial, sarcomatoid, or mixed), were aged 18 years or older, and had an Eastern Cooperative Oncology Group performance status of 0-2 and radiologically documented progressive disease after one pemetrexed-based chemotherapy regimen. Participants were randomly assigned to receive weekly NGR-hTNF 0·8 μg/m 2 intravenously plus best investigator choice (n=200), or placebo plus best investigator choice (n=200). Best investigator choice was decided before random assignment and could be single-agent gemcitabine (1000-1250 mg/m 2 intravenously), vinorelbine (25 mg/m 2 intravenously or 60 mg/m 2 orally), doxorubicin (60-75 mg/m 2 intravenously), or best supportive care only. Patients were randomised (1:1) with a block size of four after stratification for performance status and best investigator choice. The primary study endpoint was overall survival in the intention-to-treat population. The trial is closed to new participants and is registered with ClinicalTrials.gov (NCT01098266)., Findings: Between April 12, 2010 and Jan 21, 2013, we enrolled 400 eligible participants. 381 (95%) of 400 patients were selected to receive chemotherapy before all participants were randomly assigned to receive NGF-hTNF plus best investigator choice (n=200) or placebo plus best investigator choice (n=200). At the cutoff date (April 29, 2014), the median follow-up was 18·7 months (IQR 15·1-24·4), and overall survival did not differ between the two treatment groups (median 8·5 months [95% CI 7·2-9·9] in the NGR-hTNF group vs 8·0 months [6·6-8·9] in the placebo group; hazard ratio 0·94, 95% CI 0·75-1·18; p=0·58). Grade 3 or worse study-emergent adverse events occurred in 136 (70%) of patients receiving NGR-hTNF versus 118 (61%) of patients receiving placebo, with the most common being neutropenia (35 [18%] of 193 patients vs 36 [19%] of 193 patients), pain (11 [6%] vs 16 [8%]), dyspnoea (nine [5%] vs seven [4%]), and chills (nine [5%] vs none). 50 (26%) patients in the NGR-hTNF group had a serious adverse event, compared with 47 (24%) in the placebo group. Treatment-related serious adverse events occurred in 17 (9%) patients in the NGR-hTNF group and 20 patients (10%) in the placebo group. There were 12 deaths in the NGR-hTNF group and 13 deaths in the placebo group, but none were treatment related., Interpretation: The study did not meet its primary endpoint. The hypothesis-generating findings from the subgroup analyses deserve a confirmatory randomised trial because patients who rapidly progress after first-line treatment have a poor prognosis., Funding: MolMed., (Copyright © 2018 Elsevier Ltd.

Purpose: Leptomeningeal disease (LMD) is an uncommon complication of advanced breast cancer. The prognosis is poor, and although radiotherapy (RT), systemic and intra-thecal (IT) chemotherapy are accepted treatment modalities, efficacy data are limited. This study was designed to evaluate potential predictors of survival in this patient group., Methods: Breast cancer patients with LMD diagnosed by MRI in a 10-year period (2004-2014) were identified from electronic patient records. PFS and OS estimates were calculated using Kaplan-Meier method, with planned sub-group analysis by treatment modality. Cox regression was employed to identify significant prognostic variables., Results: We identified 182 eligible patients; all female, median age at LMD diagnosis 52.5 years (range 23-80). Ninety patients (49.5%) were ER positive/HER2 negative; 48 (26.4%) were HER2 positive, and 27 (14.8%) were triple negative. HER2 status was unknown in 17 (9.3%). Initial management of LMD was most commonly whole or partial brain RT in 62 (34.1%), systemic therapy in 45 (24.7%) or supportive care alone in 37 (20.3%). Fourteen patients (7.7%) underwent IT chemotherapy, of whom two also received IT trastuzumab. From diagnosis of LMD, the median PFS was 3.9 months (95%CI 3.2-5.0) and median OS was 5.4 months (95%CI 4.2-6.6). Patients treated with systemic therapy had the longest OS (median 8.8 months, 95%CI 5.5-11.1), compared to RT; 6.1 months (95%CI 4.2-7.9 months), IT therapy; 2.9 months (95%CI 1.2-5.8) and supportive care; 1.7 months (95%CI 0.9-3.0). On multivariable analysis, triple negative histology, concomitant brain metastases, and LMD involving both the brain and spinal cord were associated with poor OS., Conclusions: Breast cancer patients with triple negative LMD, concomitant brain metastases or LMD affecting both the spine and brain have the poorest prognosis. Clinical trials to identify more effective treatments for these patients are urgently needed., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: In the phase 3 KEYNOTE-024 trial, treatment with pembrolizumab conferred longer progression-free survival than did platinum-based therapy in patients with treatment-naive, advanced non-small-cell lung cancer (NSCLC) with a programmed cell death-ligand 1 (PD-L1) tumour proportion score of 50% or greater (PD-L1-positive). Here we report the prespecified exploratory endpoint of pembrolizumab versus chemotherapy on patient-reported outcomes (PROs)., Methods: In this multicentre, international, randomised, open-label, phase 3 trial, we recruited patients with treatment-naive, stage IV NSCLC in 102 sites in 16 countries. Eligible patients had measurable disease (per RECIST version 1.1) and an Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. Patients were randomly assigned (1:1) via an interactive voice response system and integrated web response system to receive either pembrolizumab 200 mg every 3 weeks (35 cycles) or investigator-choice platinum-doublet chemotherapy (4-6 cycles or until documented disease progression or unacceptable toxicity). Randomisation was stratified according to geography, ECOG performance status, and histology. PROs were assessed at day 1 of cycles 1-3, every 9 weeks thereafter, at the treatment discontinuation visit, and at the 30-day safety assessment visit using the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 items (QLQ-C30), the EORTC Quality of Life Questionnaire Lung Cancer 13 items (QLQ-LC13), and the European Quality of Life 5 Dimensions-3 Level (EQ-5D-3L) questionnaire. The key exploratory PRO endpoints (analysed for all patients who received at least one dose of study treatment and completed at least one PRO instrument at at least one timepoint) were baseline-to-week-15 change in the QLQ-C30 global health status (GHS)/quality-of-life (QOL) score and time to deterioration of the composite of cough, chest pain, and dyspnoea in the QLQ-LC13. This study is registered with ClinicalTrials.gov, number NCT02142738, and is ongoing but no longer enrolling patients., Findings: Between Sept 19, 2014, and Oct 29, 2015, 305 patients were randomly assigned to pembrolizumab (n=154) or chemotherapy (n=151). Three patients in each group did not complete any PRO instruments at any timepoints, and so 299 patients were included in the full analysis set. Of these patients, one in each group did not complete any PRO instruments before week 15, and so were not included in analyses of change from baseline to week 15. PRO compliance was greater than 90% at baseline and approximately 80% at week 15 for both groups. Least-squares mean baseline-to-week-15 change in QLQ-C30 GHS/QOL score was 6·9 (95% CI 3·3 to 10·6) for pembrolizumab and -0·9 (-4·8 to 3·0) for chemotherapy, for a difference of 7·8 (2·9 to 12·8; two-sided nominal p=0·0020). Fewer pembrolizumab-treated patients had deterioration in the QLQ-LC13 composite endpoint than did chemotherapy-treated patients (46 [31%] of 151 patients vs 58 [39%] of 148 patients). Time to deterioration was longer with pembrolizumab than with chemotherapy (median not reached [95% CI 8·5 to not reached] vs 5·0 months [3·6 to not reached]; hazard ratio 0·66, 95% CI 0·44-0·97; two-sided nominal p=0·029)., Interpretation: Pembrolizumab improves or maintains health-related QOL compared with that for chemotherapy, and might represent a new first-line standard of care for PD-L1-expressing, advanced NSCLC., Funding: Merck & Co., (Copyright © 2017 Elsevier Ltd.

Background: Concurrent chemoradiotherapy is the standard of care in limited-stage small-cell lung cancer, but the optimal radiotherapy schedule and dose remains controversial. The aim of this study was to establish a standard chemoradiotherapy treatment regimen in limited-stage small-cell lung cancer., Methods: The CONVERT trial was an open-label, phase 3, randomised superiority trial. We enrolled adult patients (aged ≥18 years) who had cytologically or histologically confirmed limited-stage small-cell lung cancer, Eastern Cooperative Oncology Group performance status of 0-2, and adequate pulmonary function. Patients were recruited from 73 centres in eight countries. Patients were randomly assigned to receive either 45 Gy radiotherapy in 30 twice-daily fractions of 1·5 Gy over 19 days, or 66 Gy in 33 once-daily fractions of 2 Gy over 45 days, starting on day 22 after commencing cisplatin-etoposide chemotherapy (given as four to six cycles every 3 weeks in both groups). The allocation method used was minimisation with a random element, stratified by institution, planned number of chemotherapy cycles, and performance status. Treatment group assignments were not masked. The primary endpoint was overall survival, defined as time from randomisation until death from any cause, analysed by modified intention-to-treat. A 12% higher overall survival at 2 years in the once-daily group versus the twice-daily group was considered to be clinically significant to show superiority of the once-daily regimen. The study is registered with ClinicalTrials.gov (NCT00433563) and is currently in follow-up., Findings: Between April 7, 2008, and Nov 29, 2013, 547 patients were enrolled and randomly assigned to receive twice-daily concurrent chemoradiotherapy (274 patients) or once-daily concurrent chemoradiotherapy (273 patients). Four patients (one in the twice-daily group and three in the once-daily group) did not return their case report forms and were lost to follow-up; these patients were not included in our analyses. At a median follow-up of 45 months (IQR 35-58), median overall survival was 30 months (95% CI 24-34) in the twice-daily group versus 25 months (21-31) in the once-daily group (hazard ratio for death in the once daily group 1·18 [95% CI 0·95-1·45]; p=0·14). 2-year overall survival was 56% (95% CI 50-62) in the twice-daily group and 51% (45-57) in the once-daily group (absolute difference between the treatment groups 5·3% [95% CI -3·2% to 13·7%]). The most common grade 3-4 adverse event in patients evaluated for chemotherapy toxicity was neutropenia (197 [74%] of 266 patients in the twice-daily group vs 170 [65%] of 263 in the once-daily group). Most toxicities were similar between the groups, except there was significantly more grade 4 neutropenia with twice-daily radiotherapy (129 [49%] vs 101 [38%]; p=0·05). In patients assessed for radiotherapy toxicity, was no difference in grade 3-4 oesophagitis between the groups (47 [19%] of 254 patients in the twice-daily group vs 47 [19%] of 246 in the once-daily group; p=0·85) and grade 3-4 radiation pneumonitis (4 [3%] of 254 vs 4 [2%] of 246; p=0·70). 11 patients died from treatment-related causes (three in the twice-daily group and eight in the once-daily group)., Interpretation: Survival outcomes did not differ between twice-daily and once-daily concurrent chemoradiotherapy in patients with limited-stage small-cell lung cancer, and toxicity was similar and lower than expected with both regimens. Since the trial was designed to show superiority of once-daily radiotherapy and was not powered to show equivalence, the implication is that twice-daily radiotherapy should continue to be considered the standard of care in this setting., Funding: Cancer Research UK (Clinical Trials Awards and Advisory Committee), French Ministry of Health, Canadian Cancer Society Research Institute, European Organisation for Research and Treatment of Cancer (Cancer Research Fund, Lung Cancer, and Radiation Oncology Groups)., (Copyright © 2017 The Author(s).

Background: Pembrolizumab is a humanized monoclonal antibody against programmed death 1 (PD-1) that has antitumor activity in advanced non-small-cell lung cancer (NSCLC), with increased activity in tumors that express programmed death ligand 1 (PD-L1)., Methods: In this open-label, phase 3 trial, we randomly assigned 305 patients who had previously untreated advanced NSCLC with PD-L1 expression on at least 50% of tumor cells and no sensitizing mutation of the epidermal growth factor receptor gene or translocation of the anaplastic lymphoma kinase gene to receive either pembrolizumab (at a fixed dose of 200 mg every 3 weeks) or the investigator's choice of platinum-based chemotherapy. Crossover from the chemotherapy group to the pembrolizumab group was permitted in the event of disease progression. The primary end point, progression-free survival, was assessed by means of blinded, independent, central radiologic review. Secondary end points were overall survival, objective response rate, and safety., Results: Median progression-free survival was 10.3 months (95% confidence interval [CI], 6.7 to not reached) in the pembrolizumab group versus 6.0 months (95% CI, 4.2 to 6.2) in the chemotherapy group (hazard ratio for disease progression or death, 0.50; 95% CI, 0.37 to 0.68; P<0.001). The estimated rate of overall survival at 6 months was 80.2% in the pembrolizumab group versus 72.4% in the chemotherapy group (hazard ratio for death, 0.60; 95% CI, 0.41 to 0.89; P=0.005). The response rate was higher in the pembrolizumab group than in the chemotherapy group (44.8% vs. 27.8%), the median duration of response was longer (not reached [range, 1.9+ to 14.5+ months] vs. 6.3 months [range, 2.1+ to 12.6+]), and treatment-related adverse events of any grade were less frequent (occurring in 73.4% vs. 90.0% of patients), as were grade 3, 4, or 5 treatment-related adverse events (26.6% vs. 53.3%)., Conclusions: In patients with advanced NSCLC and PD-L1 expression on at least 50% of tumor cells, pembrolizumab was associated with significantly longer progression-free and overall survival and with fewer adverse events than was platinum-based chemotherapy.

Background: Creatinine clearance (CrCl) estimation by Cockcroft-Gault calculation (CG) often replaces measurement of glomerular filtration rate (GFR) by [(51)Cr]-ethylenediaminetetraacetic acid clearance (EDTA). Co-morbidity, age, and renal impairment influence the accuracy of CG, whilst the relationship between CG and EDTA has been poorly assessed in lung cancer patients, a population significantly affected by these covariates., Methods: Retrospective analysis of co-morbidity, nephrotoxic drug use, chemotherapy toxicity, and correlation between paired CG and EDTA, in 388 lung cancer and mesothelioma patients receiving platinum-based chemotherapy., Results: Potentially nephrotoxic co-morbidity or medication use occurred in 47% of patients, and was twice as likely in those aged >70 years (OR=2.07; 95%CI: 1.25-3.44, p=0.003). Patients with co-morbidity or nephrotoxic medication use had a lower EDTA compared to those without these baseline factors (p=0.02), but were not significantly more likely to experience chemotherapy toxicity. CG and EDTA correlation was high (r(2)=0.68), but reduced in patients with ETDA<50 ml/min (r(2)=0.26, p=0.02) or >120 ml/min (r(2)=0.32, p=0.09), and in those with CG>120 ml/min (r(2)=0.20, p=0.01). The correlation between CG and EDTA was not significantly altered in patients with co-morbidity or nephrotoxic medication use. CG bias (mean percentage error) and precision (mean absolute percentage error, MAPE) were 7% and 26%, respectively, and precision was impaired in patients with abnormally raised serum creatinine (MAPE 65%, p<0.0001)., Conclusion: CG estimation of CrCl is accurate and safe in lung cancer patients with potentially nephrotoxic co-morbidity or concomitant medication, but should not be used when values are outside the range 50-120 ml/min, or with abnormally elevated serum creatinine., (Copyright © 2011 Elsevier Ireland Ltd.

Introduction: Paraneoplastic neurological disorders are rare complications of breast carcinoma. Lambert-Eaton Myasthenic Syndrome (LEMS) is most commonly associated with small cell lung cancer. However, a combination of LEMS and subacute cerebellar degeneration as paraneoplastic syndromes is extremely rare, and has never been described in association with breast cancer., Case: We report for the first time an unusual association of LEMS and paraneoplastic subacute cerebellar degeneration with breast carcinoma., Conclusion: In patients with atypical LEMS, when there is no evidence of respiratory malignancy, breast cancer should be included in the differential diagnosis.

Introduction: A prespecified analysis of the large, randomized, phase III study in advanced non-small cell lung cancer showed significant improvement in survival for nonsquamous patients treated with pemetrexed/cisplatin versus gemcitabine/cisplatin. Selected grade 3/4 toxicities and resource utilization favored pemetrexed in the overall population, but detailed safety results by histology have not been reported., Methods: Treated patients were included in this analysis of safety by histology. At each cycle, adverse events were assessed, and concomitant medications, transfusions, and hospitalizations were recorded. Measures were summarized by histology and compared between arms with Fisher's exact test., Results: When analyzed by squamous and nonsquamous histology, safety and resource utilization for each treatment arm paralleled those of the overall population. Selected toxicities did not vary by histology. Concomitant medication use and hospitalizations were also very similar to the patterns observed in the overall population., Conclusions: Although previous efficacy analyses showed a significant pemetrexed treatment advantage for nonsquamous patients, results of this analysis indicate that safety and resource utilization do not vary by histology and are consistent with the overall population. The safety and resource utilization of patients treated with pemetrexed/cisplatin are predictable, reproducible, and consistent with the established favorable safety profile of pemetrexed, regardless of histology.

Introduction: Vandetanib is a once-daily oral agent that selectively inhibits vascular endothelial growth factor receptor, epidermal growth factor receptor, and RET (REarranged during Transfection) signaling., Methods: This Phase I study investigated the safety, tolerability, and pharmacokinetics of vandetanib when administered with either gemcitabine plus cisplatin (GC) or vinorelbine plus cisplatin (VC) in patients with previously untreated locally advanced or metastatic non-small cell lung cancer., Results: Seventeen patients received vandetanib 100 mg/d plus VC (n = 9) or GC (n = 8). Three dose-limiting toxicities were reported in each treatment group: vandetanib + VC (pulmonary artery thrombosis and asymptomatic QTc prolongation [n = 2]); vandetanib + GC (peripheral ischemia [due to arterial occlusion], pulmonary embolism, and limb venous thrombosis). The protocol definition of a tolerable dose was not met, and no patients were recruited to receive vandetanib 300 mg plus VC or GC. There was no apparent pharmacokinetic interaction between vandetanib and vinorelbine or gemcitabine, but there was an approximate 30% increase in the exposure to cisplatin, which may be due to accumulation of total platinum and/or an interaction with vandetanib., Conclusions: In this study, in patients with previously untreated advanced non-small cell lung cancer, vandetanib 100 mg/d in combination with either VC or GC was not tolerated.

Background: The epirubicin with cisplatin and infusional 5-fluorouracil (5-FU) (ECisF) regimen was found to be highly active in the treatment of metastatic breast cancer and as neoadjuvant therapy. The UK TRAFIC (trial of adjuvant 5-FU infusional chemotherapy) trial (CRUK/95/007) compared this schedule with 5-FU, epirubicin and cyclophosphamide (FEC60) as adjuvant therapy in patients with early breast cancer., Methods: In this multicentre, open-label, phase III randomised controlled trial, 349 women were randomly assigned to receive i.v. ECisF [epirubicin 60 mg/m(2), day 1, cisplatin 60 mg/m(2), day 1 and 5-FU 200 mg/m(2) by daily 24-h infusion (n = 172)] or FEC [5-FU 600 mg/m(2), day 1, epirubicin 60 mg/m(2), day 1 and cyclophosphamide 600 mg/m(2), day 1 (n = 177)]. Both treatments were delivered every 3 weeks for six cycles. The primary end point was relapse-free interval (RFI). TRAFIC is registered as an International Standard Randomised Controlled Trial (ISRCTN 83324925)., Results: All randomised patients were included in the intent-to-treat population. With a median follow-up of 112 months, there was no significant difference in RFI between the treatment groups [hazard ratio 0.84 (95% confidence interval 0.60-1.19); P = 0.33]. Toxic effects were more frequent in patients allocated to ECisF., Conclusions: While limited by size, TRAFIC has long follow-up. No evidence of a clinically worthwhile benefit for the infusional treatment compared with standard treatment was observed which would justify further investigation or widespread use.

Purpose: Effective treatment options for patients with metastatic breast cancer (MBC) resistant/refractory to anthracyclines and/or taxanes are limited. Intravenous and oral combination of vinorelbine (VRL) and capecitabine were shown to be feasible and effective in first-line MBC. In order to evaluate the activity of the combination of an all oral regimen in a more advanced setting, we investigated a regimen combining oral VRL and capecitabine in a phase II study as second-line chemotherapy of MBC patients previously treated with anthracyclines and taxanes., Patients and Methods: Forty patients (median age 52 years) with MBC received the combination of oral VRL 60 mg/m(2) on days 1, 8 and 15 plus capecitabine 1,000 mg/m(2) bid given from day 1 to day 14 in an open-label, international, multicentre, phase II study. Cycles were repeated every 3 weeks. The primary endpoint was response rate (RR) evaluated by an independent panel review. Secondary objectives included safety, duration of response, progression-free survival, overall survival and quality of life., Results: All the patients had received prior chemotherapy with anthracyclines and taxanes, 75% were refractory/resistant to anthracycline and/or taxane, 72.5% presented with visceral involvement and the last prior chemotherapy for 87.5% of the patients was for advanced disease setting. The median number of administered cycles per patient was 4 (range 1-31). Eight responses were documented and validated by an independent panel review, yielding RRs of 20% [95% CI: 9-35.6] in the intent-to-treat (treated) population and 23.5% [95% CI: 10.7-41.2] in the 34 evaluable patients. Median progression-free survival and median overall survival were 3.4 months [95% CI: 2.3-5.5] and 11.3 months [95% CI: 8.1-16.4], respectively. The principal toxicities were anaemia, neutropenia (rarely complicated; only one patient experienced febrile neutropenia), fatigue and gastrointestinal toxicities with very few grade 3-4 non-haematological toxicities., Conclusions: In second-line treatment of MBC patients previously treated with anthracyclines and taxanes, oral VRL plus capecitabine is a safe regimen with an efficacy comparable to the other available combination regimens used in this heavily and resistant/refractory (75% of patients) pre-treated patients' population. Moreover, this well-tolerated combination offers the advantages of an all oral regimen.

Background: Cancer cells rely on angiogenesis for growth and dissemination, and small cell lung cancer (SCLC) is a highly angiogenic tumor. We evaluated thalidomide, an anti-angiogenic agent, when combined with chemotherapy and as maintenance treatment., Methods: A total of 724 patients (51% with limited and 49% with extensive disease) were randomly assigned to receive placebo or thalidomide capsules, 100-200 mg daily for up to 2 years. All patients received etoposide and carboplatin every 3 weeks for up to six cycles. Endpoints were overall survival, progression-free survival, tumor response rate, toxicity, and quality of life (QoL). Hazard ratios (HRs) for comparing thalidomide against placebo were estimated using Cox regression modeling. Statistical tests were two-sided., Results: The median overall survival was 10.5 months (placebo) and 10.1 months (thalidomide) (HR for death = 1.09, 95% confidence interval [CI] = 0.93 to 1.27; P = .28). Among patients with limited-stage disease, there was no evidence of a survival difference (HR for death = 0.91, 95% CI = 0.73 to 1.15), but among patients with extensive disease, survival was worse in the thalidomide group (HR for death = 1.36, 95% CI = 1.10 to 1.68). Progression-free survival rates were also similar in the two groups (HR = 1.07, 95% CI = 0.92 to 1.24). Thalidomide was associated with an increased risk of having a thrombotic event, mainly pulmonary embolus and deep vein thrombosis (19% thalidomide vs 10% placebo; HR = 2.13, 95% CI = 1.41 to 3.20; P < .001). There were no statistically significant differences between treatments in hematological and nonhematological toxic effects, except more patients in the thalidomide group had rash, constipation, or neuropathy. Overall, QoL scores were similar in the two treatment groups, but thalidomide was associated with less insomnia and diarrhea and more constipation and peripheral neuropathy., Conclusions: In this large randomized trial, thalidomide in combination with chemotherapy did not improve survival of patients with SCLC but was associated with an increased risk of thrombotic events.

Purpose: Data from two randomized phase III trials were analyzed to evaluate prognostic factors and treatment selection in the first-line management of advanced non-small cell lung cancer patients with performance status (PS) 2., Patients and Methods: Patients randomized to combination chemotherapy (carboplatin and paclitaxel) in one trial and single-agent therapy (gemcitabine or vinorelbine) in the second were included in these analyses. Both studies had identical eligibility criteria and were conducted simultaneously. Comparison of efficacy and safety was performed between the two cohorts. A regression analysis identified prognostic factors and subgroups of patients that may benefit from combination or single-agent therapy., Results: Two hundred one patients were treated with combination and 190 with single-agent therapy. Objective responses were 37 and 15%, respectively. Median time to progression was 4.6 months in the combination arm and 3.5 months in the single-agent arm (p < 0.001). Median survival times were 8.0 and 6.6 months, and 1-year survival rates were 31 and 26%, respectively. Albumin <3.5 g, extrathoracic metastases, lactate dehydrogenase >or=200 IU, and 2 comorbid conditions predicted outcome. Patients with 0-2 risk factors had similar outcomes independent of treatment, whereas patients with 3-4 factors had a nonsignificant improvement in median survival with combination chemotherapy., Conclusion: Our results show that PS2 non-small cell lung cancer patients are a heterogeneous group who have significantly different outcomes. Patients treated with first-line combination chemotherapy had a higher response and longer time to progression, whereas overall survival did not appear significantly different. A prognostic model may be helpful in selecting PS 2 patients for either treatment strategy.

Accelerated (dose-dense) chemotherapy, in which the frequency of administration is increased without changing total dose or duration, may increase the efficacy of cancer chemotherapy. We performed a randomised Phase II study to assess the safety and relative toxicity of AC (doxorubicin; cyclophosphamide) vs E(epirubicin)C given by conventional or accelerated schedules as neoadjuvant or adjuvant chemotherapy for early breast cancer. Furthermore, the relative toxicity of doxorubicin and epirubicin remains uncertain. Patients were randomised to one of four arms; four courses of standard 3 weekly cyclophosphamide 600 mg m(-2) in combination with doxorubicin 60 mg m(-2) (AC) vs epirubicin 90 mg m(-2) (EC) 3 weekly vs the same regimens administered every 2 weeks with pegfilgrastim (G-CSF). A total of 126 patients were treated, 42 with standard AC, 42 with accelerated AC, 19 with standard EC and 23 with accelerated EC. Significantly more grade 3/4 day one neutropenia was seen with standard (6/61, 10%) compared to accelerated (0/65,) regimens (P=0.01). A trend towards more neutropenic sepsis was seen in the combined standard and accelerated AC arms (12/84, 14%) compared to the combined EC arms (1/42, 2%), P=0.06. Falls in left ventricular ejection fraction were not increased with accelerated treatment. Accelerated AC and EC with pegfilgrastim are safe and feasible regimens in the treatment of early breast cancer with less neutropenia than conventional 3 weekly schedules.

Background: Malignant pleural mesothelioma is almost always fatal, and few treatment options are available. Although active symptom control (ASC) has been recommended for the management of this disease, no consensus exists for the role of chemotherapy. We investigated whether the addition of chemotherapy to ASC improved survival and quality of life., Methods: 409 patients with malignant pleural mesothelioma, from 76 centres in the UK and two in Australia, were randomly assigned to ASC alone (treatment could include steroids, analgesic drugs, bronchodilators, palliative radiotherapy [n=136]); to ASC plus MVP (four cycles of mitomycin 6 mg/m2, vinblastine 6 mg/m2, and cisplatin 50 mg/m2 every 3 weeks [n=137]); or to ASC plus vinorelbine (one injection of vinorelbine 30 mg/m2 every week for 12 weeks [n=136]). Randomisation was done by minimisation, with stratification for WHO performance status, histology, and centre. Follow-up was every 3 weeks to 21 weeks after randomisation, and every 8 weeks thereafter. Because of slow accrual, the two chemotherapy groups were combined and compared with ASC alone for the primary outcome of overall survival. Analysis was by intention to treat. This study is registered, number ISRCTN54469112., Findings: At the time of analysis, 393 (96%) patients had died (ASC 132 [97%], ASC plus MVP 132 [96%], ASC plus vinorelbine 129 [95%]). Compared with ASC alone, we noted a small, non-significant survival benefit for ASC plus chemotherapy (hazard ratio [HR] 0.89 [95% CI 0.72-1.10]; p=0.29). Median survival was 7.6 months in the ASC alone group and 8.5 months in the ASC plus chemotherapy group. Exploratory analyses suggested a survival advantage for ASC plus vinorelbine compared with ASC alone (HR 0.80 [0.63-1.02]; p=0.08), with a median survival of 9.5 months. There was no evidence of a survival benefit with ASC plus MVP (HR 0.99 [0.78-1.27]; p=0.95). We observed no between-group differences in four predefined quality-of-life subscales (physical functioning, pain, dyspnoea, and global health status) at any of the assessments in the first 6 months., Interpretation: The addition of chemotherapy to ASC offers no significant benefits in terms of overall survival or quality of life. However, exploratory analyses suggested that vinorelbine merits further investigation.

Aims: Palliative chemotherapy in non-small cell lung cancer (NSCLC) has been established since 1995 and little chemotherapy treatment was given to these patients before 1990. This retrospective study investigates the treatment outcome of elderly patients (age>or=70 years) with NSCLC over the past 13 years in a large UK cancer centre., Materials and Methods: A comparison of all-cause survival between the time periods 1990-1994, 1995-1999 and 2000-2004 was adjusted for age, gender, stage and performance status. A comparison of survival was also made between three age groups: 70-74, 75-79 and 80+ years., Results: Between 1990 and 2004, 302 patients>or=70 years had NSCLC. There were differences in age and performance status between the time periods. There was no improvement in median survival between the three time periods (P=0.6). There was little difference in outcome between the three age cohorts., Conclusions: The analysis shows that there has been no significant improvement in survival for elderly patients with advanced lung cancer treated with chemotherapy in the past 13 years.

Immunotherapy with a heat-killed suspension of Mycobacterium vaccae (SRL172), given with chemotherapy, in a phase III trial against non-small-cell-lung cancer showed no improvement in the primary endpoint of survival over chemotherapy alone in the initial published analysis. Compliance was poor, with on average only 53% of patients receiving more than 2 injections in the SRL172 arm of the study. Quality of life was, however, improved in those receiving SRL172. Secondary analyses based on compliance with therapy showed that immunotherapy led to significantly improved survival times of patients with adenocarcinoma but, by contrast, had no beneficial effect on survival times of patients with squamous cell carcinoma. Survival of adenocarcinoma patients receiving SRL172 was increased by a mean of 135 days (p=0.0009, Kaplan-Meier log rank test) and survival after 4 or 5 doses of SRL172 showed a difference of greater than 100 days (p<0.05, Mantel-Hänszel log rank test) in the group receiving SRL172 in addition to chemotherapy. Despite the problems inherent in a secondary analysis, these results encourage further research on the role of killed preparations of adjuvant-rich micro-organisms, including saprophytic mycobacteria such as M. vaccae, and members of related genera in the therapy of a range of cancers.

Introduction: Response rates in the palliative treatment of non-small cell lung cancer, with combination platinum-based chemotherapy, vary from 20% to 40%, leaving a large number with either stable or progressive disease. We examined radiographic response after two courses of platinum-based induction chemotherapy to see whether this is an early predictor of outcome., Methods: In this retrospective study, 320 patients with stage III/IV NSCLC were identified who received 4 or more courses of first-line platinum-based chemotherapy and attained partial response (PR) or stable disease (SD)., Results: After two courses, 115 patients attained PR and 205 SD. Cox regression analysis shows that response after two courses of chemotherapy remains an independent significant prognostic factor for survival. The 2-year survival for patients attaining PR after two courses (n = 115) was 23% compared with 11% (n = 205) for those with SD (p = 0.002). Patients who achieve an objective response after two courses also have a better symptomatic response (p = 0.003) and it was significantly longer (p = 0.04). Of the 205 with SD, 51 attained PR with four courses, whereas 154 (48%) remained with SD; there was no difference in survival outcome of these two groups., Conclusions: These data suggest that NSCLC patients who only have SD after two cycles of first-line chemotherapy have poorer survival outcome and less symptomatic benefit than those in PR. Trials looking at change in management at this point are warranted.

Background: Chemotherapy induced neutropenia has been shown to be associated with improved treatment outcomes in selected solid tumours. We studied the association of chemotherapy induced neutropenia with treatment related outcomes in small cell lung cancer (SCLC)., Methods: This is a retrospective analysis of patients receiving chemotherapy for SCLC at the Royal Marsden Hospital, UK over an 8 year period. The chemotherapy included Carboplatin AUC 5, IV and Etoposide 100mg/m(2) IV on day 1 and 100mg/m(2) PO, B.I.D. on day 2 and 3 every 21 days. Patients were stratified into two groups (A) those experiencing grades 0-2 neutropenia and group (B) those experiencing grades 3-4 neutropenia. The outcomes studied were response rate, time to progression (TTP) and overall survival (OS)., Results: 173 patients were studied. The median age 64 (range 39-83) and M/F ratio was 112:61. The response rates in groups A and B was 90% versus 90%, p=1.0. The median TTP in groups A and B was 30 and 38 weeks, p=0.05. The median OS in groups A and B was 47 weeks versus 60 weeks, p=0.008. The differences in TTP and OS were not significant in patients with extensive stage disease., Conclusions: Occurrence of chemotherapy induced grade 3 or 4 neutropenia correlated with OS in patients with SCLC receiving carboplatin and etoposide chemotherapy. Trials exploring controlled, safe intra-patient dose escalation with the intent of achieving grade 3 or 4 neutropenia in patients with SCLC are warranted.

Background: Phase III studies suggest that non-small-cell lung cancer (NSCLC) patients treated with cisplatin-docetaxel may have higher response rates and better survival compared with other platinum-based regimens. We report the final results of a randomised phase III study of docetaxel and carboplatin versus MIC or MVP in patients with advanced NSCLC., Patients and Methods: Patients with biopsy proven stage III-IV NSCLC not suitable for curative surgery or radiotherapy were randomised to receive four cycles of either DCb (docetaxel 75 mg/m(2), carboplatin AUC 6), or MIC/MVP (mitomycin 6 mg/m(2), ifosfamide 3 g/m(2) and cisplatin 50 mg/m(2) or mitomycin 6 mg/m(2), vinblastine 6 mg/m(2) and cisplatin 50 mg/m(2), respectively), 3 weekly. The primary end point was survival, secondary end points included response rates, toxicity and quality of life., Results: The median follow-up was 17.4 months. Overall response rate was 32% for both arms (partial response = 31%, complete response = 1%); 32% of MIC/MVP and 26% of DCb patients had stable disease. One-year survival was 39% and 35% for DCb and MIC/MVP, respectively. Two-year survival was 13% with both arms. Grade 3/4 neutropenia (74% versus 43%, P < 0.005), infection (18% versus 9%, P = 0.01) and mucositis (5% versus 1%, P = 0.02) were more common with DCb than MIC/MVP. The MIC/MVP arm had significant worsening in overall EORTC score and global health status whereas the DCb arm showed no significant change., Conclusions: The combination of DCb had similar efficacy to MIC/MVP but quality of life was better maintained.

Background: Prior phase II trials have demonstrated the therapeutic activity of cytotoxic chemotherapy in mesothelioma. Currently there are few randomised data assessing the role of chemotherapy versus best supportive care (BSC) in the management of patients with stable symptoms after control of any pleural effusion. A policy of observation is often adopted over initial use of chemotherapy. In this prospective randomised trial we assess the use of early versus delayed cytotoxic therapy. The study opened in 1998, and closed in view of a competing national study (MSO 1) in 2003., Methods: Eligible patients had a performance status3 months and had stable symptoms for at least 4 weeks prior to randomisation. Patients were randomised to receive immediate chemotherapy or initial BSC with the addition of chemotherapy at time of symptomatic progression. All patients received the same platinum-based chemotherapy regimen, MVP [mitomycin C 8 mg/m2 cycles 1, 2, 4 and 6, vinblastine 6 mg/m2, maximum 10 mg, and cisplatin 50 mg/m2 (or carboplatin AUC 5)], every 3 weeks for up to six cycles., Results: A total of 43 patients were recruited, of which 21 were randomised to the early treatment group and 22 to the delayed treatment group. The median ages were 59 years (range 50-78) and 67 years (range 48-75), respectively (P=0.1); other baseline parameters were well matched between the two groups. All 21 patients in the early group received chemotherapy versus 17 patients in the delayed group. Median time to symptomatic progression was 25 weeks in the early group compared with 11 weeks for the delayed group (P=0.1). Median survival was 14 months (1-year survival 66%) for the early group compared with 10 months (1-year survival 36%) for the delayed group (P=0.1). Quality of life was in general better maintained for early treatment and the health resources use was similar in both arms., Conclusions: In this patient group, presenting with stable symptoms after control of pleural effusion, the early use of chemotherapy provided an extended period of symptom control, and in this small trial a trend to survival advantage.

Platinum-based treatment for small cell lung cancer (SCLC) has been established since 1995. This study investigates treatment outcome of elderly patients (age >/=70 years) with SCLC over the past 20 years in a large UK cancer centre. Comparison of all-cause survival was assessed in patients presenting between two predefined time periods: 1982-1994 and 1995-2003. All the survival analysis were adjusted for stage and performance status and age if appropriate. Survival between different chemotherapy treatment regimens was compared. A total of 322 elderly patients (31% of all) registered between 1982-2003 received chemotherapy for SCLC. Patients presenting in 1995-2003 had an overall better median survival (43 vs 25 weeks) and a 1-year survival (37 vs 14%) than patients presenting in 1982-1994 (P<0.001). This applied to patients with both limited and extensive stage disease and all age groups. There was a trend towards the use of more platinum-based treatments in the later cohort but the use of radiotherapy remained constant. Patients who received platinum combinations (Carboplatin or Cisplatin) had significantly improved survival over those who received single agents or other combinations (P<0.001) and there was no significant difference between carboplatin and cisplatin (P=0.7). The analysis demonstrates that there has been a significant improvement in survival for elderly patients with lung cancer treated by chemotherapy in the past 20 years despite more very elderly patients being treated with a poorer performance status. This change is probably multifactorial and may be due to the increased use of platinum-based treatment and improved supportive care.

Background: Vinorelbine is active and well tolerated against advanced breast cancer but there are no published efficacy studies in early breast cancer. We have therefore carried out a randomised phase III neoadjuvant trial in operable breast cancer., Patients and Methods: Patients with > or =3 cm operable breast carcinoma were randomised to receive either vinorelbine 25 mg/m(2) on days 1 and 8 and epirubicin 60 mg/m(2) on day 1, 3 weekly for six cycles (VE) or doxorubicin 60 mg/m(2) and cyclophosphamide 600 mg/m(2) i.v. on day 1, 3 weekly for six cycles (AC), prior to standard local therapy, and adjuvant endocrine therapy as appropriate., Results: A total of 451 patients were randomised. Results for AC and VE, respectively, were: overall clinical response 73% and 74%, complete clinical remission 20% and 24%, pathological complete remission 12% and 12%, mastectomy rate 52% and 55%. None of these differences were significant. Dose reduction was required in 8% for AC and 20% for VE (P <0.001) (GSCF support not used). Significantly more grade 3/4 toxicity for nausea, vomiting and alopecia (despite scalp cooling) was seen for AC compared with VE but significantly less grade 3/4 thrombophlebitis and neuropathy., Conclusions: Neoadjuvant VE is as effective as AC in early breast cancer and was better tolerated except for thrombophlebitis and neuropathy.

Background: Recent dose-intensity studies of small-cell lung cancer (SCLC) have yielded conflicting results. We carried out a phase III randomized trial in patients with better-prognosis SCLC (i.e., prognostic score of 0-1) to investigate whether doubling the dose density of ifosfamide, carboplatin, and etoposide (ICE) chemotherapy with filgrastim and blood-progenitor-cell support improves survival, compared with standard ICE chemotherapy., Methods: We studied 318 patients with pathologically proven SCLC who were randomly assigned to receive six cycles of ICE chemotherapy with a 4-week (standard arm) or 2-week (dose-dense arm) interval between cycles. Patients in the dose-dense arm received filgrastim subcutaneously daily on days 4 through 14 and had autologous blood collected before cycles 2 through 6, which was returned 24 hours after treatment. Toxicities, including hematologic toxicity and incidence of neutropenic sepsis, were monitored. Survival was calculated by the Kaplan-Meier method. All statistical tests were two-sided., Results: The delivered median dose intensity was 99% (interquartile range = 96%-100%) for the standard arm and 182% (interquartile range = 163%-196%) for the dose-dense arm. After a median follow-up of 14 months, overall response to treatment was observed in 118 (80%) of the 148 evaluable patients in the standard arm and in 129 (88%) of the 147 evaluable patients in the dose-dense arm, a statistically non-significant difference. Median overall survival was 13.9 months (95% confidence interval [CI] = 12.9 to 15.8 months) in the standard arm and 14.4 months (95% CI = 12.7 to 16.0) in the dose-dense arm, and the 2-year survival was 22% (95% CI = 16% to 29%) and 19% (95% CI = 14% to 27%), respectively--neither difference being statistically significant. The median treatment free time was 286 days (95% CI = 229 to 343 days) for the standard arm and 367 days (95% CI = 321 to 413 days) for the dose-dense arm (difference = 81 days; P = .109). Statistically significantly more hematologic toxicity was reported in the dose-dense arm than in the standard arm, but the number of cycles complicated by neutropenic sepsis was statistically significantly higher in the standard arm than in the dose-dense arm (15.3% versus 11.6%, respectively; difference = 3.7%, 95% CI = -4.1% to 11.5%; P = .03)., Conclusions: Dose-dense ICE chemotherapy for SCLC led to shorter treatment duration and less neutropenic sepsis than did standard ICE but did not improve overall survival.

Lung cancer is the most prevalent, yet most preventable malignancy worldwide. Given the tendency of small cell lung cancer (SCLC) to early relapse and its subsequent resistance to treatment, there is an urgent need to optimize standard treatment strategies and develop new treatments. Over the last decade, several strategies have been adopted and advances in the molecular biology of lung cancer have identified a number of targets for future therapy. In this article, we review chemotherapy strategies that have been evaluated in the management of patients with SCLC.

Purpose: To determine efficacy and toxicity of two pemetrexed-based regimens in chemonaive patients with locally advanced or metastatic non-small cell lung cancer., Experimental Design: Patients were randomly assigned to receive pemetrexed 500 mg/m(2) plus oxaliplatin 120 mg/m(2) (PemOx) or pemetrexed plus carboplatin AUC6 (PemCb). All drugs were given on day 1 of a 21-day cycle for up to six cycles. Folic acid and vitamin B(12) were given to all patients to minimize pemetrexed-related toxicities., Results: Forty-one patients received PemOx and 39 received PemCb. Objective tumor response rates were 26.8% for PemOx patients (95% confidence interval, 14.2-42.9) and 31.6% for PemCb patients (95% confidence interval, 17.5-48.7). Median time to progression was 5.5 and 5.7 months, respectively, for PemOx and PemCb. Median overall survival times were 10.5 months for both treatment groups (range, <1 to >20 months). The 1-year survival rate was 49.9% for PemOx patients and 43.9% for PemCb patients. Common toxicity criteria grade 3 or 4 hematologic toxicities among PemOx patients were grade 3 or 4 neutropenia (7.3%), grade 3 thrombocytopenia (2.4%), and grade 3 anemia (2.4%). PemCb patients experienced grade 3 or 4 neutropenia (25.6%), grade 3 or 4 thrombocytopenia (17.9%), and grade 3 anemia (7.7%). Grade 3 vomiting occurred in three PemOx patients and grade 3 fatigue occurred in three PemCb patients. One grade 3 neurosensory toxicity occurred in the PemOx group. Three patients (PemOx 1 and PemCb 2) experienced febrile neutropenia., Conclusions: Efficacy measures for both regimens seem similar to the most effective chemotherapies for advanced non-small cell lung cancer (platinum combinations) with less hematologic and nonhematologic toxicity. Comparing either of these two regimens to platinum-based therapies in a large randomized trial is warranted.

Background: With the rising incidence of malignant mesothelioma (MM), it is important to optimise treatment to control symptoms, maintain quality of life and, if possible, prolong life. We have analysed prospectively collected data to evaluate a frequently used palliative chemotherapy regimen., Patients and Methods: Between October 1986 and May 2002 all patients with inoperable pleural mesothelioma were considered for treatment with MVP (mitomycin C 8 mg/m2 every 6 weeks, vinblastine 6 mg/m2 every 3 weeks and cisplatin 50 mg/m2 every 3 weeks) chemotherapy. Symptoms were assessed by physician assessment at baseline and after each cycle of chemotherapy., Results: One hundred and fifty patients were treated with MVP for mesothelioma. Forty-three per cent had a performance status (PS) 2 or worse. The response rate was 15.3%, with 68.6% having stable disease. Sixty-nine per cent reported an improvement in symptoms; in particular there were good responses for pain (71%), cough (62%) and dyspnoea (50%). The most common grade 3/4 toxicity was neutropenia (22%). Median overall survival was 7 months, with 1-year survival 31% and 2-year survival 11%. Median survival for patients with PS 0/1 was 10 months, and was 6 months for patients with PS 2/3. Poor prognostic factors in univariate analysis included poor PS, weight loss, mixed or sarcomatoid histology, low haemoglobin and high white blood cell count. Excluding pathological subtype, the prognostic significance of poor PS and weight loss were retained in multivariate analysis., Conclusions: Palliation of symptoms in MM is achievable with current cisplatin-based treatments.

Background: Vinorelbine and carboplatin are both active agents in the treatment of non-small-cell lung cancer (NSCLC). Vinorelbine has recently been developed in an oral formulation, which is as active as the intravenous (i.v.) form., Patients and Methods: Fifty-two chemonaive patients with unresectable localised or metastatic NSCLC received i.v. vinorelbine 25 mg/m(2) plus carboplatin (AUC 5) on day 1 and oral vinorelbine 60 mg/m(2) on day 8 (or day 15 if neutrophils <1500/mm(3)) every 3 weeks in an open-label, multicentre phase II study., Results: A total of 224 cycles were given, with the median number per patient of four (range one to eight). Eight responses out of 52 enrolled patients were documented and validated by an independent panel review, yielding a response rate of 18.2% [95% confidence interval (CI) 6.8-29.6%] in the evaluable population. This response rate was balanced by a high rate of disease control (78.9% in the intention-to treat population and 90.9% in the evaluable population). The median progression-free and median survival were 5.1 months (95% CI 4.3-8.1) and 9.3 months (95% CI 6.8-11.4), respectively. Overall, the safety profile of the combination regimen alternating i.v. and oral vinorelbine appeared similar to that expected for each individual agent. Some lung cancer-specific items (pain, dyspnoea) improved or were stabilised by assessment using the EORTC QLQ-C30 and QLQ-LC13 questionnaires., Conclusions: The combination of carboplatin with an alternating regimen of i.v./oral vinorelbine is a well tolerated regimen with a low level of toxicity and a low rate of serious adverse events. A high rate of disease control (partial response + no change) was achieved. Progression-free survival and overall survival fell within the expected range. This regimen is convenient and safe for the treatment of patients with locally advanced or metastatic NSCLC patients.

To examine whether weight loss at presentation influences outcome in patients who received chemotherapy for lung cancer or mesothelioma. Multivariate analysis of prospectively collected data 1994-2001. Data were available for age, gender, performance status, histology, stage, response, toxicity, progression-free and overall survival. The outcomes of patients with or without weight loss treated with chemotherapy for small cell lung cancer (SCLC; n=290), stages III and IV non-small-cell lung cancer (NSCLC; n=418), or mesothelioma (n=72) were compared. Weight loss was reported by 59, 58 and 76% of patients with SCLC, NSCLC and mesothelioma, respectively. Patients with weight loss and NSCLC (P=0.003) or mesothelioma (P=0.05) more frequently failed to complete at least three cycles of chemotherapy. Anaemia as a toxicity occurred significantly more frequently in NSCLC patients with weight loss (P=0.0003). The incidence of other toxicities was not significantly affected by weight loss. NSCLC patients with weight loss had fewer symptomatic responses (P=0.001). Mesothelioma patients with weight loss had fewer symptomatic (P=0.03) and objective responses (P=0.05). Weight loss was an independent predictor of shorter overall survival for patients with SCLC (P=0.003, relative risk (RR)=1.5), NSCLC (P=0.009, RR=1.33) and mesothelioma (P=0.03, RR=1.92) and an independent predictor of progression-free survival in patients with SCLC (P=0.01, RR=1.43). In conclusion, weight loss as a symptom of lung cancer predicts for toxicity from treatment and shorter survival.

Background: To compare the efficacy of continuous infusional 5-fluorouracil (5-FU)-based chemotherapy against conventional bolus chemotherapy in the preoperative treatment of patients with large operable early breast cancer., Patients and Methods: Four hundred and twenty-six women with histologically proven 3 cm invasive early breast cancer were randomised to receive pre-operative infusional 5-FU 200 mg/m(2) by daily 24 h continuous infusion via a Hickman line for 18 weeks with epirubicin 60 mg/m(2) intravenous (i.v.) bolus on day 1 and cisplatin 60 mg/m(2) i.v. bolus on day 1, both repeating 3-weekly (infusional ECisF), or conventional bolus doxorubicin 60 mg/m(2) i.v. on day 1 and cyclophosphamide 600 mg/m(2) i.v. on day 1, both repeating 3-weekly (AC), both schedules for six courses. Patients subsequently had local therapy (surgery or radiotherapy or both) and tamoxifen 20 mg orally daily as appropriate., Results: The 5 year results for AC and infusional ECisF, respectively, were as follows: overall response, 75% and 77%; complete clinical remission, 31% and 34%; pathological complete remission (pathCR), 16% for both; and pathCR with residual ductal carcinoma in situ (DCIS), 25% and 24%. Mastectomy rates were 37% and 34%, respectively. Five-year overall survival was 74% for AC and 82% for infusional ECisF (hazard ratio 0.76, 95% confidence interval 0.51-1.13; P = 0.18). Both treatments were well tolerated. Grade III/IV lethargy, vomiting, alopecia and plantar-palmar erythema were significantly greater for infusional ECisF; grade III/IV leucopenia was significantly greater for AC., Conclusions: Preoperative continuous infusional 5-FU-based chemotherapy is no more active than conventional AC for early breast cancer; with a median 5 year follow-up, the infusion-based schedule shows a non-significant trend towards improved survival.

Objective: To analyse the long-term efficacy of combined interferon-alpha (IFN-alpha) and interleukin-2 (IL-2) subcutaneously, with 5-fluorouracil (5-FU) intravenously in a general multicentre setting, as treatment for metastatic renal cell carcinoma (RCC)., Methods: Fifty-nine patients with metastatic RCC were scheduled to receive an 8-week cycle of immunotherapy. Karnofsky score ranged from 70 to 100 (median 90). Thirty-one patients at presentation had metastases of which 14 underwent nephrectomy. Metastases occurred in multiple organs (lung 74%, mediastinal lymphadenopathy 22%, bone 21%). Therapeutic response and survival were analysed., Results: Nine patients died from disease progression prior to completion of one full cycle. Six cases (10%) have stable disease at a follow-up of 51 months (range 20-88 months). Currently 11 patients (19%) are alive at a mean follow-up of 45 months (range 18-88 months). Forty-eight patients (81%) died of their disease at a mean follow-up of 10 months (range 0.5-46 months). Survival rate at 1 year was 53%, at 2 years 21%, at 3 years 16% and at 5 years 5%. Overall median survival is 10 months., Conclusion: IL-2 and IFN-alpha with 5-FU based immunotherapy achieve durable survival rates at 3 years in a minority of patients. Addition of 5-FU does not increase survival in our group. This study population is very different to other reported series. However it reflects better the entire population with metastatic RCC though results are subsequently poorer. Identifying patients that will respond is paramount.

Background: The incidence of mesothelioma is rising rapidly in the UK. There is no generally accepted standard treatment. The BTS recommends active symptom control (ASC). It is not known whether chemotherapy in addition prolongs survival or provides worthwhile palliation with acceptable toxicity. Palliation as recorded by patients has been fully reported for only two regimens: mitomycin, vinblastine, and cisplatin (MVP), and vinorelbine (N). The BTS and collaborators planned to conduct a phase III randomised trial comparing ASC only, ASC+MVP, and ASC+N in 840 patients with survival as the primary outcome measure. The aim of the present study was to assess the acceptability of the trial design to patients and the suitability of two standard quality of life (QL) questionnaires for mesothelioma., Methods: Collaborating centres registered all new patients with mesothelioma. Those eligible and giving informed consent completed EORTC QLQ-C30+LC13 and FACT-L QL questionnaires and were randomised between all three or any two of (1) ASC only, (2) ASC+4 cycles of MVP, and (3) ASC+12 weekly doses of N., Results: During 1 year, 242 patients were registered of whom 109 (45%) were randomised (55% of the 197 eligible patients). Fifty two patients from 20 centres were randomised to an option including ASC only. This translates into a rate of 312 per year from 60 centres interested in collaborating in the phase III trial. The EORTC QL questionnaire was superior to FACT-L in terms of completeness of data and patient preference. Clinically relevant palliation was achieved with ASC., Conclusion: The planned phase III trial is feasible.

The aim of this study was to document the activity and toxicity of paclitaxel (Taxol)/carboplatin when used as induction chemotherapy in patients with stage IIIA N2 non-small cell lung cancer (NSCLC) prior to definitive local treatment within a large, ongoing comparative study (EORTC 08941). 52 eligible, consenting, chemotherapy-naïve patients with NSCLC, median age of 60 years, stage IIIA N2 disease and the ability to tolerate a pneumonectomy received paclitaxel 200 mg/m2 as a 3-h infusion followed by carboplatin at an area under the concentration curve (AUC) of 6 every 3 weeks for three courses. Most patients received three courses. No grade 3/4 anaemia or thrombocytopenia was documented. Over all of the cycles, 6% (3 patients) experienced grade 3 leucopenia while 63% (32/51 patients) experienced grade 3-4 neutropenia. There was 1 patient (2%) with febrile neutropenia, no early or toxic deaths and no hypersensitivity reactions. Severe non-haematological toxicity was uncommon, with the exception of grade 3 alopecia in 39%, lethargy in 8% and myalgia in 6%. Of the eligible patients (n=52), there was one complete response (CR) and 32 partial responses (PR), resulting in a response rate of 64% (95% Confidence Interval (CI) 49%-76%). Of the 15 eligible patients randomised to surgery after induction chemotherapy, 3 patients did not receive surgery and 2 patients (n=12) had no tumour in the mediastinal nodes (17%). Resections were considered complete in 2 of the 12. Median survival for all eligible patients (n=52) was 20.5 months (95% CI 16.1-31.2), with an estimated 1-year survival rate of 68.5% (95% CI 55.2-81.7). In patients with N2 stage IIIA NSCLC, paclitaxel/carboplatin is an active and very well-tolerated induction regimen.

Aim: The aim of this study was to evaluate the activity of the combination of carboplatin and vinorelbine in patients with poor prognosis small cell lung cancer (SCLC). Patients with good prognosis disease were included who were not medically fit to tolerate conventional chemotherapy. Activity was assessed primarily as response rate and secondarily in terms of toxicity, time to progression and survival., Patients and Methods: Fifty-eight patients, 37 men and 21 women, with histologically or cytologically confirmed SCLC, who had bi-dimensionally measurable disease, with ECOG performance status > or = 2, with adequate haematological, hepatic and renal function received first-line chemotherapy with carboplatin (AUC x 5) day 1 and vinorelbine (30 mg/m2) days 1 and 8 of a 28-day cycle. Response was assessed after every two cycles of chemotherapy, with patients receiving a maximum of six cycles of treatment., Results: The combination of carboplatin and vinorelbine is an active regimen in the treatment of SCLC, with an overall intention-to-treat response rate of 55% [95% confidence interval (CI): 42-68%] with six (10%) of patients having a complete response. Median time to progression was 18 weeks (95% CI: 15-21 weeks). Median overall survival was 26 weeks (95% CI: 21-31 weeks). Ten patients failed to complete two cycles of treatment, and were not evaluable for response for the following reasons: septic death (1 neutropaenic, 1 no myelotoxicity), non-toxic death (1 tumour eroded through the pulmonary artery, 1 ischaemic heart disease) ischaemic heart disease (1) and patient decision (5). There were a total of three toxic deaths all sepsis-complicating neutropaenia. Forty-four (76%) patients experienced grade 3 or 4 neutropaenia, six (11%) grade 3 or 4 thrombocytopaenia, 10 (13%) grade 3 lethargy, three (5%) grade 3 nausea and two (3%) grade 3 diarrhoea., Conclusions: The combination of carboplatin and vinorelbine is active against SCLC but the toxicity profile in this group of patients suggests that further evaluation is not appropriate.

Purpose: To compare protracted venous infusion (PVI) fluorouracil (5-FU) with PVI 5-FU plus mitomycin (MMC) in patients with advanced pancreatic cancer in a multicenter, prospectively randomized study., Patients and Methods: Two hundred eight patients were randomized to PVI 5-FU (300 mg/m(2)/d for a maximum of 24 weeks) or PVI 5-FU plus MMC (7 mg/m(2) every 6 weeks for four courses). The major end points were tumor response, survival, toxicity, and quality of life (QOL)., Results: The two treatment groups were balanced for baseline demographic factors, and 62% had metastatic disease. The overall response rate was 8.4% (95% confidence interval [CI]) 3.2% to 13.7% for patients treated with PVI 5-FU alone compared with 17.6%; 95% CI 10.3% to 25.1% for PVI 5-FU plus MMC (P =.04). Median failure-free survival was 2.8 months for PVI 5-FU and 3.8 months for PVI 5-FU plus MMC (P =.14). Median survival was 5.1 months for PVI 5-FU and 6.5 months for PVI 5-FU plus MMC (P =.34). Toxicities in both arms were mild. There was an increased incidence of neutropenia in the 5-FU plus MMC arm (P <.01), although no differences in infection were seen. No patients developed hemolytic uremic syndrome. Global QOL improved significantly after 24 weeks of treatment compared with baseline for patients receiving 5-FU plus MMC, although there was no statistically significant difference in QOL between arms., Conclusion: PVI 5-FU plus MMC resulted in a superior response rate in comparison with PVI 5-FU alone in advanced pancreatic cancer, but this did not translate into a survival advantage. These results emphasize the importance of chemotherapy in this setting and the continuing value of the fluoropyrimidines in pancreatic cancer.

The objectives of this study were to determine the toxicity of intratumoural/intrapleural SRL172 in addition to intradermal SRL172 and standard chemotherapy (mitomycin-C, vinblastine and cisplatin) in patients with malignant mesothelioma. Patients received chemotherapy (mitomycin-C: 8 mg m(-2), vinblastine: 6 mg m(-2), cisplatin 50 mg m(-2)) on a 3-weekly basis for up to six courses. IP SRL172 injections were given 3-weekly prior to chemotherapy and escalated in groups of three patients from 1 microg to 1 mg bacilli in 10-fold increments. Patients were also given ID SRL172 at a dose of 1 mg bacilli 4-weekly. Patients were assessed for toxicity after each course of chemotherapy and for response by CT imaging. Immuno-haematological parameters were analyzed pre-treatment and 1 month after completion of treatment. There was no dose limiting toxicity with IP SRL172 although there was greater toxicity at the highest dose (n=13). There were six out of 16 partial responses (37.5%). Haemato-immunological parameters, measured in seven patients pre and post-therapy, revealed that response rate correlated with a decrease in platelet count and there was an increase in activation of natural killer cells and a decrease in the percentage of IL-4 producing T cells in all tested patients post-treatment. SRL172 can be given safely into tumour deposits and the pleural cavity in patients with malignant mesothelioma and we have established the dose for phase II testing., (Copyright 2002 The Cancer Research Campaign)

Purpose: So far there are no published data on optimal duration of chemotherapy for advanced non-small-cell lung cancer (NSCLC); six or more courses are usually recommended. We have carried out a multicenter randomized trial comparing three versus six courses of chemotherapy., Patients and Methods: Patients with stage IIIb or IV NSCLC were randomized at start of treatment to receive either three or six courses of mitomycin 8 mg/m(2) (courses 1, 2, 4, and 6), vinblastine 6 mg/m(2), and cisplatin 50 mg/m(2) (MVP) every 21 days. Treatment was stopped early in both arms for progressive disease or unacceptable toxicity. Key end points were overall survival, duration of symptom relief, and quality-of-life assessment using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 with lung cancer-specific module QLQ-LC13., Results: Three hundred eight patients were randomized. Seventy-two percent of the 155 patients randomized to three courses completed treatment. In the 153 patients randomized to six courses, 73% completed three courses and 31% six courses. Median survival was 6 versus 7 months, respectively, and 1-year survival 22% versus 25% (P =.2). Median duration of symptom relief was 4.5 months (both arms), and 8% versus 18% had continuing symptom relief (P =.4). Quality-of-life parameters were the same or improved for patients randomized to only three courses, including significantly decreased fatigue (P =.03) and a trend toward decreased nausea and vomiting (P =.06)., Conclusion: Our findings show no evidence for additional clinical benefit by continuing MVP chemotherapy beyond three courses. This challenges current orthodoxy of six courses or more. Further trials addressing duration of chemotherapy are now warranted, particularly with newer chemotherapy schedules.

The majority of patients diagnosed with non-small cell lung carcinoma (NSCLC) present with advanced disease and, as such, are treated with palliative intent. Platinum-based combination chemotherapy plays an important role in the management of these patients, with response rates to most regimens being in the range of 30%-40%. with symptom relief in up to 60%. One of the most commonly utilized combinations is mitomycin C, vinblastine and cisplatin (MVP). Owing to the hydration regimen, and to the age and performance status of many of these patients, in reality this combination often necessitates an overnight stay in hospital. A combination of drugs that could be administered as an outpatient would be beneficial to patients and could result in substantial economic benefits. Forty-three patients with Stage IlIb and IV NSCLC were treated with the MVCarbo regimen, in which the cisplatin in the MVP regimen was replaced with carboplatin. All treatment was administered on an outpatient basis. The overall objective response rate was 30%; the symptomatic response rate was 60%, which was exactly equivalent to the response rate seen in a comparable group of patients treated with MVP in a trial on duration of chemotherapy at the Royal Marsden Hospital. There was no difference in progression-free or overall survival between patients treated with the two regimens. The MVCarbo regimen resulted in response rates and survival rates equivalent to those seen with standard MVP and, as such, provides an acceptable outpatient alternative to this treatment.

Mycobacterial preparations have been used with limited success against cancer apart from superficial bladder cancer. Recently, a therapeutic vaccine derived from Mycobacterium vaccae has been given to patients with prostate cancer and melanoma indicating a possible beneficial effect on disease activity in such patients. We have recently initiated a series of randomized studies to test the feasibility and toxicity of combining a preparation of heat-killed Mycobacterium vaccae (designated SRL172) with a multidrug chemotherapy regimen to treat patients with inoperable non-small cell lung cancer (NSCLC) and mesothelioma. 28 evaluable patients with previously untreated symptomatic NSCLC and mesothelioma were randomized to receive either 3 weekly intravenous combination chemotherapy alone, or chemotherapy given with monthly intra-dermal injections of SRL172. Safety and tolerability were scored by common toxicity criteria and efficacy was evaluated by survival of patients and by tumour response assessed by CT scanning. The toxicity of chemotherapy was similar in the two groups. SRL172 caused mild inflammation at the injection site. In the group of patients randomized to receive chemotherapy combined with SRL172, there was a trend towards improved response rate (54% vs. 33%) with more patients in the combined arm receiving radical surgery and radiotherapy, improved median survival (9.7 months vs. 7.5 months) and improved 1 year survival (42% vs. 18%). SRL172 appeared to improve sleep (P = 0.08) and improved appetite (P = 0.01). There was no detectable change in serum cytokine levels for gamma-interferon and TNF-alpha before and after treatment. In patients with NSCLC and mesothelioma, there may be a beneficial interaction when chemotherapy is administered in combination with SRL172. Confirmation of this effect and further investigation is underway in a randomized phase III trial and in laboratory models., (Copyright 2000 Cancer Research Campaign.)

Cancer patients receiving cytotoxic chemotherapy often become anaemic and may require blood transfusions. A large-scale audit of patients with a variety of solid tumours receiving chemotherapy at 28 specialist centres throughout the UK was undertaken to quantify the problem. Data were available from 2719 patients receiving 3206 courses of cytotoxic chemotherapy for tumours of the breast (878), ovary (856), lung (772) or testis (213). Their mean age was 55 years (range 16-87). Overall, 33% of patients required at least one blood transfusion but the proportion varied from 19% for breast cancer to 43% for lung. Sixteen per cent of patients required more than one transfusion (7% for breast, 22% in lung). The mean proportion of patients with Hb < 11 g dl(-10 rose over the course of chemotherapy from 17% before the first cycle, to 38% by the sixth, despite transfusion in 33% of patients. Of the patients receiving transfusions, 25% required an inpatient admission and overnight stay. The most common symptoms reported at the time of transfusion were lethargy, tiredness and breathlessness. Further research is needed to evaluate the role of blood transfusions in patients receiving cytotoxic chemotherapy.

Surgical resection offers the best chance for cure for early stage non-small-cell lung cancer (NSCLC, stage I, II, IIIA), but the 5-year survival rates are only moderate, with systemic relapse being the major cause of death. Pre-operative (neo-adjuvant) chemotherapy has shown promise in small trials restricted to stage IIIA patients. We believe similar trials are now appropriate in all stages of operable lung cancer. A feasibility study was performed in 22 patients with early stage (IB, II, IIIA) resectable NSCLC; randomized to either three cycles of chemotherapy [mitomycin-C 8 mg m(-2), vinblastine 6 mg m(-2) and cisplatin 50 mg m(-2) (MVP)] followed by surgery (n = 11), or to surgery alone. Of 40 eligible patients, 22 agreed to participate (feasibility 55%) and all complied with the full treatment schedule. All symptomatic patients achieved either complete (50%) or partial (50%) relief of tumour-related symptoms with pre-operative chemotherapy. Fifty-five per cent achieved objective tumour response, and a further 27% minor tumour shrinkage; none had progressive disease. Partial pathological response was seen in 50%. No severe (WHO grade III-IV) toxicities occurred. No significant deterioration in quality of life was detected during chemotherapy. Pre-operative MVP chemotherapy is feasible in early stage NSCLC, and this study has now been initiated as a UK-wide Medical Research Council phase III trial.

The intention of this study was to identify the pretreatment characteristics predicting for the survival, objective response and symptom relief in patients with non-resectable, non-small-cell lung cancer (NSCLC) managed in the Lung Unit at the Royal Marsden Hospital. This analysis included 290 patients with advanced NSCLC generally treated with a cisplatin-based chemotherapy regimen in one of a series of trials. Thirty-seven pretreatment variables, response and survival data were collected prospectively and analysed using univariate and multivariate methods. By multivariate analysis performance status, disease extent and pattern of metastases along with certain biochemical features were influential independent variables for survival, objective and symptom response. Older age was positively associated with objective response (P = 0.04). When the independent factors for symptom response were used to group patients into prognostic categories, 30-48% of patients with an adverse set of factors had symptom relief. Similarly using the relative risk of death to subgroup the patient population, 54% of patients at high risk of death (greater than 8.0), with a median survival of 2.5 months, had symptom relief. The data are consistent with other studies in identifying the pretreatment factors predicting for survival and objective response. Additionally, older age is positively associated with objective response and the majority of patients with the worst prognosis have symptom relief from treatment with chemotherapy.

MVP chemotherapy (mitomycin C 8 mg m(-2), courses 1, 2, 4 and 6, vinblastine 6 mg m(-2), cisplatin 50 mg m(-2)) is an active low-toxicity regimen in non-small-cell lung cancer (NSCLC). Based on the single-agent activity of these agents in SCLC, we have conducted a phase II trial of MVP in SCLC. Fifty chemo-naive patients with SCLC were entered in this trial. There were 33 men and 17 women with median age 66 years (range 46-83 years); 18 patients had limited disease (LD) and 32 extensive disease (ED). WHO performance status (PS) was: three patients PS 0, 33 patients PS 1, ten patients PS 2, four patients PS 3. A maximum of six cycles was given in responding patients. On completion of chemotherapy, patients with LD obtaining complete response (CR)/good partial response (PR) received thoracic irradiation and those obtaining CR were offered entry into the ongoing MRC Prophylactic Cranial Irradiation Trial. The overall response was 79% with 17% CR and 62% PR. For LD patients, 38% obtained CR but for ED only one patient achieved CR. Median response duration for LD patients was 8 months and for ED patients 5 months. Median survival was 10 months for LD patients and 6 months for ED patients. There was complete resolution of symptoms in 24%, partial improvement in 68%, no change in 2% and progressive symptoms in 6%. As regards toxicity, 24% developed WHO grade 3/4 neutropenia, 16% grade 3/4 thrombocytopenia and 6% significant hair loss. Two patients died during the first week of treatment with neutropenic infection. Quality of life using the EORTC questionnaire (QLC-C30) with lung cancer module demonstrated significant improvements from baseline levels in emotional and cognitive functioning, global QOL, of pain, dyspnoea and cough. MVP, an effective palliative regimen for NSCLC, is also active against SCLC with low toxicity and merits comparison with more toxic conventional schedules.
