Simple Summary: Breast cancer is one of the most common oncological diseases among women in Western Countries and Italy as well. GIM 13-AMBRA is a patient journey study regarding how the prognosis of metastatic breast cancer patients has changed in the last decades as a result of the introduction of new drugs in clinical practice. This study also provides information regarding the different natural histories of breast cancer according to the presence or absence of hormone receptors and HER2 receptors. GIM 13-AMBRA is a longitudinal cohort study aimed at describing therapeutic strategies and the relative outcome parameters in 939 HER2-ve MBC patients. Taxanes–based regimens, or taxanes + targeted agents, mainly Bevacizumab, were the preferred first choice in both Luminal (30.2%) and TNBC (33.3%) patients. The median PFS1 was 12.5 months (95% CI 16.79–19.64), without any significant difference according to subtypes, while the median Time to first Treatment Change (TTC1) was significantly lower in TNBC patients (7.7 months—95% CI 5.7–9.2) in comparison to Luminal A (13.2 months, 95% CI 11.7–15.1) and Luminal B patients (11.8 months, 95% CI 10.3–12.8). PFS2 was significantly shorter in TNBC patients (5.5 months, 95% CI 4.3–6.5 vs. Luminal A—9.4, 95% CI 8.1–10.7, and Luminal B—7.7 95% CI 6.8–8.2, F-Ratio 4.30, p = 0.014). TTC2 was significantly lower in patients with TNBC than in those with the other two subtypes. The median OS1 was 35.2 months (95% CI 30.8–37.4) for Luminal A patients, which was significantly higher than that for both Luminal B (28.9 months, 95% CI 26.2–31.2) and TNBC (18.5 months, 95% CI 16–20.1, F-ratio 7.44, p = 0.0006). The GIM 13—AMBRA study is one of the largest collections ever published in Italy and provides useful results in terms of time outcomes for first, second, and further lines of treatment in HER2- MBC patients.

Simple Summary: The treatment of advanced NSCLC patients unfit for a platinum combination is challenging and no clear evidence is available. We retrospectively collected data on advanced NSCLC not receiving a first-line platinum combination, focusing on clinical selection criteria. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included. Median age was 79 (range 56–92) years, M/F 165(74.6%)/56(25.4%), ECOG performance status (PS) 0/1/ ≥ 2 23(10.9%)/94(42.5%)/103(46.6%), with a median of two serious comorbidities. A median of 25% (range 10%-30%) of newly diagnosed NSCLC did not receive a first-line platinum combination. Clinical criteria according to which decision was made were older age (76.5%), comorbidities (72%), poor PS (55.2%) and familiar or social issues (10%). Single-agent treatment consisted of oral metronomic vinorelbine (MetV 78.6%), gemcitabine (Gem 10%), oral standard vinorelbine (Vin 8.2%) and other (O 3.2%). Median progression-free survival (PFS) and overall survival (OS) of single agent treatments ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. All grade toxicities did not differ among single agents, while grade 3–4 toxicities were less frequent with MetV. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor PS. An oral treatment was frequently proposed with MetV being the most frequent choice according to its safety profile. [ABSTRACT FROM AUTHOR]

Background: EOX (epirubicin, oxaliplatin, and capecitabine) is one of the standard regimens for metastatic or locally advanced gastric cancer (GC). A new combination based on fractional docetaxel (low-TOX) has been developed in an attempt to increase the efficacy of EOX and reduce the heavy toxicity of classical docetaxel regimens. Methods: Overall, 169 previously untreated GC patients were randomized between EOX (arm A) and low-TOX (arm B). The primary endpoint was progression-free survival (PFS), while secondary ones were overall survival (OS), overall response rate (ORR), disease control rate (DCR), and tolerability. The study was designed to detect a 35% (80% power at a two-sided 5% significance level) PFS increase with low-TOX and an interim analysis for futility was planned after the first 127 events. Results: At the cut-off date of interim analysis, median PFS was 6.3 months [95% confidence interval (CI) 5.0–8.1] in arm A vs 6.3 months (95% CI 5.0–7.8) in arm B, without statistical difference. OS was comparable in the two arms: 12.4 in arm A (95% CI 9.1–19.2) vs 11.5 months in arm B (95% CI 8.6–15.0). ORR was 33% and 24%, while DCR was 68% and 67%, respectively. Treatment modification (91% vs 78%, P = 0.017) and number of patients with CTC grade ≥ 3 adverse events (42 vs 35) were higher in arm B. Conclusions: A triplet regimen based on the fractional dose of docetaxel achieves no improvement over EOX which remains a potential standard treatment in many patients with inoperable, locally advanced or metastatic GC.

This study was designed to demonstrate the non-inferiority (NI) in overall survival (OS) of suspension of androgen deprivation therapy (ADT) versus maintenance and intermittent versus continuous docetaxel administration in metastatic castration-resistant prostate cancer (mCRPC) patients. mCRPC patients were randomised to first-line docetaxel with maintenance or suspension of ADT. Patients attaining a prostate-specific antigen (PSA) response after four chemotherapy cycles underwent second randomisation to receive continuous or intermittent docetaxel therapy. Six hundred patients were to be randomised to achieve 80% statistical power to demonstrate an NI hazard ratio (HR) of 1.25 of interruption versus maintenance of ADT. The trial was prematurely closed when 198 participants were randomised. OS was similar in patients who continued (N = 96) versus those who interrupted (n = 102) ADT during docetaxel therapy (HR 0.98, 95% confidence interval [CI] 0.72–1.33] and those on a continuous (N = 35) versus an intermittent (N = 42) docetaxel schedule (HR 0.86, 95% CI 0.55–1.43). No difference in radiological progression-free survival, PSA response, or toxicity was observed between the study arms. The actual NI hazard margins of OS in Arms A and B patients were 1.33 and 1.43, respectively. This trial enrolled one-third of the planned patients; this main weakness dramatically limits the interpretation of the results. ADT discontinuation and switching to an intermittent schedule did not seem to affect docetaxel efficacy. The absence of testosterone recovery in the majority of patients could have been a contributory factor. In men with mCRPC, ADT discontinuation should only be done with regular biochemical and clinical monitoring, with the option of quickly restarting ADT at disease progression. • Docetaxel efficacy in metastatic castration-resistant prostate cancer patients may be not worsened by androgen deprivation therapy (ADT) discontinuation. • Few patients discontinuing ADT achieved testosterone levels above castration. • Switching to an intermittent schedule may not affect the docetaxel toxicity. • The study was stopped prematurely due to low accrual.

Previous studies on oxaliplatin and fluoropyrimidines as adjuvant therapy in older patients with stage III colon cancer (CC) produced conflicting results. We assessed the impact of age on time to tumour recurrence (TTR), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) in 2360 patients with stage III CC (1667 aged <70 years and 693 ≥ 70 years) randomised to receive 3 or 6 months of FOLFOX or CAPOX within the frame of the phase III, TOSCA study. Older patients compared with younger ones presented more frequently an Eastern Cooperative Oncology Group performance status equal to 1 (10.5% vs 3.3%, p < 0.001), a greater number of right-sided tumours (40.9% vs 26.6%, p < 0.001), and were at higher clinical risk (37.2% vs 33.2%, p = 0.062). The treatments were almost identical in the two cohorts (p = 0.965). We found a greater proportion of dose reductions (46.7% vs 41.4%, p = 0.018), treatment interruptions (26.1% vs 19.3%, p < 0.001) and a higher proportion of recurrences (24.2% vs 20.3%, p = 0.033) in the older patients. The multivariable analysis of the TTR did not indicate a statistically significant effect of age (hazard ratio [HR]: 1.19; 95% confidence interval [CI]: 0.98–1.44; p = 0.082). The HR comparing older with younger patients was 1.34 (95% CI: 1.12–1.59; p = 0.001) for DFS, 1.58 (95% CI: 1.26–1.99; p < 0.001) for OS, and 1.28 (95% CI: 0.96–1.70; p = 0.089) for CSS. Worse prognostic factors and reduced treatment compliance have a negative impact on the efficacy of oxaliplatin-based adjuvant therapy in older patients. • The outcome of oxaliplatin as an adjuvant therapy in elderly patients with colon cancer is doubt. • Worse prognostic factors and reduced compliance have a negative impact on its effectiveness. • Fluoropyrimidine monotherapy is an appropriate choice for most elderly patients. • Only fit elderly patients should receive oxaliplatin as an adjuvant therapy.

Purpose: Chemotherapy-induced nausea and vomiting (CINV) is a common adverse event with cancer chemotherapy, despite the availability of effective antiemetic agents. This is a prospective observational study of Italian breast cancer patients treated with anthracycline plus cyclophosphamide (AC), assessed CINV incidence, adherence to national antiemetic guidelines (AIOM 2012), and the relationship with CINV outcomes.Methods: Patients with breast cancer scheduled to receive their first cycle of an AC-based regimen were enrolled at 12 Italian centers and their clinical data prospectively recorded. CINV incidence was assessed from patient diaries after the first chemotherapy cycle. The relationship between guideline adherence and CINV outcomes was examined using multiple logistic regression.Results: The overall incidence rates of nausea and vomiting among 246 evaluable patients were 63.0 and 25.4%, respectively. Most patients received a 5-HT3-RA agent and dexamethasone for acute phase CINV prophylaxis, whereas a triple combination including aprepitant (NK1-RA), consistent with national guidelines, was used in only 45.5% of cases. In the delayed phase, the guideline adherence was 48.8%, while the overall adherence was 43.5%. After adjusting for confounding factors, adherence to antiemetic prophylaxis guidelines was associated with a significant reduction in the odds of three endpoints, namely any nausea, "significant nausea," and vomiting (OR = 0.49, OR = 0.54, and OR = 0.48, respectively), and a 90% increase in the odds of overall complete protection (OR = 1.90).Conclusions: CINV is still a critical issue in AC-treated patients, despite antiemetic treatment. Non-adherence to antiemetic guidelines may lead to poorer outcomes and indicates the need for strategies to enhance the use of guidelines in clinical practice. [ABSTRACT FROM AUTHOR]

Background: Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer.Methods: FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer. Eligible patients had histologically confirmed invasive hormone receptor-positive breast cancer that had been completely removed by surgery, any pathological tumour size, and axillary nodal status. Key exclusion criteria were hormone replacement therapy, recurrent or metastatic disease, previous treatment with tamoxifen, and another malignancy in the previous 10 years. Patients were randomly assigned in an equal ratio to one of six treatment groups: oral anastrozole (1 mg per day), exemestane (25 mg per day), or letrozole (2·5 mg per day) tablets upfront for 5 years (upfront strategy) or oral tamoxifen (20 mg per day) for 2 years followed by oral administration of one of the three aromatase inhibitors for 3 years (switch strategy). Randomisation was done by a computerised minimisation procedure stratified for oestrogen receptor, progesterone receptor, and HER2 status; previous chemotherapy; and pathological nodal status. Neither the patients nor the physicians were masked to treatment allocation. The primary endpoint was disease-free survival. The minimum cutoff to declare superiority of the upfront strategy over the switch strategy was assumed to be a 2% difference in disease-free survival at 5 years. Primary efficacy analyses were done by intention to treat; safety analyses included all patients for whom at least one safety case report form had been completed. Follow-up is ongoing. This trial is registered with the European Clinical Trials Database, number 2006-004018-42, and ClinicalTrials.gov, number NCT00541086.Findings: Between March 9, 2007, and July 31, 2012, 3697 patients were enrolled into the study. After a median follow-up of 60 months (IQR 46-72), 401 disease-free survival events were reported, including 211 (11%) of 1850 patients allocated to the switch strategy and 190 (10%) of 1847 patients allocated to upfront treatment. 5-year disease-free survival was 88·5% (95% CI 86·7-90·0) with the switch strategy and 89·8% (88·2-91·2) with upfront treatment (hazard ratio 0·89, 95% CI 0·73-1·08; p=0·23). 5-year disease-free survival was 90·0% (95% CI 87·9-91·7) with anastrozole (124 events), 88·0% (85·8-89·9) with exemestane (148 events), and 89·4% (87·3 to 91·1) with letrozole (129 events; p=0·24). No unexpected serious adverse reactions or treatment-related deaths occurred. Musculoskeletal side-effects were the most frequent grade 3-4 events, reported in 130 (7%) of 1761 patients who received the switch strategy and 128 (7%) of 1766 patients who received upfront treatment. Grade 1 musculoskeletal events were more frequent with the upfront schedule than with the switch schedule (924 [52%] of 1766 patients vs 745 [42%] of 1761 patients). All other grade 3-4 adverse events occurred in less than 2% of patients in either group.Interpretation: 5 years of treatment with aromatase inhibitors was not superior to 2 years of tamoxifen followed by 3 years of aromatase inhibitors. None of the three aromatase inhibitors was superior to the others in terms of efficacy. Therefore, patient preference, tolerability, and financial constraints should be considered when deciding the optimal treatment approach in this setting.Funding: Italian Drug Agency.

Background: Different antiangiogenics are currently indicated in the second-line treatment of metastatic colorectal cancer (mCRC), following a first-line bevacizumab-containing treatment. The magnitude of benefit is limited, but no predictors of benefit have been identified.Methods: A total of 184 mCRC patients progressing to a first-line bevacizumab-containing treatment were randomised in the BEBYP study to continue or not the antiangiogenic in combination with a second-line chemotherapy. A subgroup analysis according to baseline serum lactate dehydrogenase (LDH) levels was carried out.Results: A significant interaction effect between LDH levels and treatment was found in terms of progression-free survival (PFS; P=0.002). Although patients with low LDH levels achieved significant PFS benefit from the continuation of bevacizumab (HR: 0.39 (95% CI: 0.23-0.65)), patients with high levels did not (HR: 1.10 (95% CI: 0.74-1.64)). Consistent results were reported in overall survival (OS; P=0.075).Conclusions: As preclinical evidence suggests that serum LDH may be a marker of tumour angiogenesis activation, low levels may indicate that bevacizumab is still efficacious in inhibiting angiogenesis. Validation of present results in subgroup analyses of other randomised trials of second-line angiogenesis inhibitors is warranted. [ABSTRACT FROM AUTHOR]

Background: Metronomic oral vinorelbine could be a safe option for elderly patients with advanced non small cell lung cancer (NSCLC). Metronomic administration of chemotherapy leads to a cytostatic action shifting treatment target from cancer cell to tumor angiogenesis. Methods: 43 chemotherapy naive elderly (≥70 yrs) PS 0-2 patients with stage IIIB-IV NSCLC were prospectively recruited. Median age was 80 yrs (M/F 36/7) with predominantly squamous histology. PS distribution was 0-1 (16)/2(27) with a median of 3 serious co-morbid illnesses. Study treatment consisted of oral vinorelbine 50mg three times weekly (Monday-Wednesday-Friday) continuously until disease progression, unacceptable toxicity or patient refusal. Primary endpoints were overall response rate (ORR), clinical benefit (CB - disease response plus disease stabilization >12 weeks) and safety. Health-related QoL (HRQoL) was also assessed with FACT-L V4 scoring questionnaire. We conducted an exploratory time-course analysis of VEGF and thrombospondin-1 (TSP1) serum levels in a subgroup of patients. Results: Patients received a median of 5 (range 1-21) cycles with a total of 272 cycles delivered. ORR was 18.6% with 7 partial and 1 complete responses; 17/43 experienced stable disease lasting more than 12 weeks leading to an overall CB of 58.1%. Median time to progression was 5 (range 2-21) and median overall survival 9 (range 3-29) months. Treatment was well tolerated with rare serious toxicity. Regardless of severity main toxicities observed were anemia in 44%, fatigue in 32.4%, and diarrhoea 10.5%. FACT-L v4 scores did not significantly vary during treatment. Baseline VEGF levels were lower and showed a rapid increase during treatment in non-responders pts only while TSP1 levels did not change. Conclusions: Metronomic oral vinorelbine is safe in elderly patients with advanced NSCLC with an interesting activity mainly consisting in long-term disease stabilization coupled with an optimal patient compliance (Eudra-CT 2010-018762-23, AIFA OSS on 26 February 2010).

The article presents a study that reveals the promise offered by chemotherapy with fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) plus bevacizumab in treating metastatic colorectal cancer as compared with fluorouracil, leucovorin, and irinotecan (FOLFIRI). The study involved 12 cycles of treatment followed by fluorouracil plus bevacizumab until disease progression and show improved outcome in patients with metastatic colorectal cancer in FOLFOXIRI plus bevacizumab.

Abstract: Objectives: Customized chemotherapy has several advantages: patients are more likely to be treated with the most effective agents and can be spared the toxicity of ineffective drugs. Based on the literature, excision repair cross complementation group 1 (ERCC1) and ribonucleotide reductase M1 (RRM1) genes represent predictive biomarkers of response to platinum compound and gemcitabine, in NSCLC. Materials and methods: We had planned a phase II trial (Simon design) to evaluate combination chemotherapy according to single nucleotide polymorphisms (SNPs) of ERCC1 (118T/C and 8092C/A) and RRM1 (−37C/A and −524T/C) in naïve patients affected by advanced NSCLC. ERCC1 and RRM1 SNPs assessment was performed in peripheral blood lymphocytes (PBLs). Combination chemotherapy was selected based on ERCC1 and RRM1 SNPs: we assume that patients with one or two C alleles at position 118 and with one or two A alleles at position 8092 in ERCC1 gene would correspond to Cisplatin non-responder and than with two A alleles at −37 and two C alleles at −524 in RRM1 gene to gemcitabine non-responder. Four schedules were provided: cisplatin+gemcitabine, cisplatin+docetaxel, gemcitabine+docetaxel; docetaxel+vinorelbine. Primary endpoint was overall response (ORR) in the intention-to-treat population. Results: 42 patients were enrolled from January 2010 to November 2011; 40 patients received at least 1 cycle of chemotherapy; median age was 66 years (range: 47–72); 36(90%) had stage IV, 4(10%) IIIB; 23(58%) had adenocarcinoma, 14(35%) squamous carcinoma. Twenty-five (62%) patients received treatment A, 3(8%) treatment B, 11(28%) treatment C, 1(23%) treatment D. ORR was 55%, analysis in squamous patients subgroups showed 71.4% ORR. The median follow-up was 19.7 months, PFS was 23 weeks (95% CI=15–26) and OS was 40.4 weeks (95% CI=32–55). Treatment was well tolerated. Conclusion: We observed an increase of ORR in NSCLC patients when they were treated with chemotherapy according to ERCC1 and RRM1 SNPs status. [Copyright &y& Elsevier]

Background: International treatment guidelines recommend administration of adjuvant chemotherapy in early breast cancer based on clinical, prognostic and predictive parameters. Methods: An observational study (NEMESI) was conducted in 63 Italian oncology centres in patients with early breast cancer. Age, performance status, concomitant disease, menopausal status, histology, tumor dimension (pT), axillary lymph node status (pN), grading (G), estrogen and progesterone receptor (ER and PgR), proliferative index (ki67 or MIB-1), human epidermal growth factor receptor 2 (HER2) and type of adjuvant treatment were recorded. The primary objective of the study was to define parameters influencing the decision to prescribe adjuvant chemotherapy and the type of chemotherapy. Results: Data for 1894 patients were available. 69.0% postmenopausal, 67.0% pT1, 22.3% pTmic/pT1a/pT1b, 61.0% pN0, 48.7% luminal A, 18.1% luminal B, 16.1% HER2 positive, 8.7% triple negative, 8.4% unknown. 57.8% received adjuvant chemotherapy: 38.1% of luminal A, 67.3% luminal B, 88.2% HER2-positive, 97.6% triple negative. Regimens administered: 9.1% CMF-like, 48.8% anthracyclines, 38.4% anthracyclines plus taxanes, 3.7% taxanes alone. Increasing pT/pN and, marginally, HER2-positive were associated with the prescription of anthracyclines plus taxanes. Suboptimal schedules (CMF-like or AC/EC or FEC-75) were prescribed in 37.3% receiving chemotherapy, even in HER2-positive and triple negative disease (36.5% and 34.0%, respectively). Conclusions: This study showed an overprescription of adjuvant chemotherapy for early breast cancer, particularly referred to luminal A. pT, pN and, marginally, HER2 were the principal determinants for the choice of chemotherapy type. Suboptimal chemotherapy regimens were adopted in at least one third of HER2-positve and triple negative. [ABSTRACT FROM AUTHOR]

Background: The human epidermal growth factor receptor 2 (HER2) and p53 pathways may be involved in chemotherapy sensitivity and/or resistance. We explore the value of HER2 and p53 status to foretell docetaxel sensitivity in advanced breast cancer. Methods: HER2 and p53 expression was analysed in 36 (median age 55 yrs; range 37-87) metastatic breast cancer patients receiving docetaxel-based first-line chemotherapy. HER2 was determined by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), p53 was tested by IHC. We correlate the expression of study parameters with pathologic parameters, RECIST response and survival. The standard cut-off value of 2 was used to determine HER2 overexpression while p53 mean expression level was used to divide low/high expressors tumors. Results: Median time to progression and overall survival were 9 (range 2 - 54) and 20 (range 3 - 101) months. Overall response rate was 41.6%. Nine cases showed HER2 overexpression. HER2 was more frequently overexpressed in less differentiated (p = 0.05) and higher stage (p = 0.003) disease. Mean FISH-HER2 values were significantly higher in responder than in non-responder pts (8.53 ± 10.21 vs 2.50 ± 4.12, p = 0.027). Moreover, HER2 overexpression correlates with treatment response at cross-tabulation analysis (p = 0.046). p53 expression was only associated with higher stage disease (p = 0.02) but lack of any significant association with HER status or docetaxel response. No significant relation with survival was observed for any parameter. Conclusion: Our data seem to indicate that FISH-determined HER2 status but not p53 is associated with docetaxel sensitivity in metastatic breast cancer. [ABSTRACT FROM AUTHOR]

Summary: Background: The FOLFOXIRI (irinotecan, oxaliplatin, fluorouracil, and folinate) regimen has been shown to be better than FOLFIRI (fluorouracil, folinate, and irinotecan) in a phase 3 trial in patients with metastatic colorectal cancer. Results of various studies have shown that the addition of bevacizumab to chemotherapy increases treatment efficacy. We therefore assessed the safety and activity of the combination of FOLFOXIRI plus bevacizumab in patients with colorectal cancer. Methods: In a phase 2 study, patients (aged 18–75 years) with colorectal cancer, which was judged to be unresectable for metastatic disease, were given the combination of intravenous bevacizumab (5 mg/kg on day 1) and intravenous FOLFOXIRI (irinotecan 165 mg/m2 on day 1, oxaliplatin 85 mg/m2 on day 1, folinate 200 mg/m2 on day 1, and fluorouracil 3200 mg/m2 for 48 h continuous infusion starting on day 1 and repeated every 2 weeks) as first-line treatment in seven centres in Italy. Induction treatment (FOLFOXIRI and bevacizumab) was administered for a maximum of 6 months, followed by maintenance treatment with bevacizumab (5 mg/kg intravenously on day 1, repeated every 2 weeks). The primary endpoint was progression-free survival (PFS) at 10 months from study entry in the intention-to-treat population. This study has been completed and is registered with ClinicalTrials.gov, number NCT01163396. Findings: From July 2, 2007, to April 1, 2008, 57 patients were enrolled; all patients were assessed for safety and efficacy. Median follow-up time was 28·8 months (95% CI 24·9–32·5). PFS at 10 months was 74% (95% CI 62–85). Main grade 3 or 4 adverse events during induction treatment were neutropenia (n=28 [49%], including one case of febrile neutropenia), diarrhoea (n=8 [14%]), stomatitis (n=2 [4%]), neurotoxicity (n=1 [2%]), deep-vein thrombosis (n=4 [7%]), and hypertension (n=6 [11%]). No treatment-related deaths occurred. Six serious adverse events occurred during the induction treatment: febrile neutropenia (n=1 [2%]), grade 3 diarrhoea with dehydration (n=2 [4%]), grade 4 stomatitis (n=1 [2%]), grade 4 hypertension (n=1 [2%]), and fluorouracil-related cardiac ischaemia (n=1 [2%]). The most common grade 3 or 4 adverse events noted in the 37 patients who received maintenance treatment were hypertension (n=5 [14%]) and neurotoxicity (n=3 [8%]). One case of acute myocardial infarction due to coronary thrombosis was noted during the maintenance treatment. Interpretation: Bevacizumab can be safely used with FOLFOXIRI without causing unforeseen adverse events. Treatment achieved promising results in terms of PFS. A phase 3 study for the comparison of FOLFOXIRI plus bevacizumab with FOLFIRI plus bevacizumab is in progress. Funding: Gruppo Oncologico Nord Ovest, ARCO Foundation, and Roche.

Abstract: Background: Erlotinib demonstrated significantly prolonged survival versus placebo in patients with advanced NSCLC who had progressed after standard chemotherapy. TRUST is a phase IV trial initiated to provide erlotinib access to patients with advanced NSCLC. We report the interim analysis for patients enrolled in the TRUST trial in Italy. Patients and methods: Eligible patients had stage IIIB/IV NSCLC and had failed or were unsuitable for chemotherapy. Erlotinib (150mg/day orally) was given until disease progression or unacceptable toxicity. Patients were monitored monthly. Results: At time of this analysis, data from 651 patients were available. Patient characteristics were: median age 66 years (range 30–87), male 69%, former or current smoker 71%, ECOG PS 0–1 81%, adenocarcinoma histology 52% and stage IV 82%. Erlotinib was administered as first-, second-, third- or other-line in 12, 45, 43 and <1% of patients, respectively. Response rate was 9%, with a disease-control rate of 63%. Median progression-free survival was 15 weeks and was longer in females (p <0.001), patients with adenocarcinoma (p =0.008), those with no smoking history (p <0.001) and patients who experienced skin toxicity (p <0.001). Safety data were available for 609 patients, 35% of whom had at least one adverse event (AE), but only 4% of patients discontinued treatment due to erlotinib-related AEs. Conclusion: This analysis of the Italian TRUST results confirms the activity and favourable safety profile of erlotinib in unselected patients with advanced NSCLC. [Copyright &y& Elsevier]

Studies in animals synchronized with an alternation of 12 h of light and 12 h of darkness have showed that hematological and systemic toxicities could be reduced if vinorelbine were administered 19 or 23 hours after light onset (HALO), corresponding to 17:00 and 21:00 h in diurnally active humans. This trial aimed to define the least toxic time of vinorelbine administration in metastatic breast cancer patients. Initially, the study treatment consisted of three courses of vinorelbine of 30 mg/m2/d on D1 and D6 and chronomodulated 5-fluorouracil of 850 mg/m2 from D2 to D5 every 21 days. Ninety metastatic breast cancer patients were randomized to receive vinorelbine at one of the eight possible dosing times. Further to the recommendations of the Independent Data Monitoring Committee, the vinorelbine dose was reduced to 25 mg/m2/d midway through the study. The primary objective of the study was detection of the least toxic time based on the incidence of grade 3-4 (G3-4) neutropenia. To show a significant result, the 90% confidence interval width of the least toxic time had to be<6 h. The least toxic time detection based on the incidence of other toxicities was also analyzed. The time of least drug toxic was estimated using a logistic regression model assuming that the logit transformation of the toxicity rate follows a sinusoidal distribution over 24 h. The bootstrap technique was used to obtain the 90% confidence interval. The least toxic time of G3-4 neutropenia was observed at 21:00 h with a non-significant 90% CI. Secondary endpoint analyses indicated the least toxic time could differ when based on other toxicity parameters (e.g., a significant least toxic time of 17:00 h was observed for G3-4 leucopenia), in agreement with animal data. The least toxic time of 10:30 h was estimated for any G3-4 gastrointestinal toxicity. This results of this study do not allow us to recommend an optimal time for vinorelbine administration. It has highlighted, however, the inherent methodological difficulties in the conduct of such a trial in the human setting. It indicates that future optimal time-finding trials should have tolerability and/or activity as the primary endpoint in place of a particular toxicity. The randomized optimal time-finding design may be used to identify the best time of chemotherapy administration. (Author correspondence: bcoudert@dijon.fnclcc.fr) [ABSTRACT FROM AUTHOR]

Objectives: The purpose of this study was to evaluate the clinical efficacy and tolerability of high-dose (HD) chemotherapy with growth factor support in primary breast cancer with extensive nodal involvement. Patients and Methods: Fifty-three patients with ten or more involved nodes were recruited and were given three cycles of standard-dose fluorouracil, epidoxorubicin and cyclophosphamide followed by one single course of high-dose CEP (cyclophosphamide, etoposide and cisplatin). No autologous progenitor support was used. Results: Five-year actuarial disease-free and overall survival were 40 and 60%, respectively. High-dose CEP required a median of 22 days of hospitalization and was associated with grade G3–G4 nausea and vomiting in two thirds of the cases. Hematological toxicity was comparable to that of high-dose therapies delivered with autologous progenitor support. No therapy-related mortality was observed. Conclusions: The efficacy of treatment was comparable to the best results of conventional therapy, with only a trend for improved survival. High-dose CEP was feasible with acceptable toxicity. Although this regimen does not require stem cell harvesting and storage, it requires clinical support comparable to autotransplantation procedures and side effects are not so manageable to recommend its use outside specialized units.Copyright © 2001 S.

We present a case of metastatic spreading to the testicle in a 46-year-old patient with renal cell carcinoma, ‘clear-cell’ type, during interleukin-2 combined subcutaneous plus aerosol treatment. Testicular metastasis occurred while the patient showed a response to the treatment with disappearance of lung lesions and reduction of lymph-nodes lesions. After orchiectomy with spermatic cord resection and disease re-evaluation confirming the previous response, the patient re-started immunotherapy. The contrast between systemic disease response to treatment and disease testicular progression might be explained by a relative insensitivity of the testicle to interleukin-2 immunotherapy as a result of a possible establishment of an immunosuppressive microenvironment. We believe that the rarity of this metastatic site and the intriguing possible mechanisms at its base, makes an interesting case for clinicians. [ABSTRACT FROM AUTHOR]

Background: Metronomic oral vinorelbine could be a safe option for elderly patients with advanced non small cell lung cancer (NSCLC). Metronomic administration of chemotherapy leads to a cytostatic action shifting treatment target from cancer cell to tumor angiogenesis.Methods: 43 chemotherapy naive elderly (≥ 70 yrs) PS 0-2 patients with stage IIIB-IV NSCLC were prospectively recruited. Median age was 80 yrs (M/F 36/7) with predominantly squamous histology. PS distribution was 0-1(16)/2(27) with a median of 3 serious co-morbid illnesses. Study treatment consisted of oral vinorelbine 50mg three times weekly (Monday-Wednesday-Friday) continuously until disease progression, unacceptable toxicity or patient refusal. Primary endpoints were overall response rate (ORR), clinical benefit (CB--disease response plus disease stabilization >12 weeks) and safety. Health-related QoL (HRQoL) was also assessed with FACT-L V4 scoring questionnaire. We conducted an exploratory time-course analysis of VEGF and thrombospondin-1 (TSP1) serum levels in a subgroup of patients.Results: Patients received a median of 5 (range 1-21) cycles with a total of 272 cycles delivered. ORR was 18.6% with 7 partial and 1 complete responses; 17/43 experienced stable disease lasting more than 12 weeks leading to an overall CB of 58.1%. Median time to progression was 5 (range 2-21) and median overall survival 9 (range 3-29) months. Treatment was well tolerated with rare serious toxicity. Regardless of severity main toxicities observed were anemia in 44%, fatigue in 32.4%, and diarrhoea 10.5%. FACT-L v4 scores did not significantly vary during treatment. Baseline VEGF levels were lower and showed a rapid increase during treatment in non-responders pts only while TSP1 levels did not change.Conclusions: Metronomic oral vinorelbine is safe in elderly patients with advanced NSCLC with an interesting activity mainly consisting in long-term disease stabilization coupled with an optimal patient compliance (Eudra-CT 2010-018762-23, AIFA OSS on 26 February 2010).
