Purpose: To determine the maximum tolerated doses (MTDs) and the dose-limiting toxicities of a biweekly administration of oral vinorelbine and gemcitabine in patients with advanced solid tumors. Patients and Methods: Twenty-eight patients with advanced stage solid tumors were enrolled, and 12 (42.9%) of them were chemotherapy naive. Escalating doses of vinorelbine (50–70 mg/m2 per os) and gemcitabine (800–1,000 mg/m2 as a 30-min intravenous infusion) were administered on days 1 and 15 in 4-week cycles. Results: MTDs were reached at 70 mg/m2 p.o. for vinorelbine and 900 mg/m2 for gemcitabine. Grade 4 neutropenia, febrile neutropenia, grade 4 nausea/vomiting and treatment delay due to grade 3 neutropenia were the dose-limiting events during the first cycle of chemotherapy. A total of 94 chemotherapy cycles were administered with only one episode of febrile neutropenia and no toxic deaths. Severe (grade 3–4) neutropenia occurred in 10% of cycles while non-hematological toxicity was mild with grade 2–3 asthenia occurring in 17 (18%) cycles. Objective responses were achieved in patients with prostate and non-small cell lung cancer. Conclusions: The combination of biweekly oral vinorelbine (70 mg/m2) and gemcitabine (900 mg/m2) is a well-tolerated regimen with promising results in patients with advanced solid tumors.

Abstract Purpose To evaluate the efficacy and the toxicity of front line FOLFOX4 combined with bevacizumab in patients with metastatsic CRC (mCRC). Patients and Methods Chemotherapy-naïve patients with mCRC, received bevacizumab (5 mg/kg every 2 weeks d1), oxaliplatin (85 mg/m2 on d1), leucovorin (200 mg/m2) on days 1 and 2 and 5-Fluorouracil (400 mg/m2 as i.v. bolus and 600 mg/m2 as 22 h i.v. continuous infusion on days 1 and 2) every 2 weeks. Results Fifty three patients (46 with a PS 0–1) were enrolled. Complete and partial response was achieved in eight (15.1%) and 28 (52.8%) patients, respectively (ORR: 67.9%; 95% C.I.: 53.8%–92%); 11 (20.7%) patients had stable disease and six (11.3%) progressive disease. With a median follow up period of 13.5 months, time to tumor progression was 11 months while the median survival has not yet been reached; the probability of 1-, 2- and 3- year survival was 79.8%, 63.8% and 58.3%, respectively; Two patients relapsed during the follow up period. Eight (15%) patients underwent metastasectomy with R0 resections. Grade 3–4 neutropenia occurred in 15.1% of patients and one (1.9%) of them presented febrile neutropenia. Non-hematologic toxicity included grade 3 diarrhea (7.6%) and grade 2 and 3 neurotoxicity in 16.9 and 15.1% of patients, respectively. One (1.9%) patient presented pulmonary embolism and one (1.9%) cardiac ischaemia. There was one (1.9%) sudden death after the first cycle. Conclusion The combination of FOLFOX4/bevacizumab appears to be highly effective, well tolerated and merits further evaluation in patients with mCRC.

Abstract: Purpose: The combination of irinotecan and cisplatin (IP) has shown at least comparable efficacy to that of etoposide/cisplatin (EP) in patients with extensive-stage small cell lung cancer. We conducted a phase II study to evaluate the efficacy and tolerance of EP regimen followed by thoracic radiotherapy (TRT) and IP consolidation chemotherapy in patients with limited-stage small cell lung cancer. Patients and methods: Thirty-three chemotherapy-naive patients with limited-stage small cell lung cancer (LS-SCLC) were treated with etoposide 100mg/m2 on days 1–3 and cisplatin 80mg/m2 on day 1. Radiotherapy was given 3 weeks after the first treatment cycle concurrently with weekly cisplatin 20mg/m2 on day 1 and etoposide 50mg/m2 on day 4 within 5–6 weeks, followed by three courses of irinotecan 60mg/m2 on days 1, 8, and 15 and cisplatin 60mg/m2 on day 1 of a 4-week cycle. Results: There were no treatment-related deaths. Toxicities during chemo-radiotherapy were mild including grade 3/4 neutropenia (24%) and grade 2 esophagitis (6%). The major toxicity observed during consolidation chemotherapy was grades 3–4 neutropenia which affected 42% of patients. In an intention-to-treat analysis the overall response rate was 66% (CR: 30% and PR: 36%). After a median follow-up period of 35.7 months (range: 9.6–41.2 months), the median survival time was 19 months (95% CI: 14.5–23.5 months), the median time to tumor progression 8.3 months and the 1- and 2-year survival rates 72% and 27.5%, respectively. Conclusions: Consolidation chemotherapy with IP following concurrent EP plus TRT is a safe and with acceptable toxicity regimen and deserves further phase III testing in patients with LS-SCLC.

Summary: Background: The docetaxel/gemcitabine (DG) combination is an active and well-tolerated regimen against non-small cell lung cancer (NSCLC). A phase II study was conducted in order to evaluate its efficacy in elderly patients with lung adenocarcinomas. Methods: Chemotherapy-naive patients, aged ≥70 years, with locally advanced or metastatic lung adenocarcinomas and performance status (PS) ≤2 (ECOG) received gemcitabine 1100mg/m2 (days 1+8) and docetaxel 100mg/m2 (day 8) with rhG-CSF support. Results: Seventy-seven patients were enrolled. One (1.3%) complete and 23 (29.9%) partial responses were achieved (intention to treat analysis: ORR 31.2%; 95% CI 20.82–41.51%) whereas tumor growth control was achieved in 53.3% of patients. The median TTP was 4.1 months, the median overall survival 9.4 months and the 1- and 2-year survival rate 37.9% and 10.7%, respectively. Grade 3–4 neutropenia occurred in 18.2% and febrile neutropenia in 3 (3.9%) patients. Non-haematological toxicity was mild with grade 2–3 asthenia occurring in 22.1% patients. Conclusions: The DG regimen is an active and well-tolerated front-line chemotherapy for elderly patients with lung adenocarcinomas and merits further evaluation in prospective randomized trials.

Summary: Purpose: To evaluate the activity and toxicity of the sequential administration of docetaxel followed by gefitinib in patients with advanced non-small cell lung cancer (NSCLC). Patients and treatment: Forty-one patients pre-treated with at least one prior chemotherapy regimen (platinum- or taxane-based) for advanced/metastatic NSCLC received three cycles of docetaxel 30mg/m2, administered as a 1-h IV infusion, on days 1, 8 and 15 of each 4-week cycle followed by gefitinib 250mg daily po. Gefitinib treatment was continued until disease progression, development of unacceptable toxicity, or withdrawal of patients consent. Results: Two (4.9%) patients achieved a partial response and 10 (24.4%) stable disease, for a disease control rate of 29.3% (95% CI: 15.3%–43.2%) while on weekly docetaxel treatment. Additionally, progressive disease (PD) was observed in 29 (70.7%). No objective responses were observed during the gefitinib maintenance therapy; however, 17 (41.5%) patients presented stable disease maintained for more than 2 months. Median time to progression was 3.0 months (range: 1–38.3 months; 95% CI: 2.4–3.6); median overall survival 6.9 months (range: 1.2–40.2 months; 95% CI: 5.34–8.52) while the 1-year survival was 28.8%. Therapy was generally well tolerated with diarrhea and rash being the most frequent toxicities. Conclusions: The sequential administration of docetaxel and gefitinib was well tolerated and moderately active against advanced pre-treated NSCLC. [Copyright &y& Elsevier]

(1) Background: There is evidence in the recent literature that the incidence patterns of colorectal cancer (CRC) have changed considerably over the years, tending to rise rapidly in individuals under 50 years old compared with those over 50 years. The current study aimed to assess the incidence of CRC in Crete from 1992−2021 and compare them among younger and older adults. (2) Methods: Data on malignant neoplasms of colon, rectosigmoid junction, and rectum have been extracted from the database of the Regional Cancer Registry of Crete. (3) Results: The number of these cases for the period 1992−2021 was 3857 (n = 2895 colon and n = 962 rectum). The mean age-specific incidence rate (ASpIR/100,000/year) of colon cancer patients <50 years was 7.2 (95% CI 5.1−9.7), while for patients ≥50 years the ASpIR was 149 (95% CI 146.2−153.4). ASpIR presented a 29.6% increase from 2001 to 2011 in the age group of 20−34 years and further increase is expected from 2022−2030 (projected change, 42.8%). The main risk factors were the pack years (p = 0.01), alcohol consumption (0.02), and farmer occupation (0.04), especially during 2012−2021. (4) Conclusions: We confirmed an increased incidence of CRC in young adults <50 in a European population with low cancer incidence in the past and a worrisome prediction for the near future. The observed trends clearly indicate that starting CRC screening at an earlier age may be essential.

Liver cancer is one of the most frequent cancers in Europe and Greece. An increase in specific risk factors, such as metabolic syndrome and obesity, has been observed in Greece. Therefore, exploring temporal trends of liver cancer incidence and mortality is crucial. This study aims to assess the "burden" of malignant liver tumors (MLT) in Crete, Greece, in terms of incidence and mortality rates, and identify the high-risk areas on the island (i.e., municipalities), to suggest public health measures. Data were obtained from the Cancer Registry Center (CRC) and included all cases of MLT for the period 1992-2013 in Crete. Age-standardized incidence rates (ASIR), age-specific incidence rates (ASpIR), age-standardized mortality rates (ASMR), and age-specific mortality rates (ASpMR) were estimated. For the study period (1992-2013), incidence and mortality showed an increasing trend. Mean ASIR was found 15.3/100,000/year and mean ASMR 8.6/100,000/year. Age groups 65-69 and 75-79 years among men presented the highest rates of (ASIR = 39/100,000/year) and among women age groups of 75-79 and 80-84 years a mean ASIR (22/100,000/year). The five-year survival rate of MLT was 50% and the ten-year survival rate was 47% for both genders. Risk factors that were identified included personal history of cancer, family history of MLT or other cancer, degree of relationship, smoking, and obesity. Some municipalities of Crete were found to be high-risk areas for MLT, while differences were detected in incidence and mortality rates, and annual rate change among them. Estimated variation indicates further increase probably due to the lifestyle of the residents, economic crisis, and inadequate preventive measures.

Background: Cancer cachexia syndrome (CCS) is an adverse prognostic factor in cancer patients undergoing chemotherapy or surgical procedures. We performed a prospective study to investigate the effect of CCS on treatment outcomes in patients with non-oncogene driven metastatic non-small cell lung cancer (NSCLC) undergoing therapy with programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors., Methods: Patients were categorized as having cancer cachexia if they had weight loss >5% in the last 6 months prior to immunotherapy (I-O) initiation or any degree of weight loss >2% and body mass index (BMI) <20 kg/m 2 or skeletal muscle index at the level of third lumbar vertebra (LSMI) <55 cm 2 /m 2 for males and <39 cm 2 /m 2 for females. LSMI was calculated using computed tomography (CT) scans of the abdomen at the beginning of I-O and every 3 months thereafter., Results: Eighty-three patients were included in the analysis and the prevalence of cancer cachexia at the beginning of I-O was 51.8%. The presence of CCS was associated with inferior response rates to ICIs (P≤0.001) and consisted an independent predictor of increased probability for developing disease progression as best response to treatment, OR =8.11 (95% CI: 2.95-22.40, P≤0.001). In the multivariate analysis, the presence of baseline cancer cachexia consisted an independent predictor for inferior survival, HR =2.52 (95% CI: 1.40-2.55, P=0.002). Reduction of LSMI >5% during treatment did not affect overall survival (OS; P=0.40)., Conclusions: CCS is associated with reduced PD-1/PD-L1 inhibitor efficacy in NSCLC patients and should constitute an additional stratification factor in future I-O clinical trials. Further research at a translational and molecular level is required to decipher the mechanisms of interrelation of metabolic deregulation and suppression of antitumor immunity., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/tlcr-21-460).

Objective: We prospectively recorded clinical and laboratory parameters from patients with metastatic non-small cell lung cancer (NSCLC) treated with 2nd line PD-1/PD-L1 inhibitors in order to address their effect on treatment outcomes., Materials and Methods: Clinicopathological information (age, performance status, smoking, body mass index, histology, organs with metastases), use and duration of proton pump inhibitors, steroids and antibiotics (ATB) and laboratory values [neutrophil/lymphocyte ratio, LDH, albumin] were prospectively collected. Steroid administration was defined as the use of > 10 mg prednisone equivalent for ≥ 10 days. Prolonged ATB administration was defined as ATB ≥ 14 days 30 days before or within the first 3 months of treatment. JADBio, a machine learning pipeline was applied for further multivariate analysis., Results: Data from 66 pts with non-oncogenic driven metastatic NSCLC were analyzed; 15.2% experienced partial response (PR), 34.8% stable disease (SD) and 50% progressive disease (PD). Median overall survival (OS) was 6.77 months. ATB administration did not affect patient OS [HR = 1.35 (CI: 0.761-2.406, p = 0.304)], however, prolonged ATBs [HR = 2.95 (CI: 1.62-5.36, p = 0.0001)] and the presence of bone metastases [HR = 1.89 (CI: 1.02-3.51, p = 0.049)] independently predicted for shorter survival. Prolonged ATB administration, bone metastases, liver metastases and BMI < 25 kg/m2 were selected by JADbio as the important features that were associated with increased probability of developing disease progression as response to treatment. The resulting algorithm that was created was able to predict the probability of disease stabilization (PR or SD) in a single individual with an AUC = 0.806 [95% CI:0.714-0.889]., Conclusions: Our results demonstrate an adverse effect of prolonged ATBs on response and survival and underscore their importance along with the presence of bone metastases, liver metastases and low BMI in the individual prediction of outcomes in patients treated with immunotherapy., Competing Interests: The authors have declared that no competing interests exist.

MicroRNAs (miRNAs) are involved in the regulation of immune response and hold an important role in tumor immune escape. We investigated the differential expression of the immunomodulatory miR-10b, miR-19a, miR-20a, miR-126, and miR-155 in the plasma of healthy women and patients with early stage breast cancer and interrogated their role in the prediction of patients' relapse. Blood samples were obtained from healthy women ( n = 20) and patients with early stage breast cancer ( n = 140) before adjuvant chemotherapy. Plasma miRNA expression levels were assessed by RT-qPCR. Relapse predicting models were developed using binary logistic regression and receiver operating curves (ROC) were constructed to determine miRNA sensitivity and specificity. Only miR-155 expression was lower in patients compared with healthy women ( p = 0.023), whereas miR-155 and miR-10b were lower in patients who relapsed compared with healthy women ( p = 0.039 and p = 0.002, respectively). MiR-155 expression combined with axillary lymph node infiltration and tumor grade demonstrated increased capability in distinguishing relapsed from non-relapsed patients [(area under the curve, (AUC = 0.861; p < 0.001)]. Combined miR-19a and miR-20a expression had the highest performance in discriminating patients with early relapse (AUC = 0.816; p < 0.001). Finally, miR-10b in combination with lymph node status and grade had the highest accuracy to discriminate patients with late relapse (AUC = 0.971; p < 0.001). The robustness of the relapse predicting models was further confirmed in a 10-fold cross validation. Deregulation of circulating miRNAs involved in tumor-immune interactions may predict relapse in early stage breast cancer. Their successful clinical integration could potentially address the significance challenge of treatment escalation or de-escalation according to the risk of recurrence.

Germline BRCA1 and BRCA2 loss-of-function variants have been linked to increased breast and ovarian cancer risk, with more than 5,000 distinct pathogenic variants being reported worldwide. Among individuals of Greek descent, the BRCA1/2 variant spectrum is heterogeneous, but characterized by strong founder effects. As patients from certain geographical regions of Greece (like Crete) were underrepresented in previous studies, we hypothesized that isolated Cretans, a southern Greece islanders' population with distinct demographic, cultural and genetic features, could harbor founder BRCA1/2 mutations. A total of 304 breast or/and ovarian cancer patients of Cretan descent, fulfilling NCCN criteria for genetic testing, were tested by NGS or Sanger sequencing, followed by MLPA. Haplotype analysis was subsequently performed to investigate potential founder effects of recurrent alleles. Overall, 16.5% (50/304) of the tested patients carried 22 different pathogenic variants; 48% in BRCA1, 52% in BRCA2. Three variants, namely two in BRCA2 (Δexons 12 and 13 and c.7806-2A>T) and one in BRCA1 (c.5492del), constituting approximately half (48%) of all detected pathogenic variants, were shown to have a founder effect, with all carriers sharing common haplotypes. Remarkably, these variants were confined to Cretans and have not been identified in other regions of Greece. The high prevalence of specific BRCA1/2 pathogenic variants among Cretans, provides the possibility of cost- and time-efficient screening of the Cretan population. Integrating this knowledge in local public health services may have a significant impact on cancer prevention, and may serve as a starting point for the implementation of testing on a population level., (© 2020 UICC.)

Background: Although colorectal cancer (CRC) is a disease of the older patients, older patients are under-represented from randomized trials. Herein we conducted a retrospective analysis for the effect of panitumumab in the management of older patients (≥65 years) patients with metastatic CRC (mCRC) in the Hellenic Oncology Research Group's (HORG) database., Methods: Τhe efficacy of panitumumab-based chemotherapy as front-line treatment in older patients with mCRC was assessed., Results: In total, 110 older patients with KRAS exon 2 wild type tumors were treated with chemotherapy plus panitumumab. The median age was 74 years; 69.9% of the patients were male, with left-sided primary tumors (78.2%), ECOG Performance Status 0-1 (95.4%) and median number of metastatic sites 2. Sixty-two (Overall Response Rate-ORR: 56.4%; 95% CI: 48.8%-68.1%) achieved an objective response, while 21 (19.1%) had stable disease. Median Progression free survival (PFS) was 9.4 months (95% CI: 7.8-11.0 months) and median Overall survival (OS) 23.0 months (95% CI: 20.6-25.3 months). Additionally, a statistically significant difference in ORR (62.7% vs. 33.3%; p = .014), median PFS (12.9 vs. 5.7 months; p = .001) and median OS (31.6 vs. 16.7 months; p < .001) was observed in patients with left-sided compared to right-sided primary tumor. There was no treatment-related death. Grade 3-4 toxicities were neutropenia (8.9%) and diarrhea (14.5%) whereas skin rash grade 2 or 3 was recorded in 41.1% and 10.7%, respectively., Conclusions: The results of this retrospective study provide the evidence that combination chemotherapy plus panitumumab is active and well tolerated in older patients with mCRC., (Copyright © 2018 Elsevier Inc.

Background: Triple-negative breast cancer (TNBC) lacks a standard targeted therapeutic strategy and is treated with conventional cytotoxic agents. Because of the sensitivity of TNBC to platinum compounds and the synergistic effect of bevacizumab with paclitaxel we investigated the efficacy and toxicity of weekly paclitaxel and carboplatin in combination with bevacizumab as first-line treatment in metastatic TNBC., Patients and Methods: This phase II study followed the Simon's 2-stage optimal design. Paclitaxel (90 mg/m 2 ) and carboplatin (2 area under the curve) were administered on days 1, 8, and 15 every 4 weeks, preceded by bevacizumab 10 mg/kg on days 1 and 15. The primary end point was the objective response rate (ORR). The null hypothesis that the ORR is ≤ 40% could be rejected if the number of objective responses was ≥ 23 among 46 evaluable patients., Results: A total of 46 patients were enrolled. Seven (15.2%) complete and 23 (50%) partial responses were observed for an ORR of 65.2% (95% confidence interval, 52.9%-80.4%). The median progression-free survival was 10.3 months, the median overall survival 25.7 months, and the median duration of response 18.2 months. Neutropenia Grade III and IV was experienced by 13 (28.3%) and 6 (13.04%) patients, respectively. One patient developed an uneventful Grade IV thrombocytopenia. There was 1 toxic death due to febrile neutropenia. Other Grade III toxicities included anemia (n = 2), neurotoxicity (n = 2), thrombocytopenia (n = 1), and diarrhea (n = 1). No serious bevacizumab-related toxicities were observed., Conclusion: The study achieved its primary end point by showing clinical activity for weekly paclitaxel with carboplatin and bevacizumab combination. This regimen merits further evaluation in this setting., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: This study evaluated the safety and efficacy of nab-paclitaxel as second-line treatment in patients with advanced gastric adenocarcinoma., Methods: Thirty-nine pretreated patients [33 with taxane-based regimens (docetaxel, cisplatin, and fluorouracil)] and 6 with combination of fluoropyrimidines plus cisplatin with locally advanced inoperable and metastatic gastric and gastroesophageal junction adenocarcinoma were treated with weekly nab-paclitaxel (150 mg/m 2 d1, d8, d15 in cycles of 28 days)., Results: Partial response (PR) was documented in nine patients (23.1%; 95% confidence interval 10.1-37.2%), stable disease (SD) in 11 (28.2%) and disease progression in 18 (46.2%). The disease control rate (SD + PR + complete response) was 51.3%. Grade 3 and 4 neutropenia occurred in 10.2% and 5.1% of patients, respectively; grade 3 anemia in 5.1%; grade 3 neurotoxicity in 5.1%; and grade 2 pain in 5.1%. The median progression-free survival was 3.0 months (range 0.3-13.6) and the median overall survival 6.8 months (range 0.3-22)., Conclusion: Nab-paclitaxel as second-line treatment in locally advanced inoperable or metastatic gastric and gastroesophageal junction carcinoma is an active chemotherapy regimen with a manageable toxicity profile and merits further evaluation., Competing Interests: Conflict of Interest: None

Background: Platinum-based chemotherapy is the standard front-line treatment for patients with advanced non-small cell lung cancer (NSCLC). However, non-platinum combinations of third-generation chemotherapeutic agents are considered an alternative therapeutic option for patients who cannot tolerate the toxic effects of platinum compounds. In this study, the efficacy and toxicity of the combination of irinotecan plus cisplatin (IC) was compared to pemetrexed plus cisplatin (PC) regimen, in platinum-naïve patients with advanced NSCLC, who had been previously treated with the combination of a taxane plus gemcitabine., Patients and Methods: A total of 124 patients with locally advanced or metastatic NSCLC were randomly assigned to either irinotecan 110 mg/m 2 on day 1 and 100 mg/m 2 on day 8 plus cisplatin 80 mg/m 2 on day 8 every 3 weeks (IC arm) or pemetrexed 500 mg/m 2 plus cisplatin 80 mg/m 2 on day 1 every 3 weeks (PC arm). The primary endpoint of the study was the overall response rate (ORR)., Results: The ORR and median progression-free survival (PFS) in the IC arm were 18 % and 3.3 months, respectively, while in the PC arm were 19 % and 4.2 months (p = ns). Median overall survival (OS) was significantly higher in patients with PC (6.9 vs. 10.9; p = 0.013). PC regimen had a better toxicity profile compared to IC, with a statistically significant lower incidence of grade 3/4 neutropenia (3 vs. 31 %; p = 0.0001) and diarrhea (1.6 vs. 14.7 %, p = 0.018)., Conclusions: In patients with advanced NSCLC pretreated with docetaxel/gemcitabine, the combination of pemetrexed/cisplatin is associated with increased OS and is better tolerated than the combination of irinotecan/cisplatin and should be considered as a valid therapeutic option for platinum-naive, previously treated patients.

Objectives: To compare first-line treatment with docetaxel plus gemcitabine (DG) versus gemcitabine (G) in elderly patients with advanced/metastatic non-small-cell lung cancer (NSCLC)., Patients and Methods: Chemotherapy-naïve patients with inoperable stage IIIB/IV NSCLC, ≥70years, with an ECOG performance status (PS) of 0-2 were enrolled. Patients were stratified by PS and disease stage and randomized to either DG (docetaxel 30mg/m 2 plus gemcitabine 900mg/m 2 i.v.) or G (gemcitabine 1200mg/m 2 i.v.) on days 1 and 8, every 3weeks. The study's primary end-point was overall survival (OS)., Results: In this prematurely closed study, 106 patients with a median age of 75years (range, 70-92) were enrolled (DG: n=54; G: n=52); 77 (73%) had stage IV disease and 18 (17%) a PS of 2. There was no difference in terms of median OS (14.6 vs 12.2months; p=0.121), progression-free survival (PFS) (3.4 vs 2.6months; p=0.757) and overall response rate (26.0% vs 15.4%; p=0.233) between DG and G arm, respectively. Patients with an Instrumental Activities of Daily Living (IADL) score<7 had significantly lower median OS (7.6 vs 15.4months; p=0.002) and median PFS (1.7 vs 4.4months; p=0.009) than patients with higher IADL score. The regimens were well tolerated with no significant difference in severe toxicity., Conclusion: DG and G demonstrated comparable efficacy in elderly patients with NSCLC and high IADL score was correlated with superior clinical outcome., (Copyright © 2016 Elsevier Inc.

Background: The present study was a phase I/II study to determine the maximum tolerated doses (MTDs) and dose-limiting toxicities of the biweekly carboplatin/gemcitabine combination and evaluate its safety and efficacy in patients aged ≥ 70 years with advanced squamous non-small-cell lung cancer (NSCLC)., Patients and Methods: Patients aged ≥ 70 years with advanced or metastatic squamous NSCLC received escalated doses of carboplatin (area under the curve [AUC] 2-2.5 intravenously) and gemcitabine (800-1100 mg/m 2 intravenously) every 2 weeks (phase I). In the phase II, the drugs were administered at their previously defined MTDs (carboplatin, AUC 2.5; gemcitabine, 1100 mg/m 2 ). The primary endpoint was the overall response rate., Results: A total of 69 patients were enrolled (phase I, n = 15). The median age was 76 years (range, 70-84 years); 52 patients had stage IV disease, and 61 and 8 patients had Eastern Cooperative Oncology Group performance status of 0 to 1 and 2, respectively. The MTDs could not be reached at the predefined last dose levels. The dose-limiting toxicities were grade 5 renal toxicity and grade 3 thrombocytopenia. In the phase II study, the overall response rate was 35.8% (95% confidence interval [CI], 23.0%-48.8%). In the intention-to-treat analysis, the median progression-free survival was 6.7 months (95% CI, 4.2-8.8 months), and the median overall survival was 13.3 months (95% CI, 7.1-19.6 months). Grade 3 or 4 neutropenia was observed in 7 patients (12.3%), grade 3 or 4 thrombocytopenia in 4 patients (7.1%), and grade 2 or 3 fatigue in 10 patients (17.5%). One toxic death occurred in the phase I of the study., Conclusion: The biweekly regimen of gemcitabine and carboplatin showed satisfactory efficacy and a favorable toxicity profile in elderly patients with advanced or metastatic squamous cell NSCLC., (Copyright © 2016 Elsevier Inc.

Background: Bortezomib is a selective reversible proteasome inhibitor with proapoptotic effects. Preclinical and phase I clinical data suggest activity of bortezomib in NSCLC, either as monotherapy or in combination with chemotherapeutic agents including gemcitabine and cisplatin., Methods: Chemotherapy-naïve patients with inoperable stage IIIB or IV NSCLC were administered bortezomib 1 mg/m(2) i.v. on days 1 and 8, and starting on day 21 (cycle 2), bortezomib (days 1 and 8) in combination with gemcitabine 1000 mg/m(2), (days 1 and 8), and cisplatin 70 mg/m(2) (day 1) in cycles of 21 days. Up to 8 cycles of combination therapy could be administered; single-agent bortezomib was continued until disease progression or unacceptable toxicity., Results: Fifty-three patients [median age 66 years; 79.2 % male; 96.2 % stage IV; performance status (ECOG) 0/1 73.6/26.4 %; adenocarcinoma 45.3 %, squamous cell carcinoma 41.5 %] were enrolled. All patients were evaluable for toxicity and 43 for efficacy. Grade 3-4 hematologic toxicity consisted of neutropenia (22.6 %) and thrombocytopenia (17 %). Grade 2-4 non-hematologic adverse events were fever (9.4 %), fatigue (20.8 %), infection (18.9 %), and dyspnea (15.1 %). There was no >grade 2 neurotoxicity. Febrile neutropenia occurred in two (1.9 %) patients, and there were three possibly treatment-related deaths (5.4 %). In the intention-to-treat population, the objective response rate was 17 % (95 % CI 6.9-27.1 %). No difference in response rate was observed for squamous versus other histology (18.2 vs. 16.1 %, p = 0.845). The median progression-free survival was 2.5 months, the median overall survival 10.6 months and the 1-year survival rate 38.1 %., Conclusion: The incorporation of bortezomib into the gemcitabine/cisplatin regimen, in the dose and schedule used in this study, could not improve the efficacy of the chemotherapy regimen and has not to be further investigated.

Purpose: To evaluate the safety and efficacy of metronomic vinorelbine in combination with cisplatin as first-line treatment in patients with advanced non-small cell lung cancer (NSCLC)., Patients and Methods: A total of 41 patients with inoperable stage IIIb or stage IV NSCLC (14 with adenocarcinomas, 19 with squamous cell carcinoma and eight with other types), PS = 0-2, were treated with cisplatin (80 mg/m(2)) in combination with oral metronomic vinorelbine (60 mg total dose, every other day) in cycles of 21 days., Results: A total of 35 patients who received at least one cycle of chemotherapy were evaluable for toxicity and response. Partial response was achieved in 13 patients (ORR 37.1%; CI 21.1-53.1%) and stable disease in 10 (28.6%). After a median follow-up period of 26.2 months (range 0.5-33.4 months), the median progression-free survival was 4.2 months and the median overall survival 12.0 months. The 1-year survival rate was 52.6%. Myelosuppression was the main adverse event with grade 3 and 4 neutropenia occurring in five (14.3%) and six (17.1%) patients, respectively. Three of these patients presented with febrile neutropenia and there was one death due to sepsis. Non-hematologic toxicities were mild., Conclusion: Cisplatin in combination with metronomic vinorelbine is an active, although myelotoxic, therapeutic option in the first-line setting for the treatment of patients with locally advanced and metastatic non-small cell lung cancer, which merits further evaluation in randomized trials.

Purpose: To evaluate the activity and safety of the docetaxel, gemcitabine and bevacizumab combination, administered biweekly, in pretreated patients with HER-2-negative metastatic breast cancer (MBC)., Patients and Methods: Women with HER-2-negative MBC, and disease progression after at least one prior line of chemotherapy, were treated with docetaxel 50 mg/m², gemcitabine 1,500 mg/m² and bevacizumab 10 mg/kg every 2 weeks. Bevacizumab was continued until disease progression., Results: Forty-eight patients have been enrolled. Their median age was 61 years, 95.8 % had a performance status 0-1, 83.3 % had hormone receptor-positive disease, and 47.9 % had received one prior line of chemotherapy. All patients were evaluable for toxicity and 45 for response. Partial response was achieved in 20 patients [PR = 44.4 %, 95 % confidence interval (CI) 29.9-59 %] and disease stabilization in 15 (33.3 %). The median progression-free survival was 7.1 months (95 % CI 4.7-9.5 months) and the median overall survival 21.1 months (95 % CI 10.3-31.9 months). Grade 3-4 neutropenia occurred in 19 patients (39.6 %) and febrile neutropenia in 2 (4.2 %). Most common grade 2-3 non-hematologic adverse events included nausea (10.4 %), diarrhea (10.5 %), neurotoxicity (12.5 %) and fatigue (31.3 %), whereas grade 2 hemorrhage and hypertension occurred in 6.3 and 10.4 %, respectively. There were no grade 4 non-hematologic toxicities or toxic deaths., Conclusion: The combination of docetaxel, gemcitabine and bevacizumab has promising activity and manageable toxicity as salvage chemotherapy for HER-2-negative MBC patients.

Metastatic pancreatic adenocarcinoma confers a poor prognosis. Even with recent advances in the treatment of this disease with the introduction of two modestly effective chemotherapy regimens, complete responses are still very rare. Moreover, there are no published data on how to further manage the patients who achieve a sustained remission following treatment. Herein, we report the case of a patient with metastatic pancreatic adenocarcinoma who achieved a complete response lasting for more than three years after receiving induction chemotherapy with FOLFIRINOX followed by maintenance with FOLFIRI.

Background: Colorectal cancer (CRC) is a disease of the elderly. However, geriatric patients are often excluded from clinical trials. The combination of capecitabine, oxaliplatin and bevacizumab (XELOX/BEV) has not been assessed in an elderly population., Methods: We conducted a phase II study of XELOX plus bevacizumab combination as first line treatment in elderly patients with metastatic CRC. Treatment consisted of capecitabine 750 mg/m2 twice a day during days 1-7, oxaliplatin 85 mg/m2 and bevacizumab 5 mg/kg on day 1. Treatment was repeated every 14 days. The primary endpoint was overall response rate., Results: In the 48 enrolled patients response rate according was 46.8% (95% CI: 32.54%-61.07%), while 13 patients had stable disease, for an overall disease control rate of 74.4% (95% CI: 57.8-91.2). Progression free survival was 7.9 months (95% CI: 5.9-9.8 months) and the median overall survival 20.1 months (95% CI: 15.6-25.7 months). Response rate and progression free survival has been correlated with baseline albumin and haemoglobin levels. There was one treatment-related death. Grade 3-4 toxicities were asthenia (4.2%), neurotoxicity (2.1%) and diarrhea 6.3%)., Conclusions: The combination of capecitabine, oxaliplatin and bevacizumab is an effective and safe combination for the treatment of elderly patients with metastatic CRC., Trial Registration: Clinical trials NCT01024504, 26 November 2010.

Background: We conducted a multicenter prospective trial to assess tolerability and activity of pegylated liposomal doxorubicin (PLD) in women ≥ 70 years with locally-advanced or metastatic breast cancer., Patients and Methods: All patients underwent Multidimensional Geriatric Assessment (MGA). Frail patients were excluded. Normal cardiac function was required for inclusion. A bi-weekly schedule of PLD at 20mg/mq was adopted., Results: Thirty-two patients were enrolled with a median age of 78 years, 78.1% with visceral involvement, and 37.6% previously treated with chemotherapy for advanced disease. A mean of 7.8 cycles were delivered (range 1 to 20), with a median cumulative dose intensity of 8.9 mg/m(2)/week. Grade 3-4 toxicities were anemia (6.3%), palmar-plantar erythrodysesthesia (6.3%), mucositis (6.3%), infection (3.1%), and pulmonary embolism (3.1%). No cardiac events were registered. Causes of treatment interruption were maximal response (15.6%), progression (40.6%), refusal/loss to follow-up (28.1%), toxicities (9.4%), or other (6.3%). Response was obtained in 33.3% of 27 evaluable patients; median time to progression (TTP) was 10.3 months. MGA status (vulnerable vs. fit) did not have an impact on response, progression, and toxicity., Conclusions: Bi-weekly PLD is well tolerated in both fit and vulnerable patients, with an apparently fairly good response rate and TTP (possibly biased by subsequent endocrine therapy and loss to follow-up). Close observation of patients is recommended in order to avoid early refusal/loss to follow-up., (© 2013.)

Background: In this superiority study, pemetrexed was compared with erlotinib in pre-treated patients with metastatic non-small cell lung cancer (NSCLC)., Methods: Patients with stage IIIB/IV NSCLC who progressed after first-line or second-line treatment were randomized to receive either pemetrexed or erlotinib. In total, 21.7% of patients in the pemetrexed arm and 23.5% of patients in the erlotinib arm had squamous cell histology, and treatment was third line in 39.2% and 46.4% of patients, respectively. The primary study endpoint was time to tumor progression (TTP). Epidermal growth factor receptor/v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (EGFR/KRAS) mutation status also was investigated., Results: There was no difference in terms of the TTP (P = .195), the objective response rate (P = .469), or overall survival (P = .986) between the 2 treatment arms. In patients who had squamous cell histology, erlotinib resulted in a superior TTP compared with pemetrexed (4.1 months vs 2.5 months, respectively; P = .006). The incidence of grade 3 and 4 neutropenia, thrombocytopenia, and asthenia was significantly higher in the pemetrexed arm, whereas the incidence of grade 3 and 4 skin rash was higher in the erlotinib arm., Conclusions: Both pemetrexed and erlotinib had comparable efficacy in pre-treated patients with metastatic NSCLC, and the current results indicated that genotyping of tumor cells may have an important effect on treatment efficacy., (© 2013 American Cancer Society.)

Background: The docetaxel/cisplatin (DC) combination is an active regimen against advanced/metastatic non-small-cell lung cancer (NSCLC), and bevacizumab (B) improves the efficacy of frontline chemotherapy. This phase II study was designed in order to explore the efficacy and safety of DCB regiment in this setting., Methods: Chemotherapy-naïve patients (n = 48) with measurable, histologically confirmed non-squamous, IIIB (wet)/IV NSCLC, and PS 0-2 were eligible. Patients received D (75 mg/m(2) IV), C (80 mg/m(2) IV), and B (15 mg/kg IV) every 3 weeks. Maintenance of bevacizumab was not mandatory., Results: Complete and partial responses were achieved in two (4.2%) and 14 (29.2%) patients, respectively [overall response rate: 33.3%; 95% CI = 20.0-46.7%], whereas stable disease was documented in 14 [disease control rate = 62.5%; 95% CI = 48.8-76.2%]. The median progression-free survival was 4.4 months and the median overall survival 13.3 months. Treatment-related grade 3 or 4 hematologic adverse events were leukopenia, neutropenia, and anemia in 8.4, 18.7, and 2.1% of the patients, respectively. Febrile neutropenia occurred in three (6.3%) patients. Bleeding was documented in 4% of the patients, thrombotic episodes in 8%, and proteinuria in 3%. There was one treatment-related death., Conclusions: Frontline DCB in patients with advanced non-squamous NSCLC is an active regimen with manageable toxicity and merits to be further investigated.

A 70-year-old man with a history of weight loss, changes in bowel habits, and hematochezia had rectal adenocarcinoma. He was palliated with diverting colostomy, followed by radiochemotherapy. Bilateral hydronephrosis was found incidentally on lower abdominal CT scan. He underwent 99mTc dimercaptosuccinic acid scan prior to percutaneous nephrostomy tube placement. Apart from the renal cortex, scintigraphy showed activity in the ascending colon continuous to the activity of the bladder. This indicated urine extravasation on account of a colovesical fistula, complicating postoperative radiation treatment. Here we highlight the contribution of renal cortical scintigraphy in the detection of colovesical fistulas.

Background: Approximately 50% of newly diagnosed cases of non-small-cell lung cancer (NSCLC) are observed in patients >65 years, while 30%-40% of cases occur in patients >70 years., Patients and Methods: The objective of the current study was to determine (i) the number of elderly (>70 years) patients with advanced/metastatic NSCLC enrolled in phase III trials of the Hellenic Oncology Research Group, (ii) the treatment-related toxicity observed in these patients compared with their younger counterparts, and (iii) the differences in terms of response rate, time to tumor progression (TTP), and overall survival (OS) between younger and older patients., Results: Pooled data from five clinical trials including 1845 patients were analyzed; 1421 (77%) and 424 (23%) were <70 years and ≥70 years, respectively. No difference was observed in terms of the overall response rate and TTP. There was an OS difference between young and older patients, with higher risk for death in older patients. However, when the analysis was carried out after omitting a trial that showed a different trend, no difference was observed. Older patients experienced higher toxicity., Conclusions: This report supports the feasibility of chemotherapy treatment for older NSCLC patients. Optimization of treatment of older NSCLC patients requires the design of prospective older-specific phase III trials for these patients.

A phase I study was conducted to determine the maximum tolerated doses (MTD) and the dose-limiting toxicities (DLT) of pemetrexed and docetaxel in patients with advanced unresectable or metastatic non-small-cell lung cancer (NSCLC). Patients were treated with escalating doses of pemetrexed (400-600 mg/m(2) as a 10-min intravenous infusion) and docetaxel (65-85 mg/m(2) as a 1-h intravenous infusion) on day 1, every 3 weeks. An expanded accrual at the level of the recommended dose (RD) had been scheduled. Forty-two patients with metastatic NSCLC were enrolled in the phase I study and 20 additional patients at the RD level. The MTD could not be reached even at the doses of 550 and 85 mg/m(2) for pemetrexed and docetaxel, respectively, which are higher than the recommended dose for each drug given as a single agent. Therefore, the RD was defined at 500 mg/m(2) pemetrexed and 75 mg/m(2) docetaxel. Among the 164 administered chemotherapy cycles (phase I part), there were three episodes of febrile neutropenia whereas 13 (7.9%) and 11 (6.7%) cycles were complicated with grade III and IV neutropenia, respectively. Three patients developed grade III/IV thrombocytopenia. Non-hematologic toxicity was mild with grade III fatigue occurring in three (6.7%) patients. There was no toxic death. The favorable toxicity profile of the regimen was confirmed in patients treated at the RD level. Overall, one complete (CR) and 13 partial responses (PR) (overall response rate = 23; 95% C.I:12.4-33.5%] were documented. The combination of pemetrexed and docetaxel seems to be an effective regimen in NSCLC with acceptable and manageable toxicity, which merits further investigation.

The purpose of the present study was to determine the maximum-tolerated doses (MTDs) and the dose-limiting toxicities of a metronomic administration of oral vinorelbine and cisplatin in patients with advanced/metastatic NSCLC. Twenty-six patients with advanced/metastatic NSCLC were enrolled. Escalating doses of vinorelbine (40-70 mg p.o./trice per week) and cisplatin (70-85 mg/m(2) intravenous infusion) were administered on day 1 every 3 weeks. ΜΤDs were reached at 60 mg thrice/week p.o. for vinorelbine and 85 mg/m(2) for cisplatin. Grade 4 neutropenia, febrile neutropenia and grade 4 diarrhea were the dose-limiting events during the first cycle of chemotherapy. The most common grade III-IV hematologic toxicity was neutropenia occurring in seven (27%) patients, while non-hematological toxicities were relatively infrequent and mostly of grade I or II. Objective responses were observed in 20.8% of patients with measurable disease. The regimen of metronomic administration and cisplatin is feasible and active in patients with NSCLC.

Background/purpose: This study compared front-line treatment with docetaxel or vinorelbine in elderly patients with advanced/metastatic non-small-cell lung cancer (NSCLC)., Patients and Methods: Chemotherapy-naive patients with inoperable stage IIIB and stage IV NSCLC who were > 65 years of age with performance status (PS) of 0-2 were enrolled. Patients were assigned to receive either docetaxel 38 mg/m(2) or vinorelbine 25 mg/m(2) by intravenous (I.V.) infusion on days 1 and 8 every 3 weeks., Results: One hundred thirty elderly patients were enrolled in the study (docetaxel n = 66 and vinorelbine n = 64 patients). The objective response rate was 12.1% and 14.1% in patients treated with docetaxel and vinorelbine, respectively (2P = .799). The median time to tumor progression (TTP) was 2.33 and 1.9 months (2P = .298) and the median overall survival (OS) was 6.07 and 3.87 months (2P = .090) in the docetaxel and vinorelbine arms, respectively. Grade 3/4 neutropenia occurred in 4.5% and 29.7% of patients in the docetaxel arm and vinorelbine arm, respectively (2P < .001). Febrile neutropenia occurred in 1.5% and 1.6% of patients in the docetaxel arm and the vinorelbine arm, respectively (2P = .950) and the use of granulocyte colony-stimulating factor (G-CSF) was more frequent in patients treated with vinorelbine (37.1% vs. 22.5%; 2P < .001). There were no deaths from toxicity. Nonhematologic toxicity was mild., Conclusions: Docetaxel has an efficacy comparable to that of vinorelbine as first-line treatment in elderly patients with NSCLC and has an acceptable toxicity profile. The trial was closed prematurely because of low accrual, thus limiting the strength of the conclusions derived., (Copyright © 2011. Published by Elsevier Inc.)

Purpose: This study evaluates the activity and toxicity of the paclitaxel/carboplatin (PC) doublet versus vinorelbine/carboplatin (VC) doublet as second-line treatment in patients who have advanced non-small-cell lung cancer (NSCLC)., Patients and Treatment: Patients pretreated with front-line docetaxel and gemcitabine were randomized to receive either PC (n = 75), which consisted of paclitaxel at a dose of 140 mg/m(2) and carboplatin area under the curve (AUC3), or VC (n = 78), which consisted of vinorelbine at a dose of 45 mg/m(2) orally and carboplatin AUC3; both drugs were administered on days 1 and 15., Results: The overall response rate was 18.6% (95% confidence interval, 9.85%-27.49%; one complete and 13 partial responses) in the PC arm and 7.7% (95% confidence interval, 1.78%-13.61%; one complete and five partial responses) in the VC arm (P = .056). Median time to tumor progression was 3.5 months (range, 0.3 - 23.73 months) and 3.07 months (range, 0.37-18.5) in the PC and VC arm, respectively (P = .287). Median overall survival was 7.83 months (range, 0.3-45.03 months) and 7.60 months (range, 0.5-30.27 months) for PC and VC arms, respectively (P value = .633). Chemotherapy was well-tolerated and grade III/IV toxicities were relatively infrequent. No toxic deaths were observed., Conclusions: Platinum-based doublets with either paclitaxel or vinorelbine in patients with advanced/metastatic NSCLC pretreated with front-line docetaxel/gemcitabine show comparable efficacy when used in the second-line setting., (Copyright © 2011.

Purpose: To investigate the efficacy and toxicity of the docetaxel and capecitabine combination in patients with previously treated, unresectable adenocarcinoma of the pancreas., Patients and Methods: Patients with pancreatic adenocarcinoma, pre-treated with gemcitabine-based chemotherapy, were treated with capecitabine (800 mg/m(2) orally, twice a day for 14 days) and docetaxel (75 mg/m(2) i.v, on day 1), every 3 weeks. The primary end-point was overall response rate (RR)., Results: Thirty-one patients were enrolled in the study; 93.6% of them had a performance status (PS) of 0-1 and 96.8% had stage IV disease. Patients received a median of 4 cycles/patient, and the main reason for treatment discontinuation was disease progression. Partial response was observed in three (9.7%) patients, stable disease in seven (22.6%) (disease control rate: 32.3%, 95% CI: 15.80-48.71%) and disease progression in 21 (67.6%). The median progression-free survival (PFS) was 2.4 months (95% CI: 1.6-3.13) and the median overall survival (OS) was 6.3 months (95% CI: 3.38-9.23); the estimated 1-year survival rate was 14.7%. Grade III/IV neutropenia occurred in 10 (32.2%) patients and febrile neutropenia in one patient. Other severe non-hematologic toxicities were mild and manageable. After 2 chemotherapy cycles, pain control occurred in 20% of patients and stabilization of body weight in 40%., Conclusion: The combination of docetaxel/capecitabine may confer good disease control associated with improvement of quality of life as second-line chemotherapy in patients with metastatic pancreatic cancer.

Nephrotic-range proteinuria, which denotes structural damage to the glomerular filtration barrier, occurs in 1-2% of bevacizumab-treated patients. The glomerular injury and subsequent proteinuria is probably due to a direct targeting of vascular endothelial growth factor (VEGF). We report a case series of six patients who developed a syndrome characterized by proteinuria and hypertension after starting therapy with bevacizumab and who experienced prolonged progression-free survival. Given that altered glomerular permeability appears to be a direct consequence of VEGF inhibition, we hypothesize that proteinuria may indeed correlate with drug efficacy. Optimizing safe and effective drug dosing is critical to achieve the best therapeutic impact due to limited treatment options for many life-threatening advanced cancers. Clinicians should be aware that the development of proteinuria might serve as a surrogate marker of bevacizumab antitumor efficacy and determine the appropriate criteria for withholding this effective anticancer therapy.

Background: A subgroup analysis of oxaliplatin (LOHP)+irinotecan (CPT-11)+5-fluorouracil (5FU) and leucovorin (LV) (FOLFOXIRI regimen) versus irinotecan+5FU/LV (FOLFIRI regimen) as first-line treatment of patients >65 years old with metastatic colorectal cancer is presented., Patients and Methods: Eighty-two (56%) and 75 (55%) patients with metastatic colorectal cancer aged >65 years were enrolled in the FOLFOXIRI and FOLFIRI regimen, respectively., Results: There was no statistically statistical difference in terms of overall survival or time-to-tumor progression between young and aged patients between the two chemotherapy arms. The objective response rate was significantly lower in older patients treated with FOLFOXIRI (32% vs. 52%; OR: 1.45, 95% CI: 1.06-2.09; p=0.03). Elderly patients experienced a significantly higher incidence of grade 3/4 diarrhea compared to younger patients, irrespectively of the chemotherapy regimen (p=0.005 for FOLFIRI; p=0.017 for FOLFOXIRI). Dose reductions and treatment delays were more frequent in the FOLFOXIRI arm., Conclusion: FOLFOXIRI does not seem to offer substantial benefit compared to FOLFIRI regimen in elderly patients with metastatic colorectal cancer., (Copyright © 2009 Elsevier Ireland Ltd.

Background: Platinum-based chemotherapy represents the standard of care for advanced non-small cell lung cancer (NSCLC) while non-platinum-based regimens are frequently administered in patients with relapse. A retrospective analysis of the sequence administration of these regimens in the first- and second-line setting was performed., Patients and Methods: The records of patients enrolled in the Hellenic Oncology Research Groups's randomized advanced NSCLC trials from February 1997 to September 2006 were retrospectively reviewed. The efficacy of non-platinum-based chemotherapy administered as first- or second-line treatment (n=94, cohort A) was compared to that of non-platinum-based first-line followed by platinum-based second-line chemotherapy (n=267, cohort B), and the reverse sequence (n=123, cohort C)., Results: The objective response rate (ORR) to first-line chemotherapy was higher in cohort C compared to cohort A (45.5% vs. 25.5%, respectively, p=0.002) and cohort B (45.5% vs. 21.3%, p=0.0001). The ORR to second-line therapy was 17%, 13.1% (p=0.349) and 7.3% (p=0.027) in cohorts A, B and C, respectively. Time to progression and the overall survival were comparable among the three cohorts in both first- and second line therapy., Conclusion: Platinum-based first-line chemotherapy improved response rate compared to non-platinum-based regimens; however, the overall survival was comparable, irrespective of the sequence administration of these regimens is the first- and second-line setting.

Aim: To compare the efficacy and tolerance of sequential versus alternate front-line administration of cisplatin-etoposide (PE) and topotecan (T) in patients with extensive stage small cell lung cancer (SCLC)., Patients and Methods: Patients were randomized to receive either 4 cycles PE (cisplatin 80 mg/m(2) i.v. day 1 and etoposide100 mg/m(2)/d i.v. days 1-3 every 21 days) followed by 4 cycles T (1.5 mg/m(2)/d i.v. days 1-5 every 21 days) (arm A, 183 patients) or the same regimens using an alternate sequence (arm B, 181 patients)., Results: There was no significant difference in terms of compliance with treatment, overall response rates (51.4% vs. 55.2%; p=0.458), median response duration (4.3 vs. 5.2 months; p=0.780), median time to tumour progression (5.7 vs. 6.4 months; p=0.494), median overall survival (10.9 vs. 9.8 months; p=0.186) and 1-year survival (43.8% vs. 36.5%) between the two arms. The incidence of severe grade 3-4 haematological and grade 2-4 non-haematological (asthenia, mucositis, diarrhoea and neurotoxicity) toxicity was comparable between the two arms., Conclusion: The comparison of sequential versus alternate administration of cisplatin-etoposide and topotecan as front-line treatment of patients with extensive stage SCLC revealed no clinically meaningful differences in terms of efficacy and tolerance.

Paraneoplastic cerebellar degeneration is a rare neurological disorder that frequently precedes the detection of malignancy. Here, we report the case of a 60 year-old woman with locally advanced squamous cell carcinoma of the tongue who developed a subacute cerebellar syndrome associated with the presence of anti-CV2/CRMP5 antibodies in the cerebrospinal fluid, after achieving complete remission of the primary tumor and the involved cervical lymph nodes by chemoradiation. The patient's symptoms on presentation were dizziness and gait unsteadiness. On examination she showed dysarthria, nystagmus and limb and gait ataxia. The diagnosis of paraneoplastic cerebellar syndrome was made on the basis of the clinical findings and immunological testing that revealed the presence of anti-CV2/CRMP5 antibodies in the patient's cerebrospinal fluid. This syndrome, which is very rare in association with head and neck cancer, commonly precedes the detection of malignancy by a year or more and has been documented in only a few cases after completion of anticancer treatment.
