RESUMEN
BACKGROUND: Around 50% of gastric cancers are diagnosed at an advanced stage. Several chemotherapy regimens are now internationally validated. Few data are available on the routine daily management of advanced gastric or gastroesophageal junction cancers. We aimed to describe chemotherapy practices, tolerance, and efficacy overall survival (OS) and Progression free survival (PFS) in a prospective French cohort. METHODS: Patients starting palliative chemotherapy were prospectively enrolled in 49 French centres. The primary objective was to report and describe patients' characteristics and treatment strategies. Secondary objectives were OS, PFS, objective response rate, adverse events rate, performance status deterioration during the chemotherapy. RESULTS: A total of 182 patients were included; 179 were analysed. Most patients received platinium-based chemotherapy as the first treatment and FOLFIRI as second; 62.0% of patients received a second line, and 32.4% a third line. More than two thirds of Her2-positive patients were first treated with trastuzumab. The FOLFIRI regimen was the most frequently used second-line therapy. Median OS was 13.3 months, similar whatever the chemotherapy or combinations used in the first line. One- and 2-year OS increased with the number of chemotherapy lines received, from respectively 24.7% and 5.7% (1 line), to 46.9% and 12.4% (2 lines) and 88.1% and 29.9% (3 or more lines) (p < 0.0001). CONCLUSION: Our study showed that treatment strategies in France are based on a succession of doublets, making it possible to offer a second and third line of treatment more often. This treatment strategy must be taken into account for future trials with immunotherapy combinations.

PURPOSE: Whether triplet chemotherapy is superior to doublet chemotherapy in advanced biliary tract cancer (BTC) is unknown. METHODS: In this open-label, randomized phase II-III study, patients with locally advanced or metastatic BTC and an Eastern Cooperative Oncology Group performance status of 0 or 1 were randomly assigned (1:1) to receive oxaliplatin, irinotecan, and infusional fluorouracil (mFOLFIRINOX), or cisplatin and gemcitabine (CISGEM) for a maximum of 6 months. We report the results of the phase II part, where the primary end point was the 6-month progression-free survival (PFS) rate among the patients who received at least one dose of treatment (modified intention-to-treat population) according to Response Evaluation Criteria in Solid Tumors version 1.1 (statistical assumptions: 6-month PFS rate ≥ 59%, 73% expected). RESULTS: A total of 191 patients (modified intention-to-treat population, 185: mFOLFIRINOX, 92; CISGEM, 93) were randomly assigned in 43 French centers. After a median follow-up of 21 months, the 6-month PFS rate was 44.6% (90% CI, 35.7 to 53.7) in the mFOLFIRINOX arm and 47.3% (90% CI, 38.4 to 56.3) in the CISGEM arm. Median PFS was 6.2 months (95% CI, 5.5 to 7.8) in the mFOLFIRINOX arm and 7.4 months (95% CI, 5.6 to 8.7) in the CISGEM arm. Median overall survival was 11.7 months (95% CI, 9.5 to 14.2) in the mFOLFIRINOX arm and 13.8 months (95% CI, 10.9 to 16.1) in the CISGEM arm. Adverse events ≥ grade 3 occurred in 72.8% of patients in the mFOLFIRINOX arm and 72.0% of patients in the CISGEM arm (toxic deaths: mFOLFIRINOX arm, two; CISGEM arm, one). CONCLUSION: mFOLFIRINOX triplet chemotherapy did not meet the primary study end point. CISGEM doublet chemotherapy remains the first-line standard in advanced BTC.

PURPOSE: The identification and referral of patients in need of palliative care should be improved. The French society for palliative support and care recommended to use the PALLIA-10 questionnaire and its score greater than 3 to refer patients to palliative care. We explored the use of the PALLIA-10 questionnaire and its related score in a population of advanced cancer patients. METHODS: This prospective multicentric study is to be conducted in authorized French comprehensive cancer centers on hospitalized patients on a given day. We aimed to use the PALLIA-10 score to determine the proportion of palliative patients with a score >3. Main secondary endpoints were to determine the proportion of patients already managed by palliative care teams at the study date or referred to palliative care in six following months, the prevalence of patients with a score greater than 5, and the overall survival using the predefined thresholds of 3 and 5. RESULTS: In 2015, eighteen French cancer centers enrolled 840 patients, including 687 (82%) palliative patients. 479 (69.5%) patients had a score >3, 230 (33.5%) had a score >5, 216 (31.4%) patients were already followed-up by a palliative care team, 152 patients were finally referred to PC in the six subsequent months. The PALLIA-10 score appeared as a reliable predictive (adjusted ORRef≤3 : 1.9 [1.17-3.16] and 3.59 [2.18-5.91]) and prognostic (adjusted HRRef≤3 = 1.58 [95%CI 1.20-2.08] and 2.18 [95%CI 1.63-2.92]) factor for patients scored 4-5 and >5, respectively. CONCLUSION: The PALLIA-10 questionnaire is an easy-to-use tool to refer cancer inpatients to palliative care in current practice. However a score greater than 5 using the PALLIA-10 questionnaire would be more appropriate for advanced cancer patients hospitalized in comprehensive cancer center.

BACKGROUND: Despite its toxicity, cisplatin every 3 weeks (q3w) is the standard potentiation of chemo-radiotherapy for head and neck squamous cell carcinoma. This study aimed to determine whether weekly cisplatin (q1w) could be a safe and effective alternative. PATIENTS AND METHODS: Two hundred and sixty-two patients with head and neck squamous cell carcinoma, irradiated in our institution with cisplatin (q1w or q3w) between January 2004 and December 2008, were retrospectively included. Overall survival (OS) and progression-free survival (PFS) were evaluated. Survival distributions were estimated by Kaplan-Meier method and compared using the log-rank test. Prognostic effect of chemo-radiotherapy was explored using Cox model. RESULTS: A total of 165 and 97 patients received q1w and q3w cisplatin, respectively. Median age, stage at diagnosis, alcohol consumption, intensity-modulated radiation therapy use, median weight, and renal failure before radiotherapy were significantly different, showing lower risk in the q3w group. Q3w cisplatin was found to be more toxic in terms of weight loss, renal failure, worse chemotherapy plan completion, and grade 3/4 mucositis and dermatitis, with more patients requiring analgesics, secondary hospitalization, and radiotherapy interruption (≥3 days), and patients affected by long-term toxicities. With a median follow-up of 73 months (95% confidence interval [CI] [68.9-76.2]), OS was found to be significantly better with q3w (5 years OS: 62.3%; 95% CI [51.6-71.3]) than with q1w cisplatin (5 years OS: 52.6%; 95% CI [44.5-60.0]) (log-rank P=0.0146). More number of patients treated according to the q1w schedule experienced a recurrence: 47.3% vs 30.9% (P=0.009). Thus, the PFS for q3w schedule was found to be globally better (5 years PFS: 55.8%; 95% CI [45.0-65.3]) than for q1w schedule (5 years PFS: 43.6%; 95% CI [35.9-51.0]) (log-rank P=0.0161). However, both multivariate analyses, OS and PFS, produce no significant hazard ratio for chemo-radiotherapy modality once adjusted on unbalanced covariates according to the descriptive analysis. CONCLUSION: Though q1w seemed to be safer than q3w according to the descriptive analysis, multivariate analyses failed to conclude about its efficiency. Therefore, we conclude that the q3w schedule should remain the standard and prospective comparisons are needed.

BACKGROUND: Everolimus, an mTOR inhibitor with immunosuppressive properties, is used in several types of advanced tumors. Materials and METHODS: We describe the first two cases of Pneumocystis jirovecii pneumonia in patients given everolimus for metastatic pancreatic neuroendocrine tumors. RESULTS: The first patient presented with respiratory symptoms in the context of grade 4 lymphopenia 2 weeks after starting everolimus; the diagnosis of Pneumocystis jirovecii pneumonia was made post-mortem. After suspecting everolimus-related interstitial pneumonitis in the second patient, Pneumocystis jirovecii was detected, and cotrimoxazole therapy led to a favorable outcome. CONCLUSION: Everolimus may induce pneumonitis, lymphopenia and opportunistic infections. The time from treatment initiation to opportunistic infection may be short. Risk factors in oncology deserve further identification in order to start prophylaxis without delay.

The role of deleted in colorectal carcinoma (DCC) as a tumour suppressor has been a matter of debate for the past 15 years. DCC gene expression is lost or markedly reduced in the majority of advanced colorectal cancers and, by functioning as a dependence receptor, DCC has been shown to induce apoptosis unless engaged by its ligand, netrin-1 (ref. 2). However, so far no animal model has supported the view that the DCC loss-of-function is causally implicated as predisposing to aggressive cancer development. To investigate the role of DCC-induced apoptosis in the control of tumour progression, here we created a mouse model in which the pro-apoptotic activity of DCC is genetically silenced. Although the loss of DCC-induced apoptosis in this mouse model is not associated with a major disorganization of the intestines, it leads to spontaneous intestinal neoplasia at a relatively low frequency. Loss of DCC-induced apoptosis is also associated with an increase in the number and aggressiveness of intestinal tumours in a predisposing APC mutant context, resulting in the development of highly invasive adenocarcinomas. These results demonstrate that DCC functions as a tumour suppressor via its ability to trigger tumour cell apoptosis.

Surgery and radiotherapy are generally not an option for recurrent/metastatic head and neck squamous cell carcinoma. Chemotherapy is the only possible treatment. The five major drugs active in monotherapy are methotrexate, cisplatin, 5-fluorouracil (5-FU), cetuximab (an antiepidermal growth factor receptor antibody) and taxanes (paclitaxel or docetaxel). They allow 10-25% response with a median survival of approximately 6-8 months. Various chemotherapy doublets may achieve higher response rates, up to 45-50%, but overall survival remains unchanged. As recurrent patients are often symptomatic, better response is associated with better quality of life and the standard treatment for patients with performance status 0-1 is the combination of cisplatin and 5-FU. Recently, the triplet cisplatin-5-FU-cetuximab, which has been shown to result in an increased response rate and a significantly better median survival of 10.4 months, has become the new treatment standard.
