Background: Triplet chemotherapy, with docetaxel-5FU-oxaliplatin (TEFOX), has yielded promising results in patients with advanced and operable gastric adenocarcinoma. This may prove useful in treating signet ring cell carcinoma (SRCC), which is known to be chemoresistant and has a poor prognosis. We therefore evaluated TEFOX in patients with untreated advanced SRCC.

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice.

Introduction: Patients with gastroenteropancreatic (GEP), metastatic or locally advanced, non-resectable, grade 3 poorly-differentiated neuroendocrine carcinoma (NEC) are treated with cisplatin (or carboplatin)-etoposide in first-line palliative chemotherapy (CT1). However, nearly all patients will develop resistance and there is no standard second-line treatment.

Aim: PRODIGE 41-BEVANEC is an academic randomized, phase II study designed to evaluate the efficacy of bevacizumab in combination with FOLFIRI after failure of CT1 in unknown primary NEC and GEP-NEC.

Background: Early tumour shrinkage has been associated with improved survival in patients receiving cetuximab-based systemic chemotherapy for liver metastases from colorectal cancer (LM-CRC). We tested this hypothesis for previously treated LM-CRC patients receiving cetuximab (500 mg/m) and triplet hepatic artery infusion (HAI) within European trial OPTILIV.

Methods: Irinotecan (180 mg/m), 5-fluorouracil (2800 mg/m) and oxaliplatin (85 mg/m) were given as chronomodulated or conventional delivery.

Background: There is currently no standard second-line treatment for metastatic pancreatic adenocarcinoma (MPA), and progression-free survival is consistently <4 months in this setting. The aim of this study was to evaluate the efficacy and tolerability of Nab-paclitaxel plus gemcitabine (A+G) after Folfirinox failure in MPA.

Methods: From February 2013 to July 2014, all consecutive patients treated with A+G for histologically proven MPA after Folfirinox failure were prospectively enrolled in 12 French centres.

Adjuvant treatment has clearly demonstrated its efficacy and safety in resected colon cancer patients, saving thousands of lives every year worldwide. Six months adjuvant chemotherapy combining 5FU and oxaliplatin (FOLFOX or XELOX regimens) is indicated in stage III colon cancer after surgical removal of the primary tumor. The benefit of adjuvant chemotherapy seems less evident in stage II colon cancer, but this treatment should be discussed in patients with "high risk" factors for recurrence.

Introduction: Folfirinox has shown a benefit in terms of survival and quality of life in first line treatment of metastatic pancreatic cancer. However, efficacy of second line chemotherapy after folfirinox is still limited. Gemcitabine plus Nab-paclitaxel have been recently validated as first line treatment with an increased overall survival compared to gemcitabine.

Background: Docetaxel-cisplatin-5-FU chemotherapy is superior to 5-FU-cisplatin in terms of response rate and survival in advanced gastric cancer (AGC), but is more toxic. Oxaliplatin is better tolerated than cisplatin, which it can effectively replace in this setting. We hypothesize that incorporating docetaxel into a simplified FOLFOX regimen should be a tolerable and effective option in first-line treatment of AGC.

Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies. Therapeutic options depend on location of the primitive tumor, its expandability, its hormonal symptoms and its differentiation. Though relatively rare, with an increasing incidence and a high prevalence digestive neuroendocrine tumors (DNETs) are ranked just behind colorectal cancer as the most common digestive cancers in developed countries.

Exocrine pancreatic cancer has a very poor prognosis. R0 resection of the tumor is to date the only potentially curative approach, but less than 20% of patients are eligible for a curative surgery at diagnosis. Until recently, gemcitabine was the standard treatment for advanced and metastatic pancreatic cancer patients, since it was shown more than a decade ago to induce clinical benefit and to improve survival when compared to weekly bolus 5-fluorouracil.

Background: The anti-VEGF antibody bevacizumab associated with an irinotecan or oxaliplatin-based chemotherapy was proved to be superior to the chemotherapy alone in first or second line treatment of metastatic colorectal cancer (mCRC). However, it was reported to have no efficacy in 3rd or later-line, alone or with 5FU. The aim of this study was to evaluate the activity of bevacizumab combined with FOLFIRI or FOLFOX in mCRC who have failed prior chemotherapy with fluoropyrimidine plus irinotecan and/or oxaliplatin.
