Triplet chemotherapy with or without bevacizumab as first line treatment for metastatic colorectal cancer: An AGEO multicenter real-world study.

Background: Prior trials validated triplet chemotherapy (Tri-CT) with bevacizumab as first line treatment for metastatic colorectal cancer (mCRC) but real-world data are scarce and practices remain heterogeneous.

Aims: To evaluate Tri-CT +/- bevacizumab efficacy and safety, and to identify factors influencing treatment decisions.

Methods: The COLOTRIP retrospective study enrolled mCRC patients treated from 2014 to 2019 in 14 French centers.

Perioperative Cetuximab with Cisplatin and 5-Fluorouracil in Esogastric Adenocarcinoma: A Phase II Study.

Purpose: While perioperative chemotherapy provides a survival benefit over surgery alone in gastric and gastroesophageal junction (G/GEJ) adenocarcinomas, the results need to be improved. This study aimed to evaluate the efficacy and safety of perioperative cetuximab combined with 5-fluorouracil and cisplatin.

Patients And Methods: Patients received six cycles of cetuximab, cisplatin, and simplified LV5FU2 before and after surgery.

Daily practices in chemotherapy for advanced gastric or gastroesophageal junction adenocarcinoma: METESTOMAC French prospective cohort.

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.

FOLFIRI plus BEvacizumab or aFLIbercept after FOLFOX-bevacizumab failure for COlorectal cancer (BEFLICO): An AGEO multicenter study.

After failure of first line FOLFOX-bevacizumab for metastatic colorectal cancer (mCRC), adding either bevacizumab or aflibercept to second-line FOLFIRI increases survival compared to FOLFIRI alone. In this French retrospective multicentre cohort, we included patients with a mCRC treated with either FOLFIRI-aflibercept or FOLFIRI-bevacizumab. The primary endpoint was overall survival (OS), and secondary endpoints were progression-free survival (PFS), disease control rate (DCR: CR + PR + SD) and safety.

Phase III randomized trial comparing systemic versus intra-arterial oxaliplatin, combined with LV5FU2 +/- irinotecan and a targeted therapy, in the first-line treatment of metastatic colorectal cancer restricted to the liver (OSCAR): PRODIGE 49.

Introduction: In patients with unresectable liver metastases from colorectal cancer (CRCLM), systemic doublet or triplet chemotherapy and targeted therapy is considered a standard first-line treatment. Hepatic arterial infusion of oxaliplatin (HAI-ox) generates a high response rate, but this still needs to be confirmed in a randomized trial. We incorporated HAI-ox in doublet or triplet + targeted therapy to validate its efficacy.

Randomized Phase II Trial Evaluating Two Sequential Treatments in First Line of Metastatic Pancreatic Cancer: Results of the PANOPTIMOX-PRODIGE 35 Trial.

Purpose: Metastatic pancreatic cancer (mPC) still harbors a dismal prognosis. Our previous trial (PRODIGE 4-ACCORD 11) demonstrated the superiority of 6-month chemotherapy with fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) over gemcitabine for overall survival. The high limiting oxaliplatin-related neurotoxicity supports the evaluation of an oxaliplatin stop-and-go strategy and a sequential strategy in mPC.

Chemotherapy use in end-of-life digestive cancer patients: a retrospective AGEO observational study.

Background: The use of chemotherapy (CT) near the end-of-life (EOL) is an important issue in oncology since it could degrade quality of life. CT near EOL is still poorly studied, with no dedicated study in gastrointestinal (GI) cancer patients.

Aim: To analyze in GI cancer patients the factors associated with the use of CT within 3- and 1-month before patients' death.

Prognostic factors of colorectal cancer patients with brain metastases.

Introduction: Brain metastases (BMs) from colorectal cancer (CRC) are rare (≈2%) but are increasing with the improvement of CRC prognosis. The main objective of this study was to evaluate the prognostic factors of BM from CRC.

Materials And Methods: This multicenter retrospective study included all consecutive patients with BM from CRC diagnosed between 2000 and 2017.

Objective: The aim of this study was to evaluate the efficacy and safety of perioperative chemotherapy in patients with locally advanced nonmetastatic CC.

Methods: This is a French multicenter randomized phase II trial in patients with resectable high-risk T3, T4, and/or N2 CC on baseline computed tomography (CT) scan.

FOLFOX alone or combined with rilotumumab or panitumumab as first-line treatment for patients with advanced gastroesophageal adenocarcinoma (PRODIGE 17-ACCORD 20-MEGA): a randomised, open-label, three-arm phase II trial.

Background: Epidermal growth factor receptor (EGFR) and hepatocyte growth factor (HGF)/mesenchymal-epithelial transition (MET) pathways, which promote tumour growth and proliferation, are often deregulated in advanced gastroesophageal adenocarcinomas. We assessed whether adding panitumumab (an EGFR inhibitor) or rilotumumab (a HGF inhibitor) to first-line fluoropyrimidine-based and platinum-based chemotherapy (modified oxaliplatin, leucovorin and fluorouracil [mFOLFOX6]) benefits to patients with advanced gastroesophageal adenocarcinoma.

Patients And Methods: This phase II, open-label, randomised, three-arm study enrolled patients ≥18 years, with advanced gastroesophageal adenocarcinoma, Eastern Cooperative Oncology Group performance status 0-1 and no known HER2 overexpression.

Aflibercept in combination with 5‑fluorouracil (5‑FU)/irinotecan improves overall survival in the second‑line therapy of patients with metastatic colorectal cancer (mCRC). In this study, we evaluated the effects of aflibercept in first‑line therapy with FOLFOX followed by maintenance with fluoropyrimidine. VELVET was a prospective, single‑arm multicenter phase II study (completed).

Resection of small bowel adenocarcinoma metastases: Results of the ARCAD-NADEGE cohort study.

Introduction: Data are lacking with regard to curative resection of metastasis from small bowel adenocarcinoma (SBA). This study evaluated outcomes and prognostic factors in patients with curatively resected metastatic SBA.

Methods: A series of 34 patients undergoing resection of metastatic SBA from January 2009 to November 2014 at French centers were included into this cohort study.

Efficacy of a docetaxel-5FU-oxaliplatin regimen (TEFOX) in first-line treatment of advanced gastric signet ring cell carcinoma: an AGEO multicentre study.

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.

Trastuzumab beyond progression in patients with HER2-positive advanced gastric adenocarcinoma: a multicenter AGEO study.

Introduction: Trastuzumab in combination with platinum-based chemotherapy is the standard first-line regimen in HER2-positive advanced gastric cancer. However, there are very few data concerning efficacy of continuing trastuzumab beyond first-line progression.

Methods: This retrospective multicenter study included all consecutive patients with HER2-positive advanced gastric or gastro-esophageal junction (GEJ) adenocarcinoma who received a second-line of chemotherapy with or without trastuzumab after progression on platinum-based chemotherapy plus trastuzumab.

Perioperative chemotherapy with FOLFOX in resectable gastroesophageal adenocarcinoma in real life practice: An AGEO multicenter retrospective study.

Purpose: Perioperative chemotherapy with 5-fluorouracil and cisplatin, with or without epirubicin, improves overall survival in resectable gastroesophageal junction and gastric adenocarcinoma. The aim of this retrospective multicenter study was to evaluate the safety and efficacy of perioperative chemotherapy with a FOLFOX-based regimen.

Patients And Methods: We enrolled patients with resectable gastric or gastroesophageal adenocarcinoma, who had at least 3 cycles of a pre-operative FOLFOX-based regimen.

Efficacy of Adjuvant Chemotherapy in Colon Cancer With Microsatellite Instability: A Large Multicenter AGEO Study.

Background: Deficient mismatch repair (dMMR) colon cancer (CC) is reportedly resistant to 5-fluorouracil (5FU) adjuvant chemotherapy while preliminary data suggest chemosensitivity to oxaliplatin. We assessed the efficacy of fluoropyrimidine with and without oxaliplatin in a large cohort of dMMR CC patients.

Methods: This retrospective multicenter study included all consecutive patients who underwent curative surgical resection for stage II or III dMMR CC between 2000 and 2011.

High-Dose FOLFIRI plus Bevacizumab in the Treatment of Metastatic Colorectal Cancer Patients with Two Different UGT1A1 Genotypes: FFCD 0504 Study.

High-dose FOLFIRI has an acceptable safety profile and promising efficacy. UDP-glucuronosyltransferase: (UGT1A1) polymorphism may be predictive of toxicity and efficacy of irinotecan. This phase II study aimed to evaluate the combination of high-dose FOLFIRI plus bevacizumab in patients with previously untreated metastatic colorectal cancer (MCRC) based on their UGT1A1 genotype.
