Brief summary

Primary Objective: -Evaluate the resection rate (R0/R1) in current practice for aflibercept in combination with irinotecan plus 5-fluorouracil (FOLFIRI) in patients treated for metastatic colorectal cancer (mCRC) after failure of an oxaliplatin-containing regimen Secondary Objectives: * Evaluate overall survival, progression-free survival and relapse-free survival. * Evaluate conversion rates (initially unresectable disease which became resectable after chemotherapy, with R0/R1 resection). * Evaluate histological and radiological response rates. * Evaluate rate of postoperative complications. * Evaluate safety.

Detailed description

The estimated inclusion period is 45 months. Patient follow-up is 24 months and the total study duration is 69 months. Last patient status (alive or dead) collected before database lock.

Inclusion criteria

* All patients treated with aflibercept in combination with FOLFIRI for mCRC after failure of an oxaliplatin-containing regimen (including patients pretreated with bevacizumab or anti-EGFR and patients treated with oxaliplatin in the adjuvant setting). * Exclusively or predominantly hepatic metastases (≤ 5 pulmonary nodules \< 2 cm). * Age \> 18 years. * Signed consent for collection of personal and medical data. * Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.

Exclusion criteria

* Concomitant participation in a clinical trial. * Patient receiving concomitant anti-VEGF agents and/or receiving aflibercept as part of a clinical trial or in a compassionate use program. * Patient receiving aflibercept in combination with chemotherapy other than FOLFIRI. * Patient with contra-indication to surgery. The above information is not intended to contain all considerations relevant to a potential participation in a clinical trial.
