Colon Cancer (High-risk Stage III: pT4N1 or pT1 to 4 N2) | Drug: Irinotecan Drug: Folfox Protocol | Phase 3 |
After inclusion and non-inclusion criteria have been fulfilled and the patient consent has been obtained, the patient will be included and randomized in the trial. The maximum delay allowed between the signature of the consent form by the patient and the randomization in the study is 28 days.
The randomization procedure using minimization method will allocate the treatments mFOLFIRINOX or mFOLFOX 6 with a 1:1 ratio, and will be stratified by the following criteria:
- Perforation or urgent surgery versus no perforation and no urgent surgery.
- T1-T3N2 vs T4aN1 versus T4bN1 versus T4N2.
- Right colon (right of splenic flexure) vs left colon.
- Country (France vs Canada vs Italy). Patient eligible and who have signed the informed consent will be randomized in one of the two treatments arms and will receive every 14 days their treatment for a duration of 12 cycles.

- Disease Free Survival (DFS) [ Time Frame: 3 YEARS after inclusion ]
DFS :
defined as the time from the date of randomization up to the date of:
- first local, regional or distant relapse;
- second colorectal cancer;
- death from any cause included treatment-related death.
- Disease Free Survival [ Time Frame: 2 YEARS after inclusion ]
DFS :
defined as the time from the date of randomization up to the date of:
- first local, regional or distant relapse;
- second colorectal cancer;
- death from any cause included treatment-related death.
- Overall Survival [ Time Frame: 5 YEARS after inclusion ]Overall Survival (OS) is defined as the time from the date of randomization to the date of documented death from any cause
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: 2 YEARS after inclusion ]
Safety of the study treatment will be assessed on occurrence of Adverse Events (AEs), intake of concomitant treatments, per-treatment arising changes in physical examination, vital signs (blood pressure, pulse rate and body temperature), ECG, and clinical laboratory tests (biochemistry, haematology). Safety parameters will be graded based on NCI CTCAE v4.03 classification.
The following parameters will be particularly followed:
The incidence of haematological toxicities (grade 3-4, in particular neutropenia and febrile neutropenia); The incidence of GI toxicities, in particular diarrhea; The incidence of peripheral neuropathy.
