  • Patient affiliated to a social security scheme
Exclusion Criteria
  • Patients already treated with trifluridine tipiracil or irinotecan in the past 5 years
  • Uncontrolled intercurrent illness
  • Previous malignancies other than adequately treated in situ carcinoma of the uterine cervix or basal or squamous cell carcinoma of the skin, unless there has been a disease-free interval of at least 3 years
  • Pregnant or breastfeeding women, women of childbearing age not having had a negative pregnancy test
  • Any known specific contraindication or allergy to the treatments used in the study†

Primary Outcome Measures
NameTimeMethod
The time to recurrence (TTR)From date of randomization until the date of first documented progression or date of death from colorectal cancer

The time to recurrence (TTR), in patients treated by FOLFIRI vs surveillance inside the study and in patients treated by Trifluridine Tipiracil vs surveillance inside the study. This TTR is defined as time from randomization to disease recurrence including locoregional or metastatic relapse, death with evidence of recurrence and death from CRC cause.
