Brief Summary: Prospective cohort of patients treated with trifluridine/tipiracil, maximal sample size 250 patients. It is expected, that 89 patients will experience a grade 3-4 neutropenia and will be included in the phase II.
Detailed Description: Trifluridine/tipiracil has demonstrated its efficacy in patients with metastatic colorectal cancer (mCRC) resistant to standard drugs (fluoropyrimidine, oxaliplatin, irinotecan, bevacizumab, and panitumumab or cetuximab in case of RAS wild-type tumors). This treatment has a marketing authorization.

Neutropenia is a classic complication of cytotoxic treatments. Febrile neutropenia are associated with a mortality rate of 9.5% and a hospitalization of 6 days in median. Recent meta-analyses have reported that the use of granulocyte-colony stimulating factor (GCSF) allows to maintain the dose-intensity of cytotoxic treatment and was associated with a better overall survival (OS).

There is currently no clear recommendation for the use of G-CSF with trifluridine/tipiracil.

Unpublished analyses that various clinical parameters may be associated with the risk of neutropenia: age ≥ 65 years, female sex, level of leukocytes at baseline, and time of initial diagnostic to randomization ≥ 36 months.These data are too preliminary to allow proposing a G-CSF primary prophylaxis in a defined subgroup of patients. However, a secondary prophylaxis based on the administration of G-CSF seems efficient, with a prescription from day 14 to day 18.

The aim of this phase II study is to assess the efficacy of the secondary prophylaxis with G-CSF in case of first episode of grade 3-4 neutropenia in the aim to maintain the optimal dose intensity.
