Criteria

Inclusion Criteria:

1. Patients with histologically proven metastatic colorectal cancer in progression after a first line of chemotherapy +/- targeted therapy

2. Patients must have been treated for their metastatic disease with one of the following regimens as first-line therapy:

• FOLFOX (Oxaliplatine, 5-Fluoro-uracil)

• FOLFIRI (Irinotecan, 5-Fluoro-uracil)

• FOLFIRINOX (Irinotecan, oxaplipatin, 5-Fluoro-uracil) or FOLFOXIRI (irinotecan, oxaliplatin, 5-Fluoro-uracil)

• FOLFOX and anti-VEGFA (bevacizumab only)

• FOLFIRI and anti-VEGFA (bevacizumab only)

• FOLFIRINOX or FOLFOXIRI and anti-VEGFA (bevacizumab only)

• FOLFOX and anti-EGFR (Epiderman Growth Factor Recepto)

• FOLFIRI and anti-EGFR

• FOLFIRINOX or FOLFOXIRI and anti-EGFR

Of note, a chemotherapy prescribed for metastases occurring within six months after the end of an adjuvant chemotherapy are considered as a second line of therapy.

3. Patients should have a history of resistance to first line chemotherapy defined by:

• Disease progression during the first line of their metastatic disease, less than 3 months after the last exposition to chemotherapy (even a chemotherapy regimen mentioned above or a 5-Fluoro-uracil-based maintenance therapy).

9. Adequate bone marrow, liver and renal functions.

• Haemoglobin ≥ 9 g/dL; absolute neutrophil count (ANC) ≥ 1.5 x 109/L; platelets ≥ 100 x 109/L

2. Current participation in a study of an investigational agent. Patients might be included at least 21 days following the last investigational agent administration.

3. Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before inclusion in the trial;

4. Patient under judicial protection (curators, autorship) and/or deprived of freedom,
