Analyze the dynamics of incorporation of 5-fluorouracil into cancer cell ribosomes from liver metastases of patient with metastatic colon cancer.

This is a monocentric, prospective, non-interventional cohort study in adult patients with metastatic colon cancer with hepatics metastasis.

Tumour samples collected for this study include:

• A fragment of the previously operated primary tumor: FFIP block and/or archived frozen tumor if available.
• A fragment of the liver metastasis(s) performed as part of standard metastasis surgery, this fragment will include a tumor area and a healthy area within the margin of excision. These samples collected in a fresh state will be analyzed immediately.

Inclusion Criteria:

• Patient with metastatic colon cancer operated on and followed up at the Centre Leon Berard for liver metastasis.
• Patient affiliated to social security

Exclusion Criteria:

• Other pathologies that may interfere with biological evaluation, in particular known hepatic cirrhosis, whatever its origin, other liver overload diseases (hemochromatosis, Wilson's disease), but excluding steatosis (which can be chemo-induced).
