The primary objective is to validate that the Immunoscore® test (IS0 to IS4) is able to identify patients with high risk (IS 0-1) of relapse or death whichever occurs first among Stage III patients under oxaliplatin-based adjuvant therapy. Then the prognostic value of Immunoscore® Colon to predict disease free survival (DFS) will be assessed in Stage III patients under Oxaliplatin treatment in each arm of the IDEA trial (6- months and 3-months treatment). Finally, the additive value of the Immunoscore® test to stratify the DFS will be evaluated among standard clinical and biological parameters and tumor features.
Adult patients of both genders who have underwent surgical resection of stage III colon carcinoma and randomised to receive a 6-month or 3-month adjuvant therapy with modified FOLFOX 6 or CAPOX in the IDEA France trial.

disease-free survival (DFS)
DFS is defined as the time from randomization to relapse or death, whichever occurred first. Secondary colon cancers are regarded as DFS events, whereas non-colon tumors are to be disregarded in the analysis. Patients with no defined events observed during the follow-up will be censored at the date of last disease evaluation which showed no evidence of relapse, or secondary primary colon cancer.
