Immunoscore Is Prognostic in Low-Risk and High-Risk Stage III Colon Carcinomas Treated With Adjuvant Infusional Fluorouracil, Leucovorin, and Oxaliplatin in a Phase III Trial.

ABSTRACT:

Purpose

The recommended duration of adjuvant fluoropyrimidine and oxaliplatin chemotherapy for patients with stage III colon cancer is based on tumor classification into clinically low-risk (T_1-3 N₁) and high-risk (T₄ or N₂) groups. We determined whether Immunoscore can enhance prognostication within these risk groups.

Materials and methods

Patients with stage III colon carcinomas (N = 600) were randomly selected from the infusional fluorouracil, leucovorin, and oxaliplatin arm of adjuvant trial NCCTG N0147 (Alliance for Clinical Trials in Oncology). Tumors were evaluated for Immunoscore that quantifies CD3⁺ and CD8⁺ T-cell densities in the tumor center and invasive margin by digital image analysis. Disease-fr
