Updated 5-year survival and exploratory T x N subset analyses of ACTS-CC trial: a randomised controlled trial of S-1 versus tegafur-uracil/leucovorin as adjuvant chemotherapy for stage III colon cancer.

ABSTRACT:

Objective

Adjuvant Chemotherapy Trial of TS-1 for Colon Cancer (ACTS-CC), a randomised phase III trial, demonstrated that adjuvant therapy with S-1 for stage III colon cancer was non-inferior in 3-year disease-free survival (DFS) to that of tegafur-uracil plus leucovorin (UFT/LV). We updated DFS and overall survival (OS) and performed T x N subset analysis.

Methods

A total of 1518 patients with curatively resected stage III colon cancer were randomly assigned to receive S-1 (80-120  mg/day on days 1-28 every 42 days, four courses) or UFT/LV (UFT: 300-600  mg/day and LV: 75  mg/day on days 1-28 every 35 days, five courses).

Results

The 5-year DFS rates of the S-1 and UFT/LV group were 70.2 % and 66.9 %, respectively (HR 0.88; 95%  CI 0.74 to 1.06; p=0.177), and non-inf
