Three Months of Adjuvant Therapy Adequate for Stage III Colon Cancer

The IDEA Collaboration is a prospective, pre-planned pooled analysis of 6 concurrently conducted randomized phase III trials, which included 12,834 patients from 12 countries. They concluded that a risk-based approach has to be taken when making adjuvant chemotherapy recommendations for patients with stage III colon cancer. Three months of adjuvant chemotherapy is adequate for patients with T1-3, N1 disease. This study data was presented at 2017 ASCO Annual Meeting.
