Risk-Adapted Adjuvant Chemotherapy After Concomitant Fluoropyrimidine-Radiotherapy Neoadjuvant Treatment for Patients With Resectable CT3-4 or N+ Rectal Cancer: Five-Year Disease-Free Survival Results of a Single-Center Series

A risk-adapted adjuvant therapy strategy based on pathologic stage after neoadjuvant chemoradiation is feasible and achieves high rates of 5-year DFS. Patients with good prognostic factors can be treated with adjuvant fluoropyrimidines alone, thus permitting the avoidance of oxaliplatin-derived toxicities.
