Recurrence-Free Survival Dynamics Following Adjuvant Chemotherapy for Resected Cancers of the Gastrointestinal Tract: A Systematic Review of Randomized Controlled Trials.
INTRODUCTION Adjuvant chemotherapy can improve recurrence-free survival (RFS) in gastrointestinal malignancies. Previous review of phase III randomized controlled trials (RCTs) for colorectal cancer observed that RFS improvements were driven by early divergences during active chemotherapy; late recurrences were not inf...
