No Difference in Overall Survival between Hospital Volumes for Patients with Colorectal Cancer in the Netherlands

BACKGROUND: High-volume hospitals have been associated with improved patient outcomes for tumors with a relatively low incidence that require complex surgeries, such as esophageal and pancreatic cancer. The volume-outcome association for colorectal cancer is under debate. OBJECTIVE: This study investigated whether hospital volume for colorectal cancer is associated with surgical care characteristics and 5-year overall survival. DESIGN: This is a population-based study. SETTING: Data were gathered from the Netherlands Cancer Registry. Hospitals were grouped by volume for colon (<50, 50-74, 75-99, and ≥100 resections per year) and rectum (
