A complication-free course ensures a survival advantage in patients after regional therapy for metastatic colorectal cancer.

Hepatic artery infusional (HAI) chemotherapy has been shown to favorably impact outcome in patients with metastatic colorectal cancer, but complications often preclude complete treatment. The purpose of this study was to determine whether HAI complications impact survival in these patients. Patients undergoing HAI pump placement at our institution from September 2001 to July 2004 were separated into terciles based on the number of treatments completed: < or = 1 (none), 2 to 4 (partial), and > or = 5 (complete).
