Chemotherapy for patients with colorectal liver metastases who underwent curative resection improves long-term outcomes: systematic review and meta-analysis.

Abstract

Hepatic resection is considered the standard of care for patients with resectable colorectal liver metastases (CRLM), but the benefits of using systemic chemotherapy for these patients have not been completely proven. Although systemic chemotherapy is likely to improve recurrence-free survival (RFS), no differences in overall survival (OS) have been demonstrated to date. This study aimed to compare surgery plus systemic chemotherapy, regardless timing of administration, with surgery alone, analyzing long-term outcomes for patients with CRLM who underwent liver resection with curative intent.
