Abstract

The treatment of colorectal liver metastasis (CRLM) has progressed markedly in the past decades. Main contributions stem from improvement in surgical approach and applications of chemotherapy. The availability of several perioperative and surgical techniques, including portal vein embolization, ablation techniques, and two-stage hepatectomies, has expanded surgical indications. In addition, preoperative imaging methods have contributed to these advances.

In patients with high oncological risk of recurrence, or initially unresectable CRLM, highly individualized treatment regimens are becoming more widely utilized. These patients should be evaluated for surgical resection after several cycles of chemotherapy given the survival benefit afforded by liver resection for CRLM. Several biomarkers, including RAS mutation, BRAF mutation, and microsatellite stability, have become essential in guiding therapy. Immunotherapy has recently been highlighted, especially for cases of microsatellite instability. Looking forward, biomarkers will likely to continue to guide individualized treatment patterns.

Liver transplantation as an option for patients with unresectable CRLM may boast comparable outcomes to patients with primary liver tumors, but it remains controversial considering the limited supply of donor livers.

Management of CRLM requires the complex decision making process common to contemporary tumor board discussions, and a multidisciplinary approach likely figures into future directions of management for CRLM.
