Purpose and design: Optimal surgical strategy for resectable synchronous colorectal cancer with liver metastasis (SCRLM) remains a therapeutic dilemma. Multiple retrospective studies including several meta-analyses have been published since 2001 to help facilitate the decision making process and identify the optimal surgical approach. Controversy limits the generalization of available data to draw conclusions. A review of available literature on appropriate surgical timing may alleviate confusion among physicians and promote a more evidence based approach.
Results and conclusion: Current evidence supports the feasibility, safety, and equivalent oncological outcomes of simultaneous curative resection of stage IV colorectal cancer with liver metastasis in appropriately selected patients.
