Management of colorectal cancer with synchronous liver metastases: impact of multidisciplinary case conference review

Abstract

Background: While no evidence exists to support mandatory multidisciplinary case conference (MCC) review for patients with synchronous colorectal cancer and liver metastases, this unique population may benefit greatly from multidisciplinary discussion.

Methods: We retrospectively identified patients who underwent liver resection with curative intent for colorectal liver metastases (CRLM) at a tertiary center between January 2008 and June 2015. The characteristics of patients discussed at a weekly regional MCC were examined, and the effect of MCC review on treatment approach was assessed.

Results: Sixty-six patients underwent elective surgery for synchronous colorectal cancer and liver metastases during the study period. Twenty-nine patients (44%) were presented at a MCC. Presentation was associated with greater likelihood of undergoing simultaneous or liver-first resection (P≤0.0001), with no difference in the extent of liver resection or location of primary tumor between the groups. A greater proportion of patients received chemotherapy and/or radiation following MCC discussion, without statistical significance.

Conclusions: The treatment approach for patients with synchronous colorectal cancer and liver metastases may be significantly altered based on MCC review. Multidisciplinary discussion is advocated in order to facilitate equal access to individualized care.
