Anatomical Resection VS. Nonanatomical Resection for Colorectal Liver Metastases With Gene Mutation or Right-sidedness

Liver Metastases Clinical Trial

Official title:
Anatomical Resection Versus Nonanatomical Resection for Colorectal Liver Metastases Patients With Gene Mutation or Right-sidedness: The ARCLAMP Randomized Controlled Trial

Clinical Trial Summary

In this study, colorectal cancer patients with initially resectable liver-only metastases, as prospectively confirmed by a local multidisciplinary team (MDT) according to predefined criteria, will be tested for RAS and BRAF tumor mutation status. Patients with gene mutant or right-sidedness will be randomised between anatomical resection (AR) or nonanatomical resection (NAR). The primary end-point is the relapse-free survival.

Clinical Trial Description

This study is a prospective, single-center, randomized control trial. The major including criteria are (1) Histologically confirmed colorectal cancer initially resectable liver-only metastases ; (2) patient has the opportunity to perform either anatomical resection (AR) or nonanatomical resection (NAR) surgery; (3) the number of metastasis is 1-3; (4) KRAS/NRAS/BRAF mutation or right-sidedness. Patients will be randomised between AR or NAR. Patients will be stratified for gene mutation and right-sidedness. Based upon the segmental anatomy of the liver according to Couinaud system, AR is defined as the resection of one or more complete hepatic segments in our study, including bisegmentectomy, right hemihepatectomy, left hemihepatectomy, extended right hemihepatectomy, extended left hemihepatectomy, single segmentectomy, caudate lobectomy, or a combination thereof. NAR, also called as wedge resection, is defined as the resection of the tumor with a margin of normal parenchyma regardless of the hepatic anatomy. The primary end-point is the relapse-free survival. The secondary end-points are postoperative complication, postoperative mortality, hospital length of stay, and overall survival. ;
