Recent evidence suggests that single repeat metastasectomy may provide survival benefits for selected patients experiencing hepatic or pulmonary recurrences following initial hepatectomy for colorectal carcinoma metastases. The aim of this retrospective study was to clarify the efficacy of multiple repeat resections of intra- and extrahepatic recurrences following initial hepatectomy. A total of 100 patients underwent curative partial hepatectomy as the initial procedure for colorectal carcinoma metastases. Tumor relapse after initial hepatectomy was seen in 72 patients, of whom 28 underwent 45 repeat metastasectomies of various sites: 18 patients underwent a single repeat metastasectomy, and 10 underwent multiple repeat metastasectomies. The overall survival rate at 5 years after initial hepatectomy was 36.6%, while the 5-year survival rate after repeat metastasectomy in the 28 patients was 43.6%. The outcome of initial hepatectomy was comparable with that of repeat metastasectomy (p = 0.6924). Among the 28 patients undergoing repeat metastasectomy, the outcome of resection of intrahepatic recurrences in 11 patients was comparable with the outcome of resection of extrahepatic recurrences in 17 patients(p = 0.3926). The outcome of multiple repeat metastasectomies compared favorably with single repeat metastasectomy(p = 0.1803). Multivariate analysis(p < 0.0001) showed that repeat metastasectomy was the strongest prognostic factor. In conclusion, both single and multiple repeat resections of intra- and extrahepatic recurrences after initial hepatectomy are efficacious in colorectal carcinoma patients. Repeat resection should be considered for any resectable recurrences after hepatectomy.
