Child-Turcotte-Pugh Score as a Predictive Factor for Long-Term Survival After Repeat Hepatectomy for Recurrent Liver Metastases of Colorectal Cancer

Abstract

We aimed to evaluate the changes in liver function after repeat hepatectomy and their relationship with survival of patient with colorectal cancer. Repeat hepatectomy has been accepted as an effective treatment for recurrent liver metastases; however, how repeat hepatectomy changes the liver function during the follow-up period is not well understood. Data regarding patients underwent R0 resections at initial hepatectomy for colorectal cancer with liver metastasis from 2012 to 2017 were retrospectively reviewed. Patients were divided into groups according to the total number of hepatectomies. Overall survival and Child-Turcotte-Pugh score after hepatectomy were analyzed. Fifty-three patients underwent single hepatectomy and 37 patients underwent repeat hepatectomy. There was no significant difference in the overall survival rates between the 2 groups. At 27 months after the initial hepatectomy, mean Child-Turcotte-Pugh scores of patients with repeat hepatectomy started to become statistically higher than those of patients with single hepatectomy. Overall survival of patients who survived after 27 months from the initial hepatectomy showed a statistical difference between the 2 groups. The total number of liver metastases ≥ 4 and Child-Turcotte-Pugh score ≥ 6 at 27 months after the initial hepatectomy were significant risk factors for overall survival of patient who survived after 27 months from the initial hepatectomy. Liver function after repeat hepatectomy can be deteriorated after a long-term period. Careful approach and continuous assessment of the liver function after hepatectomy are necessary to maintain long-term survival after repeat hepatectomy.
