Purpose:
To determine the risks and benefits of repeat hepatectomy for hepatic metastases from colorectal cancer.
Methods:
During a recent 10-year-period, 106 patients underwent hepatectomy for hepatic metastases from colorectal cancer, in our hospital. Recurrence developed in the liver in 57 of these patients, 27 of whom underwent repeat hepatectomy. We reviewed the outcomes of these 27 patients.
Results:
There were three complications after the first hepatectomy and six complications after the second hepatectomy, but there was no perioperative mortality after the first or second hepatectomy. The median survival from the date of second hepatectomy was 41 months with an actuarial 5-year survival rate of 48.7%. Patients who underwent repeat hepatectomy had significantly higher survival rates from the time of first hepatectomy than those who did not. Univariate analysis showed that among the prognostic factors of repeat hepatectomy, only a disease-free interval (DFI) between the first and second hepatectomy of more than 1 year was significantly predictive of a better outcome (P = 0.047).
Conclusion:
Repeat hepatectomy for recurrent colorectal metastases can be performed safely with acceptable mortality and morbidity rates, and can help to extend survival, if the DFI between the first and second hepatectomy is longer than 1 year.
