Background:
It is unclear which patients with recurrence after a second hepatectomy will benefit from a third hepatectomy.
Methods:
Patients who underwent hepatectomy for colorectal liver metastasis (CRLM) between April 2005 and July 2021 were included. Factors affecting recurrence after each hepatectomy were analyzed.
Results:
Sixty-four of the 167 patients who had recurrence after the first hepatectomy underwent a second hepatectomy. Then, 46 patients had recurrence and 18 patients did not have recurrence after the second hepatectomy. Sixteen patients who underwent a third hepatectomy had better overall survival (OS) than those who did not (52 vs. 31 months, p = 0.043). However, the multivariate analysis demonstrated that only tumor size (>5 cm) during the second hepatectomy (p = 0.022) and carbohydrate antigen 19-9 (CA 19-9) level (>50 U/ml) (p = 0.041) at recurrence after the second hepatectomy were poor prognostic factors for OS.
Conclusion:
While a third hepatectomy can be performed if it is technically and oncologically appropriate, tumor size >5 cm and CA 19-9 >50 U/ml should be considered in terms of long-term outcomes before proceeding to surgery.
