Abstract: Background: Liver recurrence after resection of colorectal liver metastases (CRLM) is frequent. Repeat hepatectomy has been shown to have satisfactory perioperative results. However, the long-term outcomes and the benefits for patients with early recurrence have not been clarified. The aim of this study was to compare the short-and long-term outcomes of patients undergoing single hepatectomy and repeat hepatectomy for CRLM. Additionally, the oncological outcomes of patients with early (& LE; 6 months) and late recurrence who underwent repeat hepatectomy were compared. Methods: Consecutive adult patients undergoing hepatectomy for CRLM between June 20 0 0 and February 2020 were included and divided into two groups: single hepatectomy and repeat hepatectomy. Results: A total of 709 patients were included: 649 in the single hepatectomy group and 60 in the repeat hepatectomy group. Patients in the repeat hepatectomy group underwent more cycles of preoperative chemotherapy [4 (3-6) vs. 3 (2-4), P = 0.003]. Patients in the single hepatectomy group more frequently underwent major hepatectomies (34.5% vs. 16.7%, P = 0.004) and had a greater number of lesions resected (2.9 & PLUSMN; 3.6 vs. 1.9 & PLUSMN; 1.8, P = 0.011). There was no increase in operative time, estimated blood loss, length of hospital stay, complications, or mortality in the repeat hepatectomy group. There were no differences in overall survival ( P = 0.626) and disease-free survival ( P = 0.579) between the two groups. Similarly, for patients underwent repeat hepatectomy, no difference was observed between the early and late recurrence groups in terms of overall survival ( P = 0.771) or disease-free survival ( P = 0.350). Conclusions: Repeat hepatectomy is feasible and safe, with similar short-and long-term outcomes when compared to single hepatectomy. Surgical treatment of early liver recurrence offers similar oncological outcomes to those obtained for late recurrence.
