Article 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 (≤ 6 months) and late recurrence who underwent repeat hepatectomy were compared.
Methods: Consecutive adult patients undergoing hepatectomy for CRLM between June 2000 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 ± 3.6 vs. 1.9 ± 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.

Surgery for postoperative intrahepatic recurrence after curative resection for hepatocellular carcinoma: Repeat hepatectomy versus salvage liver transplantation.
Glob Health Med

Liver resection (LR) remains a cornerstone curative option for patients with hepatocellular carcinoma (HCC), and yet the high rate of postoperative intrahepatic recurrence poses a significant clinical challenge. Despite numerous attempts, no adjuvant therapy has shown definitive efficacy in preventing recurrence. In this context, salvage liver transplantation (SLT) and repeat hepatectomy (RH) have emerged as key curative strategies for recurrent disease.

Objective: To prospectively assess the incidence of residual disease in disappearing liver metastases (DLM) and evaluate associated oncologic outcomes.
Summary Background Data: DLM are colorectal liver metastases that become undetectable on imaging after chemotherapy. Although DLM are increasingly observed with modern systemic therapy and imaging, their clinical significance and appropriate management remain unclear.

Background: Liver resection is still the most effective and curative treatment for recurrent liver cancer, laparoscopic repeat liver resection (LRLR) offers an option for recurrent liver cancer due to invasive advantages. However, multicenter, large-sample population-based LRLR has rarely been reported. We aimed to assess the advantages and drawbacks of LRLR compared with laparoscopic and open surgery for recurrent liver cancer by meta-analysis.

Background/aim: Repeat hepatectomy for recurrent hepatocellular carcinoma (rHCC) can, sometimes, be difficult due to postoperative adhesions and altered liver anatomy. This study aimed to examine the advantages of laparoscopic repeat hepatectomy (LRH) compared to open repeat hepatectomy (ORH).
Patients And Methods: One hundred and forty-six patients who underwent repeat hepatectomy for rHCC between April 2016 and December 2023 at Kurume University School of Medicine were enrolled.

Background: Ferroptosis, a distinctive form of cell death induced by iron-dependent lipid peroxidation, is implicated in various biological processes, including liver diseases. Establishing an iron overload-induced ferroptosis model and identifying hepatic gene signatures associated with ferroptosis are crucial for understanding its role in liver pathogenesis.
Methods: F-box and leucine-rich repeat protein 5 (FBXL5) is a substrate-recognition component of the SCF E3 ligase complex that restricts intracellular iron levels.
