Hepatectomy is accepted as the standard therapy in patients with resectable liver metastases. In recent years, the techniques such as microwave coagulation therapy (MCT) and radiofrequency ablation therapy (RFA) have been developed, so we have many options to treat. We evaluated nineteen subjects with cases of liver metastases who underwent thermoablative procedures with or without hepatectomy. RFA and MCT were used in 6 cases and 2 cases, respectively. In other 11 cases, they received a combined therapy: RFA+hepatectomy in 5 cases, and MCT+hepatectomy in 6 cases. Thermoablative therapy was used for 39 metastatic tumors. The mean tumor size was 13.7 mm, and a local recurrence was observed in 8 nodules (21%). No significant differences were observed in DFS and OS between thermoablative therapy and hepatectomy. Many patients with liver metastases received a repeated treatment, so we have to care about the remnant liver function. We conclude that thermoablative therapy with hepatectomy seems to be a less invasive procedure and effective therapy.

Efficacy and safety of indocyanine green-fluorescence imaging guided liver resection: a single-arm prospective cohort study.

Department of Surgery, Division of Hepato-Biliary-Pancreatic Surgery, Kobe University Graduate School of Medicine, Kobe, Hyogo, Japan.
Purpose: This study aimed to evaluate the efficacy of indocyanine green (ICG)-fluorescence imaging for the identification of hepatic boundaries during liver resection and its advantages in surgical outcomes over conventional methods.
Methods: This prospective, exploratory, single-arm clinical trial included 47 patients with liver tumors who underwent liver resection using ICG-fluorescence imaging (ICG-LR) between 2019 and 2020. The primary outcome measure was the successful identification of hepatic boundaries during liver resection, from the perspective of both the hepatic surface and intrahepatic boundary, using ICG-fluorescence imaging.
Gender Different Impacts of Muscle Mass and Adipose Tissue on Patients With Hepatocellular Carcinoma Undergoing Surgical Resection.

Background & Aims: Body composition is an objective assessment reflecting nutritional status and is highly gender different. Surgical resection, the standard treatment for early-stage hepatocellular carcinoma (HCC), is an energy-consuming major operation that would affect body composition. However, the impacts of body composition on the post-operative prognosis of HCC are still uncertain.

Background/objective: The treatment strategy for hepatocellular carcinoma (HCC) with Vp4 (main trunk) portal vein tumor thrombosis (PVTT) remains controversial due to the dismal prognosis. We aimed to investigate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) plus lenvatinib and tislelizumab in these patients.
Methods: This multicenter retrospective study included treatment-naive HCC patients with Vp4 PVTT from 2017 to 2022.

Department of Surgery, Medical Faculty Mannheim, Universitätsmedizin Mannheim, Heidelberg University, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Germany.
Introduction: The impact of the distance of the tumor from the main hepatic vessels (DTV), such as the Glissonean pedicle or hepatic veins, on oncological outcomes for Hepatocellular carcinoma (HCC) patients is relatively understudied. Therefore, the objective of this study was to explore the correlation between DTV and survival in patients with HCC after curative hepatic resection.
Methods: Consecutive patients who underwent curative-intent liver surgery for HCC between April 2018 and May 2023 were identified from a prospective database.

Background: Neutrophil-to-lymphocyte ratio (NLR) is a promising prognostic marker for patients undergoing hepatectomy for colorectal liver metastases (CRLM). However, its prognostic value in patients receiving neoadjuvant therapy (NAT) has not been sufficiently addressed.
Methods: From 2013 to 2023, a cohort of 692 patients with CRLM receiving hepatectomy were enrolled in five centers.
