A Decade of Experience Between Open and Minimally Invasive Hepatectomies for Hepatocellular Carcinoma

Abstract

Background and Objectives: Hepatic resection offers promising outcomes for patients with hepatocellular carcinoma (HCC) but can be constrained by factors like patient suitability. Continuous advancements in laparoscopic and robotic technologies have made minimally invasive hepatectomies (MIHs) a viable alternative to open hepatectomies with benefits in terms of recovery and complications. Materials and Methods: We completed a retrospective review on 138 HCC patients who underwent OH or MIH between 2010 and 2020 at the Hume-Lee Transplant Center. Univariate and multivariate analyses were completed on demographic, clinical, and tumor-specific data to assess the impact of these variables on overall and disease-free survival at 1, 3, and 5 years. Preoperative metrics like length of hospital stay (LOS) and operation duration were also evaluated. Results: Of the 109 OH and 29 MIH patients, MIH patients demonstrated shorter LOS and operative times. However, overall survival (OS) and disease-free survival (DFS) were similar between groups, with no significant variations in 1-, 3-, and 5-year survival rates. Age > 60 years and a lack of preoperative transcatheter arterial chemoembolization (TACE) were significant predictors of inferior OS and DFS in multivariate analyses. Conclusions: MIH is an efficient substitute for OH with comparable survival, even in older patients. The reduced LOS and operation time enhance its feasibility, and older patients previously denied for curative resection may qualify for MIH. Preoperative TACE also enhances survival outcomes, emphasizing its general role in managing resectable HCCs. Both robotic and laparoscopic hepatectomies offer acceptable short- and long-term clinical outcomes, highlighting MIH as the standard choice for HCC patients.
