Current concepts in hepatic resection for hepatocellular carcinoma in cirrhotic patients.

Hepatocellular carcinoma (HCC) is one of the most frequent neoplasms worldwide and in most cases it is associated with liver cirrhosis. Liver resection is considered the most potentially curative therapy for HCC patients when liver transplantation is not an option or is not immediately accessible. This review is aimed at investigating the current concepts that drive the surgical choice in the treatment of HCC in cirrhotic patients; Eastern and Western perspectives are highlighted. An extensive literature review of the last two decades was performed, on topics covering various aspects of hepatic resection. Early post-operative and long-term outcome measures adopted were firstly analyzed in an attempt to define an optimal standardization useful for research comparison. The need to avoid the development of post-hepatectomy liver failure represents the "conditio sine qua non" of surgical choice and the role of the current tools available for the assessment of liver function reserve were investigated. Results of hepatic resection in relationship with tumor burden were compared with those of available competing strategies, namely, radiofrequency ablation for early stages, and trans-arterial chemoembolization for intermediate and advanced stages. Finally, the choice for anatomical versus non-anatomical, as well as the role of laparoscopic approach, was overviewed. The literature review suggests that partial hepatectomy for HCC should be considered in the context of multi-disciplinary evaluation of cirrhotic patients. Scientific research on HCC has moved, in recent years, from surgical therapy toward non-surgical approaches and most of the literature regarding topics debated in the present review is represented by observational studies, whereas very few well-designed randomized controlled trials are currently available; thus, no robust recommendations can be derived.
