Long-term Outcomes of Living-donor Liver Transplantation, Hepatic Resection, and Local Therapy for Hepatocellular Carcinoma with Three <3-cm Nodules in a Single Institute

Background And Aim: Treatment for small hepatocellular carcinoma (HCC) is determined based on the results of a liver function test and the tumor location and spread. The present study compared the outcomes among local therapy, hepatic resection (HR), and living-donor liver transplantation (LDLT) for small HCC in a single institute.

Methods: We compared the overall survival, recurrence-free survival, and cancer-specific survival rates in patients with three HCC nodules <3 cm in size among local therapy, which included radiofrequency ablation (RFA), percutaneous ethanol injection (PEI), and transarterial chemoembolization (TACE), and surgical treatment (HR and LDLT).

Results: One hundred and ninety-seven patients with local therapy (109 RFA, 26 PEI, and 78 TACE), 107 with HR, and 66 with LDLT were enrolled in this study. There was no significant difference in OS among these groups. The recurrence-free, cancer-specific survival (CSS) of LDLT was superior to local therapy and HR. The prognostic factors for the survival were Child-Pugh (CP) Grade B and tumor marker for local therapy and multiple tumors and elevated ALT levels for HR.

Conclusions: For CP grade B patients with HCC of three <3-cm nodule, LDLT could be considered because it resulted in better survival and CSS rates than local therapy.
