Recurrent Hepatocellular Carcinoma After Liver Transplantation: Analysis of Risk Factors

Area of Science:

• Hepatobiliary Surgery
• Transplant Oncology
• Gastroenterology

Background:

• Survival following liver transplantation (LT) for hepatocellular carcinoma (HCC) is critically affected by tumor recurrence.
• Understanding factors predicting recurrence is vital for improving post-transplant outcomes in HCC patients.

Purpose of the Study:

• To investigate the impact of tumor recurrence on survival after LT for HCC.
• To identify histological factors associated with an increased risk of tumor recurrence post-LT.

Main Methods:

• Retrospective analysis of 181 patients undergoing LT for HCC between 1990 and 2014.
• Patients were divided into recurrence and no-recurrence groups.
• Univariate and multivariate regression analyses were employed to identify risk factors for recurrence.

Main Results:

• High Edmondson-Steiner grades (G3-G4) were significantly associated with tumor recurrence.
• Tumor size, vascular invasion, and capsular invasion emerged as independent risk factors for recurrence in multivariate analysis.

Conclusions:

• Tumor recurrence is a defining factor for survival in patients who have undergone LT for HCC.
• Histological factors such as tumor grade, size, and invasion are crucial in predicting recurrence risk and subsequent patient survival.
