Abstract
Background: To investigate the changes in transplantability between primary and recurrent Hepatocellular carcinoma (HCC) after hepatic resection (HR) and the risk factors for nontransplantable recurrence (NTR).
Methods: Consecutive 3122 patients who received HR for primary HCC between 2001 and 2019 were analyzed for changes in transplantability. Predictors of survival and NTR were evaluated using a competing risk analysis.
Results: After a median follow-up of 78.3 months, the 5-year overall survival rate was 82.6%. Also, 58.2% of them developed recurrence after a median of 45.6 months. Recurrence occurred in 1205 and 611 patients with primary transplantable and nontransplantable HCC, respectively, of whom 26.1% and 63.2%, respectively, had NTR. Tumor diameter >3 cm [subdistribution hazard ratios (95% CI), 2.00 (1.62-2.48)], major resection [1.20 (1.00-1.43)], pathological grade >2 [1.28 (1.07-1.52)], microvascular invasion [1.74 (1.45-2.08)], and early recurrence (<1 year) [9.22 (7.83-10.87)] were associated with NTR. The overall transplantable pool increased from 72.3% to 77.5%.
Conclusion: Microvascular invasion and early recurrence were risk factors for NTR. Nonetheless, the transplantable pool increased after HR, 41.8% of the patients had no recurrence and may not require liver transplantation. If the patient's liver function is acceptable, HR should be considered the treatment of choice for HCC.
