Loco-regional therapy in patients with Milan Criteria-compliant hepatocellular carcinoma and short waitlist time to transplant: an outcome analysis

AbstractObjectivesLiver transplantation (LT) in Milan Criteria (MC) hepatocellular carcinoma (HCC) has excellent outcomes. Pre-transplant loco-regional therapy (LRT) has been used to downstage HCC to meet the MC. However, its benefit in patients with a brief waiting time to transplant remains unclear. This study evaluated outcomes in patients with short waitlist times to LT for MC-compliant HCC.MethodsPatients undergoing LT for MC HCC at either of two transplant centres between 2002 and 2009 were retrospectively evaluated for outcome. Patients for whom post-transplant follow-up amounted to <12 months were excluded.ResultsA total of 225 patients were included, 93 (41.3%) of whom received neoadjuvant LRT. The median waiting time to transplant was 48 days. Mean post-transplant follow-up was 32.2 months. Overall and disease-free survival at 1 year, 3 years and 5 years were 93.1%, 82.4% and 72.6%, and 91.3%, 79.3% and 70.6%, respectively. There was no difference in overall (P= 0.94) and disease-free survival (P= 0.94) between groups who received and did not receive pre-LT LRT. There were also no disparities in survival or tumour recurrence among categories of patients (with single tumours measuring
