Pilot study of living donor liver transplantation for patients with hepatocellular carcinoma exceeding Milan Criteria (Barcelona Clinic Liver Cancer extended criteria)

A subset of patients with hepatocellular carcinoma (HCC) beyond Milan criteria might obtain acceptable survival outcomes after liver transplantation. Living donor liver transplantation (LDLT) has emerged as a feasible alternative to overcome the paucity of donors. In 2001, we started a protocol for LDLT in Child A-B patients with HCC fulfilling a set of criteriathe Barcelona Clinic Liver Cancer (BCLC) expanded criteriathat expanded the conventional indications of transplantation: 1 tumor7cm, 5 tumors3cm, and 3 tumors5cm without macrovascular invasion or downstaging to Milan after locoregional therapies. We present a prospective cohort of 22 patients with BCLC extended indications based on size/number (n=17) or downstaging (n=5) treated with LDLT between 2001 and 2014. Characteristics of the patients were as follows: median age, 57 years old; males/female, n=20/2; Child-Pugh A/B, n=16/6; and alpha fetoprotein<100ng/mL, n=21. Twelve patients received neoadjuvant locoregional therapies. At the time of transplantation, 12 patients had HCC staging beyond Milan criteria and 10 within. Pathological reports showed that 50% exceeded BCLC expanded criteria. Perioperative mortality was 0%. After a median follow-up of 81 months, the 1-, 3-, 5-, and 10-year survival was 95.5%, 86.4%, 80.2%, and 66.8%, respectively. Overall, 7 patients recurred (range, 9-108 months), and the 5-year and 10-year actuarial recurrence rates were 23.8% and 44.4%, respectively. In conclusion, a proper selection of candidates for extended indications of LDLT for HCC patients provide survival outcomes comparable to those obtained within the Milan criteria, but these results need confirmation.
