Abstract
Background: The prognosis for unresectable perihilar cholangiocarcinoma (phCCA) is extremely poor. Liver transplantation in combination with neoadjuvant chemoradiation therapy has become the treatment of choice for unresectable phCCA in the USA. In 2018, we launched a prospective study to evaluate the safety and efficacy of living donor liver transplantation (LDLT) for unresectable phCCA.
Methods: A total of 10 patients were enrolled in this study between 2018 and 2024. Finally, five patients with unresectable phCCA underwent LDLT after neoadjuvant chemotherapy, radiation, and staging laparotomy, while the other five patients dropped out of the protocol.
Results: The median follow-up period was 23.7 months. The overall survival rate for the five patients who underwent LDLT was 100% after one year. Hepatic artery thrombosis and delayed gastric emptying occurred in two and three cases, respectively. The histological efficacy of preoperative treatment was grade IIb and III, according to the Evans classification, in all five patients. All surgical margins and dissected lymph nodes were negative. Four patients were alive with no evidence of disease recurrence while one patient had recurrence 10 months after LDLT.
Conclusions: LDLT is feasible and may be a last-resort treatment option for unresectable phCCA, although the long-term outcomes need to be carefully monitored.
Clinical trial register and clinical registration number: The UMIN registration number for this study is 000033348.
