Abstract | BACKGROUND Graft hepatocellular carcinoma (HCC) recurrence after liver transplant is more frequently encountered. Graft hepatectomy is technically challenging and is associated with high morbidity. Stereotactic body radiation therapy (SBRT) has been shown to be safe and effective for the treatment of primary HCC. However, its role in HCC recurrence in a liver graft remains unclear. AIM To evaluate the safety and efficacy of SBRT for the treatment of graft HCC recurrence after liver transplantation. METHODS A retrospective study was conducted. From 2012 to 2018, 6 patients with intrahepatic HCC recurrence after liver transplant were treated with SBRT at Queen Mary Hospital, the University of Hong Kong. The primary outcome was time to overall disease progression and secondary outcomes were time to local progression and best local response, as assessed with the Modified response Evaluation Criteria for Solid Tumours criteria. Patients were monitored for treatment related toxicities and graft dysfunction. RESULTS A total of 9 treatment courses were given for 13 tumours. The median tumour size was 2.3 cm (range 0.7-3.6 cm). Two (22%) patients had inferior vena cava tumour thrombus. The best local treatment response was: 5 (55%) complete response, 1 (11%) partial response and 3 (33%) stable disease. After a median follow up duration of 15.5 mo, no local progression or mortality was yet observed. The median time to overall disease progression was 6.5 mo. There were 6 regional progression in the liver graft (67%) and 2 distant progression in the lung (22%). There was no grade 3 or above toxicity and there was no graft dysfunction after SBRT. CONCLUSION SBRT appears to be safe in this context. Regional progression is the mode of failure. ©The Author(s) 2020. |
