Popis: Abstract Background Many previous studies evaluated a combination of transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) for treating early hepatocellular carcinoma (HCC); however, studies evaluating combination therapy for beyond-the-Milan criteria HCC are scarce. Methods A total of 120 patients with beyond-the-Milan criteria HCC who have viable tumour after first TACE will be enrolled in this multi-institutional, parallel, pragmatic, randomized controlled trial. Patients with metastasis, vascular invasion, or a sum of tumour diameter > 8 cm will be excluded. Eligible patients will be randomly assigned to combination TACE and RFA therapy or TACE monotherapy groups. Patients in the combination therapy group will receive a second TACE and subsequent RFA at the viable tumour. Patients in the TACE monotherapy group will receive only second TACE. Patients in both groups will undergo magnetic resonance imaging 4–6 weeks after second TACE. The primary endpoint is 1-month tumour response, and secondary endpoints are progression-free survival, overall response rate, number of treatments until CR, overall survival, and change in liver function. Discussion Although TACE can be used to treat intermediate-stage HCC, it is difficult to achieve CR by first TACE in most intermediate-stage patients. Recent studies show a survival advantage of combination therapy over monotherapy. However, most studies evaluating combination therapy included patients with a single tumour sized
