Key clinical point: Compared with transcatheter arterial chemoembolization (TACE) followed by radiotherapy (RT), administering RT before TACE leads to better survival outcomes in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT).
Major finding: Patients who received RT+TACE vs TACE+RT had significantly longer median progression-free survival (6.6 vs 4.2 months; hazard ratio [HR] 0.66; P = .030), with the prolongation of median overall survival being marginally significant (15.4 vs 11.5 months; HR 0.68; P = .054).
Study details: Findings are from a randomized controlled study including 120 patients with unresectable HCC and PVTT who were randomly assigned (1:1) to receive RT+TACE or TACE+RT.
Disclosures: This study was supported by the Clinical Research Plan of Shanghai Shenkang Hospital Development Center, China, among others. The authors declared no conflicts of interest.
