| Abstract: | To compare the outcomes of transarterial chemoembolization (TACE) alone with those of TACE combined with external beam radiation therapy (EBRT) in patients with hepatocellular carcinoma (HCC) in a multicenter randomized study. From 2017 to 2022, 74 HCC patients with tumors confined to the liver without vascular invasion were treated with either TACE only (TACE group, 39 patients) or TACE combined with EBRT (TACE + EBRT group, 35 patients). The primary outcome measured was overall survival (OS). Secondary outcomes included progression-free survival (PFS), local tumor control, and the assessment of treatment-related toxicity. Due to slow accrual, the trial was closed prematurely after enrolling 74 patients. All patients received 2 cycles of TACE before randomization. The TACE and TACE + EBRT groups showed comparable patient and tumor characteristics. The TACE group underwent a median of 3 TACE cycles, and the TACE + EBRT group received 2 cycles of TACE, and a median of 5500 cGy in 15 fractions. For the TACE group, the median local control (LC) duration was 13.1 months, whereas for the TACE + EBRT group, the median LC was not achieved (P <.001). The PFS was recorded at 11.6 months in the TACE group compared with 15.4 months in the TACE + EBRT group (P =.072). The median OS reached 36.8 months for the TACE group and extended to 47.1 months for the TACE + EBRT group (P =.654). The incidence of toxicity was comparable between both groups. Although the number of patients enrolled in this clinical trial did not meet expectations. TACE combined with EBRT was shown to be more effective than TACE alone in improving LC without increasing toxicity, whereas PFS and OS were slightly improved. TACE + EBRT can be used as a standard treatment option for patients with inoperable but confined intrahepatic HCC. [ABSTRACT FROM AUTHOR] |
