AbstractPrimary liver cancer is the seventh most common cancer worldwide and is the second leading cause of cancer-related death. Hepatocellular carcinoma (HCC) accounts for three-quarters of primary liver cancers and less than a third of patients present with curable disease. Liver-directed therapy is essential for the treatment of patients with unresectable HCC and the advancement of stereotactic body radiation therapy (SBRT) has made radiation a safe and effective treatment option in a range of clinical presentations. In this review, we discuss the technical aspects of SBRT and the general approach to treatment of HCC. We explore the use of SBRT for bridging to transplant, downstaging, and the treatment of large tumors and portal vein tumor thrombus. Although there is limited high-quality randomized data, we review the evidence comparing SBRT with other liver-directed therapies and explore areas for future investigation.

Abstract Background: To evaluate the clinical outcomes of patients who received stereotactic body radiation therapy (SBRT) for single viable hepatocellular carcinoma (HCC) at the site of incomplete transarterial chemoembolization (TACE).Methods: Incomplete TACE was defined as (1) evidence of viable HCC at the site of TACE on follow-up images following one or more consecutive TACEs, (2) no definite tumor staining on celiac angiogram, or (3) no definite iodized oil uptake on post-embolization angiogram or computed tomography. A total of 302 patients were treated between 2012 and 2017 at Asan Medical Center (Seoul, South Korea). Doses of 10–15 Gy per fraction were given over 3–4 consecutive days. Treatment-related adverse events were evaluated according to the common terminology criteria for adverse events, version 4.03.Results: The median follow-up duration was 32.9 months (interquartile range [IQR], 23.6–41.7) and the median tumor size was 2.0 cm (range, 0.7–6.9). The local control (LC) and overall survival rates at 3 years were 91.2% and 72.7%, respectively. 95.4% of the tumors reached complete response (CR) during the entire follow-up period (anyCR). The median interval from SBRT to anyCR was 3.4 months (IQR, 1.9–4.7), and 39.9% and 83.3% of the lesions reached CR at 3- and 6-months after SBRT, respectively. Radiation-induced liver disease was observed in 8 (2.6%) patients. No patients experienced gastroduodenal bleeding within the radiation field.Conclusion: SBRT should be considered a feasible salvage treatment option for HCC after incomplete TACE.
