Abstract
Hepatocellular carcinoma (HCC) is the most common primary tumor with an increased risk of mortality and morbidity. Treatment for HCC varies based on the progressivity of disease. Radiotherapy such as stereotactic body radiotherapy (SBRT) plays an important role in the treatment of HCC. The role of radiotherapy used to be very limited to liver tumors, but recently, radiotherapy with SBRT technique has shown very promising results, both in primary liver cancer and liver metastasis. This review shows the role of radiotherapy in HCC for every stage of HCC (monotherapy, combined or bridging therapy). In liver metastasis cases, radiotherapy shows an excellent, similar, and better local control when compared with radiofrequency ablation (depending on tumor status).
