Abstract
Radiation therapy is a primary treatment for the unresectable hepatocellular carcinoma (HCC),including internal radiotherapy,three-dimensional conformal radiotherapy,three-dimensional intensity modulated radiotherapy (IMRT),stereotactic radiotherapy and radiotherapy combined with transcatheter arterial chemoembolization (TACE).For small lesions,residual or recurrent lesions after external irradiation,the internal radiotherapy can purposefully place radionuclides to increase the amount of radiation in target organs and reduce the amount of radiation in normal tissue.For the patients with unclear tumor boundary,thrombosis,lymph node metastasis or local recurrence,three-dimensional conformal radiotherapy,IMRT and radiotherapy combined with TACE can better make the target high-dose distribution shape fit with three-dimensional space accurately,and improve the local control rate.
