The integration of new technologies has raised an interest in liver tumor radiotherapy,with literature evolving to support its efficacy.These advances,particularly stereotactic body radiation therapy(SBRT),have been critical in improving local control or potential cure in liver lesions not amenable to first-line surgical resection or radiofrequency ablation.Active investigation of SBRT,particularly for hepatocellular carcinoma(HCC),has recently started,yielding promising local control rates.In addition,data suggest a possibility that SBRT can be an alternative option for HCC unfit for other local therapies.However,information on optimal treatment indications,doses,and methods remains limited.In HCC,significant differences in patient characteristics and treatment availability exist by country.In addition,the prognosis of HCC is greatly influenced by underlying liver dysfunction and treatment itself in addition to tumor stage.Since they are closely linked to treatment approach,it is important to understand these differences in interpreting outcomes from various reports.Further studies are required to validate and maximize the efficacy of SBRT by a large,multi-institutional setting.
The integration of new technologies has raised an interest in liver tumor radiotherapy, with literature evolving to support its efficacy. The advances, particularly stereotactic body radiation therapy (SBRT), have been critical in improving local control or potential cure in liver lesions not amenable to first-line surgical resection or radiofrequency ablation. Active investigation of SBRT, particularly for hepatocellular carcinoma (HCC), has recently started, yielding promising local control rates. In addition, data suggest a possibility that SBRT can be an alternative option for HCC unfit for other local therapies. Despite, information on optimal treatment indications, doses, and methods remains limited. In HCC, significant differences in patient characteristics and treatment availability exist by country. In addition, the prognosis of HCC is greatly influenced by underlying liver dysfunction and treatment itself in addition to tumor stage.Since they are added to the tumor stage.Since they are closely linked to treatment approach, it is impo rtant to understand these differences in interpreting outcomes from various reports. Future studies are required to validate and maximize the efficacy of SBRT by a large, multi-institutional setting.
