Stereotactic body radiotherapy for localized prostate cancer / 国际肿瘤学杂志

ABSTRACT

External-beam radiotherapy is one of the principle treatment options for localized prostate cancer. Conventionally fractionated radiotherapy is widely used in clinical practice. Studies have shown that prostate cancer is highly sensitive to hypofractionated radiotherapy, also known as stereotactic body radiotherapy (SBRT), and increasing radiotherapy dose can significantly improve the local control rate of tumor. A number of recently completed researches have shown that SBRT is as effective as conventionally fractionated radiotherapy. In terms of radiation toxicity, the short-term toxicity of SBRT is more obvious than that of conventionally fractionated radiotherapy, but there is no significant difference in long-term toxicity. SBRT can provide more convenience for patients, and the medical cost is lower, so it has a great clinical application prospect.
