Advances in rectal protection technique in prostate cancer radiotherapy / 中华放射肿瘤学杂志

ABSTRACT

Radiation therapy (RT) is a well-established and widely used treatment modality for prostate cancer. As prostate-rectum proximity contributes to rectal toxicity, there is growing interest in rectal protection. Technical advances have enabled the reduction of rectal injury. To improve the safety of prostate cancer radiotherapy and minimize the rectal toxicity of irradiation, the advances in rectal protection technique during prostate cancer radiotherapy, including technical advances of radiation therapy, image-guided radiotherapy, application of endorectal balloons, and use of rectum spacers, were reviewed, aiming to provide reference for improving the safety of prostate cancer radiotherapy and alleviating rectal radiation injury.
