The side effects and dose-effect relationship of vagina in the brachytherapy for cervical cancer / 中华放射医学与防护杂志

ABSTRACT

Brachytherapy is irreplaceable in definitive radiotherapy and postoperative radiotherapy for cervical cancer. Since the vagina is adjacent to the cervix in terms of anatomical position and the vaginal applicator is placed in the vagina between the bladder and the rectum, the absorbed dose of the vagina is extremely uneven and difficult to evaluate. This review expounds the present vaginal side effects, vaginal dose evaluation method, dose-effect relationship between dose and side effects, and dose limits in brachytherapy for cervical cancer, to provide a certain reference for the clinical practice of the brachytherapy for cervical cancer.
