Image-Guided Multi-Channel Cylinder Brachytherapy for Gynecologic Cancers Involving the Vagina: Initial Experience with Vaginal Dose-Volume Parameters

Image-guided high-dose-rate multichannel vaginal cylinder (MCVC) brachytherapy (BT) permits conformal dose delivery to a vaginal tumor while sparing surrounding organs-at-risk. Due to the proximity of the peripheral channels to the tumor and cylinder surface, the adjacent vaginal mucosa is a dose-limiting structure when using MCVC, however, specific dose-volume limitations are not well characterized. We explored vaginal dose-volume parameters in a series of consecutive patients treated with MCVC for gynecologic cancers involving the vagina.
