Reproducibility of vaginal immobilization balloons overnight for cervical cancer brachytherapy.

J Contemp Brachytherapy 2021 Jun 13;13(3):280-285. Epub 2021 May 13.

Department of Radiation Oncology, University of Arizona College of Medicine, Tucson, USA.

Purpose: The use of vaginal immobilization balloons placed into the vagina for immobilization of tandem and ovoid (T+O) applicator during high-dose-rate (HDR) brachytherapy delivery has been used at our institution, and seems to have improved our patient comfort, decreased procedure time, and minimized applicator misplacement. We aimed to show that these balloons, while originally marketed for single-day use, are safe and maintain applicator positioning/dosimetry when left overnight for treatment delivery on sequential days.

Material And Methods: Forty-two paired computed tomography (CT) scans from thirteen patients who underwent T+O HDR treatments on sequential days with vaginal immobilization balloons overnight were retrospectively compared to calculate mean change of balloon volumes and balloon/T+O distance to bony landmarks.
