Dosimetric comparison of bladder, rectal, and vaginal surface doses between ovoids and cylinder-based vaginal brachytherapy in carcinoma of the endometrium.

Purpose: The study aims to estimate the differences in vaginal surface, bladder, and rectal doses when adjuvant intracavitary brachytherapy is carried out with ovoids or with vaginal cylinders, in postoperative carcinoma endometrium and to assess the difference in variability in organs at risk (OAR) doses and thereby the reproducibility of application in subsequent sittings.

Materials And Methods: Fifteen patients each received vaginal brachytherapy with ovoid and cylindrical applicators. The dose received by 0.
