Uterine perforation and its dosimetric implications in cervical cancer high-dose-rate brachytherapy
PURPOSE To retrospectively assess the incidence of sub-serosal and uterine perforation of intra-uterine tandem in intracavitary high-dose-rate (HDR) brachytherapy for cervical cancer, and to evaluate its dosimetric implications on computed tomography (CT)-based treatment planning. MATERIAL AND METHODS Computed tomography images and brachytherapy plans of cervical cancer patients treated from ...
متن کامل”Maximum dose” points in cervical and endometrial cancer medium dose rate brachytherapy
Background: Best dose distribution in target volume and control of Organ at Risk (OAR) dose are the two main goals in brachytherapy. Materials and Methods: In this study in vivo dosimetry in 4 rectal points was performed by Transillumination Dosimeter (TLD) s and the measured doses were compared in different patients. One point was reported to have the maximum dose in each patient and the very ...
متن کاملA study of high-dose-rate intracavitary brachytherapy boost for curative treatment of uterine cervical cancer
PURPOSE This study assessed the trial of boost intracavitary brachytherapy (ICBT) for the patients of uterine cervical cancer with residual malignant cells detected at the final stage of ICBT. MATERIAL AND METHODS This is a retrospective analysis of 75 patients with cervical cancer treated radically with external beam radiotherapy and high-dose-rate intracavitary brachytherapy between August ...

متن کاملEvaluating variation of Hot Spot Location in order to radiobiological calculation of Organ at Risk in High-dose- rate Brachytherapy of Cervical Cancer
Introduction: Gynecological malignancies present challenges in determining an appropriate volumetric dose due to the highly variable physiologic activity of the surrounding tissue. Because of the high doses used in brachytherapy, surrounding structures have the potential to move around in the dose region and receive unknown amounts of radiation. Calculating hotspot region from ...
