BACKGROUND Purpose of this study was to identify predictors of vaginal ulcer after CT based three-dimensional image-guided high-dose-rate interstitial brachytherapy (HDR-ISBT) for gynecologic malignancies. METHODS Records were reviewed for 44 female (14 with primary disease and 30 with recurrence) with gynecological malignancies treated with HDR-ISBT with or without external beam radiation th...
PURPOSE We perform a clinical retrospective study to determine whether a vaginal balloon-packing system provides a dosimetric reduction to organs at risk (OARs) versus traditional gauze packing for gynecological high-dose-rate brachytherapy (HDR-BT). We also test various balloon filling materials for optimizing imaging quality. MATERIAL AND METHODS Filling materials for balloon-packing were e...
PURPOSE The path of subsequent dwell positions of an afterloader source being moved through a ring applicator for cervix cancer brachytherapy deviates from an ideal circle and the position of marker wires. This can lead to deviations of several millimetres between real and assumed dwell positions for treatment planning with simplified source path models. The aim of this study was to test video-...
Purpose The aim of this study is to describe a phantom designed for independent examination of a source position in brachytherapy that is suitable for inclusion in an external auditing program. Material and methods We developed a phantom that has a special design and a simple mechanism, capable of firmly fixing a radiochromic film and tandem-ovoid applicators to assess discrepancies in source...
The purpose of this report is to evaluate the geometric movement (relative to the bony pelvis) and dose variation of brachytherapy reference points in the same patient at repeated high-dose rate (HDR) intracavitary implants. A study was also concluded to find the variation in treatment volume from repeated fractions. Twenty-five consecutive cervical cancer patients (all stages) treated with ext...
Implementation of Image-guided adaptive brachytherapy (IGABT) in India and other developing countries is a major challenge due to the resources, expertise and financial constraints. The basis of this thesis was to address various issues related to transition and successful implementation of IGABT in clinical routine.[1] Tata Memorial Hospital (TMH), Mumbai has a long tradition of being active i...
IntroductionSerous endometrial intraepithelial carcinoma (SEIC) is a rare diagnosis, defined as an lesion with cells identical to serous type carcinoma. SEIC considered be potentially metastatic, however clear and robust data on prognosis are lacking, leading variability in clinical management. Objective: The aim establish the opinion of gynecologists optimal management patients SEIC. Methods: ...
