Optimal bladder filling during high-dose-rate intracavitary brachytherapy for cervical cancer: a dosimetric study
PURPOSE The aim of this study is to compare 3D dose volume histogram (DVH) parameters of bladder and other organs at risk with different bladder filling protocol during high-dose-rate intracavitary brachytherapy (HDR-ICBT) in cervical cancer, and to find optimized bladder volume. MATERIAL AND METHODS This dosimetric study was completed with 21 patients who underwent HDR-ICBT with computed tom...
متن کاملBiological effective doses in the intracavitary high dose rate brachytherapy of cervical cancer
PURPOSE The aim of this study is to evaluate the decrease of biological equivalent dose and its correlation with local/loco-regional control of tumour in the treatment of cervical cancer when the strength of the Ir-192 high dose rate (HDR) brachytherapy (BT) source is reduced to single, double and triple half life in relation to original strength of 10 Ci (∼ 4.081 cGy x m(2) x h(-1)). MATERIA...
متن کاملOptimum organ volume ranges for organs at risk dose in cervical cancer intracavitary brachytherapy
PURPOSE To analyze the optimum organ filling point for organs at risk (OARs) dose in cervical cancer high-dose-rate (HDR) brachytherapy. MATERIAL AND METHODS In a retrospective study, 32 locally advanced cervical cancer patients (97 insertions) who were treated with 3D conformal external beam radiation therapy (EBRT) and concurrent chemotherapy during 2010-2013 were included. Rotterdam HDR ta...
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 کاملPositional variation of applicators during low dose rate intracavitary brachytherapy for cervical cancer: a prospective study
PURPOSE In order to know the effect of variation in position of applicators to the dose received by the tumor volume, critical organs such as rectum and bladder and the correlation of variation on the clinical outcome. MATERIAL AND METHODS 36 patients with histologically proven cervical cancer, undergoing intracavitary brachytherapy (ICBT) from October 2005 to December 2006 were the subjects ...
