Dosimetric evaluation of a novel high dose rate (HDR) intraluminal / interstitial brachytherapy applicator for gastrointestinal and bladder cancers
High dose rate (HDR) brachytherapy is one of the accepted treatment modalities in gastro-intestinal tract and bladder carcinomas. Considering the shortcoming of contact brachytherapy routinely used in gastrointestinal tract in treatment of big tumors or invasive method of bladder treatment, an intraluminal applicator with the capability of insertion into the tumor depth seems to be useful. This...
متن کاملDosimetric equivalence of nonstandard HDR brachytherapy catheter patterns.
PURPOSE To determine whether alternative high dose rate prostate brachytherapy catheter patterns can result in similar or improved dose distributions while providing better access and reducing trauma. MATERIALS AND METHODS Standard prostate cancer high dose rate brachytherapy uses a regular grid of parallel needle positions to guide the catheter insertion. This geometry does not easily allow ...
متن کاملVital role of volume and number of needles in HDR brachytherapy (HDR-BT) of prostate cancer
PURPOSE The quality of HDR-BT of prostate cancer depends on operator skills, anatomy, prostate volume and relation to surrounding tissues as well as previous diseases and treatments of a patient. There is a rare data available concerning the minimum number of needles and its influence on dose distribution, side effects and long-term outcome. The study is to determine the minimal prostate volume...
متن کاملDosimetric optimization of a conical breast brachytherapy applicator for improved skin dose sparing.
PURPOSE Both the AccuBoost D-shaped and round applicators have been dosimetrically characterized and clinically used to treat patients with breast cancer. While the round applicators provide conformal dose coverage, under certain clinical circumstances the breast skin dose may be higher than preferred. The purpose of this study was to modify the round applicators to minimize skin dose while not...
متن کاملHDR brachytherapy (HDR–BT) combined with stent placement in palliative treatment of esophageal cancer
PURPOSE In the study we present the initial results of palliative treatment using combined methods of HDR-BT and stent insertion in patients with advanced esophagus cancer. MATERIAL AND METHODS Fifty patients were treated in the Great Poland Cancer Center using HDR-BT between June 2001 and December 2005 and they were enrolled into the study. All patients underwent endoscopic insertion of self...
