RESUMO
Remote afterloading brachytherapy provides effective cancer treatment with zero personnel radiation exposure compared to conventional low dose rate systems requiring inpatient use of iridium, radium, or cesium sources. Clinical use of high dose rate brachytherapy is broadened to encompass curative treatment of cervical, endometrial, endobronchial, head and neck, esophageal, rectal, and prostatic carcinomas as well as palliation of intra-abdominal metastasis intraoperatively. Complications encountered with high dose rate sources will be compared to those of low dose rate systems commonly used in conjunction with external beam irradiation. Radiobiological effectiveness and economic benefits will be addressed to provide support for use of remote afterloading using high dose rate brachytherapy in palliative and curative treatment of selected carcinoma.
