Dose gradient impact on equivalent dose at 2 Gy for high dose rate interstitial brachytherapy
PURPOSE To evaluate a new calculation model estimating the equivalent dose at 2 Gy (EQD2) taking into account dose gradient in high dose rate interstitial brachytherapy (HDRIB). MATERIAL AND METHODS Forty dose-volume histograms (DVHs) of breast (20 pts) and prostate (20 pts) cancer dose distributions were reviewed. Physical prescribed doses (PPD) were 34 Gy (10f/5d) and 18 Gy (6f/2d) for brea...
متن کاملHigh-dose-rate interstitial brachytherapy for gynecologic malignancies.
PURPOSE The study aimed to assess the outcome of locally advanced cervical and vaginal cancer treated with high-dose-rate interstitial brachytherapy (HDRB). METHODS AND MATERIALS Between 1998 and 2004, 16 previously unirradiated patients with locally advanced cervical and vaginal cancer not suitable for intracavitary brachytherapy because of distorted anatomy or extensive vaginal disease were...
متن کاملHigh-dose-rate interstitial brachytherapy for female peri-urethral cancer.
PURPOSE Peri-urethral cancer (PUC) in females is a rare malignancy. Surgery is not usually contemplated due to associated morbidity. Radiation therapy (RT) can be employed in the form of interstitial brachytherapy (IBT) alone for early lesions, and external beam radiation therapy (EBRT) with or without IBT for advanced lesions. We report our first experience in the literature to evaluate the ro...
متن کاملApplicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film
Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...
متن کاملFractionated High-Dose-Rate Brachytherapy
Purpose: A growing body of data suggests that local control in nasopharyngeal cancer (NPC) is related to the radiation dose administered. We conducted a singleinstitution study of high-dose radiotherapy (RT), which incorporated high-dose-rate (HDR) brachytherapy (BT). These results were analyzed together with data obtained from controls who did not receive BT. Patients and Methods: The BT group...
