Low Dose-Rate Interstitial Brachytherapy in Soft Tissue Sarcomas
Purpose. To assess the effectiveness of Ir-192 interstitial brachytherapy as an adjunct to wide local excision as a functionsaving strategy for soft tissue sarcomas.Subjects and methods. From September 1993 to April 1998, 20 consecutive patients diagnosed with soft tissue sarcomas were treated with a combination of wide local excision and interstitial brachytherapy. In 16 patients brachytherapy...
متن کاملDosimetric comparison of various optimization techniques for high dose rate brachytherapy of interstitial cervix implants
HDR brachytherapy treatment planning often involves optimization methods to calculate the dwell times and dwell positions of the radioactive source along specified afterloading catheters. The purpose of this study is to compare the dose distribution obtained with geometric optimization (GO) and volume optimization (VO) combined with isodose reshaping. This is a retrospective study of 10 cervix ...
متن کاملHigh-dose-rate brachytherapy for soft tissue sarcoma in children: a single institution experience
PURPOSE To report our experience treating soft tissue sarcoma (STS) with high dose rate brachytherapy alone (HBRT) or in combination with external beam radiotherapy (EBRT) in pediatric patients. METHODS AND MATERIALS Eighteen patients, median age 11 years (range 2 - 16 years) with grade 2-3 STS were treated with HBRT using Ir-192 in a interstitial (n = 14) or intracavitary implant (n = 4). Ei...
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...
