The Impact of Residual Geometric Inaccuracies on Normal Organ Doses in Image Guided-Radiation Therapy of Prostate Cancer Using On-Board Kilovoltage Cone-Beam Computed Tomography
Introduction: The aim of this retrospective study was to evaluate the variations in delivered dose to the bladder, rectum, and femoral heads of prostate cancer patients during a course of treatment by image-guided radiation therapy (IGRT). Materials and Methods: Overall, 15 patients with prostate cancer were selected and. Each week, for each patient five consecutive cone beam computed tomograph...

متن کاملAcute gastrointestinal and genitourinary toxicity of image-guided intensity modulated radiation therapy for prostate cancer using a daily water-filled endorectal balloon
BACKGROUND Our purpose was to report acute gastrointestinal (GI) and genitourinary (GU) toxicity rates for prostate cancer patients undergoing image-guided intensity modulated radiation therapy (IG-IMRT) with a daily endorectal water-filled balloon (ERBH2O), and assess associations with planning parameters and pretreatment clinical characteristics. METHODS The first 100 patients undergoing pr...
متن کاملDosimetric and deformation effects of image-guided interventions during stereotactic body radiation therapy of the prostate using an endorectal balloon.
PURPOSE During stereotactic body radiation therapy (SBRT) for the treatment of prostate cancer, an inflatable endorectal balloon (ERB) may be used to reduce motion of the target and reduce the dose to the posterior rectal wall. This work assessed the dosimetric impact of manual interventions on ERB position in patients receiving prostate SBRT and investigated the impact of ERB interventions on ...
متن کاملThe Anticoagulated Atrial Fibrillation Patient Who Requires "Curative" Therapy for Prostate Carcinoma: a Bleeding Conundrum.
With the aging of the population, the incidence of both prostate carcinoma (PCa) and atrial fibrillation (AF) has increased. Options for “curative therapy” PCa now include surgery, external beam radiation (EBT), and radioactive seed implantation (RSI). The latter two approaches, especially EBT, can produce radiation proctitis (RP) with rectal bleeding (RB). This poses an issue for anticoagulati...
