Background: Treatment of cervical carcinoma is routinely performed with Low Dose Rate (LDR) brachytherapy, but Brachytherapy in our department is done with Medium Dose Rate (MDR) due to the technical characteristics of the machine available here. Thus we decided to evaluate the results of this treatment in our department in a prospective study. Methods: Between March 2006 and July 2008, 140 pa...

BACKGROUND The high-dose-rate (HDR) brachytherapy might be an effective tool for palliation of dysphagia. Because of some concerns about adverse effects due to absorbed radiation dose, it is important to estimate absorbed dose in risky organs during this treatment. OBJECTIVES This study aimed to measure the absorbed dose in the parotid, thyroid, and submandibular gland, eye, trachea, spinal c...
