Background . Prostate cancer (PCa) is one of the most common malignant diseases in men worldwide, with over 1.1 million cases PCa reported annually. In Russian Federation, proportion patients stage I—II from 2008 to 2018 increased 37.6 % 56 %, which turn allows more and perform radical treatment methods. However, it should be noted that number both recurrent after radiation therapy (external be...

Introduction: Long-term teletherapy program is not suitable for old and working patients and those living in areas where little access to primary health care is available. Accelerated partial breast irradiation (APBI) using high dose rate (HDR) brachytherapy is an appropriate alternative for these patients due to its limited number of fractions. The AccuBoost is a system for delivering APBI. Th...

Purpose Brachytherapy (BT) deals with high gradient internal dose irradiation made up of a complex system where the source is placed nearby tumor to destroy cancerous cells. A primary concern clinical safety in BT quality assurance ensure best matches between delivered and prescribed doses targeting small volume tumors sparing surrounding healthy tissues. Hence, purpose this study evaluate perf...

BACKGROUND To assess brachytherapy catheter positioning accuracy and to evaluate the effects of prolonged irradiation time on the tolerance dose of normal liver parenchyma following single-fraction irradiation with 192Ir. MATERIALS AND METHODS Fifty patients with 76 malignant liver tumors treated by computed tomography (CT)-guided high-dose-rate brachytherapy (HDR-BT) were included in the stu...

The aim of the present study was to estimate the wall effect of the self-made spherical graphite-walled cavity chamber with the Monte Carlo method for establishing the air-kerma primary standard of high-dose-rate (HDR) ¹⁹²Ir brachytherapy sources at the Institute of Nuclear Energy Research (INER, Taiwan). The Monte Carlo method established in this paper was also employed to respectively simulat...

The aim of this work is to evaluate the performance of a commercial brachytherapy treatment planning system (TPS) with TG-43 Vendors Input Data (VID), analyze possible discrepancies with respect to a proper reference source and its implications for standard treatments, and judge the effectiveness of certain widespread recommended quality controls to find potential errors related with the interp...

Introduction: Brachytherapy, especially using manually after loaded Iridium-192 and Cobalt-60, can be applied as a sole treatment, as a treatment complementary to surgery, and as a local boost in combination with EBRT. The use of HDR brachytherapy catheters incorporated in removable dental molds allows repeated, highly reproducible, fractionated outpatient brachytherapy of supe...

Purpose To evaluate if the dose equivalent to 2 Gy per fraction (EQD2)(α/β=3Gy) at 0.1 cm3, 1 cm3, and 2 cm3 of vagina in vaginal-cuff-brachytherapy (VBT) (high-dose-rate [HDR] 192Ir-source) ± external-beam-irradiation (EBRT) is associated with toxicity in post-operative endometrial carcinoma (P-EC). Material and methods From June 2014 till November 2015, 67 consecutive P-EC patients underwen...
