Introduction In this study, we aimed to calculate dose enhancement factor (DEF) for gold (Au) and iron (Fe) nanoparticles (NPs) in brachytherapy and teletherapy, using Monte Carlo (MC) method. Materials and Methods In this study, a new algorithm was introduced to calculate dose enhancement by AuNPs and FeNPs for Iridium-192 (Ir-192) brachytherapy and Cobalt-60 (Co-60) teletherapy sources, using...
Background and purpose: Dose calculations in trachea HDR brachytherapy treatment planning systems are greatly based on TG-43 protocol in which, all materials including air inside trachea are treated the same as water. The aim of this study was to survey the effect of air on dose calculations of Flexiplan treatment planning system in trachea HDR brachytherapy. Materials and methods: To ev...
Introduction: Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated, are placed as close as possible to the tumor site or inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule to create optimal treatment plant. In this way, dosimetric parameters are...
Traditional brachytherapy refers to the placement of radioactive sources on or inside the cancer tissues. Based on the type of sources, brachytherapy can be classified as radionuclide and electronic brachytherapy. Electronic brachytherapy uses miniaturized X-ray sources instead of radionuclides to deliver high doses of radiation. The advantages of electronic brachytherapy include low dose to or...
The theme of the conference was " Brachytherapy – an Immortal Art ". The pre-conference workshop (26 th August 2016) was conducted at Cancer Institute (WIA), Adyar, Chennai. The workshop included live hands-on demonstration of interstitial brachyther-apy procedures for oropharyngeal cancer (base of tongue), and intra-operative brachytherapy for soft tissue sarcoma of gluteal region. The procedu...
PURPOSE To report the treatment effect of interstitial brachytherapy for chest wall locoregional recurrence of breast cancer. MATERIAL AND METHODS This 44-year-old female presented with chest wall recurrence seven years after modified radical mastectomy for stage II breast cancer. Despite external beam radiation and chemotherapy, the lesion expanded as 5.3 × 5.1 × 3.0 cm(3), and 8.0 × 5.1 × 4...
Purpose To report an innovative technique of interstitial brachytherapy developed for treatment of orbital soft tissue tumors. Material and methods A 4-month-old child diagnosed with rhabdomyosarcoma of orbit was treated with multiagent chemotherapy (CTh) and brachytherapy. Pre-planning computed tomography (CT) images were obtained and clinical target volume (CTV) was defined using the pre-tr...
Intracavitary brachytherapy treatment has a very important role in patients with locally advanced cervical cancer. Brachytherapy is painful procedure, especially whom opening cannot be achieved, and requires analgesia immobilization. The American Association (ABA) recommends the use of conscious sedation as much possible intracavitary high-doserate (HDR) applications diagnosed In this review, w...
PURPOSE Permanent low-dose-rate (LDR-BT) and temporary high-dose-rate (HDR-BT) brachytherapy are competitive techniques for clinically localized prostate radiotherapy. Although a randomized trial will likely never to be conducted comparing these two forms of brachytherapy, a comparative analysis proves useful in understanding some of their intrinsic differences, several of which could be exploi...
PURPOSE We performed a survey amongst attendees of the 4(th) Annual Meeting of Indian Brachytherapy Society to study the patterns of brachytherapy practice and attitude towards brachytherapy use. MATERIAL AND METHODS A 19-point questionnaire was designed and e-mailed to the attendees immediately after the conference. Descriptive analysis of the responses were done and satisfaction index was u...
