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: Toxicity assessment is done by comparing HDR brachytherapy with ICRU point doses. D2cc doses of OAR in slightly more than Objectives:The primary objective volumetric dose and toxicity comparison between brachytherapy. Materials Methods: It a prospective comparative study. The total number patients enrolled the study 20. After obtaining informed consent, then were All diagnosed H.P.E...

BACKGROUND We reviewed the outcomes of oropharyngeal squamous cell carcinoma treated with external beam radiation and interstitial brachytherapy. METHODS Ninety patients with squamous cell carcinoma of the oropharynx were treated with interstitial brachytherapy at the University of Utah between 1984 and 2001. Seventy-two patients received external beam radiotherapy (EBRT) followed by brachyth...

IMPORTANCE Various treatment options exist for nonmelanoma skin cancer (NMSC), including topical agents, surgery, or definitive or adjuvant radiation therapy. Recently, electronic surface brachytherapy (ESB) has been described as a noninvasive option for NMSC. We report a case of local recurrence of basal cell carcinoma (BCC) and ocular complications following ESB to the lower eyelid. OBSERVA...

OBJECTIVE The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. METHODS Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information...

BACKGROUND A modified form of high dose rate (HDR) brachytherapy has been developed called Axxent Electronic Brachytherapy (EBT). EBT uses a kilovolt X-ray source and does not require treatment in a shielded vault or a HDR afterloader unit. A multi-center clinical study was carried out to evaluate the success of treatment delivery, safety and toxicity of EBT in patients with endometrial cancer....
