PURPOSE In an effort to shed light on the continuing debate over the best treatment options for patients with localized prostate cancer, we present a retrospective review of patients from a single group community urology practice. METHODS AND MATERIALS Data from 1707 patients were reviewed. These patients, with T1 or T2 adenocarcinoma of the prostate, were treated from 1992 to 2004 with eithe...

This research intends to unveil the presence of radioisotopes in soil some mining sites Nasarawa state using thermos-scientific interceptor (IdentiFINDER). The work aimed at detecting presence, types and trust level radioisotopes. result showed that, 103Pd 125I were found 57% total points percentage abundance detector reached 50-65% indicating those are likely area, 109Cd was 15% areas. for sho...

PURPOSE A phase 2 protocol was designed and implemented to assess the toxicity and efficacy of hypofractionated image guided intensity modulated radiation therapy (IG-IMRT) combined with low-dose rate 103Pd prostate seed implant for treatment of localized intermediate- and high-risk adenocarcinoma of the prostate. METHODS AND MATERIALS This is a report of an interim analysis on 24 patients en...

PURPOSE To evaluate the patterns of regression of iris melanoma after treatment with palladium-103 (103Pd) plaque brachytherapy. DESIGN Retrospective, nonrandomized, interventional case series. PARTICIPANTS Fifty patients with primary malignant melanoma of the iris. METHODS Palladium-103 plaque brachytherapy. MAIN OUTCOME MEASURES Changes in tumor size, pigmentation, and vascularity; in...

Introduction: Clinical application of encapsulated radioactive brachytherapy sources has a major role in cancer treatment. In the present research, the effects of different tissue densities on the dose distribution of a 103Pd brachytherapy source in a spherical phantom of 50 cm radius have been studied. Material and Methods: As is well known, absorbed dose in tissue depends to its density, but ...

Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...
