purpose : to assess the results of brachytherapy in patients with recurrent or incomplete excised conjunctival squamous cell carcinoma (scc) and malignant melanoma. methods : three patients underwent brachytherapy of one eye and one patient underwent brachytherapy of both eyes with ruthenium-106 (ru-106) plaques, all of them had a history of incomplete resection or recurrence of the tumor after...
purpose: to evaluate the effect of radiation with ruthenium-106 (ru-106) plaques in the control of retinal vasoproliferative tumors methods: this study is a retrospective, interventional nonrandomized case series. seven eyes of seven patients (four males and three females) with retinal vasoproliferative tumors were enrolled. the eyes were treated by ru-106 plaques with mean apex dose of 39 gy (...
PURPOSE The Collaborative Ocular Melanoma Study (COMS) established iodine-125 (I-125) plaque brachytherapy for eye preserving treatment of medium-sized choroidal melanomas in the United States. Eye Physics I-125 plaque treatment modeled with Plaque Simulator (PS) software yields similar results to COMS. Herein, we report results from a series of 15 patients treated with ruthenium-106 (Ru-106) p...
Background: Brachytherapy is the most commonly used conservative treatment for the uveal melanoma. The aim of this study was to evaluate therapeutic results of Ruthenium-106 plaque brachytherapy in the management of localized uveal melanoma cases. Methods: We reviewed retrospectively the clinical records of all patients treated in our department for an uveal melanoma, undergoing Ruthenium-106 p...
Understanding the dose distribution of beta-emitting eye plaques respect to the location of tumor is of importance. In this study, the geometry of CCB, COB and CIB plaques (BEBIG manufacturer) for specific eye tumors were simulated and the effects of different coated radionuclides and plaque materials were investigated, by Geant4 simulation toolkit. For validation, a dosimetric investigation wa...
Diffuse choroidal hemangiomas associated with Sturge-Weber syndrome (SWS) are classically treated with external beam radiotherapy (EBR), but there are a few reports usually of single cases indicating the usefulness of plaque therapy. We present our observations on two cases of diffuse choroidal hemangiomas with exudative retinal detachment associated with SWS treated with Ruthenium-106 plaque t...
PURPOSE To report on conservation of visual acuity after Ruthenium(106) (Ru-106) brachytherapy of choroidal melanoma. METHODS AND MATERIALS This study was a noncomparative interventional case series of 458 patients with choroidal melanoma treated at a single center between January 1993 and December 2001. The intervention consisted of Ru-106 brachytherapy delivering minimum scleral and apex do...
