Radiation hazards during cobalt 60 plaque therapy for choroidal melanoma

Multicurie Cobalt 60 Units for Radiation Therapy.

Subfoveal choroidal melanoma: pretreatment characteristics and response to plaque radiation therapy.

OBJECTIVE To evaluate the clinical presentation, tumor characteristics, and response to palladium 103 plaque radiation therapy for subfoveal choroidal melanomas. METHODS Retrospective case series of 50 patients diagnosed as having subfoveal melanoma and treated with plaque brachytherapy. Patients underwent evaluation for tumor characteristics, visual acuity, radiation damage, local tumor cont...

Microwave plaque thermoradiotherapy for choroidal melanoma.

Microwave thermoradiotherapy was used as a primary treatment for 44 patients with choroidal melanoma. An episcleral dish-shaped microwave antenna was placed beneath the tumour at the time of plaque brachytherapy. While temperatures were measured at the sclera, the tumour's apex was targeted to receive a minimum of 42 degrees C for 45 minutes. In addition, the patients received full or reduced d...

Complications from Plaque versus Proton Beam Therapy for Choroidal Melanoma: A Qualitative Systematic Review

Plaque brachytherapy has been a mainstay of treatment for choroidal melanoma to achieve intraocular tumor control. The most common radioisotopes used for treating smaller sized tumors are Iodine-125 in North America and Ruthenium-106 in Europe. Proton beam radiotherapy is available at a few centers and may also be used to achieve local tumor control. Both plaque and proton beam therapy are know...

CLINICAL SCIENCES Palladium 103 (Pd) Plaque Radiation Therapy for Circumscribed Choroidal Hemangioma With Retinal Detachment

Methods: One course of Pd ophthalmic plaque radiotherapy was used in each of 5 patients with circumscribed choroidal hemangioma who had progressive loss of vision due to subretinal exudation. A mean apex dose of 2900 cGy (2900 rad) was delivered. Functional tests of outcome included best-corrected visual acuity. Anatomic results included changes in tumor height and subretinal fluid documented b...
