Stereotactic radiotherapy in the treatment of ocular melanoma: A noninvasive eye fixation aid and tracking system
Ocular melanoma is frequently treated using brachytherapy implants (such as 125I and 60Co plaques or 184Ta wire), surgery, or external beam radiotherapy using small 60Co beams, high energy x-rays, or proton therapy. The last technique, though very expensive, provides improved dose distributions and dose localizations in the treatment of tumours adjacent to critical normal tissues. The technique...
متن کاملReproducibility of a Noninvasive System for Eye Positioning and Monitoring in Stereotactic Radiotherapy of Ocular Melanoma
PURPOSE Our preferred treatment for juxtapapillary choroidal melanoma is stereotactic radiotherapy. We aim to describe our immobilization system and quantify its reproducibility. MATERIALS AND METHODS Patients were identified in our radiosurgery database. Patients were imaged at computed tomography simulator with an in-house system which allows visual monitoring of the eye as the patient fixa...
متن کاملTechnique for Robotic Stereotactic Irradiation of Choroidal Melanoma.
Radiotherapy has a long history in the organ-sparing management of choroidal melanoma. Joining plaque radiotherapy and proton irradiation, stereotactic robotic photon irradiation is a new tool in the radiation oncologist's armamentarium for ocular tumors. The non-coplanar fields with steep dose gradients are well suited to spare uninvolved retina, anterior chamber, and the optic nerve. In our p...
متن کامل[Cytogenetic analysis of choroidal melanoma].
PURPOSE To investigate the presence of known cytogenetic alterations of choroidal melanoma in a series of patients diagnosed and treated in our Ocular Oncology Service. A review of the present literature on this topic is also presented. METHODS Microsatellite analysis (MSA) studies on loss of heterozygosity (LOH) of chromosome 3, as well as multiplex ligation prove amplification (MLPA) on chr...
متن کاملFull-thickness eye wall resection: an experimental approach for treatment of choroidal melanoma. I. Dacron-graft.
To overcome the problems of surgical treatment of tumors of the posterior segment, we have developed a ring-shaped instrument. This is sutured to the sclera or the area ivhere resection should be performed. Besides stabilizing the operative area, the two side arms of the instrument prevent collapse of the eyeball. The fidl-thickness eye wall resection i? performed with the cutting needle of the...
