[2 years' experience with treatment of uveal melanoma using the Leksell gamma knife].
In the last years, the therapy of ocular melanoma with Leksell's gamma-knife was indicated at several clinics in Prague. It referred to bulky tumors and to unfavourably localized tumors so that only enucleation of the eyeball was the only alternative in our conditions. The results of the treatment of 11 patients have been evaluated in this article. Some other patients treated with this method have not been included in this sample for various reasons (short-term follow-up, combination of radiotherapy with gamma-knife with other therapeutic modality etc.) Gradual decrease in tumor size developed in 10 patients during follow-up. The decrease in tumor size has been observed on repeated ultrasound examinations and magnetic resonance imaging. The growth of tumor was reappeared in one patient, which led to the necessity of enucleation of the eyeball. The complications in other patients were numerous but not serious to such extent that would lead to enucleation. Marked deterioration in visual acuity connected with the treatment occurred in 6 patients. The results achieved by this method are comparable with those achieved by other therapeutic modalities and with the results from other clinics employing gamma-knife for the treatment of uveal melanoma. The results lead to the conclusion that this is an effective method of treatment of uveal melanoma and that this method is able to go through further development, especially in combination with other therapeutic modalities.
