Article Synopsis
- The study focuses on the demographic, clinical, and management outcomes of patients with uveal melanoma at a tertiary center in Egypt over five years.
- A total of 93 patients were treated, with most tumors being choroidal, and common treatments included brachytherapy and gamma knife radiosurgery, leading to a successful globe salvage rate of 84.62%.
- The conclusion emphasizes the importance of timely referrals and proper assessments to improve treatment success and highlights the need for advanced tumor patients to consider enucleation to lower the risk of metastasis and mortality.
Article Synopsis
- * Conducted at Cairo University, it included a retrospective analysis of 7 male patients, with a significant mean age of 39.3 years, all of whom showed marked improvement in vision and tumor size after treatment.
- * Results indicated that the therapy not only reduced tumor dimensions and resolved associated complications, but also highlighted a positive safety profile, with no recurrences or significant radiation-related issues reported during a follow-up period of about 12.5 months.
