- W1992620005 abstract "To present the experience of King Khaled Eye Specialist Hospital (KKESH) with uveal melanoma over the last two decades in a fashion similar to the result of the Collaborative Ocular Melanoma Study (COMS). Retrospective, non-comparative, interventional, case series. All patients were diagnosed with uveal melanoma at the King Khaled Eye Specialist Hospital (KKESH), Riyadh, Saudi Arabia from June 1983 to July 2005 and met the inclusion criteria of the COMS. A medical record review of clinical history, imaging studies, surgical procedures and treatment outcome was performed. Forty patients (24 males and 16 females) with uveal melanoma (average age 50 years; range 24–77 years) were included in the study; 28 (70%) were of Saudi Arabian descent and the remaining 12 (30%) patients were from neighboring Arab countries. Decreased vision was the main presenting complaint of 29 (72.5%) patients; the duration of this symptom was 3 months or more in 27 (67.5%) patients. The apical height of the tumor was 10 mm or more in nine (22.5%) of the affected eyes and the largest basal dimension was more than 16 mm in nine (22.5%) of the affected eyes. The posterior border of the tumor was 1–2 mm from the optic disc in three (7.5%) affected eyes. Primary enucleation was performed for 33 (82.5%) eyes, episcleral radiation plaque therapy for six (15%) of the eyes and endo resection of the uveal melanoma in one (2.5%) eye. Adjunct external beam radiation therapy was performed in two (5%) orbits for extrascleral extension. The histopathological diagnosis was available for 34 (84%) eyes in which surgery had been performed (33 patients underwent primary enucleation and one patient underwent endo resection of the uveal melanoma); 24 (70.6%) eyes had spindle cell and the remaining 10 (29.4%) had epithelioid or mixed cell types. Evidence of extraocular tumor extension was found in three eyes. The average follow-up was 33.7 months with a median of 19 months (range 0.5 months to 10 years). Two (5%) patients developed metastasis after 2 years and 5 years from the initial treatment of large and medium-sized uveal melanomas, respectively. Individuals of Saudi Arabian ancestry appear to have a low incidence of uveal melanoma. Further studies are required to estimate the true incidence of uveal melanoma in the larger Arab population. Early detection is essential for improving the patient outcomes. Regular communication between the tertiary care eye centers and the local ophthalmic care providers is required to enhance the understanding about uveal melanoma behavior in Arab population." @default.
