To analyze the clinical characteristics and survival of Chinese uveal melanoma (UM) patients. It was a retrospective case series study. Clinical data and demography characteristics of 1 166 UM patients who were diagnosed in Beijing Tongren Hospital from January 2004 to January 2020 were collected. The disease was followed up after informed consent was obtained. Kaplan-Meier plots were used to visualize survival outcomes, and the different risk groups were compared using the Log-rank test. The multivariate Cox proportional hazards model was used to select independent prognostic risk factors. A total of 1 166 individuals (598 men, 568 women) were included in this study. The average age was (47.6±12.2) years. Median follow-up time was 38 months. Treatment included episcleral brachytherapy in 881 (75.6%) patients, local tumor resection in 38 (3.2%) patients, laser therapy in 115 (9.9%) patients and primary enucleation in 119 (10.2%) patients. In 120 patients out of the 881 patients with primary brachytherapy, enucleation was performed due to an increasing tumor size or uncontrolled neovascular glaucoma. The Kaplan-Meier survival analysis showed the 5-and 10-year metastasis rates were 18.5% and 26.8%, and the melanoma-related mortality rates were 13.6% and 22.2%, respectively. The Log-rank test showed that patient age (²=5.01) and gender (²=7.19), as well as tumor grade (²=49.11), shape (²=34.73), location (²=18.60), pathological type (²=8.07), presence of subretinal fluid (²=15.71) and ciliary body involvement (²=19.72) were factors influencing patient prognoses (all <0.05). In the multivariate Cox analysis, the T2, T3, T4 tumors (compared with the T1 tumor, =4.41, 6.82, 10.49), subretinal fluid (=1.98), ciliary body involvement (=1.79), being male (=1.53) and advanced age (greater than 53 years old) (1.83) were independent risk factors for poor prognoses (all <0.05). UM occurs at a significantly earlier age and non-pigmented tumors represent smaller proportion in Chinese patients. Higher T-stage, presence of subretinal fluid, ciliary body involvement, advanced age, and being male are independent risk factors for poor outcomes.
