Assessment of the survival rate of patients with malignant neoplasms of the choroid in the Orenburg region

The purpose of the work is to analyze the impact of various factors on the survival of patients with malignant neoplasms of the choroid. Materials and methods. A retrospective analysis of the databases of the V.I. Voynov Orenburg State Clinical Eye Hospital for 2013–2022 was carried out. Among the cases of complaints about malignant neoplasms of the vascular membrane (ICD code C69.3), cases with uveal melanoma were selected. The survival rate of the patients was calculated. Results. Among the completed cases, the most common cause of death was malignant neoplasm of the vascular membrane. The study showed that age and gender do not affect survival rates (p ˃ 0,05). However, among the examined cases, survival was higher among urban residents compared with rural residents (p = 0.019). Also, higher survival rates were demonstrated in the group of patients who underwent laser treatment (p = 0.017). In addition, survival is higher among patients treated at stage 1 of the disease than among patients treated at stage 4 of the disease (p = 0.00140). Conclusions. The life prognosis of patients with malignant neoplasms of the choroid is favorably influenced by living in an urban area, treating the disease at an early stage using organ-preserving techniques.
