The study investigated clinical and morphologic prognostic factors affecting survival rates in patients with bone metastases of RCC. Statistical analysis was performed using Statistica 10.0 software packages (StatSoft, USA) through construction of Kaplan–Meier curves and survival tables, development of a mathematical model of survival.</p><p><bold>Results and conclusion. </bold>3-year, 5-year overall survival (OS) of patients with RCC bone metastases was 38 % (95 % confidence interval (CI) 33–44) and 23 % (95 % CI 18–28), respectively, with a median OS of 28.3 months (95 % CI 23.6–32.9) (<italic>p </italic>&lt;0.001).</p><p>In single factor analysis, ECOG (Eastern Cooperative Oncology Group) status (<italic>p </italic>&lt;0.001), Fuhrman tumor differentiation grade (<italic>p </italic>&lt;0.001), type and number of metastases (<italic>p </italic>&lt;0.001), metastases to the lung (<italic>p </italic>= 0.027), liver (<italic>p </italic>= 0.013) and lymph nodes (<italic>p </italic>&lt;0.001), IMDC (International Metastatic RCC Database Consortium) prognosis (<italic>p </italic>&lt;0.001), radiation therapy (<italic>p </italic>= 0.003) and nephrectomy (<italic>p </italic>&lt;0.001) affected OS in patients with bone metastases of RCC.

К группе промежуточного прогноза были отнесены 117 (33,4 %) больных, к группе неблагоприятного прогноза – 169 (48,3 %). В исследовании изучены клинико-морфологические факторы прогноза, влияющие на показатели выживаемости у больных ПКР с метастазами в костях.
