The morbidity and survival rates of patients with bladder cancer, depending on various causes, have been studied by many authors. However, there are a limited number of studies using the analysis of patient survival at the population level. Patient survival information can optimize the therapy and prevention of bladder cancer. The results of survival of patients with this disease in different gender and age categories should be studied more actively. The aim of the study was to study the observed and relative survival of patients with bladder cancer in gender-age groups in the Samara region for the period 2010-2012.The materials of the study were the primary records of 1059 patients for the period from 2010 to 2012. To obtain the results of survival, an actuarial method was used. To assess the reliability of the comparison of the obtained indicators, the Z and p criteria were used. In the course of the study, when assessing the 1-year and 5-year cumulative survival of patients with bladder cancer, there were lower rates of observed survival compared with the relative one.There were no statistically significant differences in the 1-year and 5-year relative survival rates for men and women. The 5-year observed survival rate for women was significantly higher than for men. With increasing age, survival rate for bladder cancer declines. The indicators of 1-year and 5-year relative survival of patients aged 50-59 years were significantly higher than the corresponding indicators of 60-69 years old. In the age group of 40-49-year-olds, there was a significantly higher relative survival rate of women compared with men.
