Abstract: (20 Views)
Introduction: Bladder cancer is one of the most common malignant diseases of the urinary tract, which is caused by various factors such as tobacco use, exposure to carcinogens in the workplace, and genetic factors. A comprehensive understanding of the epidemiology of this disease is significantly effective in health and preventive planning. This study aimed to investigate the demographic characteristics, incidence, and geographical distribution of bladder cancer in Mazandaran province between 2015 and 2019.
Materials and Methods: This cross-sectional study was conducted on 1,370 patients with bladder cancer using data from the provincial cancer registry. The data included demographic characteristics such as gender, age, place of residence, year of diagnosis, and type of diagnosis. SPSS 20 software was used for statistical analysis and T test, and Chi-square tests were used to compare the differences between variables.
Results: The results showed that 80.1% of the patients were male and 19.9% were female, and the mean age of the patients was 66.92 years with an age range of 1 to 98 years. The highest number of patients was seen in the age group over 60 years. The age standardized incidence rate of bladder cancer in Mazandaran province (ASR) showed that this value was 8.1 in 2015 and 2016, and then increased in 2017 and reached 9.1. In 2018, it decreased slightly and decreased to 8.5 and returned to the same number of 9.1 in 2019. The highest number of cases was recorded in 2019 with 297 patients. In terms of geographical distribution, the highest number of cases was in the cities of Sari, Babol and Amol. Statistical tests did not show a significant difference in age based on gender (p=0.215) and place of residence (p=0.255). About 83.4% of the cases were confirmed through pathological diagnosis.
Conclusion: Bladder cancer in Mazandaran province is more common in men and older people. The increasing trend of this disease requires serious preventive measures. Considering the concentration of cases in some regions, it is suggested that surveillance programs and increasing public awareness be implemented regionally.
