Preliminary study of prevalence for bladder cancer in Isfahan Province, Iran
Objectives: To clarify period prevalence (PP), incidence rate (Ir), and reported mortality for patients with bladder cancer (BC) in Isfahan Province/Iran, as BC is the most common cancer of the urinary tract in Iran and other parts of the world. Patients and methods: Data from 21 March 2011 to 3 Mar...

| Sumario: | Objectives: To clarify period prevalence (PP), incidence rate (Ir), and reported mortality for patients with bladder cancer (BC) in Isfahan Province/Iran, as BC is the most common cancer of the urinary tract in Iran and other parts of the world.
Patients and methods: Data from 21 March 2011 to 3 March 2015 was obtained from the Isfahan Cancer Registry. BC was distinguished by the related established topography code (C67). Ir and PP were calculated and expressed per 100 000 persons.
Results: In all, 279 females and 1376 males were identified. For the total population the PP was calculated as 33.2. This value corresponded to a PP of 54.4 for males and 11.4 for females (P < 0.001). Histologically, 63% of patients had invasive BC. Irs versus mortality rates were calculated for each year, i.e. 2011–2012, 2012–2013, 2013–2014, and 2014–2015, as 7.7 vs 0.56, 8.1 vs 0.74, 7.4 vs 0.98, and 9.9 vs 0.84, respectively. The mean (SD, range) age of the patients was 65.2 (13.9, 3–100) years. In relation to the age of the study population, BC occurred in 12% of patients aged <50 years and in 15% of those aged ≥80 years.
Conclusion: The PP for BC in the male population was 4.8-times higher than females. There was a 28.6% increase in the Ir over the study period. Further study concerning environmental exposure, genetic factors, job-related exposure to various chemical carcinogens, and geographical distribution in Isfahan and its’ rural provinces would seem to be valuable. |
