Incidence and epidemiology of urologic cancers in North of Iran

Introduction: Urinary system malignancies are considered as one of the main public health concerns with high morbidity and mortality. These cancers have various patterns in different regions over time. This study aims to determine the incidence of these malignancies in the northern part of Iran (Mazandaran Province). Materials and Methods: This cross-sectional study carried out among patients with urologic cancers in 2014. A population-based cancer registry in Mazandaran University of Medical Sciences was the source of information. Stata software version 14 was applied for descriptive statistics and analysis. The WHO standard population was used for estimating the age and sex-standardized incidence of urologic cancers. Results: In 2014, 261 patients with cancers of the urinary system have been registered in Mazandaran Province, northern Iran. Mean, standard deviation, minimum, and maximum age of patients were 64.4, 15.6, 1, and 94, respectively. More than two-thirds of patients aged over 60 and most of them were male. The standardized incidence of cancers of the bladder, kidney, ureter, and other parts of the urinary system among men was estimated as 7.98, 1.54, 0.05, and 0.3 per 100,000, respectively. The standardized incidence of cancers of the bladder, kidney, pelvis, and ureter among women were 0.09, 0.14, 0.09, and 0.39, respectively. Conclusion: The majority of urologic cancers in the northern part of Iran are among men and those aged over 60. Moreover, bladder and renal cancers are the most common cancers in both genders.
