Abstract

Background: In Iran, cancers are known as the second leading cause of death, among which respiratory system cancers are particularly important because lung cancer is the second most common cause of death in this country. This study aimed to estimate the crude and age-standardized mortality and its trends during 9 years in the northern city of Iran, Babol.
Methods: In this cross-sectional study, all the recorded deaths due to respiratory system cancers in Babol during the years 2013-2021 on the Classification of Causes of Deaths and Death Registration System of Babol University of Medical Sciences were taken into consideration, and the population estimate was based on the latest census. Finally, the crude and age-standardized rates of mortality and trends of cancer incidents were calculated.
Results: In general, 393 deaths with an overall mean age of 67.8±3.9 years have happened due to respiratory system cancers. The crude and standardized rates of respiratory system cancers increased from 6.5 and 5.5 per hundred thousand people in 2013 to 9.1 and 7.8 per hundred thousand people in 2021, respectively. With each decade in age, their trends increased significantly in men (p=0.024) and remained constant in women (p=0.262). In examining the trend of respiratory system cancers, we found an increasing trend for lung cancer and a constant trend for larynx and oropharynx cancers. There was also a decreasing trend for hypopharyngeal cancer.
Conclusions: The age-standardized rate and trend of respiratory system cancers are increasing. Therefore, it is important to prevent their prevalence by reducing the risk factors and increasing the general awareness of risks and timely diagnosis.
