National cancer mortality-to-incidence ratio (MIR) in Iran (2005-2014)

Abstract

Background: Cancer is the first cause of death followed by ischemic heart disease (IHD) and stroke, worldwide, with increasing 19.5% years of life lost (YLL) due to cancer from 2007 to 2017. The cancer burden is steadily increased with decreasing 4.4% death rate from 2007-2017. The incidence rate of cancer is twice to 3 times higher in developed countries with low mortality due to care regarding developing countries. Objectives: Here, we report the 10 years’ incidence and mortality of malignancies in Iran with different patterns compared to the other parts of the world. Methods: Data of national cancer registry system from 2005 to 2014 were analyzed in order to find out the trend of age standardized incidence rate (ASIR)/age standardized mortality rate (ASMR)/ mortality to incidence ratio (MIR) in both sexes in Iranian population. Results: Growing trend in ASIR for both sexes in all of the cancers were seen. ASMR decreased from 2005 to 2014 in both sexes with higher rate in males. MIR decreased by half in 2014 compared to 2005 regarding the increase of cancer in Iran. Conclusions: In Iran, the incidence of cancer is increasing due to aging people and death is decreasing due to the good care of patient. So, it is a good sample of developing country, which is comparable with the developed ones.
