National and subnational pattern of cancers incidence in Islamic republic of Iran from 1990 to 2016
Providing accurate and up-to-date statistics on the incidence of illnesses, especially cancers, can make it possible for policy makers to use scientific evidence in allocating resources and distributing human resources, using guidelines to prioritize the country's research needs. A leading study aimed to estimate the incidence of cancer in Iran at national and sub-national levels from 1990 to 2016 in 18 main groups and 70 subgroups of cancers.
The incidence of various cancers for 2000-2010 is extracted and used from the cancer registry system of Iran as the main data-source of this study. Multi-variable data such as the wealth- index, years of schooling, urbanization, the population for age, sex, in each province for years of study were used.
Despite the fact that data recordings have been more noticeable in recent years, this process continues to have many problems. In this study, different methods will be used for each of the problems. The failures in the cancer registration system are different, which can be the repeated registration of an individual in different provinces or at different times (diagnosed more than 90% of similarity as a specific individual using text mining method). We also consider the change in the number of provinces and boundaries in Iran (31 provinces divided in 2011 is considered).
- Estimation of the incidence rates and numbers of each cancer at the provincial and national levels from 1990 to 2016
- Detection high risk age and sex groups as well as high risk provinces based on the incidence of all cancers or specific types of cancer.
