Background: Cancer registry can be a very important component of health information system in developing countries. Routine collection of data and ongoing monitoring of their quality can have a crucial role in priority setting and evidence-based policy making for controlling cancers and trends follow-up in low and middle-income countries. Evaluation of cancer registered data consists of four important components including: comparability, completeness, validity, and timeliness. Similar frameworks are utilized in different countries all over the world.Methods and Materials: We will use the national annual cancer registry reports in Iran alone or perhaps along with other Iranian published reports about childhood cancer incidence to determine the stability and trend of incidence rates over time and compare above mentioned reports with childhood cancer incidence data reported by other countries through a systematic review as well as in some cases meta-analysis in order to assess data quality. Data will also be collected from other sources such as death certificates to estimate mortality rates and other different methods will also be additionally applied, by use of which death certificates would be utilized to assess the quality of data, too. Conclusion: As the first step for proper measuring incidence rate of all types of cancers all over the country, we will assess and evaluate reported national cancer registry data in Iran in order to estimate the national burden of cancers in 1990-2013.
