Abstract
Background: this study aimed to examine the completeness of the sources of gastric cancer registration and estimate the incidence of gastric cancer using population-based cancer registry data in Ardabil province.
Methods: All diagnosed cases of gastric cancer from the years 2014-2016, recorded in three sources-pathology reports, death certificates, and hospital records-were included in the study. To eliminate duplicate cases, variables such as first name, last name, national ID number, age, gender, date of birth, father's name, and city of residence were used. For estimating the incidence rate, the three-source capture-recapture method and log-linear models were applied.
Results: The incidence based on reported cases by three sources in the years 2014, 2015, and 2016 was 36, 35, and 43 respectively, totaling 99 per 100,000 people (33% women and 66% men). Based on estimated cases, the incidence per year was 85, 63, and 92 cases, totaling 141 per 100,000 people (in men and women, 179 and 100 per 100,000, respectively). The highest sensitivity was related to the pathology source (observed 69.1%, estimated 48.5%), and the lowest was related to the hospital source (observed 18.2%, estimated 12.8%).
Conclusion: The incidence of gastric cancer in Ardabil province was 99 per 100,000 people based on reported cases and 141 per 100,000 people based on estimated cases. The pathology source had the highest sensitivity, while the hospital source had the lowest sensitivity.

Abstract
Background & objectives: Cancer is a major public health problem in many countries of the world. At the present time, cancer is the third leading cause of death in developing countries. The aim of this study was to determine of epidemiologic status and incidence rates of cancers in the patients above 15 years old in East Azerbaijan province , Iran.
Methods: This cross-sectional study was performed on 3832 new cancer cases were obtained from cancer registries in East Azerbaijan province in 2012. Characteristics of all registered cancers (including age, sex, and etc) were collected in a special form. Then the data were summarized and coded using the International Classification of Disease (ICD). Frequency, mean, standard deviation and 95% confidence interval of the study variables were calculated. Age standardized incidence rate was performed by direct method using the world standard population. The data was analyzed by SPSS 16 software.
Results: Among 3832 cases, 2047(53.5%) were males and 1782 (46.5%) were females. The mean age and standard deviation of cancer incidence were 58.1 and 15.8 years, respectively. The overall incidence rate of all types of cancer in population was 132.5 in 100000 people per year. Among men, the highest frequency (263) of all cancers occurred in the 65-69 age group but in women the highest (220) of them occurred in the 50-54 age group. The highest incidence rate (813.3 per 100000) of cancers had occurred in men who were older than 85 years. While the highest (406.3 per 100000) of them in women had occurred in 70-74 years. The most common cancers among males and females were stomach (11.4%) and breast (30%), respectively. Histopathologically the most common cancers of stomach, breast and skin were adenocarcinoma, infiltrating duct carcinoma and basal cell carcinoma, respectively.
Conclusion: According to the results, the most common cancers in East Azerbaijan province were breast and stomach, respectively. Therefore, comprehensive and complementary studies for recognizing relevant factors seem to be essential.
