The Incidence Rate of Gastrointestinal Tract Cancers in Kerman Province during ۱۹۹۶-۲۰۰۰

Background: Cancer as the second leading cause of death following cardiovascular diseases has always been a threat to human life and due to its peculiar nature and lack of a favorable treatment, it is considered as a research priority in all communities. Understanding the geographical distribution of the incidence of various tumors, constitutes the first step in health and treatment planning. This study was carried out to review the incidence rate of gastrointestinal cancers in Kerman province and estimate disease load in this geographical area. Methods: Through a community-based registration system, all the documents related to cancer diagnosis in Kerman province from ۱۹۹۶ to ۲۰۰۰ were investigated. Results: Among ۵۸۶۷ registered cases of cancer with an average age of ۵۱.۵±۲۰.۶ years, men composed ۵۵.۵% and women ۴۴.۵% of the cases and ۱۳۰۳ ones (۲۲.۲%) had gastrointestinal tract cancers among them gastric tumors (۳۹%) had the highest incidence rate. Following gastric tumors, tumors of colon (۲۹.۴%), esophagus (۱۲.۵%), liver (۵.۸۳%) gallbladder (۵.۳%), and pancreas (۲.۸۴%) acquired the next ranks in regard to the incidence rate. The incidence pattern of aforementioned cancers in men showed the same pattern as the general population, but in women, colon tumors with the incidence rate of ۳۵% have the highest incidence rate while tumors of the stomach (۲۹.۷۱%), esophagus (۱۰.۱۵%), gallbladder (۹.۸%), liver (۵.۲۶%) and pancreas (۴.۳۲%) were the next. Conclusion: Although, various GI malignancies have a lower incidence rate in Kerman province compared with other countries, the fact that these malignancies account for ۲۲.۴% of all malignancies, greatly enhances the need for serious planning for prevention, early diagnosis and correction of improper dietary habbits in this province. Moreover development of a versatile cancer registration system to evaluate the domestic comparisons seems essential.
