The mean (+/- SD) ages were 63.25+/-12.79 and 59.45+/-13.39 yr for men and women, respectively . Gastric cancer was the most common GI tract cancer with an annual ASR of 21.3 per 10(5) for males and 8.2 for females . The annual ASRs for esophagus and colorectal cancers were 9.4 and 6 in males and 7.1 and 9.2 in females. Gastric cancer was significantly more common among men although women were more likely to develop cancer in younger age. Some 14% of our subjects with colorectal cancer were under the age of 40. This first report from East Azarbaijan, suggests a need for further evaluations to map out the risk factors and interventions.
