RESUMEN
Introduction and Aims: gastrointestinal cancers [GI] are considered as the most common cancer among men and are the second in women. The aim of this study was to evaluate the changes in crude and age specific incidence rates of gastrointestinal cancers in Neyshabur during 2006-2012
Materials and Methods: in this study the recorded data of Neyshabur's patients with cancer in the hospitals of Mashhad and Neyshabur were analyzed using Excel and SPSS v.16. Crude and age specific incidence rates were also estimated
Results: three hundred and thirty-five [42.8%] out of all 783 patients with cancer, were GI cancers. Gastric cancer showed the highest prevalence [41.8%] with the rate of 63.3 and 36.7 percent in men and women respectively. The results indicated the incidence of gastric cancer had a falling tendency
Conclusion: about half of all the cancers in Neyshabur are of the GI type and their incidence rate up to 2012 showed a decreasing trend so that, this rate is higher in men and older age groups. This decline may be due to numerous reasons such as control of risk factors, failure to identify eligible patients, referring to medical centers outside the province, or an increase in mortality and etc. that needs further investigation
