EPIDEMIOLOGY AND HISTOPATHOLOGY OF GASTRIC CANCER IN URMIA

Gastric cancer is one of the common gastrointestinal cancers with global
incidence and one of the most common cancers in the northwestern of Iran. This study aimed to
determine the prevalence of gastric tumors and their anatomical location using the pathologic
specimens of patients have been conducted in Urmia.
Materials & Methods: The study population comprised all samples sent to Pathology Laboratory
of Imam Khomeini Hospital, Urmia; in a 5- years period during 2002-2007 were studied, and
their documents are available. Information extracted included: age, sex, smoking habit, type of
