Abstract

Cancer is the most common cause of death in developing and developed countries, accounting for nearly 13% of world death. In Iran, gastrointestinal cancers are common. Therefore, this study was conducted to evaluate the gastrointestinal tract tumors in Urmia Imam Khomeini hospital. Material & Methods: In this cross-sectional study, pathology reports of 741 patients with gastrointestinal tumor were evaluated. Results: Of 741 reported tumor, 705 cases (95.14%) were malignant, 36 cases (4.85%) were benign. 61.8% of patients with malignant tumors were men and 38.1% were women. The mean age of patients with malignant tumors was 60.2±13.35 and the mean age of patients with benign tumors was 47.7±10.49. The most abundant malignant tumor was adenocarcinoma with 481 cases (68.22%) followed by squamous cell carcinoma with 137 cases (19.43%) and the most frequent benign tumor was lipoma(52.7% of cases). The malignant tumors were observed mostly in the ages of 71 or higher (232 cases (32.9%)). In the evaluation of anatomical location of the malignant tumors, in esophagus, the precise location was not reported in most cases (63.7%). In the stomach, the cardia with 29.27%, in the small intestine, the duodenum with 66.6%, and in the colorectal region, the rectum with 41.9% were the most involved locations. Conclusion: The results of our study indicated that the most abundant malignant tumor of the gastrointestinal tract was adenocarcinoma and the most abundant benign tumor was lipoma. Malignant tumors were observed mostly in men while benign tumors were mostly observed in women. The high frequency of malignant tumors in the ages of 71 and higher indicates the importance of early-onset screening for the prevention of malignant tumors in older ages.
