Anatomicopathological Distribution of Gastric Cancer over Ten Years

Gastric cancer is the fourth most common cancer and the second cause of cancer-related death worldwide. Various types of gastric cancer are common in different areas in Iran. In this study, we aimed to evaluate 10 years of endoscopic and histopathological data of patients diagnosed with gastric cancer in Babol, Iran.

This descriptive cross-sectional study included all patients with recorded data who were referred to the endoscopic unit with gastric cancer during 2006-2016. Data included demographic characteristics (age, sex, body mass index [BMI], smoking, opium addiction), endoscopic characteristics (site of involvement in different gastric areas), and histopathological types (adenocarcinoma, lymphoma, gastrointestinal stromal tumor (GIST)), which were extracted from the endoscopy unit database and were analyzed using SPSS software.

435 cases of gastric cancer were studied. The mean age was 66.75 ± 14.03 years, with a minimum and maximum age of 21 and 94 years, respectively. The data demonstrated that men were affected 2.3 times more than women (69.2% were men and 30.8% were women). 420 out of 435 patients were diagnosed with adenocarcinoma. Also, 46 cases (or 10.9%) were signet ring adenocarcinoma, and 374 cases (89.1%) were non-signet ring adenocarcinoma. Eight cases were lymphoma, and seven cases were GIST. In addition, 112 patients (25.8%) had proximal, and 323 patients (74.2%) had distal involvements, mostly involving the antrum (36.8%). Regarding the effects of cigarette smoking and opium addiction, 124 patients diagnosed with gastric cancer were investigated. 13 patients (10.4%) had a history of smoking. Also, five patients (4%) had a history of opium addiction. Three patients (2.2%) had a history of both.

In our study, non-cardiac intestinal type adenocarcinoma was more prevalent than cardiac type
