Association of clinicopathological features and gastric cancer incidence in a single institution

Abstract

BACKGROUND: Stomach cancer is the fifth most common malignancy. In 2012, 952,000 cancers were diagnosed worldwide, which led to 723,000 deaths. Elderly men are the most frequently observed category of gastric cancer patients, mostly affecting the antrum. The objective of this study was to analyze the association of age with sex, tumor sites, types of surgical intervention, and diagnosed anatomical pathologies in cases of gastric cancer. METHODS: This cross-sectional descriptive study analyzed the associations between age, sex, tumor sites, types of surgical intervention, and diagnosed anatomical pathologies among the total gastric cancer incidences during medical treatments from January 2016 to May 2019. The study samples were collected from the total gastric cancer respondents who met the inclusion criteria during medical treatments within the study period. RESULTS: Gastric cancer was most frequently observed among females (56%) and those aged 50-70 years old (47%). Most respondents had advanced stages of gastric cancer at first enrollment at our institution. The most frequently found tumor site was the corpus (43%). The most frequently performed type of surgical intervention was jejunostomy feeding (26%), and the most frequently diagnosed anatomical pathology was adenocarcinoma with poorly differentiation (39%). Overall, age had statistically significant correlations with sex (p < 0.001), tumor sites (p < 0.001), types of surgical intervention (p < 0.001), and diagnosed anatomical pathologies (p < 0.001). CONCLUSION: Gastric cancer was more common in males than females. In the older age group (>50 years old), gastric cancer was more prevalent in women than men, and the gastric tumor tended to be more distal. Non-cardia gastric cancers were more prevalent than cardia gastric cancers.
