A 70-Year-Old Man with a Rare Type of Gastric Cancer

Abstract

According to the estimate of GLOBOCAN, more than 800,000 deaths are attributed to gastric cancer and more than 1,100,000 new cases of gastric cancer were detected worldwide in 2020. About 75% of all deaths and new cases are reported in Asia. The two principal subtypes of gastric adenocarcinoma, including intestinal type and diffuse type, have been elaborately explained. Intestinal type adenocarcinoma is stratified into three subgroups: papillary, tubular, and mucinous. Diffuse-type adenocarcinoma comprises signet-ring cell carcinoma and other poorly cohesive carcinomas. A small part of gastric cancers is classified as indeterminate type.
