 We analyzed the pathological features of gastrointestinal cancer in the elderly. Esophageal carcinoma in the elderly did not have special clinicopathological features compared with the non-elderly. In gastric cancer in the elderly, it tends to occur in the lower-third of the stomach. These cancers are often elevated types macroscopically. The majority of early cancers are differentiated type. Many multiple cancers were observed. In colorectal cancer, with age, right colon cancers increase with age, and rectal cancers decrease. In gastric and colorectal cancer, the histological group with similar clinicopathological and molecular pathological characteristics, such as solid-type poorly differentiated gastric adenocarcinoma, medullary type poorly differentiated colorectal adenocarcinoma, and mucinous colorectal carcinoma are presented. Most of them show microsatellite instability. We need to understand the characteristics of these elderly gastrointestinal cancers and to provide cancer care tailored to the characteristics.
