Abstract

Clinicopathological studies were carried out on 225 cases of the gastric cancer by dividing them into two groups, i.e., those of over 65 years old (A group) and of less than 65 years old (B group), and results were as follows: 1) Abdominal pain was most frequently found as an initial symptom in both groups followed by asymptom. Therefore, regardless of showing symptoms, UGI series should be performed. 2) Of operated cases of early gastric cancer, type IIcs were most frequently seen in both groups and more than half cases in group A were type IIc. 3) Of operated cases of advanced cancer, localized type and infiltrative type were frequently seen in group A and group B, respectively. 4) As to histological types, differentiated carcinoma and undifferentiated carcinoma were frequently seen in group A and in group B, respectively. Incidence of signet ring cell carcinoma in group B was signifficantly higher than that in group A.
