Differences of gastric cancers between the greater and the lesser curvature Part I. Macroscopic and microscopic differences of the gastric cancers between those of the greater and of the lesser curvatures

Abstract

Specimens of 47 cases of gastric cancer were investigated. In the types of Borrmann III and IV, diffuse infiltration was always seen to the side of the lesser curvature, while it was never observed in the side of the greater curvature. According to the Imai's C. P. L. classification, much more malignant features were seen in the side of the lesser curvature than in that of the greater. On the other hand, the rate of growth of the stroma, being considered a vital defensive reaction, was higher in the side of the greater curvature
