Research in Relation to the Prognosis after Resection of Gastric Cancer Part II

Abstract

In Part I, various factors affecting the prognosis after resection of gastric cancer were reviewed from different viewpoints in relation to clinical and pathohistological indices.
In Part II, clinical and pathohistological investgations were done on the mode of vascular invasion after resection of gastric cancer, and the same time, an examination was made on the relationship between these and the survival rates at given number of years.
It has been established that male patients showed higher lymphatic vascular invasion, and it stendency increase with age. Even though the the tumors were small, vascular invasion could occur, and in such case, the prognosis was very poor.
Moreover, the higher the degree of infiltrative growth and the deeper the extention, the result was a more severe invasion, and especially, the importance of sm (Tela submucosa), as the site of metastasis and infiltration, was confirmed.
