Histological classification of gastric cancers

ABSTRACT

A histological study on gastric cancers was carried out on 452 gastric cancers diagnosed at K hospital. The results: (1) Gastric cancers are commonest at the age 61-70, the male/female rate is 1.38. (2) The great majority of gastric cancers are gastric carcinomas (96.68%) with the highest rate of tubular adenocarcinoma (56.16%) and most of these cases are highly differentiated (40.24%); stromal tumors and malignant lymphomas are very rare tumors (1.55% for each type); Non mucinous carcinoma rate is higher than that of mucinous carcinoma rate is higher than that of mucinous carcinomas (94.47% vs. 5.53%). (3) Immunohistochemical is very useful in the diagnosis of small cell carcinomas, one neuroendocrine tumor, one c-kit mutation gastrointestinal stromal tumor (Cajal cell tumor) and three gastric T cell lymphomas. The significance of the data was discussed.
