[Immunocytohistochemical studies of AFP producing gastric cancer--cytomorphology and characteristics of AFP positive cells].

In 24 cases (5.5%) out of 438 cases of gastric cancer showing serum AFP over 20 ng/ml, 14 cases (3.2%) showed AFP positive reaction in cancer cells by immunostaining.

[Diagnosis of precancerous lesions of the endometrium].
