Peroxidase-antiperoxidase staining for estrogen and progesterone in scirrhous type of gastric cancer: possible existence of the estrogen receptor.
Tissue specimens from patients with the scirrhous type of gastric carcinoma were stained using the peroxidase-antiperoxidase (PAP) method. Nine out of thirty-seven specimens (24 per cent) showed positive estrogen staining, and here tissues from male or older patients were usually stained. Cumulative survival rate in patients whose tissue showed a positive estrogen staining was higher than that in case of a negative estrogen staining. Four out of thirty-one specimens (13 per cent) stained positively for progesterone, all four patients being male. These results suggest that estrogen and progesterone may relate to the growth of the scirrhous type of gastric cancer.
