[Immuno-cytochemical and -histochemical localization of human keratin proteins in various kinds of cancerous lesion].
Immunoperoxidase staining for human keratin proteins (hKP) was performed cytochemically in samples from 79 cancer patients, and histochemically in samples from 134 cancer patients. Immunohistochemically, hKP was present in almost all patients with squamous cell carcinoma (lung), transitional cell carcinoma (urinary bladder), adenocarcinoma (lung, stomach, breast, ovary), bronchiole-alveolar carcinoma (lung), and large cell carcinoma (lung). It was detected in 40% of the patients with small cell carcinoma (lung). Histochemically, hKP was present in patients with squamous cell carcinoma (lung, uterine body), adenocarcinoma (lung, stomach, colon, gall bladder, thyroid, uterine body), adenosquamous cell carcinoma (gall bladder, uterine body), Signet-ring cell carcinoma (stomach), clear cell carcinoma (uterine body) and undifferentiated carcinoma (uterine body). However, it was not detected in patients with brochiole ++-alveola ++ carcinoma (lung) and mucinous carcinoma (gall bladder).
