| Abstract |
Forty-seven surgically resected small cell lung carcinomas (SCLC) were immunohistochemically studied by using antibodies to various neuroendocrine and epithelial markers. SCLC was shown to be subdivided into two categories, with and without the immunoreactive neuroendocrine markers aromatic L-amino acid decarboxylase, gastrin-releasing peptide, serotonin, chromogranin A and neurofilament protein. Neuron-specific enolase (NSE) and creatine kinase BB isoenzyme (CK-BB), which are also considered to be neuroendocrine markers, had a tendency to be widely distributed in the SCLC with a neuroendocrine marker, but the immunoreactivity for both NSE and CK-BB varied in the SCLC without neuroendocrine markers. Therefore they were not included in the classification. Epithelial markers keratin, involucrin and epithelial membrane antigen were frequently observed in the SCLC with neuroendocrine markers, but less so in the SCLC without neuroendocrine markers. The data are discussed briefly in relation to "classic and variant" forms of SCLC in vitro and to a recently proposed histological classification of SCLC.
