    Abstract:
    Monoclonal antibody based immunohistochemistry is a very powerful tool for the establishment of a pathological diagnosis of lung cancer. Applying a panel of intermediate filament antisera and an antibody recognizing neuroendocrine differentiation we have tested about 240 human lung tumors and 15 human lung tumor cell lines. Our results can be summarized as follows: a differential diagnosis between neuroendocrine and non-neuroendocrine lung tumors can be obtained by the application of the monoclonal antibody MOC-1 directed against neuroendocrine antigens. Immunohistochemistry can lead to a better recognition of lung tumor heterogeneity within the established histologies. Examples of this phenomenon are: the presence of neuroendocrine and/or neural components within non-neuroendocrine tumors. The presence of squamous cell or adenocarcinomatous differentiation in non-SCLC can be detected by chain specific anti-cytokeratin antibodies. The degree of differentiation towards the variant type within SCLC can be detected by the monoclonal antibody directed against neurofilaments. lung cancer cell lines can serve as an in vitro model for immunohistochemical studies on different lung cancer subtypes.
