A method for double-labeling sputum cells for p53 and cytokeratin
- and others
Molecular and immunological techniques may enhance the usefulness of sputum cytology as a screening tool for lung cancer. These techniques may also be useful in detecting and following the early progression of disease from metaplasia to dysplasia, carcinoma in situ, and finally to invasive carcinoma. Longitudinal information on the evolution of these malignant changes in the respiratory epithelium can be gained by prospective study of populations at high risk for lung cancer. This work is significant because double-labeling of cells in sputum with p53 and cytokeratin antibodies facilitates rapid screening of p53 positive neoplastic and preneoplastic lung cells by brightfield and fluorescence microscopy.
