  • Title: A comparative cytopathologic study of noninvasive and invasive squamous cell carcinoma of the lung.
    Author: Erozan YS, Pressman NJ, Donovan PA, Gupta PK, Frost JK.
    Journal: Anal Quant Cytol; 1979; 1(1):50-6. PubMed ID: 546279.
    Abstract:
    Atypical cells and tissue fragments from the sputum of patients with early and advanced stages of squamous cell carcinoma of the bronchus are objectively characterized and quantitatively compared in this paper. Four classes of single-cell features of cytoplasm, nucleus, nucleolus and nuclear-cytoplasmic ratio are analyzed as a function of cell size and tumor development stage. Distinct differences in the cellular patterns are observed which may enhance cytologic discrimination between noninvasive and invasive stages of squamous cell carcinoma of the bronchus. Initial results justify the application of more sensitive measurement techniques (i.e., automated cytology) to an enlarged data base.
