Cytological Classification for the Diagnosis of Lung Cancer

Abstract

An effort was made to outline and to standardize the cytological diagnosis of the lung cancer.
Grouping, shape, staining of the cells, nucleus and nucleoles were examined. The ratio of nucleus to cytoplasm was also compared on a large group (over 1, 000 cases) of proven lung cancer.
The characteristics of each cell type;squamous cell carcinoma, adenocarcinoma, large cell anaplastic carcinoma and small cell anaplastic carcinoma, were illustrated, and the summary of these were shown on the table and the microphotography.
