Evaluation of Napsin A, Cytokeratin 5/6, p63, and Thyroid Transcription Factor 1 in Adenocarcinoma Versus Squamous Cell Carcinoma of the Lung

Abstract

The source of the antibody is important in avoiding false-negative results. The most cost-effective tissue-preserving panel for small biopsy specimens in the differential diagnosis of lung adenocarcinoma versus squamous cell carcinoma is a combination of p63 and napsin A.
