a study on the immunohistochemical expression of napsin a tf 1 and p40 in lung carcinoma based on the recent who classification

Abstract

To analyze the expression of the immunohistochemical newlinemarkers NAPSIN A, TTF 1 and P40 in lung carcinomas and based newlineon their expression, subtype these Non -Small Cell Lung Cancers newline(NSCLC) into adenocarcinomas and squamous cell carcinomas as newlineper the recent WHO Classification. newlineOBJECTIVES newline To study the demographic features of NSCLC. newline To study the histological features of NSCLC especially newlineadenocarcinoma and squamous cell carcinoma. newline To compare tumor subtypes with demographic findings. newline To assess the expression of NAPSIN A, TTF 1 and P40 in newlinelung carcinomas diagnosed histopathologically as newlineadenocarcinoma, squamous cell carcinoma and non -small newlinecell lung carcinomas newline
