Expression of estrogen and progesterone receptors in non-small-cell lung cancer: immunohistochemical study.


Estrogen receptor (ER) and progesterone receptor (PgR) have been recognized as being involved in the tumourigenesis of non-small-cell lung cancer (NSCLC). Forty-nine resected NSCLC (39 males and 10 females) were studied immunohistochemically in formalin-fixed, paraffin-embedded sections for ER and PgR. There were 26 squamous cell carcinomas, 22… (More)
