Two pathologists independently scored the expression levels of ERα, PR(A+B), and PRB in the stroma and epithelium of normal, cervical intraepithelial neoplasia grade 2 and 3 (CIN2/3), carcinoma in situ (CIS), and invasive cervical carcinoma (ICC) specimens. The gene discussed is RB1; the disease is cervical intraepithelial neoplasia.
