Popis: Endocervical adenocarcinomas (ECA) and endometrial adenocarcinomas (EMA) are uterine malignancies that have differing biological behavior. The choice of appropriate therapeutic plan depends indeed on the tumor’s site of origin. In this study, we not only compare the individual expression status of five immunomarkers (ER, PR, Vim, CEA, and p16INK4a), but also evaluate whether p16INK4a adds value to the ER/PR/Vim/CEA panel characteristics in distinguishing between primary ECA and EMA. A tissue microarray (TMA) was constructed using paraffin-embedded, formalin-fixed tissues from 35 hysterectomy specimens, including 14 ECA and 21 EMA. TMA sections were immunostained with five anti-bodies, by avidin–biotin complex (ABC) method for antigen visualization. The staining intensity and area extent of the immunohistochemical (IHC) reactions were appraised by using the semi-quantitative scoring system. The four respective markers (ER, PR, Vim, CEA) and their combined panel expressions showed significant (p
