Immunocytochemical assays in human endometrial carcinomas: a multiparametric computerized analysis and comparison with nonmalignant changes.
Immunocytochemical assay (ICAs) were performed on frozen sections from human endometrial samples (n = 89) including normal endometrium, decidua, hyperplasia with and without atypia, and carcinomas. Monoclonal antiestrogen receptor (ER), anti-laminin (Lam), anti-type IV collagen (Coll IV), and anti-Ki67 were applied with avidin-biotin-peroxidase complex or peroxidase-antiperoxidase complex. The results of the ICAs were evaluated through a computerized system of image analysis referred to as SAMBA. It was shown that this system provided for an accurate reliable and reproducible analysis of ICAs in tissue sections. It is concluded that this multiparametric and standardized method of analysis of ICAs can further be applied in correlations with clinical and biochemical data.
