Immunohistochemistry (IHC) · Urology
This test uses a combination of several antibodies (applied to a single slide) that differentially stain for basal cells and neoplastic cells in the prostate: P504S stains prostate adenocarcinoma, whereas p63 and the high molecular weight cytokeratins stain benign prostate basal epithelial tissue. This combination may help differentiate prostate cancer from precancerous lesions such as prostatic intraepithelial neoplasia (PIN), especially when tissue is limited.
