Jan 25, 2024 · A. p16 immunohistochemistry is not recommended as a routine adjunct assessment when the biopsy interpretation is negative, CIN I or CIN III. Strong and diffuse block staining for p16 supports a categorization of precancerous disease. Any identified p16 positive area must meet H&E morphologic criteria for a high grade lesion to reinterpreted as ...

Expression of p16 above 67% of the epithelium is associated with negative E4, while expression of p16 up to 67% of the epithelium is associated with positive E4 (p < 0.001) (Cancer Med 2020;9:2454) Dual marker approach with p16 / E4 may help grade cervical intraepithelial neoplasia (CIN) lesions and improve disease stratification ( Mod Pathol ...
