Histopathological diagnosis included 30 LSIL, 33 HSIL, 29 HPV-related SCC, 8 HPV-related adenocarcinoma and 15 negative for cervical intraepithelial lesions cases. RNAscope technology, originally applied to paraffin samples, was adapted for LBC by modifying slide type selection, extending target retrieval, and enhancing permeabilization.
