Representative images of human papillomavirus (HPV) E6/E7 RNAscope in paraffin-embedded endocervical adenocarcinoma (ECA) samples. A HPV mRNA was detected using RNAscope in ECA (T) and non-tumorous tissues adjacent to ECA (N). Representative images of scores 0 (T0), 1 (T1), 2 (T2), 3 (T3) and 4 (T4) are shown. B The proportion of RNAscope scores in ECA tissues. C Positive rates of HPV by PCR, RNAscope, HPV genotype and p16 IHC. (D) Receiver operating characteristics curve for HPV, detected by PCR, immunohistochemistry, genotyping and RNAscope for HPV-associated vs. non-HPV-associated types
