We analyzed high-risk HPV infection by HPV-RNA in situ hybridization and EGFR gene copy number gain (CNG) by chromogenic in situ hybridization and by determining the protein expressions of p16, Rb, and EGFR by immunohistochemistry in 101 SNSCC cases.
Molecular tests (in situ hybridization and polymerase chain reaction) showed no evidence of human papillomavirus infection and p16 staining was negative.
We aimed to assess utility of such histological features and p16 as surrogate markers of HPV infection in a retrospective cohort of 33 cases of severe epithelial dysplasia, with matched clinicopathological data and histological features.

Adjunctive immunohistochemistry tests for human papillomavirus (HPV) infection include p16 and Ki67 as well as the more recently discovered biomarkers importin-β, exportin-5, Mcl1, and PDL1.
The present study was designed to investigate the association between a change in vaginal local immunity and human papilloma virus (HPV) infection outcome in patients with cervical lesions, through the study of the expression of vaginal local immune factors, interleukin (IL)-2, IL-10, secretory immunoglobulin A (sIgA) and IgG, in patients with different grades of cervical lesions and different degrees of cervical lesions caused by HPV infection prior to and following treatment.
HPV does not play an etiologic role in inverted papilloma or oncocytic papilloma of the sinonasal region. p16 immunostaining should not be used as a surrogate marker to evaluate the HPV infection status in these lesions.
Tumor sections from established tumors were stained for p16 (surrogate for human papillomavirus (HPV) infection), stromal (Masson's trichrome) and vascular (CD31) markers.
Histological examination, presence of HPV infection and OncoScan analysis of DNA extracted from two well-defined areas with different p16 expression profiles were performed.
Since E6 and E7 viral protein interaction with cell proteins pRb and p53 is mandatory for cell transformation, HPV RNA CISH is functionally relevant and acutely reflects active oncogenic HPV infection.
The aim of this study was to identify the association between human papilloma virus (HPV) infection and ocular surface squamous neoplasia (OSSN) using p16 immunohistochemistry (IHC) and deoxyribonucleic acid (DNA) chip test.Thirty-eight patients who underwent surgical excision of OSSN were retrospectively studied using tissue samples.
Tumor sections from established tumors were stained for p16 (surrogate for human papillomavirus (HPV) infection), stromal (Masson's trichrome) and vascular (CD31) markers.
The prevalence of HPV16 in Chinese OSCC patients was low. p16 overexpression decoupled from HPV infection was not a prognostic marker for OSCC patients except for patients with the buccal mucosa cancer.
