Introduction Head and neck squamous cell carcinoma HNSCC is the sixth most common cancer paraziti zivotinja, with an estimated annual burden ofdeaths andincident cases [ 1 ].
HNSCCs are etiologically heterogeneous, being caused by tobacco use, alcohol consumption, poor oral hygiene, exposure to certain chemicals, and genetic features [ 2 — 4 ], as well as viral infections [ 56 ]. Chaturvedi et al.

The proportion of HPV-positive oropharyngeal cancers among HNSCCs has been increasing over the past decades in many parts of the world, whereas the overall incidence of HNSCC is decreasing, consistent with declines in tobacco use [ 12 ]. Several studies reported a steady increase in the proportion of HPV-driven oropharyngeal cancer cases in the United States [ 13 ], in Sweden [ 1415 ], in Australia [ 16 ], and in New Zealand [ cervical human papillomavirus disease ].
HPV has also been associated, to a much lesser extent, with non-oropharyngeal cancers such as oral or laryngeal cancer.
Similar rates have been obtained in Kazakhstan, where South America had the highest HPV-attributable fraction All patients were diagnosed with keratinizing or non-keratinizing squamous cell carcinomas. The study implied the use of archival material only, and it did not envisage any contact with the patients. No informed consent was available, due to the retrospective design of the study and the large proportion of deceased and untraceable patients.
All data were fully anonymized before access. In addition, to monitor possible cross-contamination during the sectioning, empty paraffin blocks were processed every 10th cancer specimen.
Biotinylated amplification products are hybridized to ubC and HPV type-specific probes representing splice junction sequences on Luminex beads, followed by staining with streptavidin-phycoerythrin, and quantified in a Luminex analyzer.
The analytical sensitivity of the respective assays per reaction is 10, copies for HPV70, 1, copies for HPV67, and 10— copies for the remaining 19 HPV types and for ubC [ 39 ].
The HPV RNA assay has been widely applied and validated as a marker for HPV transformation in carcinoma of the anogenital region, such as the cervix [ 3940 ], vulva [ 41 ], penis [ 42 ], lung [ 43 ], and scrotum [ 44 ], as well as carcinoma of the head and neck [ 3033 ], and specifically oropharynx [ 4546 ], unknown primary of the neck [ 4748 ], larynx [ 27 ], and esophagus [ 49 ]. Briefly, slides were de-paraffinized in xylene and rehydrated in graded alcohol.
The antigens were retrieved for 10 minutes using a pH 9. Different from the instructions of the manufacturer, specimens were then microwaved in preheated Vector H unmasking solution Vector Laboratories, Burlingame, CA for 15 minutes. This step was followed by incubation of the p16 primary mouse anti-human antibody clone E6H4 for 60 minutes.
Finally, slides were counterstained with hematoxylin, dehydrated, mounted with permanent mounting medium, and cover-slipped. Immunoreactivity was visualized by light microscopy. A continuous, diffuse staining for p16 within the cancer area of the tissue sections was considered as positive, and a focal staining or no staining was considered negative.
The validity of the p16 IHC staining result was assessed by evaluating the presence of p16 internal control staining. Discrepant cases were re-checked by a pathologist, and the cervical human papillomavirus disease classification of the staining was based on the majority consensus of the working group.
