Cervical histopathology variability among laboratories: a population-based statewide investigation. Given the intrinsic subjectivity of the morphologic assessment of cervical biopsies, the variability between different pathologists in the frequency at which they request p16 IHC is not surprising. The lower anogenital squamous terminology standardization project for HPV-associated lesions: background and consensus recommendations from the College of American Pathologists and the American Society for Colposcopy and Cervical Pathology. We would also like to point out that the LAST criteria recommend p16 IHC for all cervical biopsies LSIL, irrespective of their histologic appearance from women with high-risk colposcopic referrals.12 If pathologists decide to stain all cervical biopsies with p16 they should keep in mind many of the other LAST recommendations.12 They should remember that diffuse/block-like p16 positivity is not an independent indicator of HSIL and be careful to not upgrade p16-positive CIN1 lesions to CIN2 or to downgrade histologic CIN3 lesions that are p16 negative. Vaccination programs may provide prevention from HPV infection in high-risk population. Terrell JR, Rybak I, Lyu Y, Konia T, Fung MA, Qi L, Kiuru M. J Cutan Pathol. In addition, we aimed to see if any of these markers can differentiate endometrial from endocervical adenocarcinomas. In summary, these findings have important implications for deciding when to utilize p16 IHC for cervical biopsies. PMC As part of this project, a working group was tasked with developing recommendations for determining which, if any, biomarkers were useful in diagnosing HPV-associated lesions and in reducing diagnostic interobserver variability. Horn LC, Reichert A, Oster A, et al. modify the keyword list to augment your search. Human papillomavirus (HPV) type 16 has also been suggested to play a role in the etiology of head-and-neck squamous cell carcinoma (HNSCC). [1] In India, it ranks among the top three types of cancer. p16 expression indicates HPV-associated oropharyngeal squamous cell carcinoma (OPSCC), but not non-OPSCC. The p16 (CDKN2a/INK4a) tumor-suppressor gene in head and neck squamous cell carcinoma: A promoter methylation and protein expression study in 100 cases. p16 Immunohistochemistry Interpretation by Nonpathologists as an Am J Surg Pathol. The IHC expression of p16 was classified according to nuclear and cytoplasmic positivity. According to Ralli et al., HNSCC was associated more with paan chewing and was more in nonalcoholics. In this cross-sectional observational study, a total of 100 cases of HNSCC were taken. Peltonen JK, Helppi HM, Pkk P, Turpeenniemi-Hujanen T, Vhkangas KH. The tertiles can be thought of as corresponding to pathologists who: (1) favor sensitivity over specificity when interpreting cervical biopsies, (2) balance sensitivity with specificity, and (3) favor specificity over sensitivity (Fig. 2021 Oct 5;14:1419-1425. doi: 10.2147/CCID.S333376.

A significant association was seen between p16 expression and history of abnormal sexual habits (P = 0.02) in our study. 2010;34:10771087. In CERTAIN there was a wide variation in the frequency with which p16 IHC was requested by the individual ISPs, even after undergoing specific training on the LAST criteria before beginning their initial H&E reads. J Cutan Pathol. found no statistically significant association between p16 expression and tobacco use. According to a study by Ralli et al., a significant association was seen between p16 expression and history of multiple sexual partners (P = 0.003). Evaluation of controls, interpretation and reporting of results, and experience of the pathologist are factors accounting for postanalytical variables [44].Because of interobserver variability in reporting p16 IHC, investigators are looking to pursue methods for automated analysis [48].For such an application, the antibody must be easy to use and reproducible with protocols that are .

Cytological interpretation of p16 immunohistochemistry in head and neck 4. 4). The new guidelines proposed by the College of American Pathologists (CAP), for HPV testing in head and neck carcinomas in routine clinical practice proposed the interpretation of p16 IHC as follows: tumors with lack of staining or < 70% of nuclear and cytoplasmic staining are classified as HPV negative, while tumors with 70% of nuclear and . A descriptive study was carried out for all the variables included in the study. [12,17] They hypothesized that tumors exhibiting p16 expression effect cell differentiation. p16 expression was determined by immunohistochemical (IHC) staining and correlated with clinicopathological parameters. Lymph node involvement was present in 26 (26%) cases which was in concordance with various studies in literature,[3,9,16] while higher involvement was reported by Wilson et al.

[25] Grade III tumors were less frequently observed in our study when compared to study by Solomon et al. If so, the case was designated a LAST case for this ISP; otherwise, the respective case was designated non-LAST for that reader. Agreement rates of ISPs diagnoses on H&E versus on H&E+p16/LAST with both CPR reference diagnoses dichotomized at the CIN2+ threshold are shown in Table 3. The Lower Anogenital Squamous Terminology (LAST) Project recommends the use of p16 immunohistochemistry as an adjunct to morphologic assessment of cervical biopsies according to a specific set of criteria. To evaluate the effect of the current clinical recommendations calling for the use of adjunctive p16 IHC staining, the 70 ISP readers were requested to specify for each case during the initial interpretation of the H&E-stained slides in round 1 whether they would order adjunctive p16 IHC, based on the available set of LAST criteria. Bookshelf Similarly, there were fewer ISP CIN1 diagnoses when p16 IHC was utilized compared with H&E alone, 8091 versus 8152, respectively (Table 2).
