ABSTRACT
BACKGROUND: High-risk human papillomavirus (hrHPV) testing has become integral in the screening and treatment protocols for cervical neoplasia. Stand-alone HPV testing is advocated as a screening tool for cervical neoplasia. However, negative hrHPV tests with diagnosis of high-grade squamous intraepithelial lesion or worse (≥HSIL) have been reported. We report our experience with paps diagnosed as HSIL, negative hrHPV testing, and subsequent follow-up. METHODS: Of 303 women with HSIL diagnosed on ThinPrep pap between 2019 and 2023, 84 (28%) were tested for hrHPV by Roche Cobas. Repeat testing was performed at a referral center. Immunohistochemistry (IHC) for p16 was performed on follow-up biopsies and hrHPV in-situ hybridization. RESULTS: Of 84 HSIL cases, 8 were hrHPV negative. Follow-up biopsies available in 7 cases were ≥HSIL (1 with invasive squamous cell carcinoma, 1 endocervical adenocarcinoma in situ). Follow-up HSIL was found on additional cases of HPV negative atypical glandular cells favor neoplastic and atypical squamous cells favor HSIL. IHC for p16 was positive on all biopsies. hrHPV FISH was negative. CONCLUSIONS: Our experience with hrHPV testing by Roche Cobas demonstrates that some morphologically diagnostic HSIL paps are hrHPV negative: 8.3% of HSIL paps with subsequent histological HSIL were HPV negative. The index case caused concern among our clinical colleagues. Positive staining for p16 is highly suggestive of HPV induced disease. Possible reasons for negative hrHPV testing could include non-hrHPV types, low HPV DNA levels, or HPV types not included in the Cobas testing panel.

OBJECTIVE: Our objective was to determine whether demographic, colposcopic, and pathologic variables are predictive of recurrent cervical dysplasia. STUDY DESIGN: A retrospective review of patients who underwent loop electrosurgical excision procedure (LEEP) was performed. The medical records of the subjects were reviewed to identify demographic, pathologic, and procedural characteristics that predict recurrent dysplasia. RESULTS: A total of 514 subjects were identified who underwent LEEP between 1996 and 2003. Multivariate analysis revealed that advanced age, immunosuppression, and a positive endocervical margin were associated with recurrent dysplasia. CONCLUSION: Demographic and pathologic data can be used to predict the risk of recurrence of cervical dysplasia after LEEP.
