Utility of gene methylation analysis, cytological examination, and HPV-16/18 genotyping in triage of high-risk human papilloma virus-positive women.

Utility of gene methylation analysis, cytological examination, and HPV-16/18 genotyping in triage of high-risk human papilloma virus-positive women. Oncotarget. 2017 Jul 22;: Authors: Tian Y, Wu NY, Liou YL, Yeh CT, Cao L, Kang YN, Wang HJ, Li Y, Chu TY, Li W, Liu X, Zhang Y, Zhou H, Zhang Y Abstract In 2015, the American Society for Colposcopy and Cervical Pathology and the Society of Gynecologic Oncology issued interim guidance for the use of a human papillomavirus (HPV) test for primary screening, suggesting triage of women positive for high-risk human papillomavirus (hrHPV) by HPV-16/18 genotyping and cytology for women positive for non-16/18 hrHPV. The design of the present study was based on this interim guidance and analysis of the methylation status of specific candidate genes, which has been proposed as a tool to reduce unnecessary referral following primary HPV screening for cervical cancer. We performed a hospital-based case-control study including 312 hrHPV-positive women. hrHPV genotyping was performed by nested multiplex PCR assay with type-specific primers.Residual cervical cells from liquid-based cytology were used for extraction of genomic DNA for assessment of the methylation status of PAX1, ZNF582, SOX1, and NKX6-1 and HPV genotyping. Combined with HPV-16/18 genotyping, both a dual methylation test for PAX1/ZNF582 and testing for ZNF582 methylation demonstrated 100% association of methylation with pathology results...
