Evaluation of Host Gene Methylation as a Triage Test for HPV-Positive Women-A Cohort Study.

Objectives: This study was designed to evaluate the performance of a host gene methylation marker panel (ASTN1, DLX1, ITGA4, RXFP3, SOX17, and ZNF671) in the triage of human papillomavirus (HPV)-positive women, its possible impact in a cervical cancer screening program, and the possible influence of the variation of the rate of HPV16/18 in its performance.

Materials And Methods: Cohort study in which consecutive women referred for colposcopy in an organized cervical cancer screening program had repeated HPV testing, colposcopy, and biopsies. The women that remained HPV positive at the time of colposcopy were tested with the panel of DNA methylation markers.

Evaluation of CIN2/3 Lesion Regression in GynTect DNA Methylation-Marker-Negative Patients in a Longitudinal Study.

Cervical intraepithelial neoplasia (CIN) grade 2/3 has a high spontaneous regression rate, especially among women ≤29 years of age. To reduce overtreatment, reliable prognostic biomarkers would be helpful. The main aim of this study was to analyze the negative predictive value of the methylation marker panel GynTect for lesion regression.

High Detection Rate for Non-Muscle-Invasive Bladder Cancer Using an Approved DNA Methylation Signature Test.

Introduction: Cystoscopy and transurethral resection are the current reference standard tests to diagnose and histologically confirm non-muscle-invasive bladder cancer (NMIBC). In other tumor entities (ie, colon carcinoma, cervical cancer), DNA methylation markers have been approved as diagnostic tests with high diagnostic power. In our case-control study, we used an approved molecular cervical cancer diagnostics test that includes 6 DNA methylation markers (GynTect) for the detection of bladder cancer.
