Human Papillomavirus (HPV) 16 and 18/45 Genotyping-Directed Follow-up of Women With Messenger RNA HPV-Positive, Cytology-Negative Cervical Screening Test Results

Abstract

Abstract Objectives In this study, we sought to correlate genotype test results for human papillomavirus (HPV) types 16, 18, and 45 with histopathologic follow-up diagnoses in patients with messenger RNA (mRNA) high-risk HPV-positive, cytology-negative results. Methods We identified 1,157 patients with mRNA HPV-positive, cytology-negative cervical screening test results between June 2015 and June 2018. Reflex HPV 16/18/45 genotype results were documented in 1,018 women aged 30 years or older, 318 of whom had follow-up within 18 months. Results Histopathologic findings of cervical intraepithelial neoplasia 2 or worse (CIN2+) were diagnosed in 14 of 122 (11.5%) patients positive for HPV 16/18/45 vs in seven of 196 (3.6%) HPV 16/18/45–negative patients. Three patients with high-risk HPV–positive, cytology-negative cervical screening test results were diagnosed with stage I cervical adenocarcinomas following early colposcopic referral and biopsy after HPV 16/18/45–positive genotype results. Conclusions Immediate reflex HPV 16/18/45 genotyping of mRNA HPV-positive, cytology-negative patients led to early colposcopic referral and histopathologic diagnoses of three difficult-to-detect, low-stage, cervical adenocarcinomas and significantly increased overall early detection of CIN2+ lesions.
