Abstract
The World Health Organization recommends human papillomavirus (HPV) testing for cervical screening. Extended genotyping can identify the highest-risk HPV-positive women. An inexpensive, rapid, mobile isothermal amplification assay (ScreenFire HPV RS test) was recently redesigned to yield four channels ordered by cancer risk (ie, hierarchical approach): HPV16, HPV18/45, HPV31/33/35/52/58 and HPV39/51/56/59/68. Stored specimens from 2076 women (mean age 30.9) enrolled in a colposcopy clinic, with high HPV prevalence, were tested with ScreenFire. We calculated hierarchical channel positivity and non-hierarchical channel and type positivity, according to histologic diagnosis (256 cancer, 350 cervical intraepithelial neoplasia [CIN]3, 409 CIN2, 1020 < CIN2) and known virologic reference results (Linear Array and TypeSeq). Additionally, we analyzed ScreenFire time-to-positive up to 60 min by channel and histology. Overall clinical sensitivity for CIN3+ was 94.7% (95% confidence interval 92.6-96.4), similar to Linear Array (92.3, 89.7-94.3) and TypeSeq (96.0, 93.9-97.6). Sensitivity was high for all types and channels. The hierarchical approach was well in line with HPV typing and histologic diagnosis, prioritizing higher risk women having HPV16 and precancer. For HPV16, time-to-positive was shorter in women with precancer. ScreenFire showed excellent agreement with research reference typing tests and detection of CIN2+. Risk-based type results could help guide clinical management of HPV-positive women. Time-to-positive combined with genotyping might be useful. ScreenFire is rapid, mobile, relatively inexpensive and designed for implementation of HPV-based screening and management, including in lower-resource settings. Further validation in screening by self-sampling and practical effectiveness merit evaluation.

Abstract
PURPOSE This study aims to assess the detection of cervical intraepithelial lesions grades 2 and 3 (CIN2-3) at 1 year after treatment with thermal ablation among human papillomavirus (HPV)–positive and visual inspection with acetic acid (VIA)–positive women. METHODS All women screened and triaged for cervical cancer at four government health facilities in Honduras who were eligible for ablative treatment were enrolled and treated with thermal ablation. Women with confirmed CIN2-3 and a subset of women with CIN1/normal diagnoses at baseline were evaluated at 12 months. Follow-up procedures included HPV testing (careHPV), VIA, directed biopsy (if VIA-positive), and Papanicolaou test (if HPV positive, VIA negative). Outcomes at 1 year included histologic or cytologic assessment of CIN lesions among those with any abnormal test. RESULTS Among the 319 women treated with thermal ablation, baseline histologic diagnoses were available for 317. Two (0.6%) had invasive cancer, 36 (11.4%) had CIN3, 40 (12.6%) had CIN2, and 239 (75.4%) had CIN1/normal histology. Among the 127 women eligible for follow-up, 118 (92.9%) completed all study procedures at 1 year. Overall, 98 (83.1%) had no evidence of CIN2-3 or persistent low-grade infection, 13 (11.2%) had CIN1/atypical squamous cells of undetermined significance, six (5.1%) had CIN2/high-grade squamous intraepithelial lesion, and 1 (0.8%) had a persistent CIN3. No adverse events associated with thermal ablation at 1 year were registered. CONCLUSION A high proportion of women had no evidence of CIN2-3 at 1 year after thermal ablation treatment. Thermal ablation is an alternative to cryotherapy that may facilitate greater treatment coverage and prevent unnecessary deaths from cervical cancer.
