Article Abstract
Objective: To assess the clinical values of extended human papillomavirus (HPV) genotyping in triage of high-risk HPV-positive women, focusing on the trade-off between cervical precancer detections and colposcopy referrals.
Methods: A bivariate random-effects model was used to estimate the diagnostic accuracy of primary HPV screening with following triage strategies to detect cervical precancers: (i) partial genotyping for HPV16/18 combined with cytological testing at atypical squamous cells of undetermined significance threshold (used as the comparator), (ii) genotyping for HPV16/18/58/52, (iii) genotyping for HPV16/18/58/52/33, (iv) genotyping for HPV16/18/58/33/31, (v) genotyping for HPV16/18/58/52/33/31, and (vi) genotyping for HPV16/18/58/52/33/31/39/51. Internal risk benchmarks for clinical management were used to evaluate the risk stratification of each triage strategy.
Results: A total of 16,982 women (mean age 46.1 years, range 17-69) were included in this analysis. For CIN3+ detection, triage with HPV16/18/58/33/31 genotyping achieved lower positivity (6.85% vs. 7.35%, p = 0.001), while maintaining similar sensitivity (91.35% vs. 96.42%, p = 0.32) and specificity (94.09% vs. 93.67%, p = 0.56) compared with the comparator strategy. Similar patterns were observed for CIN2+ detection. Women with a positive HPV16/18/58/33/31 genotyping test had high enough risk for CIN3+ for colposcopy referral, while the risk for women with a negative test was below the 1-year return decision threshold according to internal benchmarks.
Conclusions: Our findings suggested extended HPV genotyping is of potential to be used as a triage technique integrated into HPV-based cervical cancer screening, leading to reduced need for colposcopy referral while maintaining similar disease detection and efficient risk stratification.

Background: Cervical cancer is primarily caused by the Human Papillomavirus (HPV). Despite all the advances in early detection of HPV infection, cervical cancer remains one of the most common types of cancer in women, with a high presence in Latin America. We previously reported on the prevalence of HPV in the Coquimbo region, so the objective of this study was to determine the frequency of HPV in women in the Antofagasta and Arica regions of northern Chile.

Screening for high-risk human papillomavirus (hrHPV) infection is essential for cervical cancer prevention. However, developing a simple, portable, and low-cost hrHPV genotyping method remains challenging, particularly in resource-limited settings. Herein, we present an innovative amplification-free, point-of-care hrHPV genotyping platform integrating CRISPR/Cas12a with alkaline phosphatase (ALP)-mediated surface plasmon effect.

HPV E6 is a multifunctional oncoprotein that drives tumorigenesis and is best known for bridging the ubiquitin ligase E6AP (UBE3A) and p53 into a complex that leads to proteasome mediated destruction of p53. We developed small molecule inhibitors that covalently bind to cysteine-51 (Cys-51) in HPV16 E6.

Squamous cell carcinoma (SCC) of the vulva is caused by disturbances in the proliferation and differentiation of the squamous epithelium, which can be associated with human papillomavirus (HPV) infection. Vulvar SCC is usually caused by high-risk HPV types, although there are some cases that are caused by low-risk HPV types. The clinical manifestations of vulvar SCC vary, one of which can resemble anogenital warts.

Objective: This study primarily aimed to investigate human papillomavirus (HPV) infection in males and to evaluate its effect on semen parameters, fertility and partner HPV infection status.
Methods: A total of 624 men who visited the West China Second Hospital of Sichuan University between October 1, 2019, and September 30, 2023, were included. HPV DNA was detected in exfoliated cells from the male genitalia using polymerase chain reaction (PCR) and reverse membrane hybridization to analyze the relationship between HPV infection and semen parameters.
