HPV 16/18 E7 oncoprotein detection as a promising triage strategy for HPV 16/18-positive patients: A prospective multicenter study with a 2-year follow up.
Objective: To explore the effectiveness of HPV 16/18 E7 oncoprotein in detecting high-grade cervical intraepithelial neoplasia (CIN) and predicting disease outcomes in HPV 16/18-positive patients.
Methods: The present study was a cross-sectional study with a 2-year follow up. We collected 915 cervical exfoliated cell samples from patients who tested positive for HPV 16/18 in gynecologic clinics of three tertiary hospitals in Beijing from March 2021 to October 2022 for HPV 16/18 E7 oncoprotein testing. Subsequently, 2-year follow up of 408 patients with baseline histologic CIN1 or below were used to investigate the predictive role of HPV 16/18 E7 oncoprotein in determining HPV persistent infection and disease progression.
Results: The positivity rate of the HPV 16/18 E7 oncoprotein assay was 42.06% (249/592) in the inflammation/CIN 1 group and 85.45% (277/324) in the CIN2+ group. For CIN2+ detection, using the HPV 16/18 E7 oncoprotein assay combined with HPV 16/18 testing, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 85.45%, 57.94%, 52.57%, and 87.95%, respectively. During the 2-year follow up, the sensitivity, specificity, PPV, and NPV for predicting persistent HPV infection were 48.44%, 58.21%, 34.64%, and 71.18% in the baseline inflammation and CIN1 group.
Conclusions: As a triage method for high-grade CIN screening in HPV 16/18-positive patients, HPV 16/18 E7 oncoprotein demonstrated a relatively high NPV, making it suitable for clinical use in triaging HPV 16/18-positive cases and potentially reducing the colposcopic referral rate. HPV 16/18 E7 oncoprotein exhibited a preferably predictive value in determining HPV infection outcomes and disease progression.
