Abstract: | ObjectivesWe aimed to assess the performance of DH3 human papillomavirus (HPV) assay, a newly developed hybrid capture technique that detects 14 high-risk HPVs with type 16/18 genotyping, as a primary test in cervical cancer screening.MethodsIn total 11,356 Chinese women aged 21–65 years participated in a cervical cancer screening programme using cytology (Thinprep, Hologic) and HPV testing (Cobas 4800 Test, Roche). Residual samples were used to detect HPV by DH3 HPV.ResultsIn total 10,669 women with valid results were included in the study. Of those, 135 were diagnosed as CIN2+, and 83 were diagnosed as CIN3+; 1056 women (9.9%) were DH3 HPV-positive and 255 (2.4%) of those were 16/18-positive, while 990 (9.3%) women were Cobas HPV-positive and 243 (2.3%) of those were 16/18-positive. DH3 HPV was non-inferior to Cobas HPV in identifying CIN1− and CIN2+ using predetermined thresholds (both p < 0.001). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of DH3 HPV were 93.3% (95% confidence interval [CI] = 87.7–96.9), 91.2% (95%CI = 90.6–91.7), 12.0% (95%CI = 10.1–14.1) and 99.9% (95%CI = 99.8–100), respectively, similar to those of Cobas HPV (91.1%, 95%CI = 85.0–5.3; 91.8%, 95%CI = 91.2–92.3; 12.5%, 95%CI = 10.5–14.7; and 99.9%, 95%CI = 99.8–99.9, respectively), in identifying CIN2+ (all p > 0.05). When DH3 HPV and Cobas HPV were respectively used as primary testing in screening strategy, the performance of two strategies were similar in identifying CIN2+. The results were similar in identifying CIN3+.ConclusionOur data suggest that DH3 HPV performs similarly to Cobas HPV in identifying high-grade CIN in cervical cancer screening. |
