Polymerase chain reaction to detect high-risk human papillomavirus has been suggested as a gold standard for cytology. The Netherlands and Surinam were prospectively compared in regard to the proportions of Negative, Atypical Squamous Cells of Undetermined Significance, and Squamous Intraepithelial Lesion smears that had detectable high-risk human papillomavirus. For the Netherlands, 14 600 negative, 270 Atypical Squamous Cells of Undetermined Significance and 120 Squamous Intraepithelial Lesion smears were evaluated by polymerase chain reaction. For Surinam, 150 negative, 50 Atypical Squamous Cells of Undetermined Significance, and 150 Squamous Intraepithelial Lesion smears were evaluated by polymerase chain reaction. In all, 4% of Dutch and 80% of Surinamese negative smears had detectable high-risk human papillomavirus (chi2=1313, P<0.00001). In total, 41.9% of Dutch and 84% of Surinamese Atypical Squamous Cells of Undetermined Significance smears had detectable high-risk human papillomavirus (chi2=28, P<0.00001). Totally, 67.5% of Dutch and 94% of Surinamese SIL smears had detectable high-risk human papillomavirus (chi2=30, P<0.00001). The Negative: Atypical Squamous Cells of Undetermined Significance odds ratio was 0.058 for the Netherlands and 0.762 for Surinam (chi2homog=31, P<0.00001). The Negative: Squamous Intraepithelial Lesion odds ratio was 0.020 for the Netherlands and 0.255 for Surinam (chi2homog=31, P<0.00001). The Atypical Squamous Cells of Undetermined Significance: Squamous Intraepithelial Lesion odds ratio was 0.347 for the Netherlands and 0.335 for Surinam (chi2homog=0.005, P>0.75). Human papillomavirus DNA testing may not be a suitable gold standard in general because its use would make specificity and sensitivity prevalence-dependent. A new statistic, the percent of Negative pap smears with detectable high-risk human papillomavirus, is posited, which may be important if human papillomavirus DNA testing is used clinically.
Based on epidemiological and research evidence, HPV has a causal role in cervical carcinogenesis. Several HPV detection methods exist to date; the most commonly used method for detection of genital HPVs consists of nested PCR using the MY09/11 and GP5(+)/6(+) primer sets (MY/GP(+)). Recently, the PGMY09/11 primer set, a modified version of the MY09/11 primer set, was introduced for single PCR and was found to detect a wider range of HPV types. The next logical step was taken and the efficacy of nested PCR using the PGMY09/11 and GP5(+)/6(+) primer sets (PGMY/GP(+)) to detect HPV in cervical samples was evaluated. In this comparative study, nested PCR using the novel PGMY/GP(+) primer set combination was found to be more type sensitive than the nested PCR with the MY/GP(+) primer sets, detecting a wider range of HPV types, low copy HPVs, and better characterizing samples infected with multiple strains of HPV. Standardization and use of the PGMY/GP(+) PCR system could aid physicians in providing more efficient HPV screening and better treatment for patients.
