Abstract

The purpose of this study was to compare the detection of human papillomavirus (HPV) DNA with detection of mRNA. The study included 4,136 women >30 years of age. E6/E7 mRNA expression from the carcinogenic HPV types 16, 18, 31, 33, and 45 was detected by the PreTect HPV-Proofer assay, whereas the presence of HPV DNA was detected by Gp5+/6+ consensus PCR followed by type-specific PCR. A total of 4.0% had an abnormal cytologic diagnosis, 3.0% were positive by PreTect HPV-Proofer, 4.4% by type-specific PCR, and 10.4% by consensus PCR. For detection of HPV in high-grade squamous intraepithelial lesion (HSIL), no significant difference was observed between PreTect HPV-Proofer and consensus PCR. For women with a cytologic normal, atypical squamous cell of uncertain significance, and low-grade SIL diagnosis, the detection rate of HPV was significantly higher by Gp5+/6+ consensus PCR (P < 0.005) than by PreTect HPV-Proofer. Histology confirmed 14 of 23 cytologic HSIL as cervical intraepithelial neoplasia grade >2. Of these women, PreTect HPV-Proofer and type-specific PCR detected 12, whereas consensus PCR detected 13. In conclusion, for HSIL, detection of E6/E7 transcripts from HPV types 16, 18, 31, 33, and 45 are present to the same degree as DNA detected by consensus PCR. Equally important, only a small proportion of the HPV DNA-positive women with a normal, atypical squamous cell of uncertain significance or low-grade SIL diagnosis had a detectable mRNA expression. HPV E6/E7 mRNA detection by PreTect HPV-Proofer represents a new promising test as an adjunct to cytology.
