 note = {Specific types of human papillomaviruses (HPVs) are closely associated with the development of genital carcinomas. We previousy reported a PCR method which amplifies the E6E7 sequence from 6 different high-risk genital HPVs (HPV16, 18, 31, 33, 52 and 58) (J Gen Virol 1991, 72 : 1039-1044.). To amplify broader types of genital high-risk HPVs, we have modified our consensus primers by extending 9 nucleotides at the 3 end of the sense primer and changing 5 nucleotides at the 5 end of the anitisense primer. Genotype diag-nosis was carried out by AvaII plus Rsal digestion. This modified PCR method enabled the detection of trace levels of at least 11 types of genital high-risk HPVs (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56 and 58), at subpicogram to sub-nanogram amounts of cloned DNA, amplified after the consensus PCR. We applied this method to analyze 155 cervical scrapes from patients who had been diagnosed with premalignant or malignant cervical lesions. HPVs were detected in 63.0% of mild dysplasia (17/27), 100% of moderate dysplasia (all 12 cases), 91.7% of severe dysplasia (11/12), 95.8% of carcinoma in situ (23/24), and 80.0% of invasive cervical cancer (52/65). HPV16 was present predominant-ly (60.9%), followed by HPV58 (153%), HPV52 (13.9%), HPV31 (13.0%), HPV18 (6.1%), HPV35 (2.6%), HPV51 (2.6%), HPV56 (2.6%), HPV33 (1.7%) and HPV39 (1.7%). Five cases contained unclassified types (4.3%). The results indicate that this modified E6E7 consensus PCR method provides a quick and easy way to detect and diagnose genotypes of the high-risk genital HPVs from scraped cells.},
