Abstract

This study was designed to evaluate the Clinichip HPV test, a new DNA test that detects carcinogenic human papillomavirus (HPV) rapidly by loop-mediated isothermal amplification and performs genotyping of all 13 carcinogenic types using automated DNA chip technology with an assay time 2.5. h. Using this test, 247 Japanese women (109 with normal cytology, 43 with cervical intraepithelial neoplasia grade 1, 60 with cervical intraepithelial neoplasia grade 2/3 and 35 with invasive cervical cancer) were tested for carcinogenic HPV genotypes. The results were compared to those obtained by the polymerase chain reaction-amplified DNA sequencing using 13 type-specific primers. Overall, there was very good agreement for the detection of carcinogenic HPV between the Clinichip test and direct sequencing, with 95.5% total agreement and a kappa value of 0.91. Comparison of the detection of individual HPV types shows that the overall agreement was also high (range: 96.8-100%). In women with cervical intraepithelial neoplasia grade 2 or worse, the detection rate of carcinogenic HPV was 95.7% by both the Clinichip test and the direct-sequencing method, indicating complete agreement between the two methods. In conclusion, it was found that the Clinichip test is a promising new laboratory method for genotyping of carcinogenic HPV.
