  • Description: Byline: Elina Virtanen, Ilkka Kalliala, Tadeusz Dyba, Pekka Nieminen, Eeva Auvinen Keywords: Cervical intraepithelial neoplasia; CIN ; diagnostics; HPV ; human papillomavirus; test performance Abstract Introduction The aim was to assess the performance of two commercial assays for the detection of high-risk human papillomavirus (hrHPV): Aptima HPV Assay (Hologic, Inc., Marlborough, MA, USA) which detects mRNA of 14 different hrHPV types, and Hybrid Capture 2 HPV DNA test (HC2; Qiagen, Gaithersburg, MD, USA), which detects the DNA of 13 different hrHPV types. Test performance was compared in the settings of a standard colposcopy clinic, among the regular patient flow. Material and methods Two separate cervical cell samples for Aptima and HC2 testing were collected from women referred to colposcopy or a cervical follow-up visit. Altogether, 481 paired samples were analyzed and all positive samples were also tested using the Aptima HPV 16 18/45 Genotype Assay. Results from the two assays were compared directly and with stratification by histology and cytology from the same sampling visit. Results The overall agreement between HC2 and Aptima assays was 92.9% (Kappa coefficient of 0.855). The sensitivity and specificity of the assays in detecting CIN2.sub.+ were 92.5 and 58.2% for HC2, and 94.0 and 59.3% for Aptima, respectively. No significant differences between the assays were found (p-values >0.5). Both assays detected all CIN3 (n = 30) and carcinoma (n = 2) cases. Conclusions The mRNA-based Aptima assay and the extensively studied DNA-based HC2 test performed equally well in detecting high-grade cervical lesions. Our data contribute to the growing evidence base indicating that the mRNA-based Aptima assay could be used for the triage of patients with HPV-associated cervical disease.
