Abstract

A high-throughput matrix-assisted laser desorption ionisation-time of flight (MALDI-TOF) mass spectrometry (MS)-based method was here developed to genotype 16 high-risk human papillomavirus (HPV) types in cervical cytology specimens. This method was compared to a commercial kit, the Inno-LiPA HPV genotyping assay, which detects a broad spectrum of HPV types. HPV DNA was assessed by the two methods in a total of 325 cervical cytology specimens collected in PreservCyt® solution. The overall agreement was almost perfect (Cohen's k=0.86) in term of positive and negative cases. Indeed, HPV types 16, 35, 56 and 66 showed the highest agreement values (>0.80). The highest agreement values (K >0.80) were found for all 16 HPV types in single infections, but only for HPV 16, 35, 45 and 56 in multiple infections. In conclusion, the high-throughput MS-based method developed here is well-suited for broad spectrum HPV genotyping in large-scale epidemiological studies.
