Oncogenic human papillomavirus (HPV) infection is the most important risk factor in cervical carcinogenesis with high viral load, viral integration into the host genome, and gain of the telomerase-related genes TERT and TERC being factors associated with progression to cancer. A recently developed multiparameter HPV MLPA-assay (Theelen et al. Int J Cancer 2009, Epub Aug 26) that allows the simultaneous assessment of these factors was applied to a series of normal and (pre)malignant frozen uterine cervical samples, and tested for its ability to identify high grade cervical lesions with both high sensitivity and specificity.

A total of 67 cervical samples from normal cervix, as well as different (pre)malignant stages was analysed by the MLPA-assay and validated by quantitative PCR, the PapilloCheck, and fluorescence in situ hybridization for the individual parameters.

Only 5 out of 37 (14%) normal samples or low grade cervical lesions (CIN1 and condyloma) showed either a HPV16 viral load higher than 25 copies per cell, viral integration, and/or gain of one of the telomerase related genes, whereas for the high grade cervical lesions (CIN2/3 and squamous cell carcinoma) one or more of these parameters were found in 25 out of 30 cases (83%). As a result, the HPV MLPA-assay combines a sensitivity of 83% with a specificity of 86% in frozen cervical specimens, making it a valuable screening tool for cervical (pre)neoplasia.
