The sensitivity of this ELISA method for the identification of Title Loaded From File high-risk lesions was 84 , and the specificity was 87 [52]. In agreement with these data, the specificity of CDKN2A mRNA detection, which encodes p16, in screening for CIN2+ was very close (93 , Table 4). Two new markers identified in this work (CDKN3 and NUSAP1), along with CDKN2A, showed a high specificity (93 ) and PPV (93.4 ); therefore, they might be good candidates to use with HC2 as a first-line strategy in a screening program. The scope of this study was to perform a feasibility evaluation to ascertain whether determining the mRNA levels of novel genes in cervical samples would allow for the identification of high-grade CIN or invasive lesions with high sensitivity and specificity. However, the potential sensitivities reported in this analysis are most likely overestimated compared to those likely to be found in clinical practice, as those with CIN2+ have a higher proportion of cervicalcancer (which is easy to identify) than that expected in any screening setting. In contrast, the specificity seems to be underestimated, given that a large proportion of CIN1- had CIN1. Therefore, we did not expect to obtain conclusive data on the sensitivity, specificity or predictive values of the assays. Further studies are needed to determine the levels of CDKN3, NUSAP1, and CDC20 mRNA or protein in cervical samples from a screening population to obtain information about the predictive values and to define the optimal trade-off between sensitivity and specificity for the detection of CIN2+. PRC1, CCNB2, and SYCP2 are markers exclusively associated with invasive cervical cancer. Together with NUSAP1, CDKN3, and CDC20, these genes represent potential specific targets for the treatment of advanced CC, particularly CDKN3, which was found to be associated with poor survival. These genes encode proteins involved in the cell cycle, specifically in the M phase (mitosis and cytokinesis).
