From all women included in the study, a liquid-based cytology sample was obtained; this was tested via HPV DNA test, E6\/E7 HPV mRNA test, and p16 immunostaining. The data were classified by the LVQ-NN into two groups: CIN-2 or worse and CIN-1 or less. Half of the cases were used to train the LVQ-NN; the remaining cases (test set) were used for validation. Out of the 1258 cases, cytology identified correctly 72.90% of the CIN-2 or worst cases and 97.37% of the CIN-1 or less cases, with overall accuracy 94.36%. The application of the LVQ-NN on the test set allowed correct classification for 84.62% of the cases with CIN-2 or worse and 97.64% of the cases with CIN-1 or less, with overall accuracy of 96.03%. The use of the LVQ-NN with cytology and the proposed biomarkers improves significantly the correct classification of cervical precancerous lesions and\/or cancer and may facilitate diagnosis and patient management.<\/jats:p>","DOI":"10.1155\/2012\/303192","type":"journal-article","created":{"date-parts":[[2012,10,3]],"date-time":"2012-10-03T21:04:00Z","timestamp":1349298240000},"page":"1-8","source":"Crossref","is-referenced-by-count":25,"title":["Identification
