ABSTRACTIntroduction. Cervical cancer is the second most common cancer in Latin American women and the second cause of death. In Mexico in the past decade, 48.761 deaths were reported from this reason. Infection with human papillomavirus causes the appearance of cervical cancer, since it has identified in 99.7% of cervical carcinomas. Objective. Determine the diagnostic accuracy of cytology, colposcopy and histology for the detection of cervical intraepithelial lesions. Material and methods. Descriptive, retrospective and analytical study in a sample of 673 patients treated at the pathology service at the Women’s Hospital, Ministry of Health from January 1st 2010 until December 31st 2011. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were calculated. Results. The cytology-histology, sensitivity 39%, specificity 70%, positive predictive value 86%, negative predictive value 18%. Colposcopy and histology, sensitivity 99%, specificity 43%, positive predictive value 89.9% and negative predictive value 90%, diagnostic accuracy 44% for cytology and colposcopy 89%. Conclusions. There is not a single diagnostic method (cytology, colposcopy, including guided biopsy), which promotes an accurate diagnosis of intraepithelial lesions, but a correlation greater than 90% is well accepted.
