OBJECTIVE: This study was conducted to compare the correlation between the Pap smear and colposcopy findings in postmenopausal Mexican women.
MATERIAL AND METHODS: Observational, Retroelective, longitudinal, descriptive study, all menopausal women who consulted for pap smears and colposcopy performed was studied.
RESULTS: 119 patients were evaluated. 72 % of pap smears were negative to human papilloma virus, 29 (24%) had a low-grade lesion and 4 (4%) had a high-grade lesions. In the colposcopic study: 31 studies (26%) report low-grade intraepithelial lesion and 2 cases (2%) high-grade lesion. The histopathological biopsy reported one invasive cervical cancer (2.43%) and 20 cases of low-grade lesions (48.7%). cytology had a sensitivity of 85.3% and specificity of 56.09% with a false negative rate of 14.3%, a positive predictive value of 66.03 % and a negative predictive value of 79.31%. Colposcopy: sensitivity= 82.92%, specificity = 56.09% with a false negative rate of 17.07% positive predictive value of 65.38% and a negative predictive value of 76.66%.
CONCLUSIONS: The correlation between Pap smear and colposcopy shows that the diagnosis of low and high grade lesions differs only by 2%, therefore indicates adequate sensitivity for diagnosis. In this population of women routine gynecological tests most be performed.
