An epidemiologic study of Papanicolaou smear data at Ain-Shams University hospitals

This study is designed to find out the association between some risk factors for cancer cervix and the sensitivity and specificity of pap smear test. Data from the Cyto-Diagnostic Unit of Department of Obstetrics and Gynaecology Ain-Shams University are used. Women included in the study are those, who have had both cytology and directed biopsies irrespective of the cytology results. 757 women from 1981-1989 met that criteria and data for them are retrieved from computer files. It is found that there is association between age of women (P less than or equal to 0.05 for sensitivity and specificity), parity (P less than or equal to 0.05 for sensitivity, P greater than 0.05 for specificity), age at marriage (P less than 0.05 for sensitivity, P greater than 0.05 for specificity), and duration of marriage (p greater than 0.05 for sensitivity, P less than 0.05 for specificity), and the sensitivity and specificity of Papanicolaou smear.
