Abstract

Fourty three patients known to hnve cervical intraepithelial neoplasia were assigned to Papanicolaou smear in five different ways, i, e, A) cotion tipped wood applieator at the pasterior vaginal fronix and the ectocervix, B) cotton tipped wood applicator at the ectocervix and the endocervical canal, C) Cytohrush at the endocervical canal, D) Cervexbrusk and E) Cyto-spatula. At the completion of cytologic study, all the subjects were done colposcopically directed biopsy and/or ECC. To evaluate the false negative rates of the cytologic test, cervical cone biopsy or hysteectorny was performed on all the patient. The false negat,ive rates were 53.5% in A) 39.5% in B), 14,0% in C), l8.6% in D), 25.6% in E) and statistical differences occurect between each group, It was also found that bleedings were most frequently endountered in E) and the encocervical cells were most frequently appeared in C). With these results, it can he stated that the rate of negative encocervical cells in the srnear were correlated with the false negative rates of cervical cytology.
