Abstract
In order to compare the detection rate of uterine cervical neoplasia in two scraping methods, spatula and cotton tipped applicator, 4, 255 women were screened using both methods simultaneously at Wakayama Rosai Hospital from 1978 to 1980.
With the spatula scraping method, ten cases of frank invasive cancer, fifteen cases of microinvasive cancer, twenty three cases of carcinoma in situ and twenty three cases of severe dysplasia were detected. On the other hand, with the cotton tipped applicator method, ten cases, fifteen cases, twenty cases and fifteen cases were found respectively.
A significant difference was found in the detection ratio of carcinoma in situ and dysplasia: that of carcinoma in situ was 87.0% (20/23) with the cotton tipped applicator method and 100% (23/23) with the spatula scraping method, and that of severe dysplasia was 69.6% (16/23) and 100% (23/23) respectively. There was no difference in the detection ratio of invasive cancer (10/10) and microinvasive cancer (15/15).
Accuracy of cytology with both methods was studied in 96 cases operated for uterine cervical cancer in our hospital.
Accuracy of cytology in frank invasive cancer was 81.2% with the cotton tipped applicator method and 81.0% with the epatula scraping method, respectively 61.9% and 75.0% in microinvasive cancer, 69.6% and 80.6% in carcinoma in situ, 48.2% and 79.2% in severe dysplasia.
The spatula scraping method proved more accurate than the cotton tipped applicator method in cytological diagnosis of uterine cervical neoplasia.
