Diagnostic accuracy of squamous cervical lesions studied in spatula-cytobrush smears.

The cytologically positive cases found in 25,300 cervical smears of spatula samples and 6,168 smears prepared by combined spatula-Cytobrush sampling were analyzed. The diagnostic accuracy (the correlation between the cytologic and histologic diagnoses) was the same for both types of sampling. As to the histologic diagnosis, the rates of severe dysplasia, carcinoma in situ and squamous carcinoma in the spatula-Cytobrush group were more than twice as high as in the spatula group. In the spatula group, the majority of abnormal cells was of the mature type. In the spatula-Cytobrush group, the majority of smears contained a mixture of immature and mature abnormal cells. The more immature lesions, which are often located higher in the endocervical canal, seem to be better sampled by the Cytobrush. The results indicate that the Cytobrush reaches areas that a spatula cannot reach, resulting in a higher diagnostic efficiency.
