Comparison between colposcopic and cytologic findings in relation to clinical and histologic diagnoses in carcinoma in situ

: From 1977 to 1979 95 cases of carcinoma in situ had been detected at the Gynaecological Department of the Medical Academy of Erfurt. In 81 of these women there was a cytological examination before treatment. The accuracy of cytology and colposcopy was opposed the histological diagnosis in these selected cases. An agreement of colposcopy, cytology and histological findings could be found in 70 cases. In 6 cases colposcopy and in 4 cases cytology was wrong. Only in one case both examination methods failed.
