title: DNA-cytometric diagnosis of prospective malignancy in borderline lesions of the uterine cervix.
abstract: Interactive DNA cytometry was used for the diagnosis of prospective malignancy in 48 smears with borderline lesions (mild and moderate dysplasias) of the uterine cervix. In addition, 183 smears with benign squamous epithelia, 38 with carcinoma in situ and 7 with invasive squamous carcinoma were also measured. Nuclear Feulgen-DNA measurements were performed using various methods, and the resulting data were analyzed by an algorithm for a DNA-cytophotometric diagnosis of malignancy. The results were compared with the data on follow-up and subsequent histologic studies in these cases. There was no false-positive diagnosis in the 183 benign smears and only 1 false-negative diagnosis in the 76 histologically proven squamous-cell carcinomas, which yields a specificity of 100% and a sensitivity of 98.6%. The sensitivity for the detection of subsequent histologically proven malignancy in cases with cytologically mild or moderate dysplasia amounted to 97%. In 13 borderline cases, there was a mean interval of 21 months between the taking of the cytologic smear on which the DNA diagnosis of malignancy was made and the date on which the histologic confirmation of malignancy was made. In 17% of the cytologically dysplastic cases, the DNA diagnosis of malignancy was not verified by subsequent histologic investigation. These results indicate that interactive DNA cytometry is able to detect prospective malignancy in smears from borderline lesions of the uterine cervix with a high sensitivity.
