title: [Establishing guidlines for dealing with mild dysplasia through cytology and colposcopy (follow up study)].
abstract: 230 cases of mild dysplasia, detected in examinations for cancer of the uterus, were followed up cytologically, and colposcopically for more than 2 and a maximum of 10 years, and the following results were obtained: Mild dysplasia resulted in regression in 169 cases (73.5%), persistence in 46 cases (20.0%), and progression in 15 cases (6.5%). Out of the group with progression, 10 cases (4.3%) developed into carcinoma in situ or microinvasive carcinoma. The average period required for the progression was 54.8 months. The combined use of cytology and colposcopy is useful for diagnosis and follow up of mild dysplasia. In the combined use of cytology and colposcopy, it is appropriate to evaluate the outcome (progression or regression) of mild dysplasia 2 years after detection. The transformation ratio at the time of the initial examination was in many cases higher in the progression group than in the regression group. In the progression group an increase in the transformation ratio was noted in all cases, and it appears that it is also necessary to pay attention to changes in the transformation ratio, in addition to the grading of the findings.
