[Diagnosis and treatment of dysplasia of the uterine cervix].

The accuracy of diagnosis and the results of treatment for dysplasia of the uterine cervix are analyzed. Three hundred and thirty-seven cases of mild, 231 of moderate and 200 of severe dysplasias have been treated at Kitasato University Hospital. By cytology 40.4% of mild, 74.5% of moderate and 89.0% of severe dysplasias were judged suspicious or positive, and the accurate cytopathological detection rate was 19.8%, 16.1% and 60.1%, respectively. Abnormal colposcopic findings such as M, P and W were observed in more than 95% of cases with dysplasia. The area of abnormal findings tends to be large as the lesion becomes more severe. Mild dysplasia progressed to cervical cancer in 1.5%, moderate dysplasia in 2.4% and severe dysplasia in 9.4%. Conservative therapy by laser vaporization or conization was used for 31 mild, 96 moderate and 114 severe dysplasias. The cure rate of each dysplasia was 100%, and pregnancy following laser therapy was encountered in 28 cases without abnormal course. It is concluded that colposcopy is more useful in diagnosis of mild and moderate dysplasia than cytology, and conservative laser treatment is an effective method for dysplasia.
