[Therapy and therapeutic results in carcinoma-in-situ- of the uterine cervix].

348 cases of carcinoma in situ are reported, which were diagnosed, without exception, by conization from 1966 to 1971. The atypical changes could be removed without leaving any detectable malignant cells in situ in 226 patients (65 per cent). These cases did not need any further therapy. In 45 cases (12,9 per cent) was doubtful if the conization could be performed without leaving malignant cells. In 77 cases (22,1 per cent) the conization was done leaving malignant cells in situ. 49 women of this group had a continued treatment, the vast majority was hysterectomized. All the other cases were strictly controlled. The 5-year healing quotient was 91,7 per cent. 7,1 per cent of the patients have not been heard of again. Only 3 patients (0,9 per cent) suffered a recurrence. They belong, without exception, to the control group in which the carcinoma in situ could not be primarily removed without leaving malignant cells in situ. The significance of an exact method of conization and a careful histotechnical perparation of the specimens in serial sections is especially pointed out. The necessity of a continued treatment by means of hysterectomy with vaginal cuff is stressed in carcinoma in situ which could not be removed without leaving malignant cells in situ.
