title: [Treatment of neoplasms of the uterine cervix by CO2 laser].
abstract: CO2 evaporation was undertaken on 241 patients with cervical intraepithelial neoplasia. The results obtained six weeks after the treatment revealed disappearance of 89.6% of the lesions, and the therapeutic results obtained one year after reirradiation were favorable; 97.5% of the lesions had disappeared. However, not a few patients have some neoplasms of the uterine cervix to which this therapy is not applicable. Therefore, conization was started for treatment combined with diagnosis by means of CO2 laser. The therapeutic effect has been studied in 64 patients to date. Five patients with carcinoma of stage Ia and four patients with endoepithelial carcinoma who had undergone hysterectomy after conization were examined for the presence or absence of residual lesions. The lesions had disappeared completely. The remaining 64 patients who had not undergone hysterectomy are now under follow-up study, and a residual lesion was observed in only one patient, suggesting the possibility of treating a large number of CIN patients by evaporation combined with conization.
