title: [Clinical evaluation of contact Nd.YAG laser therapy of dysplasia and early cancer of the uterine cervix].
abstract: For the past four years, cone and cone with cautery have been carried out by the contact Nd.YAG laser method after diagnosis with colpo.cervicoscopy in 174 cases of dysplasia and early cancer of the uterine cervix. The subjects were 82 patients with dysplasia, 75 patients with carcinoma in situ and 17 patients with microinvasive carcinoma. The cure rate based on the follow up for 6 to 50 months was 97.7%. There were 7 (4.1%) residual cases, 6 with residual mild dysplasia that required a follow up. Three cases with mild dysplasia disappeared during a follow up. In the remaining case, a semiradical hysterectomy was performed owing to Ib"occ" (8mm). Postoperative histological findings confirmed 76.2% of the preoperative findings; the rate of underdiagnosis was 23.8%. The rates of incomplete excision and underdiagnosis decreased in the cases where preoperative biopsy findings agreed with or overestimated cytologic and colpo.cervicoscopic findings. The results suggest that the laser cone is very useful as conservative therapy for early cervical neoplasia, and the cone specimen can be used to evaluate the success of the therapy and to improve future preoperative diagnosis.
