ObjectiveTo study the proper treatment of the patient with positive margins after cervical conization. MethodsA total of 220 cervical conizations were performed in the department of obstetrics and gynecology in Conception Hospital in Marseille in France from January 1, 1996 to June 30, 1998. Among them, we studied 73 patients, who had positive margins, by using cervical cytology examination and colposcopy in 3,6,12,18 and 24 months after cervical conization. Results7 cases of cancer invasive were treated with radiotherapy; 17 underwent a second conization or hysterectomy, among whom 8 had residual disease of positive margins near internal orifice of uterus (residual rate, 47. 06 ％ ); 40 remained follow- up; but 9 were lost.ConclusionCytology and colposcopy are effec- tive in the surveillance of patients with positive margins after cervical conization, and can give the indica- tion of the second conization.
