Laser conization: follow-up in patients with cervical intraepithelial neoplasia in the cone margin

Gynecol Oncol. 1990 Dec;39(3):328-31. doi: 10.1016/0090-8258(90)90261-i.


Combination laser conization was performed in 469 patients for the treatment of cervical intraepithelial neoplasia (CIN). In 58 cases (12.4%), CIN was located in the margins of the cone. Fifty-one patients with involvement of the margins were evaluated by cytologic examination, using the Ayre spatula and the Cytobrush, and by cervical biopsy and endocervical curettage (ECC). In six cases, the histologic evaluation was positive, and in three of these cases, the cytology was positive too. Hysterectomy was performed in five cases, but in only one case was a significant lesion demonstrated in the uterus. These results justify expectant, conservative management of patients treated with combination laser conization. Follow-up based on colposcopy and cytology seems sufficient.
