To evaluate the efficacy of cold knife conization with electrocauterization and the feasibility of conservative management in patients with stage IA1 carcinoma of the cervix according to margin status after conization.


Medical and histopathological records of 108 patients with stage IA1 cervical carcinoma were reviewed retrospectively. Patients underwent cold knife conization with electrocauterization or conization followed by hysterectomy. Disease recurrence was defined as a histologic diagnosis of cervical intraepithelial neoplasia (CIN) 2 or higher grade lesion.


Forty patients underwent conization followed by hysterectomy; of 27 women with positive margins, 14 (35%) had a residual lesion. Sixty-eight patients underwent conization without further surgical intervention. Forty patients had a negative resection margin without recurrence, while 28 had a positive resection margin: positive exocervical (n=11), positive endocervical (n=17). Among these, there were 7 cases of recurrence: positive exocervical (n=1); positive endocervical (n=6).


Cold knife conization with electrocauterization appears to be a safe treatment option for patients with stage IA1 cervical carcinoma if careful follow-up is guaranteed for patients with CIN 3 exocervical resection margins. However, patients with CIN 3 endocervical resection margins should be managed surgically with repeat conization or hysterectomy.
