Conservative treatment for cervical cancer IA1: four cases report.

Cervical carcinoma IA1 is defined as invasive cervical cancer with measured invasion of the stroma no greater than 3 mm in depth and no wider than 7 mm in diameter. It has been managed by extrafascial or modified radical hysterectomy. For young female patients who want to preserve future fertility, conservative treatment using therapeutic conization should be considered. In Taiwan, there has been little information about conservative treatment for cervical carcinoma IA1. We present 4 cases of young women with cervical carcinoma IA1 treated by conization alone. Pathological reports of all specimens demonstrated squamous cell carcinoma with free margins, stroma invasion less than 3 mm and no evidence of lymphovascular space invasion (LVSI). After 5-year follow-up with pelvic examination, pap smear, and colposcopy, there was no evidence of disease recurrence. We believe that conservative treatment for cervical carcinoma IA1 without LVSI is appropriate for selected patients to preserve future fertility.
