During the last 3 decades, the standard treatment for stage Ia2-Ib1 cervical cancer has been Piver-Rutledge class II or III radical hysterectomy. However, this surgery is associated with a high rate of urologic morbidity.

To determine the efficacy of class I radical hysterectomy compared with class III radical hysterectomy in terms of morbidity, overall survival, and patterns of relapse in patients with Ia2-Ib1 cervical cancer undergoing primary surgery.

Material and methods
A total of 101 patients with stage Ia2-Ib1 cervical cancer < 2 cm were randomized to class I and class III hysterectomy groups. Clinical, pathologic, and follow-up data were prospectively collected. Univariate analysis was carried out. Of the total patients, 45 were randomized to class I surgery and 56 to class III surgery. No significant differences were observed in terms of pathologic findings or adjuvant treatment (p > 0.05). The morbidity rates were higher after class III surgery.

The difference in recurrence rate between the class I and class III groups was not statistically significant (p > 0.05). The 5-year overall survival rate was 93% and 91%, respectively (p > 0.05). There were no significant differences in terms of recurrence rate or overall survival among patients with stage Ia2-Ib1 cervical cancer < 2 cm who underwent class I or radical (class III) hysterectomy. Morbidity was proportional to the extent of radicality.

These data confirm the need for reducing surgical radicality in the treatment of patients with early cervical cancer, by tailoring the extent of resection according to the extent of disease.
