OBJECTIVE: The objective of this study was to determine the role of the extent of the radicality in the treatment of stage IB-IIA cervical carcinoma with respect to survival, pattern of relapse, and morbidity.

METHODS: Two-hundred forty-three patients with cervical carcinoma (FIGO stages IB and IIa) were enrolled in a prospective randomized study comparing two types of radical hysterectomy (Piver-Rutledge-Smith class II and class III) between April 1987 and December 1993, and 238 are evaluable. Disease-free survival, overall survival, pattern of recurrences, and morbidity were the endpoints of this study.

RESULTS: Mean operative time was significantly (P = 0. 05) shorter in the group of patients undergoing class II hysterectomy (135 min vs 180 min), whereas mean blood loss (530 ml vs 580 ml) and number of patients requiring transfusions (35% vs 43%) were similar in the two arms of treatment. Complications unrelated to the extent of the surgical dissection and mean postoperative stay were similar in the two arms of treatment. Late morbidity was significantly lower in patients in the class II arm (especially urologic morbidity, 13% vs 28%). Postoperative radiotherapy was administered to 64 patients (54%) in class II and to 65 patients (55%) in the class III arm. Recurrence rate (24% class II vs 26% class III) and number of patients dead of disease (18% class II vs 20% class III) were not significantly different in the two groups of treatment. Overall 5-year survival was 81 and 77% and disease-free survival was 75 and 73%, respectively. Multivariate analysis confirms that survival does not depend on the type of operation.

CONCLUSIONS: Class II and class III radical hysterectomies are equally effective in surgical treatment of cervical carcinoma, but the former is associated with a lesser degree of late complications.
