Class ? Versus Class ? Radical Hysterectomy In Stage IB1 Cervical Cancer:A Propensity Score Matching Analysis

Objective: To compare the long-term oncological outcomes of Class ? hysterectomy and Class ? radical hysterectomy for treatment of stage IB1 cervical cancer after propensity score matching based on SEER database.Methods: A retrospective analysis was performed on patients with stage IB1 cervical cancer who underwent Class ? hysterectomy or Class ? radical hysterectomy in SEER database from January 2004 through December 2010 by PSM analyses.Five-year survival outcomes were assessed by using Kaplan-Meier model.Results:1.429 patients underwent Class ? hysterectomy and 408 patients underwent Class ? radical hysterectomy with stage Ib1 cervical cancer were selected.2.After propensity-matched,each group has 351 patients.Before matched the age at diagnosis(years),marital status,grade have significant differences.These differences resolved after propensity matching.3.Class ? and Class ? group had similar 5-year overall survival rates(OS)(87.2% vs 89.2%,P = 0.376).Conclusions: Class ? hysterectomy is an oncological safe alternative to Class ? radical hysterectomy in treatment of stage IB1 cervical cancer.
