Abstract

Background: We investigated whether pelvic or para-aortic lymphadenectomy increases the prognostic value of the revised 2009 FIGO staging system in patients with endometrial cancer (EC). Methods: We reviewed 786 patients with EC from six tertiary medical centers between July 1996 and June 2008. All patients were classified according to the 1988 FIGO staging system: IA (n = 234); IB (n = 270); IC (n = 109); IIA (n = 35); IIB (n = 29); IIIA (n = 37); IIIB (n = 3); IIIC (n = 69), and the revised 2009 FIGO staging system was also applied to divide them: IA (=542); IB (=125); II (n = 29); IIIA (n = 18); IIIB (n = 3); IIIC1 (n = 43); IIIC2 (n = 26). Prognostic values between the 1988 and the revised 2009 FIGO staging systems were compared by multivariate Cox's proportional hazard analysis. Results: The 1988 FIGO stage IC, IIB, IIIA + IIIB and IIIC, and the revised 2009 FIGO stage IB, II, IIIA + IIIB and IIIC2 diseases were prognostic factors for poor PFS, whereas the 1988 FIGO stage IIB and IIIC, and the revised 2009 FIGO stage II, IIIA + IIIB and IIIC2 diseases were unfavorable prognostic factors for OS. Although these results were similar to those in 595 patients who underwent pelvic or para-aortic lymphadenectomy, the revised 2009 FIGO stage IIIC1 disease was an additional prognostic factor for poor PFS and OS (adjusted HRs, 4.19 and 11.25; 95% CIs, 1.39-12.60 and 2.23-36.74). Conclusions: The revised 2009 FIGO staging system had a higher prognostic value than the 1988 FIGO staging system, and pelvic or para-aortic lymphadenectomy increased the prognostic value of the revised 2009 FIGO staging system for EC.
