In the management of patients with advanced-stage pure endometrioid-type endometrial cancer (E-EC), such as positive lymph nodes (stage III) or stage IV, treatment options are severely limited. This article aims to investigate the outcome of women with FIGO III-IV E-EC (based on FIGO 2009 system). The retrospective cohort study, based on the Taiwanese Gynecologic Oncology Group (TGOG-2005), enrolled patients undergoing staging surgery to have a pathologically confirmed FIGO III-IV E-EC from 22-member hospitals between 1991 and 2010. This cohort included 541 patients (stage III, n=464; stage IV, n=77). Five-year overall survival (OS) was 70.4%. Median progression-free survival (PFS) was 43 months (range 0-258 months) and median OS was 52 months (range 1-258 months). Multivariate analysis showed that FIGO stage, >1/2 myometrial invasion (hazard ratio [HR] 1.53, 95% confidence interval [CI] 1.12-2.09; P=0.007), histological grade 3 (HR 2.0, 95% CI 1.47-2.75; P<0.001), and metastases of pelvic and para-aortic lymph nodes (PLN and PALN) (HR 2.75, 95% CI 1.13-6.72; P<0.001) were independent risk factors for PFS. FIGO stage, >1/2 myometrial invasion (HR 1.89, 95% CI 1.34-2.64; P<0.001), and histological grade 3 (HR 2.42, 95% CI 1.75-3.35; P<0.001) influenced OS. Complete dissection of PLN and PALN (HR 0.27, 95% CI 0.16-0.45; P<0.001, and HR 0.14, 95% CI 0.08-0.26; P<0.001) and the following paclitaxel-based therapy (HR 0.61, 95% CI 0.79-0.92; P=0.017, and HR 0.48; 95% CI 0.31-0.75; P=0.001) provided the better PFS and OS, respectively. In management of women with FIGO III-V E-EC, combination of complete staging surgery (complete dissection of PLN and PALN is included) and the following paclitaxel-based therapy could provide the better chance to survive. Patients with tumor >1/2 myometrial invasion and histological grade 3 are risky for disease-related mortality.
