Abstract

Objectives

Para-aortic lymph node involvement in women with endometrial carcinoma (EC) is a poor prognostic factor. Many studies have included women with stage IIIC 2 in cohorts of patients with advanced stage disease. The aim of this study was to analyze survival outcomes and patterns of failure in women with solely stage IIIC 2 EC.

Methods

We identified women with FIGO stage IIIC 2 EC who underwent surgical staging at our institution. In addition to descriptive analyses of patient demographics, tumor characteristics, and adjuvant treatment received, univariate log-rank analyses and Cox regression multivariate analyses (MVA) were performed to identify predictors of recurrence-free (RFS), disease-specific (DSS) and overall survival (OS).

Results

A total of 72 women were included in this study cohort. The median follow-up time was 43 months. The median number of positive para -aortic lymph nodes was one. Of the 61 women (84.7%) who received adjuvant therapy, 40 women (65.6%) received chemotherapy and radiation therapy (CRT), 17 women (27.9%) received chemotherapy alone (CT), and only 4 women (6.6%) received radiation therapy alone. Thirty-seven women (51.4%) experienced disease recurrence. Distant metastasis was the most common pattern of failure (73%). Five-year RFS, DSS, and OS were 48%, 51%, and 48%, respectively. Due to small study size, our exploratory multivariate analysis demonstrated that histologic grade was the only significant prognostic factor for DSS ( p = 0.03) and OS ( p = 0.02). The type of adjuvant therapy did not sustain its independent predictive significance for RFS, DSS and OS.

Conclusions

Our findings suggest that almost half of women with stage IIIC 2 can be cured with surgical staging and adjuvant therapies. The most common pattern of failure was distant metastasis calling for further optimization of systemic therapy.
