Gynecologic and obstetric investigation
OBJECTIVES: We sought to evaluate the impact of age-adjusted Charlson comorbidity index (AACCI) score on survival endpoints for women with advanced stage endometrial carcinoma (EC).
METHODS AND MATERIALS: We identified 238 women with stage III EC. AACCI score was calculated and 3 groups were created accordingly; group 1 with a score of 0-2, group 2 with score 3-4, and group 3 with score ≥5. Significant predictors of recurrence-free (RFS), disease-specific (DSS) and overall survival (OS) were analyzed.
RESULTS: Median follow-up was 54 months and median age was 65 years. Stage IIIC was the most common stage (69%). The 3 groups were well-balanced except for less utilization of adjuvant chemotherapy in group 3 (p = 0.01). Five-year OS was significantly lower in group 3 compared to groups 1 and 2 (23 vs. 65 and 51%, respectively). Similarly, 5-year RFS was 54, 41, and 33% and DSS was 65, 54, and 35% for groups 1, 2, and 3 respectively. On multivariate analyses, AACCI group 3, cervical stromal involvement, positive peritoneal cytology, and higher tumor grade were predictors for shorter OS. Cervical stromal involvement and higher grade were independent predictors for worse RFS and DSS. Additionally, positive cytology, lymphovascular space invasion, and stage IIIC2 were significantly detrimental for RFS.
CONCLUSIONS: Our study suggests that comorbidity burden is a strong predictor of worse OS in women with stage III EC. Women with higher AACCI are less likely to receive adjuvant chemotherapy. Comorbidity score can significantly impact survival endpoints for women with advanced EC.
