Abstract

PURPOSE/OBJECTIVE(S): The impact of competing medical comorbidity on survival endpoints in women with early stage endometrial carcinoma (EC) is not well studied. The study goal was to utilize a validated comorbidity scoring system to determine its impact on all-cause mortality as well as on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) in patients with early-stage EC.

MATERIALS AND METHODS: For this IRB-approved study, we reviewed our prospectively maintained uterine cancer database of 1720 patients. We identified 1132 patients with EC FIGO stages I-II who underwent hysterectomy from 1984 to 2011. Age-adjusted Charlson Comorbidity Index (AACCI) at time of hysterectomy was retrospectively calculated by physician chart review. The cause of death (uterine cancer-related and unrelated) was correlated with AACCI. Univariate and multivariate modeling with Cox regression analysis was used to determine significant predictors of OS, DSS, and RFS. The Kaplan-Meier and the log-rank test methods were used to evaluate survival outcomes.

RESULTS: After a median follow-up of 51 months, 262 deaths were recorded (42 from EC [16%], and 220 [84%] from other causes). Median AACCI score for the study cohort was 3 (range, 0 to 15). On the basis of AACCI, patients were grouped as follows: 0 to 2 (group 1, n=379), 3 to 4 (group 2, n=532), and ≥5 (group 3, n=221). By AACCI grouping, the 5-year RFS, DSS, and OS were 95%, 98%, and 97% for group 1, 89%, 95%, and 87% for group 2, and 86%, 95% and 72% for group 3 (P

CONCLUSIONS: The cause of death for women with early stage EC is mainly nonuterine cancer-related. Comorbidity score is a significant predictor of OS in our study cohort. Comorbidity scores may be useful as a stratification factor in any prospective clinical trial for women with early-stage EC.
