Evaluating the Prognostic Factors and Survival Rates of Endometrial Cancer Patients in a Tertiary Referral Hospital in Northeast Thailand

OBJECTIVES: This study aims to determine the 5-year and 10-year overall survival rates, mortality incidence, median survival time, and factors influencing the survival of endometrial cancer (EC) patients’ post-diagnosis at the largest hospital in northeast Thailand.

We particularly focus on the impact of access to health insurance schemes.

METHODS: We conducted a retrospective analysis of data from EC patients admitted to Srinagarind Hospital between 2010 and 2019.

Overall survival was estimated using the Kaplan-Meier method.

Multivariate Cox regression analysis identified factors associated with survival, with results expressed as adjusted hazard ratios (AHR) and 95% confidence intervals (CI).

RESULTS: Among the 673 patients, the 5-year overall survival rate stood at 76.43% (95% CI: 72.72-79.70), and the 10-year rate at 67.86% (95% CI: 62.98-72.25).

Notably, advanced age (≥60 years), stage III and IV cancer, and non-endometrioid histopathology were found to significantly increase post-diagnosis mortality risk (AHR = 2.39, 3.13, 4.62; 95% CI: 1.03-5.53, 2.07-4.74, 2.66-8.04; p-value <0.05, <0.001, <0.001).

Surprisingly, we observed no significant correlation between health insurance schemes and mortality risk, suggesting that different insurance programs did not significantly affect EC patient survival in this study.

CONCLUSION: health insurance schemes had no significant impact on endometrial cancer patient outcomes in Thailand, likely due to comprehensive coverage.

Treatment modalities, notably surgery, showed no statistically significant differences, possibly due to early diagnosis.

High-risk groups may benefit from adjuvant therapy.

Early surgical intervention is crucial, with its association with disease stage emphasized.

These findings inform cancer care decisions and healthcare policy development.
