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.

Survival after Diagnosis of Cervical Cancer Patients at a Tertiary Referral Hospital in Northeast Thailand

BACKGROUND

Cervical cancer (CC) is the third most common cancer in women globally, including Thailand, where the incidence rate was 16.2 cases per 100,000 individuals in 2018. Survival rates for patients with this condition have not improved over recent years. This study evaluated the survival rate and median survival time after diagnosis among CC patients, and investigated factors associated with survival in Northeast Thailand.

METHODS

This study included CC patients admitted to the gynecological ward at Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand from 2010 to 2019. Survival rates and median survival time since the date of diagnosis and 95% confidence intervals (CIs) were calculated. Multiple cox regression was performed to investigate factors associated with survival which were quantified by adjusted hazard ratios (AHR) and their 95% CIs.

RESULTS

Of 2,027 CC patients, the overall mortality incidence rate was 12.44 per 100 person-years (95% CI: 11.7 - 13.22), median survival time was 4.82 years (95% CI: 3.92 - 5.72), and 10-year survival rate was 43.16% (95% CI: 40.71 - 45.59). The highest 10-year survival rate was 87.85% (95% CI: 82.23 - 91.78) found among those with stage I CC, followed by those who received surgical treatment, which was 81.22% (95% CI: 74.47 - 86.35). Factors that were associated with decreased survival included age ≥60 years (AHR = 1.25; 95% CI: 1.07 - 1.46), health insurance with the Universal Health Coverage Scheme (UCS) (AHR = 6.26; 95% CI: 5.13 - 7.64), malignant neoplasms histopathology (AHR = 1.36; 95% CI: 1.07 - 1.74), and treatment with supportive care (AHR = 7.48; 95% CI: 5.22 - 10.71).

CONCLUSION

Among patients diagnosed with CC, those with stage I had the highest 10-year survival rate. CC patients with older age, UCS, malignant neoplasms histopathology, and received supportive care showed the highest survival association.
