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

Abstract

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.

Spatio-Temporal Analysis of Cholangiocarcinoma in a High Prevalence Area of Northeastern Thailand: A 10-Year Large Scale Screening Program

“…These results are consistent with previous studies from Thailand, which have consistently shown that CCA incidence is higher in males than females, with the majority of cases occurring in individuals over 60 years old [ 31 , 27 , 20 ]. Furthermore, earlier studies conducted in Thailand in 2021 and 2023 also reported an association between higher rates of CCA and male gender and the age group over 60 years [ 32 , 16 ]. This association has been reported in various studies conducted in different years, emphasizing the importance of monitoring these specific risk factors in CCA incidence.…”

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

“…All tests were two-sided, with statistical significance set at a p-value less than 0.05. STATA version 18 (StataCorp, College Station, TX) was utilized for all analyses [ 19 ].…”
