Estimates of Survival and Incidence of Cervical Cancer in Loei Province, Thailand, For 2017-2022: Preliminary Results

Background: Cervical cancer (CC) is a leading cause of cancer-related death among women worldwide, yet regional incidence and survival trends in Thailand are under-documented. This study aimed to estimate the incidence and survival rates of CC in Loei Province, Thailand. Methodology: This retrospective cohort study analyzed data from 228 CC patients diagnosed between 2017-2022, from the Loei Population-Based Cancer Registry. Survival rates were estimated using the Kaplan-Meier method, while age-standardized incidence rates (ASR) and trends were evaluated using Joinpoint Regression. Results: The 5-year overall survival rate for CC was 51.1%. The overall age-standardized incidence rate (ASR) was 10.0 per 100,000 person-years. A statistically non-significant decreasing trend was observed during the study period Annual Percent Change (APC) = -0.97%. Conclusions: The 5-year overall survival for cervical cancer was 51.1%. The decreasing age-standardized incidence rate (ASR) suggests the positive impact of long-standing public health interventions, such as HPV vaccination and screening policies. Continued monitoring of incidence trends and strengthening cancer registry coverage are crucial for enhancing future cancer control programs in Thailand.
