Background and Objective: Incidence of Liver cancer (LC) in Nakhon Phanom province tends to increase. The spatial factor is an important factor. The purpose of this study was to analyze spatial factors and incidences rate of LC in Nakhon Phanom province.
Methods: A retrospective descriptive study was used for this study. Of 1,899 LC patients lived in Nakhon Phanom province and treated in Nakhon Phanom hospital between January 1, 2010 to December 31, 2019 were obtained from the Hospital-database. The studied factors were personnel profile, climatic and environmental factors. The Moran's I and Anselin Local Moran's I, LISA determined relationship. The Age-Standardized Rate, ASR were reported with their 95% confidence interval.
Result: The ASR of LC was 22.5 per 100,000 population year (95%CI: 21.5 to 23.5). Morans I analysis was spatially correlated with variables. The statistical significance of the clustered pattern were the distance from the water resources, population density, and altitude variables (p < 0.05). The LISA, 99 sub-districts with LC incidence according to the following variables; 4 sub-districts as for attitude, 22 sub-districts as for distance from the water resources and in14 sub-districts as for population density.
Conclusion: LC is a high incidence rate in the sub-district area and adjacent area in Muang district. It is also found as the clustered of LC. Further research should focus on the relationship between exposure and LC in this area have affected the incidences in Thailand might shed some new light on the prevention and control of LC.
