Epidemiology of the Incidence and Mortality of Pancreas Cancer and its Relationship with the Human Development Index (HDI) in the World: An Ecological Study in 2018
Objective: Pancreatic cancer is one of the leading causes of mortality in developed countries and a lethal malignant neoplasm worldwide. This study aims to evaluate the epidemiology of pancreatic cancer incidence and mortality and its relationship with HDI. Methods: This is a descriptive cross-sectional study that is based on cancer incidence data and cancer mortality rates derived from the GLOBOCAN in 2018. : The incidence and mortality rates of Pancreas as well as Pancreas cancer distribution maps were derived for world countries. The data analysis was conducted using a correlation test, and regression tests were used to evaluate the correlation of the incidence and mortality of Pancreas with HDI. The statistical analysis was carried out by Stata-14, and a significance level of 0.05 was considered. Results: The highest incidence of pancreatic cancer was reported in Asia with 214499 (46.7%) cases and the lowest incidence was related to Oceania with 4529 cases (0.99%). The results showed a positive and significant correlation between incidence (r = 0.764, P <0.0001) and mortality (r = 0.771, P <0.0001) of pancreatic cancer and the HDI index. The results of ANOVA revealed that the highest mean incidence was related to the very high HDI (P <0.0001) and the highest mortality was connected to the very high human development (P <0.0001). The results exhibited that incidence was positively and significantly correlated with GNI (r = 0.497, P <0.0001), MYS (r = 0.746, P <0.0001), LEB (r = 0.676, <0.0001) and EYS (r = 0.738, P <0.0001). Also, a significant positive correlation was found between mortality and GNI (r = 0.507, P <0.0001), MYS (r = 0.745, P <0.0001), LEB (r = 0.679, <0.0001), and EYS (r = 0.748, P <0.0001). Conclusion: Given the higher incidence and mortality of pancreatic cancer in countries with HDI, it is necessary to pay a greater attention to risk factors and appropriate planning to reduce these factors and minimize the impact and mortality rate of this disease.
