Abstract
This study aimed to explore the geographic distribution and risk clusters of pancreatic cancer mortality from 2011 to 2013 in Shandong, China, and to detect the differences between urban and rural areas. Our data were obtained from the Shandong Death Registration System (SDRS) and were adjusted according to the underreporting level. The distribution of mortality was displayed with GIS-based maps at the county level. The results showed an increasing trend in pancreatic cancer mortality from the western region to the eastern region of Shandong. Additionally, four significant risk clusters were detected, and the most likely cluster was focused in the northeastern and northern regions. Urban-rural differences in the mortality distribution and risk clusters were also detected. In conclusion, our study identified pancreatic cancer mortality clusters in Shandong in urban and rural areas; these results can contribute to the development of effective and targeted strategies to control pancreatic cancer in different areas.
Highlights
Pancreatic cancer is one of the most fatal malignancies with approximately 338,000 new cases and 330,000 deaths per year
From 2011 to 2013, a total of 11468 pancreatic cancer deaths occurred in Shandong, with an average reported mortality rate (ARMR) of 4.00 per 100,000 people
Consistent with previous studies[24,25], our results showed that the mortality rate of pancreatic cancer displayed an increasing trend from the western region to the eastern region
Summary
Pancreatic cancer is one of the most fatal malignancies with approximately 338,000 new cases and 330,000 deaths per year. Some studies have shown that pancreatic cancer mortality in urban areas of China is higher than that in rural areas[3,10,11]. It is well evidenced that there are distinct differences in the geographic distribution of pancreatic cancer, and the mortality rates in urban areas and in the eastern region may be higher than those in rural areas and central and in the western region[10,11,12]. Using the same research method and statistical analysis, our study was conducted to examine the geographic distribution and risk clusters of pancreatic cancer mortality in Shandong, and to detect the differences between urban and rural areas
