Core Tip

Core Tip: Using province-level multi-center hospital surveillance data from 262 hospitals in Gansu Province, China from 2013 to 2023, we quantified pancreatic cancer incidence trends and mapped county-level spatiotemporal clusters. It was found that age-standarded incidence increased from 2.39 per 100000 people to 3.23 per 100000 population, with consistently higher rates in men and older adults. Spatial autocorrelation and SaTScan revealed persistent high-risk hotspots concentrated in the Hexi region, and an increasing burden in the Dwb climate zone. These results provide an evidence for targeted prevention, earlier diagnosis, and resource allocation in high-risk counties.
