Trends in pancreatic cancer incidence and mortality in the United States from 2000 to 2019; a SEER based study

Background:   The annual incidence and mortality rates of pancreatic cancer has been rising. We analyzed pancreatic cancer trends by demographics and geographic location. Methods: :  Data was obtained from the Surveillance, Epidemiology, and End Results (SEER) registry 17 were available to assess trends of pancreatic cancer incidence and mortality from 2000 to 2019. Results: :  The pancreatic cancer incidence and mortality rates consistently increased over time from 2000 to 2019. Incidence of pancreatic cancer was highest in males (14; 95% Cl, 13.9,14.1) and blacks (15.4 95% Cl,15.2, 15.6). The incidence was highest in Alaska (16.2; 95% Cl, 14.1, 18.5), and lowest in Utah (10.7; 95% Cl, 10.4, 11.0). Incidence increased at 0.85% per year (95% Cl, 0.76, 0.92; P < .001). Overall incidence increased significantly for all sex, race, stage sub-groups except for Blacks (APC of 0.04%; 95% Cl, -0.14, 0.22; P = 0.649), and American Indian/Alaska natives (APC of -0.22 %; 95% Cl, -1.33, 0.89; P= 0.679). There was an overall significant increase in incidence across all states except for Alaska. Incidence-based mortality of pancreatic cancer was highest in males (12.6; 95% Cl, 12.5,12.7) and blacks (14.1; 95% Cl, 13.9, 14.3). Mortality was highest in Alaska (15.1; 95% Cl, 13.1,17.3), and lowest in Utah (9.6; 95% Cl, 9.3,9.9). Mortality increased at 0.91% per year (95% Cl, 0.32, 1.50; P = .005). The overall incidence-based mortality increased significantly only in the males APC, 0.95% (95% Cl, 0.36, 1.54; P = 0.003), females APC 1.18 (95% Cl, 0.47, 1.89; P = 0.002) and whites APC 1.05% (95% Cl, 0.45, 1.66; P = 0.002). Furthermore, there was an overall significant increase in incidence-based mortality across all states except for Alaska, Hawaii and Washington. Conclusion: Pancreatic cancer incidence and mortality rates increased overall but differed by demographics and geographic location.
