Background: Cancer continues to be the leading cause of death in the Hispanic population. Gastrointestinal cancer surveillance data in Hispanic individuals has only recently become available in the last 3 decades. Differences in incidence rates among Hispanics and Non-Hispanic Whites (NHWs) need further elucidation. In this study, we analyzed trends in Hispanics and NHW populations across multiple gastrointestinal cancers. Methods: Gastrointestinal cancers (liver, colon and rectum, pancreas, esophagus, gallbladder, stomach, small intestine, anus, anal canal and anorectum) diagnosed between 2000-2019 were identified in the Surveillance, Epidemiology, and End Results Program (SEER) Database. We calculated incidence rates, confidence intervals and incidence rate ratios. Rates are per 100,000 and age adjusted to the 2000 US standard population. Rate ratios are the rounded rates in Hispanic individuals divided by the rounded rates in NHWs. Results: There was a higher incidence of liver, gallbladder, and stomach cancers among Hispanics when compared to NHWs between the years 2000-2019. Liver cancer incidence rate is (11.5 per 100,000) in Hispanics compared with (6.3 per 100, 000) in NHWs with an incidence rate ratio of 1.8. Gallbladder cancer incidence rate is (2.2 per 100,000) in Hispanics compared with (0.9 per 100,000) in NHWs with an incidence rate ratio of 2.4. Stomach cancer is (10.9 per 100,000) in Hispanics compared with (5.7 per 100,000) in NHWs with an incidence rate ratio of 1.9. The lowest incidence rate ratio was seen for anus, anal canal and anorectum cancers in Hispanics compared to NHWs. The incidence rate is (1.2 per 100,000) in Hispanics compared with (2.1 per 100,000) in NHWs with an incidence rate ratio of 0.6. Remaining cancers had incidence rate ratios less than 1.0 and were more likely to occur in NHWs. Conclusions: This study illustrates differing incidence rates of multiple gastrointestinal cancers among Hispanics compared to NHWs. Liver, gallbladder and stomach cancer incidence rates in Hispanics is double that of NHWs. Interestingly, the remaining gastrointestinal cancers had higher incidence rates among NHWs. Further research is warranted to understand the differences in cancer risk within the Hispanic population as well as healthcare access, language barriers and cultural differences that may play a role.
