    • Abstract:
      Objective: To examine potential ethnic disparities in cancer incidence and survival rates among the oldest old using data from the SEER Program. Design: Cases diagnosed with one of the leading four cancer sites (lung and bronchus, colon and rectum, female breast, prostate) and four cancer sites (stomach, liver and intrahepatic bile duct, gallbladder, and cervical) that disproportionally affect Hispanics were reported to one of 18 SEER registries. Differences in cancer incidence were examined for cases aged ≥85 years diagnosed during the most recent 5-year time period (2009–2013) and, to examine changes over time, from 1992 to 2013. Five-year relative cancer survival probability was examined for Hispanics and non-Hispanics aged ≥85 years diagnosed 2006–2012. Results: From 2009 to 2013, non-Hispanics aged ≥85 years had higher incidence rates compared to Hispanics for colon and rectum, lung and bronchus, female breast, and prostate cancers. Five-year survival probability for cancers of all stages combined was higher for non-Hispanics than Hispanics in this age group. However, Hispanics had higher survival probability of colon and rectum and lung and bronchus cancers diagnosed at regional (colon and rectum: 67.2% vs. 60.5%; lung and bronchus: 15.9% vs. 12.7%) and distant (colon and rectum: 5.4% vs. 3.8%; lung and bronchus: 2.8% vs. 2.2%) stages than non-Hispanics, respectively. Conclusion: Ethnic differences in cancer incidence and survival probability exist for the ≥85 population. Continued efforts are needed to understand and reduce ethnic disparities in cancer prevention and treatment for this population. [ABSTRACT FROM AUTHOR]
