Abstrakt: Background: This study assessed the difference in 3-, 5-, and 10-year relative survival rates (RSRs) for female breast cancer between White and Black patients across the levels of year, tumor stage, age, and marital status at diagnosis. Confounding factors and effect modifiers were considered.
Methods: Analyses were based on 17 population-based tumor registries in the Surveillance, Epidemiology, and End Results (SEER) Program. Cases were diagnosed in 2000-2017 and followed through 2020.
Results: Three-, 5-, and 10-year female breast cancer RSRs significantly improved for White and Black patients during the years 2000-2020, more so for Blacks than Whites. Three-, 5-, and 10-year estimated annual percent changes in trends were 0.09%, 0.16%, and 0.29% for Whites and 0.36%, 0.49%, and 0.86% for Blacks, respectively. However, a large difference in RSRs for White and Black patients persists, 4.2% for three-year RSRs, 5.7% for five-year RSRs, and 7.5% for 10-year RSRs, after adjusting for year, tumor stage, age, and marital status at diagnosis. The difference in RSRs between White and Black patients differs by tumor stage at diagnosis. For example, higher five-year RSRs in Whites than Blacks were 2.6% for local, 9.3% for regional, 10.4% for distant, and 6.2% for unknown/unstaged tumors at diagnosis.
Conclusion: Improvement in 3-, 5-, and 10-year female breast cancer RSRs occurred for both White and Black patients, albeit more so for Blacks. Yet the poorer RSRs for Blacks remain large and significant, increasingly so with later staged disease at diagnosis and as we move from 3- to 5- to 10-year RSRs.
