Background:
Patients of minority race/ethnicity have lower survival after diagnosis with most types of cancer. Little data are available concerning changes in disparity over time. Here, we examine changes in survival by race/ethnicity of patients with common cancers in two recent time periods.
Patients And Methods:
We used modeled period analysis to determine relative survival (RS) for non-Hispanic white (nHw), African-American (AA), and Hispanic patients in the Surveillance, Epidemiology, and End Results database diagnosed with common solid and hematological malignancies.
Results:
Five-year RS improved overall and for nHw for each tumor examined, ranging from + 2% points (pancreatic cancer) to + 16.4% points [non-Hodgkin's lymphoma, (NHL)]. Greater improvement was observed for AA and Hispanics than nHw in breast and prostate cancer and NHL. Less improvement was observed for AA and Hispanics than for nHw for lung and pancreatic cancer. No statistically significant improvement was observed for AA and Hispanics with myeloma or acute leukemia. Survival disparities ranging from 0.5% points (myeloma) to 13.1% points (breast) between nHw and AA remained.
Conclusions:
Progress has been made in decreasing disparities in survival between nHw and minorities in breast cancer, prostate cancer, and NHL. Little progress has been made in reducing disparities for the other studied cancers.

Truncation in Survival Analysis
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are observed.
