A new report suggests African Americans (AAs) have significantly lower rates of most hematologic malignancies than non-Hispanic white (NHW) individuals in the US.

AAs of both sexes had significantly lower rates of leukemia, Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL) than NHWs, but the rate of myeloma was significantly higher among AAs.

The death rates for these malignancies followed the same patterns, with the exception of HL. There was no significant difference in HL mortality between AAs and NHWs of either sex.

These findings can be found in the report, “Cancer Statistics for African Americans, 2016,” appearing in CA: A Cancer Journal for Clinicians.

To compile this report, the researchers used data from the Surveillance, Epidemiology, and End Results program and the Centers for Disease Control and Prevention’s National Program of Cancer Registries.

Incidence

For part of the report, the researchers compared the incidence of cancers between AAs and NHWs (divided by gender) for the period from 2008 to 2012.

Among females, the incidence of leukemia was 8.6 per 100,000 in AAs and 10.7 per 100,000 in NHWs (P<0.05). Among males, the incidence was 13.2 per 100,000 in AAs and 17.7 per 100,000 in NHWs (P<0.05).

The incidence of HL in females was 2.4 per 100,000 in AAs and 2.7 per 100,000 in NHWs (P<0.05). The incidence of HL in males was 3.2 per 100,000 in AAs and 3.4 per 100,000 in NHWs (P<0.05).

The incidence of NHL in females was 12.0 per 100,000 in AAs and 16.6 per 100,000 in NHWs (P<0.05). The incidence of NHL in males was 17.2 per 100,000 in AAs and 24.1 per 100,000 in NHWs (P<0.05).

The incidence of myeloma in females was 11.1 per 100,000 in AAs and 4.3 per 100,000 in NHWs (P<0.05). The incidence of myeloma in males was 14.8 per 100,000 in AAs and 7.0 per 100,000 in NHWs (P<0.05).

Mortality

The researchers also compared cancer mortality between AAs and NHWs (divided by gender) for the period from 2008 to 2012.

The death rate for female leukemia patients was 4.8 per 100,000 in AAs and 5.4 per 100,000 in NHWs (P<0.05). The death rate for male leukemia patients was 8.1 per 100,000 in AAs and 9.9 per 100,000 in NHWs (P<0.05).

The death rate for female HL patients was 0.3 per 100,000 for both AAs and NHWs. The death rate for male HL patients was 0.4 per 100,000 for AAs and 0.5 per 100,000 in NHWs (not significant).

The death rate for female NHL patients was 3.6 per 100,000 in AAs and 5.0 per 100,000 in NHWs (P<0.05). The death rate for male NHL patients was 5.9 per 100,000 in AAs and 8.3 per 100,000 in NHWs (P<0.05).

The death rate for female myeloma patients was 5.4 per 100,000 in AAs and 2.4 per 100,000 in NHWs (P<0.05). The death rate for male myeloma patients was 7.8 per 100,000 in AAs and 4.0 per 100,000 in NHWs (P<0.05).

The researchers noted that the reasons for the higher rates of myeloma and myeloma death among AAs are, at present, unknown.
