Incidence of lymphoid neoplasms by subtype among six Asian ethnic groups in the United States, 1996-2004.
OBJECTIVE
To establish baseline data for lymphoid neoplasm incidence by subtype for six Asian-American ethnic groups.


METHODS
Incident rates were estimated by age and sex for six Asian ethnic groups--Asian Indian/Pakistani, Chinese, Filipino, Japanese, Korean, Vietnamese--in five United States cancer registry areas during 1996-2004. For comparison, rates for non-Hispanic Whites were also estimated.


RESULTS
During 1996-2004, Filipinos had the highest (24.0) and Koreans had the lowest incidence (12.7) of total lymphoid neoplasms. By subtype, Vietnamese and Filipinos had the highest incidence for diffuse large B-cell lymphoma (DLBCL) (8.0 and 7.2); Japanese had the highest incidence of follicular lymphoma (2.3). Although a general male predominance of lymphoid neoplasms was observed, this pattern varied by lymphoid neoplasm subtype. Whites generally had higher rates than all Asian ethnic groups for all lymphoid neoplasms and most lymphoma subtypes, although the magnitude of the difference varied by both ethnicity and lymphoma subtype.


CONCLUSIONS
The observed variations in incidence patterns among Asian ethnic groups in the United States suggest that it may be fruitful to pursue studies that compare Asian populations for postulated environmental and genetic risk factors.
