Descriptive epidemiology of non-Hodgkin's lymphoma in Oklahoma: 1997-2003.
OBJECTIVE
To describe the incidence of Non-Hodgkin's lymphoma in Oklahoma residents.


METHODS
Case data were obtained from the Oklahoma Central Cancer Registry for Oklahomans diagnosed between 1997 and 2003. Age-adjusted incidence rates (AAIR) and standardized incidence ratios (SIR) were calculated for four racial and ethnic groups as well as four histological subtypes.


RESULTS
3,687 cases were diagnosed between 1997 and 2003, which was an average age-adjusted incidence rate of 14.9 cases per 100,000 Oklahomans. A 23% increase occurred in the AAIR between 1997 and 2003. A non-significantly elevated SIR was found among American Indians (AI) when compared to Whites: 1.12 (0.78-1.18). African Americans had a significantly lower SIR when compared to Whites: 0.72 (0.44-0.79). AI males were found to have increasing incidence throughout their lifetime, with the highest rate occurring in the oldest age group. This differs from the other racial/ethnic groups analyzed whose rates decreased in this age group.


CONCLUSIONS
Further research is warranted to identify factors that may increase risk of development of NHL for American Indians in Oklahoma.
