Descriptive epidemiology of non-Hodgkin's lymphoma in Oklahoma: 1997-2003
1Oklahoma State Department of Health, Chronic Disease Service, rm/205, 1000 NE 10th St., Oklahoma City, OK 73117, USA.
Objective:
To describe the incidence of Non-Hodgkin's lymphoma in Oklahoma residents.
Methodology:
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.
