THE BASIS OF RACIAL DIFFERENCES IN THE INCIDENCE OF THYROID CANCER
The Basis of Racial Differences in the Incidence of Thyroid Cancer
BACKGROUND: The incidence of thyroid cancer in black Americans is half that in white Americans. It is unknown whether this gap represents a accumulation difference in disease or is imputable to inferior cancer display in the black population.
METHODS: A population-based people study of 53,990 patients (1973-2003) was performed using the National Cancer Institute’s Surveillance Epidemiology End Results database. Socioeconomic variables were explored using the Healthcare Cost and Utilization Project database and macroeconomic data.
RESULTS: Since 1973, thyroid cancer incidence among whites has increased 150.2% (4.0 to 9.9 of 100,000), while incidence among blacks has increased 73.2% (3.0 to 5.1 of 100,000). Across 17 regions, the incidence correlated with the proportionality of the accumulation with health insurance (r = 0.56, P = .02). Regression psychotherapy suggested that half of the black-white incidence gap might be imputable to differences in health insurance status. Patients with thyroid cancer were more likely to be insured or shack in wealthier ZIP codes. Negroid patients were more likely to inform at modern geezerhood (RR 1.08, P < .0001) and with tumors >4 cm in filler (RR 1.13, P <.0001). Negroid patients were slightly less likely to inform with modern disease (RR 0.96, P = .0008). Cancer-specific mortality was identical in the two populations.
DISCUSSION: Sociodemographic data and differences at show support a diminutive detection disparity in thyroid cancer, which may advance to conception of the incidence gap. However, this effect is not sufficiently strong to fully explain the incidence gap. A accumulation difference in the incidence of disease may be coexistent.
