Abstract
Background
Clinicopathologic variables influence the treatment and prognosis of patients with
thyroid cancer.
Methods
A retrospective analysis of public hospital thyroid cancer database and the Surveillance,
Epidemiology and End Results 17 database was conducted. Demographic, clinical, and
pathologic data were compared across ethnic groups.
Results
Within the public hospital database, Hispanics versus non-Hispanic whites were younger
and had more lymph node involvement (34% vs 17%, P < .001). Median tumor size was not statistically different across ethnic groups.
Similar findings were demonstrated within the Surveillance, Epidemiology and End Results
database. African Americans aged <45 years had the largest tumors but were least likely
to have lymph node involvement. Asians had the most stage IV disease despite having
no differences in tumor size, lymph node involvement, and capsular invasion.
Conclusions
There is considerable variability in the clinical presentation of thyroid cancer across
ethnic groups. Such disparities persist within an equal-access health care system.
These findings suggest that factors beyond socioeconomics may contribute to such differences.
