Abstract

Objective:

To evaluate the impact of race on survival in patients with papillary thyroid microcarcinoma.

Methods:

The study cohort included 17 668 patients diagnosed with papillary thyroid microcarcinoma between 1988 and 2009, identified in the Surveillance, Epidemiology, and End Results 18 database of the National Cancer Institute.

Results:

Black patients had lower overall survival than other racial groups (p < 0.001). Black patients had significantly worse overall survival (hazard ratio = 2.59) after adjusting for sex, marital status, age, year of diagnosis, multifocal disease and type of surgery. A subset analysis of Black patients revealed no significant difference in overall survival for total thyroidectomy versus lobectomy (p = 0.15).

Conclusion:

Black race is a negative prognostic factor in thyroid cancer, which cannot be explained by advanced disease stage. Further research on mechanisms by which race affects survival is needed to reveal areas of opportunity for interventions aimed at reducing health disparities in cancer care.
