Abstract
Background
Disparities have been previously described in the presentation, management, and outcomes of other thyroid cancer subtypes; however, it is unclear whether such disparities exist in anaplastic thyroid cancer (ATC).
Methods
We identified patients with ATC from the National Cancer Database (2004–2020). The primary outcomes were receipt of surgery, chemotherapy, and radiation. The secondary outcome was 1-year survival. Multivariable logistic and Cox proportional hazards regressions were used to assess the associations between sex, race/ethnicity, and the outcomes.
Results
Among 5359 patients included, 58% were female, and 80% were non-Hispanic white. Median tumor size was larger in males than females (6.5 vs. 6.0 cm; p < 0.001) and in patients with minority race/ethnicity than in white patients (6.5 vs. 6.0 cm; p < 0.001). After controlling for tumor size and metastatic disease, female patients were more likely to undergo surgical resection (odds ratio [OR]: 1.20; p = 0.016) but less likely to undergo chemotherapy (OR: 0.72; p < 0.001) and radiation (OR: 0.76; p < 0.001) compared with males. Additionally, patients from minority racial/ethnic backgrounds were less likely to undergo chemotherapy (OR: 0.69; p < 0.001) and radiation (OR: 0.71; p < 0.001) than white patients. Overall, unadjusted, 1-year survival was 23%, with differences in treatment receipt accounting for small but significant differences in survival between groups.
Conclusions
There are disparities in the presentation and treatment of ATC by sex and race/ethnicity that likely reflect differences in access to care as well as patient and provider preferences. While survival is similarly poor across groups, the changing landscape of treatments for ATC warrants efforts to address the potential for exacerbation of disparities.
