Abstract

IntroductionThe influence of time to surgery on racial/ethnic disparities in papillary thyroid carcinoma (PTC) survival remains unstudied. Materials and methodsThe National Cancer Database (2004–2017) was queried for patients with localized PTC. Survival data was compared by time to surgery, patient demographics, and multivariable Cox regression was performed. ResultsOf 126,708 patients included, 5% were Black, 10% Hispanic. Of all patients, 85% had no comorbidities. Non-Hispanic White (NHW) patients had a shorter median time to surgery than Black and Hispanic patients (36 vs. 43 vs. 42 days, respectively p ​< ​0.001). In multivariable analysis, longer time to surgery (>90 days vs ​< ​30 days) and Black race vs NHW, were associated with worse survival (HR: 1.56, (95%CI, 1.43–1.70), p ​< ​0.001 and HR: 1.21, (1.08–1.36), p ​= ​0.001), respectively. ConclusionDelaying surgery for thyroid cancer is associated with worse survival. However, independent of time to surgery and other confounders, there remains a disparity as black patients have poorer outcomes.
