While immunotherapy (IT) has improved outcomes in other solid tumors, its role in ATC remains unclear. This study evaluated whether receipt of IT was associated with improved overall survival (OS) in the initial treatment of patients with newly diagnosed ATC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We performed a retrospective study of patients with metastatic and nonmetastatic ATC from the National Cancer Database (2008\u20132020) treated with surgery, radiation, chemotherapy, or a combination. Patient outcomes were stratified between those who received IT at any point in their treatment compared with those who did not. The primary outcome was OS, compared between cohorts receiving IT and those who did not. Survival analyses were performed using Kaplan\u2013Meier estimates, long-rank tests, and multivariable models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Among 3318 patients with ATC, 87 (2.6%) received IT.

Median OS was 9.1 months (confidence interval [CI] 7.06\u201314.9) for those receiving IT versus 3.78 months (CI: 3.52\u20134.01) for those who did not (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.005).
