Introduction: Aortic body tumors are rare intrathoracic tumors. The majority of existing literature for aortic body tumors exists as case reports or a limited series. Our aim was to analyze a large national database, providing a contemporary view of this cancer. Methods: The national cancer database, which includes data from 1,500 cancer centers was queried to retrospectively review all aortic body tumors between 2004 and 2015. The cohort was divided into patients who underwent surgery versus those who were treated with chemotherapy or radiation. Cohorts were assigned a year range based on when they were diagnosed. Survival between these cohorts were compared using Kaplan-Meier survival estimates. Cox multivariable analysis was performed using baseline variables (age, year range, metastasis, surgery, radiation, and chemotherapy). Overall survival of the cohort was analyzed via Kaplan-Meier survival estimates. Results: A total of 87 patients who were diagnosed with an aortic body tumor were identified. The mean age was 51 ± 15.7 years and the majority of patients were female (51.7%). Most patients were treated at an academic/research center (62.7%) or a comprehensive community cancer program (25.4%). A significant portion of patients (19.5%) had metastatic disease on diagnosis. The treatment modalities utilized were surgery (54%), radiation (44.8%), and chemotherapy (20.7%). Long-term survival was 35.5% with a median survival of 8.25 years (Figure 1A) . Overall survival was significantly higher in the surgery cohort (p<0.001) (Figure 1B) . On Cox multivariable analysis (Figure 1C) , surgery (HR 0.32, p=0.01) was associated with increased survival. An independent predictor of mortality was having a metastasis on diagnosis (HR 8.49, p=0.001). Conclusion: The overall prognosis of aortic body tumors is poor, with metastasis on presentation significantly increasing mortality. Surgery provides a substantial benefit to these patients; however, this may be a result of selection bias. Aggressive surveillance in predisposed populations may be warranted given the grave prognosis once metastasis occurs.
