The Synergy Factor: Trauma and Cancer

Trauma and cancer are the leading causes of death in the US. There is a paucity of data describing the impact of cancer on trauma patients. We aimed to determine the influence of cancer on outcomes of trauma patients. In this retrospective analysis of American College of Surgeons-Trauma Quality Improvement Program 2019-2021, we included all adult trauma patients (≥18 y) and excluded patients with severe head injuries and nonmelanomatous skin cancers. Patients were stratified into cancer (C), and no cancer (No-C). Propensity score matching (1:3) was performed. Outcomes were complications and mortality. A matched cohort of 3236 patients (C, 809; No-C, 2427) was analyzed. The mean age was 70 y, 50.5% were males, and the median injury severity score was 8 (4-10). There were no differences in terms of receiving thromboprophylaxis (C 51%: No-C 50%, P = 0.516). Compared to No-C group, the C group had higher rates of deep vein thrombosis (C 1.1% versus No-C 0.3%, P = 0.004), but there was no difference in terms of overall complications. Patients in the C group had higher mortality (C 7.5% versus No-C 2.7%, P
