Clinical presentations and outcomes in pulmonary embolism patients with cancer

AbstractTo study whether a diagnosis of cancer affects the clinical presentation and outcomes of patients with pulmonary embolism (PE). A retrospective analysis was performed of all consecutive patients diagnosed with PE on a computed tomography scan from 2014 to 2016 at an urban tertiary-referral medical center. Baseline characteristics, treatment decisions, and mortality data were compared between study subjects with and without a known diagnosis of active cancer. There were 581 subjects, of which 187 (33.0%) had a diagnosis of cancer. On average, cancer subjects tended to be older (64.8 vs. 58.5  years, p <  0.01), had lower body mass index (BMI) (29.0 vs. 31.5 kg/m2, p  = 0.01), and were less likely to be active smokers (9.2% vs. 21.1%, p <  0.01), as compared to non-cancer subjects. Cancer subjects were also less likely to present with chest pain (18.2% vs. 37.4%, p <  0.01), syncope (2.7% vs. 6.6%, p = 0.05), bilateral PEs (50% vs. 60%, p = 0.025), and evidence of right heart strain (48% vs. 58%, p = 0.024). There was no difference in-hospital length of stay (8.9 vs. 9.4 days, p = 0.61) or rate of intensive care unit (ICU) admission (31.9% vs. 33.3%, p = 0.75) between the two groups. Presence of cancer increased the risk of all-cause one-year mortality (adjusted HR 9.7, 95% CI 4.8–19.7, p <  0.01); however, it did not independently affect in-hospital mortality (adjusted HR 2.9, 95% CI 0.86–9.87, p = 0.086). ...
