Abstract

BACKGROUND: Thrombolytic therapy significantly improves outcomes among patients with acute ischemic stroke. While cancer outcomes have dramatically improved, the utilization, safety, and mortality outcomes of patients with cancer who receive thrombolytic therapy for acute ischemic stroke are unknown.

METHODS: Using a national database, we identified all hospitalizations for acute ischemic stroke requiring thrombolytic therapy between 2003 and 2015. Patients with contraindications to thrombolytic therapy were excluded. Following propensity score matching for comorbidity burden, trends in thrombolytic therapy use and its effect on in-hospital mortality, intracranial or all-cause bleeding, and the combined endpoint of mortality and all-cause bleeding, by presence/absence of cancer were evaluated. We also evaluated 30- and 90-day readmission rates post-thrombolytic therapy administration.

RESULTS: We identified 237,687 acute ischemic stroke hospitalizations requiring thrombolytic therapy, of which 26,328 (11%) had an underlying cancer. Over the study period, thrombolytic therapy use increased across all acute ischemic stroke admissions, irrespective of cancer presence (12.4/1000 in 2003 to 81.1/1000 in 2015,

CONCLUSIONS: Contemporary thrombolytic therapy use for acute ischemic stroke has risen, irrespective of presence of cancer. Yet, patients with comorbid cancer appear to see lower rates of thrombolytic therapy use for acute ischemic stroke, despite no difference in the rate of intracranial bleeding or mortality after adjustment for comorbidities.
