SYSTEMIC THROMBOLYSIS IN PATIENTS WITH ACUTE STROKE AND ACTIVE CANCER: A SYSTEMATIC REVIEW AND META-ANALYSIS
Abstract
Background and Aims
Cancer patients frequently have concomitant cerebrovascular diseases, which significantly worsen their prognosis. Prospective studies validating intravenous thrombolysis (IVT) safety profile in patients with acute ischemic stroke and active cancer are still lacking. Our aim was to evaluate efficacy and safety profile of IVT in acute ischemic stroke patients with comorbid active cancer.
Methods
We included in a meta-analysis all relevant published studies including patients with acute ischaemic stroke with or without active cancer, and receiving IVT, according to recommendations for IVT treatment for acute ischaemic stroke. The primary outcomes were all-cause mortality, any intracerebral haemorrhage and functional outcome, reported as modified Rankin Scale (mRS).
Results
Nine studies were included in the meta-analysis. IVT was not associated with a significant increase in the incidence of intracerebral haemorrhage (OR 1.00; 95%CI 0.76 – 1.33; I2 48.07%), nor with a significant increase in death for any cause (OR 1.13; 95%CI 0.90 – 1.43; I2 51.6%); furthermore, IVT did not influence mRS between cancer and non-cancer stroke patients (OR 1.00; 95%CI 0.58 – 1.71; I2 27.42%).
Conclusions
IVT seems to be safe and effective on patients affected by an ischemic stroke and concomitant cancer. Due to the low overall quality of the evidence, high-quality randomized control trials with adequate sample sizes are needed.
