Ischemic Stroke Risk Among Adult Brain Tumor Survivors: Evidence to Guide Practice.
Karl Cristie F Figuracion, Wonkyung Jung, Sarah R Martha
PMID 34320512WHAT IT FOUND
Brain tumor survivors have a seven-fold increased risk of acute ischemic stroke, and nurses are advised to use survivorship visits to screen for risk, teach BE-FAST, and coordinate lifestyle and imaging surveillance.
These are review recommendations, not tested outcomes.
Key findings
01The review reports a seven-fold increased risk of acute ischemic stroke among brain tumor survivors.
02Cranial radiation is linked to later ischemic stroke: a dose greater than 54 cGy to the posterior fossa and Circle of Willis region increased risk by 9%, and each additional 100 cGy increased risk by 5%.
03In active cancer-related ischemic stroke, low-molecular-weight heparin and aspirin showed no difference in recurrent thromboembolism or mortality, and no published evidence evaluates antithrombotics in brain tumor patients with ischemic stroke.

What it does not show
This is a narrative review, not a trial or cohort study, so it summarizes existing literature and practice recommendations rather than testing a nursing or rehabilitation intervention. The exact prevalence of acute ischemic stroke in adult brain tumor survivors is unknown. The search was limited to CINAHL and PubMed, English language, 2000 to 2021, adults, and human studies, so relevant evidence outside those limits was not considered. Several treatment statements are based on limited evidence: there are no clinical trial data for endovascular therapy in brain tumor survivors with stroke, and no published evidence evaluates antithrombotics in brain tumor patients with stroke. The review recommends imaging screening and nurse education, but it does not report outcomes after these recommendations are implemented.
The easy way to misread this
Do not read the seven-fold stroke risk, radiation dose figures, or BE-FAST advice as proof that nurse-led screening or education prevents stroke. The paper is a review of limited literature and expert recommendations; it does not test the recommended actions or show improved patient outcomes.
