Acute Ischemic Stroke in People with Active Cancer
Official title: Clinical Characteristics and Stroke Recurrence in Patients With Acute Ischemic Stroke and Active Cancer: The CAT-AIS Multicenter Prospective Observational Study
Run by Osaka University · NCT07819526 · Data updated 2026-11-12
This study looks at how often people with active cancer have another ischemic stroke after an initial event, to see what factors might be linked to a recurrence.

Is this trial a fit for you?
✓Likely a good fit
Adults with acute ischemic stroke and active cancer at the time of the stroke who receive standard care at participating centers.
✕Probably not a fit
Patients whose stroke does not recur or whose outcomes are not influenced by cancer status may see no direct benefit.

What this trial studies
This is a multicenter prospective observational study conducted at 24 hospitals in Japan. It follows patients who have active cancer and recently experienced an acute ischemic stroke to observe how often another stroke happens within three months and what clinical factors may be associated with such recurrences. Data collected include cancer details, stroke characteristics, tests, treatments, and other outcomes, without assigning any specific treatment. The goal is to understand recurrence rates and related factors to inform future care decisions. No experimental interventions are performed; care remains at the discretion of the treating physicians.
Why it matters
Potential benefit: If successful, the study could clarify risk factors for recurrent stroke in cancer patients and help tailor follow-up and management to reduce future events.
How similar studies have gone: Previous observational work in cancer-associated stroke has shown variability in recurrence risk, making this study's prospective, multicenter design valuable for broader insight.
