Outcomes of patients with in-hospital stroke with and without active cancer.

BACKGROUND

Cancer is common in patients with ischemic stroke. The aim was to reveal the differences in acute management and outcomes of patients with in-hospital acute ischemic stroke (IHS) with and without active cancer.

METHODS

Two hundred IHS patients (58% male, median age 78 years, median NIHSS score 9) from August 2016 to July 2023 at our institution were divided into two groups: 70 with active cancer (IHS-AC 35%) and 130 without AC (IHS-nonAC 65%). Patients' characteristics, time intervals, and clinical outcomes were compared between the groups. A good clinical outcome was defined as modified Rankin Scale score 0-3.

RESULTS

IHS was identified most frequently by a nurse (IHS-AC group 67%, IHS-nonAC group 71%). Time from recognition to stroke physician assessment (37 vs. 90 min, p = 0.008) was shorter in the IHS-AC group. Good clinical outcomes at discharge (31% in each group, p = 1.000) and in-hospital mortality (IHS-AC group 29%, IHS-nonAC group 21%, p = 0.225) were similar in the groups. The rates of reperfusion therapy (intravenous rt-PA and/or mechanical thrombectomy) were 16% in the IHS-AC group and 15% in the IHS-nonAC group (p = 1.000). The rates of good clinical outcomes and mortality at discharge in patients with reperfusion therapy were each 36%.

DISCUSSION AND CONCLUSION

One-third of IHS patients had comorbid active cancer. The rates of reperfusion therapy and good clinical outcomes were similar in groups with and without active cancer. Acute stroke management should not be withheld solely based on cancer.
