The Thrombectomy Dilemma in Stroke Patients With Active Cancer: To Treat or Not to Treat?

Year: 2026

Type: article

Abstract: Endovascular thrombectomy for acute large-vessel occlusion in patients with active cancer remains a difficult clinical decision. Multiple cohort studies and meta-analyses indicate that, when standard imaging and clinical criteria are applied, reperfusion success is high and symptomatic intracranial hemorrhage is broadly comparable with non-cancer populations, arguing against categorical exclusion. At the same time, registries show lower 90-day functional independence and higher 90-day mortality in active-cancer cohorts-effects likely driven by malignancy-related systemic factors and pre-existing functional compromise rather than procedural harm. This narrative review synthesizes efficacy and safety signals, highlights decision-grade outcomes that are seldom reported-early neurological change, performance status around 90 days, and whether systemic anticancer therapy is started or resumed. It sets out a clinical-ethical-economic framework to support selection, consent, and aftercare, including a pragmatic pathway for under-resourced settings based on non-contrast computed tomography (CT) or single-phase CT angiography where advanced perfusion imaging or magnetic resonance imaging are unavailable. We outline an Asia-Pacific collaborative program designed to identify subgroups that may benefit from reperfusion and initiation of active cancer care.
