Introduction We aim to investigate the difference in mechanical thrombectomy (MT) outcome for cancer‐related stroke (CRS) with active and inactive cancer. Methods Of the consecutive acute ischemic stroke (AIS) patients admitted to our institute from 2010 to 2021, patients with cancer who received MT within 24 hours of onset and were enrolled.Outcomes including the favorable outcome (modified Rankin Scale score of 0 to 2) at3 months, 1‐year,and death within 3 months or 1‐yearwere assessed between patients with active and inactive cancer among patients with cancer. The rate offirst pass effect (FPE, extendedThrombolysis in Cerebral Infarction[eTICI] 2c/3 after first pass) and final eTICI 2c/3 achievement were also assessed. Active cancer was defined as a cancer that was diagnosed within 6 months; required chemotherapy or surgical treatment within 6 months; or was recurrent, metastatic, or inoperable. Results Of 59 patients (26 women; median age, 80 years; median NIH Stroke Scale score[NIHSS] 17), 19 (32.2%) patients had an active cancer. Patients with active cancer has less atrial fibrillation (47% vs. 78%,P< 0.01) and higher medianD‐dimer(4.60μg/mLvs. 2.00μg/mL,P< 0.01). There were no significant differences in the favorable outcome at 3 months (26% vs. 45%,P = 0.26) and at 1 year (26% vs. 45%,P = 0.26) between both groups, but death within 3 months (32% vs. 5%,P< 0.01) and within 1 year (42% vs. 8%,P< 0.01) were more frequent in patients with active cancer than those with inactive cancer. Conclusions Long‐term clinical outcomes of patients with active cancer were worse than those with inactive cancer.
