Background and Purpose- Recent guidelines have suggested the potential benefit of intravenous thrombolysis in stroke patients with systemic malignancy who have a reasonable life expectancy of >6 months. However, it is difficult to determine which patients with cancer will have a life expectancy of >6 months. Therefore, we identified the factors associated with 6-month mortality in patients with acute ischemic stroke and systemic malignancy. Methods- Consecutive stroke patients with systemic malignancy were retrospectively analyzed. We classified the patients into 3 groups: the nonactive cancer, active nonmetastatic cancer, and metastatic cancer groups. We compared the baseline characteristics and 6-month survival rates. Results- Of the 468 ischemic stroke patients with systemic malignancy during an 8-year period, 223 patients had nonactive cancer, 105 patients had active nonmetastatic cancer, and 140 patients had metastasis. During the 6-month follow-up, 122 patients (26.1%) died (nonactive cancer group [7.2%, 16/223], active nonmetastatic cancer group [11.4%, 12/105], and metastatic cancer group [67.1%, 94/140]). Multivariate Cox regression analysis revealed that the presence of metastasis (hazard ratio, 4.527; 95% CI, 2.175-9.422) was independently associated with 6-month mortality. However, the active nonmetastatic cancer group exhibited similar 6-month mortality to the nonactive cancer group (hazard ratio, 0.711; 95% CI, 0.282-1.795). Gastric/esophageal cancer and pancreatic cancer were also independently associated with 6-month mortality (hazard ratio, 2.068 and 2.389, respectively). Conclusions- In stroke patients with active cancer, the presence of metastasis and the cancer type were crucial factors associated with 6-month mortality.
