AIM: Although several studies have reported various causes of ischemic stroke in patients with cancer, only a few have evaluated the clinical relevance of ischemic stroke pathogenesis to cancer. The aim of the present study was to elucidate the clinical characteristics of cancer-associated ischemic stroke.
METHODS: We evaluated 154 ischemic stroke patients without cancer and 57 ischemic stroke patients with cancer who had either received continuous treatment for cancer within 5 years before to the onset of ischemic stroke, or who had been diagnosed with cancer within 1 year after the onset of ischemic stroke. Cancer patients were grouped into "cancer-associated ischemic stroke," the "conventional ischemic stroke," or "other."
RESULTS: A total of 15 patients (26%) were classified into the cancer-associated ischemic stroke in cancer patients. In univariate analysis of the cancer-associated ischemic stroke and the others, there were significant differences in the prevalence of hypertension, hyperlipidemia and advanced cancer (clinical stage IV), and the levels of d-dimer, fibrin degradation product and hemoglobin. With multivariate regression analysis of those factors, the prevalence of hypertension, hyperlipidemia and advanced cancer (clinical stage IV), and the levels of D-dimer and fibrin degradation product remained as statistically independent factors, which were associated with cancer-associated ischemic stroke (n = 111, χ(2) =67.21, P < 0.0001).
CONCLUSION: In acute ischemic stroke, the cancer-associated ischemic stroke is associated with elevated D-dimer and fibrin degradation products, even after controlling hypertension, hyperlipidemia and advanced cancer (clinical stage IV).
