Résumé :

Background: Stroke is a frequent complication in patients with cancer, occurring in nearly 15% of patients with cancer. However, cerebrovascular disease as the first manifestation of cancer has rarely been reported. Methods: We retrospectively reviewed all 5106 patients admitted for ischemic stroke to our stroke department between 1991 to 2004, and identified a group of 24 patients (0.4%) who had an underlying malignancy. Results: The mean age of the 24 patients was 52 ± 4.1 years and 62.5% were women. Vascular risk factors were found in only 41% of patients. The principal mechanisms of stroke pathogenesis were nonbacterial thrombotic endocarditis (8/24), diffuse intravascular coagulation (6/24), and atherosclerosis (5/24). The most frequent neoplasms were lung and breast cancer. All patients but 4 were diagnosed with an underlying malignancy at the second ischemic event. Mean follow-up of surviving patients was 29 months (3-60). Nineteen patients died (79%), with a median survival of 58 days after cerebral infarction. Conclusions: A systemic cancer workup should be considered in patients in whom stroke origin is unclear or who have an early vascular recurrence. Stroke as the first manifestation of an underlying malignancy is mostly secondary to specific cancer-related causes. Outcome is poor and correlates with both severity of neurologic disability and the stage of tumor. © 2008 National Stroke Association.
