Clinical practice: intravenous thrombolysis in a patient with active cancer who experienced wake-up stroke.

After reviewing the diagnosis and treatment process of a patient with active cancer who experienced wake-up stroke, we have summarized the clinical manifestations, laboratory examination results, imaging features, pathological results, and treatment in this report. Patients with active cancer who experience wake-up stroke often have mild neurological deficits at the time of onset. For the patient in this study, laboratory test results were mainly characterized by abnormal coagulation function and elevated tumor markers. The brain magnetic resonance imaging (MRI) images were characterized by involvement of both the arterial and venous systems. Thrombolytic therapy during the window period can improve the symptoms of neurological deficits. Overall, anticoagulation therapy was safe and effective in our patient.

Tumor metastasis has a significant relationship with the development of acute ischemic stroke in Chinese cancer patients: a retrospective study.

OBJECTIVE: This study was designed to analyze the relationship between tumor metastasis and acute ischemic stroke (AIS) in Chinese cancer patients. METHODS: This retrospective study included 119 cancer patients with AIS and 152 cancer patients without AIS. Basic information was collected and tumor metastasis status was determined for all patients. RESULTS: The whole cohort had a median age of 59 (49-69) years with 150 men (55.4%). There were 98 patients (36.2%) with tumor metastasis. Patients with AIS had significantly more males, tumor metastasis, lung cancer, hypertension, diabetes mellitus, higher age, D-dimer, international normalized ratio, prothrombin time, prothrombin activity, and thrombin time, while they had significantly lower levels of hemoglobin, red blood cells, and hematocrit. In multivariate logistic regression analysis, AIS was significantly and positively associated with age, tumor metastasis, D-dimer, and thrombin time. In multivariate Cox regression analysis, tumor metastasis, AIS, D-dimer, thrombin time, and fibrinogen were significantly and positively associated with worse prognosis. CONCLUSIONS: This study demonstrates that tumor metastasis was positively and independently associated with AIS in Chinese cancer patients, suggesting that tumor metastasis has a significant relationship with the development of AIS. Additionally, tumor metastasis and AIS had negative independent effects on the prognosis of patients.
