Comorbidities, Clinical Features, and Prognostic Implications of Cancer Patients with Cerebrovascular Disease.

PURPOSE:The objective of this study was to identify and describe the comorbidities, clinical features, and prognostic implications of cancer patients with cerebrovascular disease. MATERIALS AND METHODS:All patients with cerebrovascular disease (CVD) seen in the neuro-oncology unit at a cancer referral center from April 2010 to November 2016 were included; demographic, oncologic diagnosis, risk factors, and prognostic considerations were presented as well. RESULTS:We report on 256 patients with CVD and cancer, of whom 66% were women. The mean age at the time CVD occurred was 56 years. The most frequently associated malignancies were gynecologic (including breast cancer), hematologic, head and neck, and urologic. The men had more smoking and alcohol consumption history, hemorrhagic CVD, and urologic and hematologic malignancies. The women, besides gynecologic cancer, had more ischemic CVD. Thrombotic CVD, followed by embolic and hemorrhagic CVDs, was more frequent. A comorbid condition besides cancer was found in 71% of the patients. The most frequent clinical presentation was focal motor weakness, altered mental status, and aphasia. The 10-year mortality was 59%; higher rates were found in men, in those with hemorrhagic CVD, in tobacco users, and in those with altered mental status. CONCLUSIONS:Cancer is a well-known risk factor for stroke, which has been associated with a higher frequency in cancer. We found that ischemic stroke due to thrombosis and cardioembolism was more common, and gender, comorbidities, clinical presentation, and type of CVD, but not cancer type, were elements associated with prognosis.
