ABSTRACT
BACKGROUND:
The patterns and mechanisms underlying stroke in cancer patients differ from those of the conventional etiology. In this study, we further investigated the characteristics distinguishing cancer-associated ischemic stroke (CAIS) and the relationship of D-dimer value with CAIS.METHODS:
Sixty-one acute ischemic stroke patients with cancer (cancer group) and 76 stroke patients without cancer (control group) were recruited. Cerebrovascular distribution was divided into 3 circulations and 23 vascular territories, and acute multiple brain infarcts (AMBIs) were defined as discrete MRI diffusion-weighted imaging (DWI) lesions in >1 vascular territory.RESULTS:
Cancer patients had higher average D-dimer and fibrinogen degradation product values, and fewer stroke risk factors. The numbers of infarct-affected vascular territories, AMBIs, and AMBIs in multiple circulations were significantly higher in the cancer group. Receiver operating characteristic analysis showed that the cutoff value of D-dimer was 2.785 µg/ml; and above features were particularly evident in cancer patients whose D-dimer values were >2.785 µg/ml, while those with D-dimer values ≤2.785 µg/ml were similar to controls.CONCLUSIONS:
D-dimer >2.785 µg/ml may be an effective cutoff value and a sensitive index for identifying CAIS patients. AMBIs in ≥3 vascular territories and AMBIs in both the anterior and posterior circulations are two imaging characteristics of CAIS.Palavras-chave
