INTRODUCTION: The incidence of cancer-associated ischaemic stroke (IS) is increasingly prevalent. This study aimed to assess the levels of enlarged perivascular spaces in basal ganglion (BG-EPVS) in cancer-associated patients who had a stroke compared with the control group, and to investigate the diagnostic utility of BG-EPVS in the context of cancer-associated stroke.
METHOD: A matched case-control study was conducted in Xiamen, China. A total of 184 IS patients (cancer vs control=1:1) were recruited. The severity of BG-EPVS was graded using high-resolution MRI. Patients' gender, age, clinical risk factors, other imaging changes and laboratory findings information at admission were collected. Logistic regression models were constructed and subgroup analysis by cancer treatment.
RESULT: Overall, 65.22% of the 184 subjects were male, with a mean (SD) age of 68.83±10.52 years. BG-EPVS had a significant influence on cancer-associated stroke (OR=1.85 (95% CI 1.29, 2.71), p=0.001) after adjusting for gender, age, clinical risk factors, other imaging changes and laboratory findings. The area under the curve of the diagnosis model that combined BG-EPVS and other factors was 0.848 (95% CI 0.787, 0.896), significantly higher than the other three models. Subgroup analysis suggested a heightened association between BG-EPVS and cancer-associated stroke within the cancer treatment group.
CONCLUSION: In conclusion, this is the first study to assess the diagnosis values of BG-EPVS on cancer-associated stroke and helps us understand the pathogenesis of cancer-associated stroke. Our findings demonstrate the effectiveness of BG-EPVS in diagnosing IS patients who may carry underlying cancer.
