A clinical research on the potential pathogenesis of somatic cancer related cerebral venous sinus thrombosis

Abstract

To investigate the pathogenesis of somatic solid cancer-related cerebral venous sinus thrombosis (CVST). A total of 174 patients with CVST were recruited from the hospital between January 2006 and December 2017 and divided into two groups: (1) somatic cancer-related CVST group, defined as active somatic solid cancer patients with acute CVST; (2) cancer group (CG), defined as active somatic solid cancer patients without CVST. The cancer group patients were age and gender-matched somatic cancer-related CVST group patients. In addition, the types and amount distribution of cancer in cancer group were also matched with somatic cancer-related CVST group patients. Compared to cancer group patients, somatic cancer-related CVST group patients had more intracranial metastasis, a higher platelet count, higher plasma D-dimer, carcinoembryonic antigen (CEA) and cancer antigen (CA) 125 levels, a greater platelet to lymphocyte ratio (PLR), and a greater platelet to neutrophil ratio (PNR). The risk for CVST in somatic cancer-related CVST group patients increased independently by 0.7% (odds ratio [OR] 1.007; 95% confidence interval [CI] 1.000, 1.015; P=.047) with a 1ng/ml increase in D-dimer levels, by 4.6% (OR 1.046; 95% CI 1.011, 1.083; P=.010) with a 1U/ml increase in CEA, by 2.7% (OR 1.027; 95% CI 1.003, 1.051; P=.025) with a 1U/ml increase in CA125, and by 10.6% (OR 1.106; 95% CI 1.002, 1.220; P=.045) with a 1 unit increase in PNR. It was suggested that together impacts of elevated plasma D-dimer, CA125, CEA levels, and a greater PNR may lead to hypercoagulability and to trigger the development of cancer-related CVST.
