The changes of plasma coagulation function in patients with glioma and its correlation with malignant grade of glioma

Abstract

Objective: To investigate the changes of activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time(TT), fibrinogen(FIB) and platelet counts(PLT) in plasma of patients with glioma, and to explore the correlations between PT, APTT, TT, FIB and PLT with malignant grades of glioma. Methods: One hundred and seventy-two patients with glioma and 47 health controls were investigated in a retrospective analysis. All patients were diagnosed and identified the WHO grade by pathologist after operation. Including 40 cases with glioblastoma multiforme, WHO Ⅳ grade, 45 cases with anaplastic astrocytoma, WHO Ⅲ grade, 46 cases with astrocytoma and oligodendroglia astrocytoma, WHO Ⅱ grade, and 41 cases with pilocytic astrocytoma. Results: PT was significantly shorter in patients with WHO Ⅰ-Ⅳ grade glioma than that in normal controls (P<0.05); APTT was significantly shorter in patients with WHO Ⅲ and Ⅳ grade glioma than that in normal controls and WHO Ⅰ grade glioma patients (P<0.05); FIB of WHO Ⅳ grade glioma was higher than that in normal control and WHO Ⅰ to Ⅲ grade glioma (P<0.05). While, there was no significant difference of TT and PLT among patients with WHO Ⅰ to Ⅳ and normal controls (P>0.05). Spearman correlation analysis showed that there was negative correlation between APTT and WHO grade (r=-0.200, P=0.007) as well as positive correlation between FIB and WHO grade (r=0.175, P=0.020); Pearson linear correlation analysis showed that there was negative correlation between APTT and Ki67 in patients with glioma. Conclusions: the levels of FIB and APTT in patients with glioma were correlated with WHO grade of glioma, and higher FIB, shorter APTT and PT in patients with WHO Ⅳ grade glioma indicated that there exist hypercoagulation states.
