Objective: To explore the correlation of various influencing factors with the extent of peritumoral brain glioma edema.
Methods: A total of 69 glioma cases were confirmed by pathology after operation. And stepwise multiple linear regression analysis was performed on gender, age, Karnofsky performance scale (KPS) score, onset to treatment time, tumor size, location, shape and WHO pathological grade.
Results: All of them had peritumoral edema. The relevant factors included pathology grading, onset to treatment time, KPS score and age. The data were entered into the regression equation of edema index. The partial regression coefficients were 0.853, 0.456, -0.352 and 0.291 respectively (P < 0.01).
Conclusion: Peritumoral brain edema in glioma patients are correlated with WHO pathologic grading, onset to treatment time, KPS score and age. But it has no correlation with patient gender, tumor location, tumor size and shape.
