Correlation analysis of preoperative images and surgical outcomes in patients with meningiomas / 中华神经医学杂志

ABSTRACT

Objective To investigate the role of preoperative image information in tumor resection degrees,surgical complications and mortality of patients with meningiomas.Methods One hundred and seventy-two patients with meningiomas,admitted to our hospital from January 2008 to June 2011,were chosen in our study; the complete image informations,including tumor location,tumor size,nerves and vessels wraping around tumor or tumor wraping around nerves and vessels,tumor invasiveness,tumor margin,tumor shape,degrees of tumor enhancement and peritumoral brain edema,were retrospectively analyzed; univariate factor Chi-square test was performed to analyze the factors influencing the extent of tumor resection,surgical complications and death.Binary logistic stepwise regression analysis was performed to analyze statistical significance of the factors.Results Tumor location,tumor size,tumor invasiveness,tumor shape and tumor margin were the five independent risk factors of tumor residual,and tumor invasiveness was the primary risk factor.Tumor location,tumor size,nerves and vessels wraping around tumor or tumor wraping around nerves and vessels,and degrees of tumor enhancement were the four independent risk factors of surgical complications,and tumor location was the primary risk factor.Tumor location and tumor size were two independent risk factors of morbidity,and tumor location was the primary risk factor of mortality.Conclusion Preoperative image information of meningioma,especially the four primary factors (tumor location,tumor size,tumor invasiveness,and nerves and vessels wraping around tumor or tumor wraping around nerves and vessels),may objectively and accurately to estimate and evaluate meningioma resection degree,surgicalcomplications and mortality.
