title: [Related factors of early post-operative prognosis of meningiomas: an analysis of 953 surgical cases].
abstract: OBJECTIVE
  To study the related factors of early post-operative prognosis of meningiomas.
  
  
  METHODS
  The clinical data of 953 patients with meningiomas were recorded and statistically analyzed with χ(2) test of single factor and logistic regression model of multivariate factors. Patient age; tumor size; tumor location; pre-operative complication of patients such as hypertension, diabetes, heart disease and cerebral infarction; the extent of tumor resection; hemorrhagic shock; blood loss or hemorrhagic shock and brain swelling intra-operatively were taken as variables. The prognosis was evaluated by postoperative Karnofsky performance scale.
  
  
  RESULTS
  The prognosis was significantly correlated with the patient age, tumor size, tumor location, preoperative cerebral infarction, the extent of tumor resection, blood loss and hemorrhagic shock intra-operatively (P < 0.05). Such factors as tumor size, preoperative cerebral infarction, the extent of tumor resection (Simpson's scale) and intra-operative hemorrhagic shock were independent risk factors of prognosis for meningiomas. Other factors, such as hypertension, diabetes and heart disease, were unrelated with the prognosis of meningiomas (P > 0.05).
  
  
  CONCLUSIONS
  Patient age, tumor location and pre-operative complications of patients maybe affect the early postoperative prognosis of meningiomas. But such factors as tumor size, preoperative cerebral infarction, the extent of tumor resection and intra-operative hemorrhagic shock are independent risk factors for the post-operative prognosis of meningiomas.
