[Related factors of early post-operative prognosis of meningiomas: an analysis of 953 surgical cases].

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).

Conclusion: 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.
