Radiation therapy for postoperation gliomas

Objective: To evaluate the effect of radiotherapy on gliomas and the prognostic factor.Methods: Seventy-four patients with gliomas were treated by radiotherapy.Among them,39 cases were in low grade(Ⅰ+Ⅱ grade),31 cases in high grade(Ⅲ+Ⅳ grade) and 4 cases had the ependyma tumor.All the patients received radiotherapy in 3-4 weeks after operation.Thirty-one cases were performed total resection,38 cases bulk-resection and 5 cases partial resection.Among them,16 cases of high grade received chemotherapy after radiotherapy.Results: The patients under the age of 45,the total resection group and the patients of lower-ranking in pathology had a higher survival rate(1,3 and 5 years)(P<0.05 to P<0.01).Conclusions: Radiotherapy is effective for patients with gliomas.Age,pathological grading,operation mode are the important prognosis factors.
