Abstract:
Objective To evaluate prognostic factors of patients with cerebral postoperative glioma treated with three-dimensional conformal radiotherapy (3DCRT). Methods62 patients with cerebral glioma who had residual tumor received 3DCRT. Factors such as gender, age, location of the glioma, pathological type, pathological grade, degree of surgical resection, combined chemotherapy, radiation dose, Karnofsky score before treatment were analyzed to show wether the impact on prognosis, Drawing survival curve with the Kaplan-Meier method, Log-rank test for univariate analysis and multivariate analysis were performed by using COX regression model.ResultsLast follow-up time was April 1, 2009. Median follow-up was 22 months, 43patients died. The 1-, 2- and 3-year overall survival rate were 65.7 %, 34.2 % and 20.5 %. In univariate analysis, the survival was related to age (P=0.008), pathological grade (P=0.016), degree of surgical resection (P=0.000), Karnofsky score before treatment (P =0.018). In COX multivariate modal, age (P =0.031), degree of surgical resection (P =0.000), Kamofsky score before treatment (P =0.035) were independent prognostic factors. ConclusionAge ＜40 years, Karnofsky score before treatment ≥70 and mostly resection are independent factors for predicting better survival of glioma patients.
