摘要

PURPOSE The purpose of this study was to compare the clinical efficacy and safety of temozolomide (TMZ) combined with three-dimensional conformal radiotherapy (3D-CRT) and radiotherapy alone after surgery in patients with high-risk low-grade gliomas (LGGs). METHODS Patients (N=110) with LGGs were enrolled. Patients receiving TMZ chemotherapy combined with radiotherapy were considered as combination group (n=55), while those treated with radiotherapy alone were regarded as control group (n=55). The patients were followed up, and the overall survival (OS) and progression-free survival (PFS) were recorded. Finally, factors possibly affecting prognosis were analyzed. RESULTS The follow-up results exhibited median OS [(67.4±8.8) months vs. (63.9±8.6) months] and median PFS [(51.1±7.6) months vs. (46.8±6.9) months] as well as three-year OS rate and three-year PFS rate in combination group and control group. Log-rank test indicated that the difference in OS was not statistically significant between the two groups of patients, and PFS in combination group was significantly superior to that in control group. The results of univariate and multivariate analysis displayed that age <40 years old and complete tumor resection were independent factors affecting the three-year OS of patients with high-risk LGGs. Besides, age <40 years old, complete tumor resection and TMZ chemotherapy combined with radiotherapy after surgery were independent factors affecting the three-year PFS of patients with high-risk LGGs. CONCLUSION TMZ chemotherapy combined with radiotherapy after surgery in patients with high-risk LGGs can prominently improve clinical efficacy, prolong PFS, and facilitate tolerance to adverse reactions, but not prolong the OS of patients. The OS is notably prolonged in patients aged <40 years old and receiving complete tumor resection.
