Clinical efficacy of early postoperative intensity-modulated radiotherapy combined with Temozolomide chemotherapy in the treatment of patients with malignant glioma
Abstract
Objectives: To evaluate the clinical efficacy of early postoperative intensity-modulated radiotherapy (IMRT) combined with temozolomide chemotherapy in the treatment of patients with malignant glioma.
Methods: In this retrospective cohort study 80 patients with glioma surgery admitted to Chengde Central Hospital from January 2019 to January 2021 were selected and divided into two groups according to postoperative treatment: the experimental group and the control group, with 40 cases in each group. Patients in the experimental group received IMRT combined with temozolomide chemotherapy postoperatively, while those in the control group received IMRT alone. The clinical effects of patients were analyzed before treatment and three months after treatment, and the incidence of adverse reactions such as bone marrow suppression, gastrointestinal reactions, fever, and liver dysfunction were analyzed in the two groups within one month after treatment. Before treatment and two months after treatment, MMSE scale, QOL scale and KPS were used to compare the cognitive function and health status of the patients. All patients were followed up for one year after treatment, and the difference of disease progression-free survival and overall survival rate between the two groups was analyzed.
Results: The effective rate of the experimental group was 70% after treatment, while that of the control group was 43.3%, with a statistically significant difference (P=0.04). The incidence of adverse reactions was 50% in the experimental group and 40% in the control group, with no statistically significant difference between the two groups (P=0.25). After treatment, MMSE score, QOL score and KPS score of the experimental group were significantly improved compared with those of the control group, with statistically significant differences between the two groups (MMSE score, QOL, P=0.00; KPS, P=0.01). Moreover, the two groups of patients were followed up for one year after treatment. The disease progression-free survival rate of the experimental group was 70% and that of the control group was 47.5%, with a statistically significant difference (P=0.04), and the overall survival rate of the experimental group was significantly higher than that of the control group after treatment, with a statistically significant difference (P=0.03).
Conclusion: Early postoperative IMRT combined with temozolomide chemotherapy is an effective treatment regimen for patients with malignant glioma, boasting a variety of advantages such as high efficiency, cognitive function, favorable recovery of health status, significantly improved progression-free survival rate and overall survival rate, and no significant increase in adverse reactions.
