Abstract

|
|
To evaluate the effect of radiation therapy and prognostic factors in metastatic brain tumor, we analyzed the 29 patients diagnosed as brain metastases and treated with radiation therapy, retrospectively. We evaluated the symptom palliation effect and mean survival time of patients treated with radiation therapy by means of prognostic factors such as initial performance status, primary site, extracranial metastasis, radiation dose etc. Conclusively, we confirmed the good symptomatic response rate but poor survival time of these patients. Also, this study revealed that prognostic factors of metastatic brain tumor treated with radiation therapy were initial preformance status, age and radiation dose but sex, use of steroid, primary site and extracranial metastasis were not. To increase the survival time of the patients with brain metastases, further study for adequate radiation dose/fractionation schedule, combination with chemotherapy and surgical resection, and stereotactic radiotherapy will be needed.
