One hundred ten patients with brain metastases (76 lung cancer, 11 breast cancer, 7 colorectal cancer and others) were treated with radiotherapy, and the results were retrospectively evaluated. Neurologic symptoms were improved in 66% of patients. The relationship between improvement of neurologic symptoms and several factors, including irradiation dose, primary lesion, histology, term between first treatment and recurrence, clinical symptoms and CT findings, was analyzed. There was no significant correlation between symptom relief and these factors except for the number of metastatic lesions. Four of 110 patients could survive more than 2 years after radiotherapy: one with lung cancer, one with breast cancer, one with rectum cancer and one with uterine cancer. The factors that were analyzed for symptom relief were also studied to determine their effect on the survival of lung cancer patients with brain metastases. The patients who had higher dose irradiation (50 Gy) of improvement of neurological symptoms after radiotherapy survived significantly longer than those who had 30 Gy of irradiation or no symptom relief. Multivariate analysis of these factors showed that improvement of symptoms and irradiation dose were similarly important prognostic factors, whereas the others were not correlated with survival.
