â¢The prognosis of brain metastases is poor and unsatisfactory.â¢KPS, number of brain metastases, extracranial metastases, treatment pattern were independent prognostic factors.â¢Good status preoperative and multimodality therapy improve patient's survival significantly.
BackgroudBrain metastases are the most common malignant intracranial tumors, however, the prognosis of patients is still poor despite multiple treatment have been applicated. The aim of this study was to analyse parameters influence overall survival from patient, tumor and treatment. Summarized characteristics of long-time (>2 years) survivors furtherly.Materials and methodsIn total, clinical data of 125patients between 2004 and 2015 were collected and the parameters from patients, tumor and treatment were evaluated. Univariate analysis was performed using Kaplan-Meier and Log-rank test, multivariate analysis was performed using Cox proportional hazards regression model, respectively.ResultsMedian overall survival time was 14.5 (95% confidence interval were 12.3-16.7) months and median survival time was 34.5 (95% confidence interval were 30.1-38.9) months in long-time survivors, respectively.KPS, RPA, GPA, number of brain metastases, extracranial metastases, treatment pattern and resection method were identified influence survival time significantly by univariate analysis. KPS, number of brain metastases, extracranial metastases and treatment pattern were independent prognosis factors by multivariate analysis. Long-time survivors obtain higher KPS, complete resection, adjuvant therapy postoperative more commonly.ConclusionHigher KPS, GPA I,RPA3.5â¼4, single brain metastases, adjuvant therapy postoperative and complete resection were significant improve survival time, however, extracranial metastases significant decreased survival time. Patients who have good status and received multimodality therapy involved complete resection can survive longer time more commonly.
