| Abstract |
Objective
GK Radiosurgery is minimally invasive, safe, and effective way to control local tumor progression and prolong survival.
Methods
We treated 40 metastatic brain tumor patients with Gamma-Knife radiosurgery from January 2011 to December 2015. 12 patients were enable to follow-up. Male to female ratio was 2:1, mean age was 79.4 years (75-90 years). Mean Karnofsky performance scale was 84.7 (70-90). Mean tumor volume was 11.6 cc (0.1-35.85 cc). Maximal dose range from 20-40 Gy (mean 26.5 Gy), marginal dose range from 10-18 Gy (mean 13.6 Gy).
Results
Primary tumors sites were all lung cancers. lesion site was 2 single lesions and 9 multiple lesions. Survival time was mean 9.3 months (2-29 months) Single metastatic brain tumor was much longer survival than multiple tumor. Most of them died of other problem than nervous system problem.
Conclusion
The local control of brain metastases has been shown to improve the quality and length of survival in elderly patients with systemic malignancies. |
