In the supplementary surgical group, the GTR rate was 65%. CyberKnife radiosurgery consistently resulted in tumor shrinkage.. GTR is

For now, adjuvant and neoadjuvant SRS show evidence of utility in achieving better local control after surgical removal of BM in comparison with surgery alone, but no specific

In comparison with conventional treatment plans, the differences in the Paddick conformity index and gradient index did not exceed 2%..
