Brain metastases treated with CyberKnife and TomoTherapy: A report of three cases

This study aimed to compare the safety and efficacy of CyberKnife (CK) versus TomoTherapy for the treatment of brain metastases (BMs). Three cases of BM treated at our hospital – two with CK and one with TomoTherapy – were compared and analyzed. Both treatments showed good therapeutic effects, but CK was more effective. No radiation-related adverse reactions were observed in the three patients. It is concluded that both CK and TomoTherapy can effectively control target lesions by allowing a higher dose in a single treatment while minimizing damage to surrounding normal brain tissue. This can reduce the total number of treatments needed, improve the prognosis of patients, and save medical resources.
