Long-Term Survival in Patients With Synchronous, Solitary Brain Metastasis From Non-Small-Cell Lung Cancer Treated With Radiosurgery

This is one of the largest series of patients diagnosed with synchronous, solitary brain metastasis from NSCLC treated with GKSRS. Definitive thoracic therapy and KPS significantly impacted OS. The 5-year OS of 21% demonstrates the potential for long-term survival in patients treated with GKSRS; therefore, patients with good KPS should be considered for definitive thoracic therapy.
