This applies to the treatment of cerebral metastases as well. The present study focused on elderly patients receiving stereotactic radiosurgery (SRS) for few cerebral lesions. Patients and Methods: In 95 patients aged ≥65 years, two SRS doses, 16-18 Gy (n=44) and 20 Gy (n=51), were compared regarding outcomes of SRS. Results: The overall intracerebral control rates at 12 months were 30% after 16-18 Gy and 45% after 20 Gy (p=0.53). Twelve-month rates of freedom from new intracerebral lesions were 41% and 52%, respectively (p=0.63). Twelve-month local control rates of the irradiated lesions were 55% and 81%, respectively (p=0.069). Overall survival rates at 12 months were 29% and 31%, respectively (p=0.67). Conclusion: SRS with 16-18 Gy was not significantly inferior to SRS with 20 Gy in elderly patients with few cerebral metastases. ER -
