Radiosurgery With or Without Whole Brain Radiation for Multiple Metastases

Inclusion Criteria

• •Histologic or cytologic diagnosis of non-hematopoietic malignancy (excluding germ cell malignancies and small cell carcinoma).
• •Patients with ≥ 5 but ≤ 30 de novo brain metastases seen on a diagnostic-quality contrast-enhanced MRI obtained within 30 days prior to enrollment (or randomization if previously randomized). Patients who are found to have 31-50 metastatic lesions at the time of treatment planning may still participate in the study. Disease progression such that \> 50 brain metastases are detected after initial MRI prior to enrollment but before SRS will be treated off-protocol as per discretion of the treating physician.
• •Patients with ≥ 5 but ≤ 30 new brain metastases who have undergone prior SRS for 4 or less brain metastases with stable intracranial disease as per diagnostic MRI for at least 6 months post last course of SRS. Patients who are found to have 31-50 new metastatic lesions at the time of treatment planning may still participate in the study. Disease progression such that \> 50 new brain metastases are detected after initial MRI prior to enrollment but before SRS will be treated off-protocol as per discretion of the treating physician.
• •Age ≥ 18.
• •Karnofsky Performance Status (KPS) ≥ 70.
• •Baseline HVLT-R above ≥ 6
• •Patients must be able to tolerate WBRT, and all brain lesions must be eligible for treatment with SRS as determined by the radiation oncologist.
• •Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.
• •Patient is able to read, speak, and understand (i.e. sufficiently fluent) English in order to allow completion and meaningful analyses of the neurocognitive tests and quality of life questionnaires.
• •Patients must be accessible for treatment and follow up. Investigators must assure themselves the patients registered on this trial will be available for complete documentation of the treatment, adverse events, and follow-up.
• •Patients who are on immunotherapy must have immunotherapy held at least 1 week before and after completion of radiotherapy. Other targeted agents/therapy must be held at least 1 day before and after SRS. Systemic chemotherapy must be held one week prior to treatment and re-started one week after treatment is complete.
• •Protocol treatment is to begin within 4 weeks of patient enrollment (or randomization if previously randomized).
