Critètes d'éligibilité
  • Patients must have 5 or more brain metastases as counted on a T1 contrast enhanced MRI obtained ≤ 30 days from randomization (maximum 15 brain metastases).
  • Patients must have a pathological diagnosis (cytological or histological) of a non-hematopoietic malignancy.
  • The largest brain metastasis must measure <2.5 cm in maximal diameter.
  • Centre must have the ability to treat patients with either a Gamma Knife, Cyberknife, or a linear accelerator-based radiosurgery system.
  • Patient must be > 18 years of age.
  • Patient is able (i.e. sufficiently fluent) and willing to complete the quality of life questionnaires in either English or French either alone or with assistance.
  • ECOG performance status 0, 1, or 2.
  • Creatinine clearance must be ≥ 30 ml/min within 28 days prior to registration.
  • The Neurocognitive Testing examiner must have credentialing confirming completion of the neurocognitive testing training.
  • Facility is credentialed by IROC to perform SRS. The treating centre must have completed stereotactic radiosurgery credentialing of the specific system(s) to be used in study patients.
  • Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrolment in the trial to document their willingness to participate.
  • A similar process must be followed for sites outside of Canada as per their respective cooperative group's procedures.
  • Patients must be accessible for treatment and follow-up. Investigators must assure themselves the patients randomized on this trial will be available for complete documentation of the treatment, adverse events, and follow-up.
  • In accordance with CCTG policy, protocol treatment is to begin within 14 days of patient enrolment.
  • Women/men of childbearing potential must have agreed to use a highly effective contraceptive method.
Critètes d'exclusion
  • Pregnant or nursing women.
  • Men or women of childbearing potential who are unwilling to employ adequate contraception.
  • Inability to complete a brain MRI.
  • Known allergy to gadolinium.
  • Prior cranial radiation therapy.
  • Planned cytotoxic chemotherapy within 48 hours prior or after the SRS or WBRT.
  • Primary germ cell tumour, small cell carcinoma, or lymphoma.
  • Widespread definitive leptomeningeal metastasis. This includes cranial nerve palsy, leptomeningeal carcinomatosis, ependymal involvement, cranial nerve involvement on imaging, suspicious linear meningeal enhancement, or cerebrospinal fluid (CSF) positive for tumour cells.
  • A brain metastasis that is located ≤ 5 mm of the optic chiasm or either optic nerve.
  • Surgical resection of a brain metastasis (stereotactic biopsies will be allowed).
  • More than 15 brain metastases on a volumetric T1 contrast MRI (voxels of 1mm or smaller) performed within the past 14 days, or more than 10 metastases in the case of a non-volumetric MRI.
  • Prior allergic reaction to memantine.
  • Current alcohol or drug abuse.
  • Current use of NMDA antagonists, such as amantadine, ketamine, or dextromethorphan.
  • Diagnosis of chronic liver disease/cirrhosis of the liver (e.g. Child-Pugh class B or C).
