Usually the treatment of a single brain metastasis is surgery or Stereotactic Radiosurgery (SRS). Surgery involves resection of the brain tumor by means of an operation, whereas SRS is treatment consisting of highly focused radiation doses to the tumor. These two treatment modalities are both widely used, well established, and proven to improve survival, but so far, no study has been done to directly compare the efficacy of one over the other. Neither treatment in itself is considered to be experimental and both have been shown to provide benefits to patients with metastatic brain tumors. The aim of this study is to determine which two modalities are better for local control and improving quality of life.

Patients who consent to this study will be randomized to either receive surgery or Radiosurgery in the treatment of single brain metastases. The study seeks to recruit 12 patient to each group. Patients will be in this study for up to five years from the time of the treatment finished. This will include follow-up visits at 4 weeks after the procedure and then every 3 months after the procedure up to 5 years.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Feasibility of a Prospective, Randomized Trial Comparing Surgery Versus Radiosurgery for the Treatment of Single Brain Metastases

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:
  • To determine the feasibility of accrual to a randomized trial of SRS vs Surgery in patients with single brain metastasis. [ Time Frame: 2 years ]
  • To compare the incidence of recommendation for a second local therapeutic intervention to the treated metastasis at 1 year. [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • To compare overall survival between the two randomized cohorts. [ Time Frame: 2 years ]
  • To compare local-recurrence-free survival between the two randomized cohorts. [ Time Frame: 2 years ]
  • To compare CTCAE v 3.0 neurological outcomes [ Time Frame: 2 years ]
  • To evaluate difference in neurocognitive outcomes [ Time Frame: 2 years ]
  • To measure and compare quality of life [ Time Frame: 2 years ]
  • To determine adverse effects attributable to local therapy [ Time Frame: 2 years ]
  • To compare medication requirements in each cohorts (steroids, anticonvulsants) [ Time Frame: 2 years ]
  • To explore potential predictive factors of outcomes [ Time Frame: 2 years ]
  • To investigate potential biofluid and imaging biomarkers of response [ Time Frame: 2 years ]
  • To compare ECOG performance status [ Time Frame: 2 years ]

Arms Assigned Interventions
Active Comparator: Radiosurgery (SRS) Procedure: Stereotactic Radiosurgery
This will be delivered using Gamma Knife technology. Patients randomized to this arm will be fitted with a stereotactic head-frame for stereotactic localization of brain metastases.
Active Comparator: Surgery Procedure: Surgery
Prior to surgery, patients will have placement of scalp fiducials and undergo a contrast enhanced MRI scan. Once the patient is anesthetized or sedated, the head will be secured with a head frame and scalp fiducials will be registered to the stereotactic neuronavigation system. The tumor will then be resected and the patient will be taken to the recovery unit.


Ages Eligible for Study:   19 Years and older   (Adult, Senior)

  6. Patients must have normal organ and marrow function
  7. Women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
