Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Other interventions - Local Therapy

Other: Local Therapy - The local therapy offered will be determined by the participant's doctor in consultation with the site multidisciplinary team and will be dependent on the size and location of the brain metastases.
Neurosurgery: The surgery may be performed up to 6 weeks before participant being registered on the trial or up to 4 weeks after registration.
Sometimes stereotactic radiosurgery is required to be delivered to the cavity left after the metastasis has been removed (Cavity Boost).
Stereotactic Radiosurgery: Treatment is to commence within 4 weeks of study registration. The size, number and location of the brain metastasis will determine the dose and fractionation schedule of radiotherapy.


Other interventions: Local Therapy
Neurosurgery: The decision whether or not to recommend neurosurgery will be made independently of this research study. The complexity and length of the surgery depends on the size and location of the tumour(s).
Stereotactic Radiosurgery: If the participant will be receiving stereotactic radiosurgery (either alone or in combination with neurosurgery), the Radiation Oncologist will organise for the participant to have a Radiotherapy planning. Single metastasis, smaller than or equal to 2cm, may require 1 fraction. Alternately, multiple metastasis, metastasis in the brain stem, or those bigger than 2cm will required multiple fractions to treat. The dose range for the study is 20Gy/1 fraction to 24Gy/3 fractions.

completion of brain metastasis treatment

- Able to undergo MRI scanning
Minimum age
18 Years

Summary
Brief summary
This study aims to show that brain metastases from Human Epidermal Growth Factor Receptor
Type 2 (HER2) positive breast cancers are able to be controlled by local therapies,
Stereotactic Radiosurgery (SRS) and/or Neurosurgery (NS), without the need for Whole Brain
Radiotherapy (WBRT).
