Stereotactic Radiosurgery vs Whole Brain Radiotherapy in Breast Cancer With Brain Oligometastasis- A Randomised Controlled Phase 3 Trial
This trial aims to assess the impact of SRS on overall survival, PFS, radiation toxicity and quality of life as compared to WBRT in oligometastatic brain disease in breast cancer patients. Total 98 patients with breast cancer with brain oligo-metastases will be included. The WBRT dosage schedule will be 30 Gy in 10 fractions over 2 weeks. For tumors with 2cm, SRS dose of 22 to 25 Gy will be delivered and tumor larger than 2 cm will be treated with doses of 18 to 20 Gy.

• Histologically confirmed malignancy with metastatic disease detected on imaging.
• ECOG performance status 0-1
• 1 to 3 brain metastases, each with a maximum diameter of no more than 3 cm on contrast enhanced magnetic resonance imaging(MRI) scans
