Summary

Brain metastases occur in 20% to 40% of all patients with cancer , with an incidence 10 times higher than that of primary malignant brain tumors. Patients with brain metastases have a poor prognosis with a median survival of 1-2 months with corticosteroids and 5-7 months with whole brain radiotherapy (WBRT). Local control achieved with WBRT in patients with otherwise controlled systemic disease remains at issue. A single high dose of radiation delivered with high precision to the target lesion (Stereotactic radiosurgery (SRS)), is considered standard care in salvage of recurrent lesions after WBRT. SRS can destroy tumour with very little damage to surrounding tissue. Research suggests that delivering radiotherapy in a number of smaller doses is more beneficial than receiving all of the radiotherapy in a single dose. Brain metastases are well suited for SRS as they are often small, radiographically well-circumscribed, pseudospherical tumors that are noninfiltrative.

RADIATION

Hypofractionated stereotactic radiotherapy

Patients will be initially administered 8 Gy RT (level). The dose at each level will be increase by 2 Gy up to level 4. If ≥ 2 of the patients in a dose cohort encounter a DLT, then that dose level will be declared the maximum administered dose. An additional 3 patients will then be entered at the previous dose level and provided no more than one patient experiences a DLT, that level will be declared the maximum tolerated dose (MTD). Up to 6 more patients can be treated at the given dose level while awaiting the results of 6 months of follow-up.
