Management of brain metastases with stereotactic radiosurgery alone versus whole brain irradiation alone versus both

Management of brain metastases with stereotactic radiosurgery alone versus whole brain irradiation alone versus both
Radiation Oncology

IntroductionThis prospective randomized study aimed to evaluate the role of WBRT + SRS compared to SRS alone and to WBRT alone in improvement of overall survival, brain local control and neurologic manifestations.Patients and methods: The trial included 60 patients with 1 to 3 brain metastases treated at the Radiotherapy Department, National Cancer Institute. 21 patients received WBRT + SRS, 18 patients received SRS alone and 21 patients received WBRT alone. Results: Median local control was significantly better for WBRT + SRS compared to SRS alone &WBRT alone (10 vs 6 vs 5 months, respectively, P = 0.04). There was non significant survival benefit for WBRT + SRS compared to SRS alone & WBRT alone. Survival was significantly better for patients with controlled primary tumor who received WBRT + SRS compared to SRS alone & WBRT alone (median survival was 12 vs 5.5 vs 8 months, respectively. P = 0.027). Regardless of the treatment group, median survival and median local control were highly significantly better for single brain site involvement compared to multiple brain sites involvement (P = 0.003 & P = 0.001, respectively), and median brain local control was significantly better for single lesion compared to multiple lesions (P = 0.05). Conclusions: WBRT + SRS is an effective, safe tool in treatment of patients with 1 to 3 brain metastses improving the brain local control, but further studies with larger number of patients is recommended.
