Risk of bias
Low risk of bias | Comments: Large RTOG RCT.Central randomisation. Good FU. ITT analysis. |
Size of effect
1 | Reason for decision: RCT of WBRT (37.5/15) +/- SRS boost for patients with 1-3 mets. No differences in mean survival, TTP or neurological death rates. Patients with SRS had improved PS and reduced steroid use at 6m. Patients with solitary met had improved mean survival with SRS (6.5vs4.9m) |
Relevance of evidence
1 | Additional comments: Endpoints of survival, also response, local control, performance status. |
