My mum has adenocarcinoma with mets to brain treated with WBR in Dec 2012.
Since then she has had good quality of life and little permanent damage. Her brain mets have recently returned. There are multiple wide spread small lessions with small amount of oedema.
We are in the process of evaluation if gamma knife is possible. A second option discussed is repeat of WBR over 10 days with a lower dose than her first treatment. My question is: Is there any data on the satefy and effectiveness of repeat Whole brain radiation?
