For primary CNS lymphoma, when do you refer for whole brain radiation therapy (WBRT)?  

My experience has been that patients can be neurologically devastated years out from WBRT. In Medical Oncology practice at my institution, we do not refer to Radiation Oncology for WBRT as consolidation treatment, and I was surprised to find this recommendation in NCCN guidelines.
