My daughter has diffuse b cell lymphoma stage 4b, treatment with r chop disease progressed, treatment with r GDP, treatment progressed to cns, treatment with high dose methotrexate has reduced cns cancer but systemic cancer is now growing again. She is 29 years old and will be starting chap next week for 2 cycles and then ?final restaging to determine if strictly palliative care is the only option. What end stage symptoms should we expect?
