Following radiotherapy and aggressive chemotherapy to treat Stage 4 Lung Cancer (non-small cell lung cancer metastesised to bones), my wife had extremely successful immunotherapy on a clinical trial leaving her with only 3 tiny lung tumours, which continue to shrink. Having effectively returned to normal and very active health for around 6 months, she experienced a dragging of one foot and within 10 days she was so dizzy that she could no longer walk without aid and she had double vision, making movement very uncomfortable. Her oncologist thinks she has suffered Paraneoplastic Cerebellar Degeneration and cerebellar damage has been identified in a recent MRI head scan. She now uses a zimmer frame to move (very slowly) around the house and a wheelchair for doctor/hospital visits. We had a 1-week holday to Cornwall in September, where we hired a mobility scooter and she successfully drove herself around the Eden Project and the Lost Gardens of Heligan. Since returning home, her condition seems to have worsened as she often needs close support when using her frame. Does anyone know of any treatments likely to arrest progression, to ease symptoms or to improve her quality of life? Our doctors don't seem to have much hope to offer.
