The Glioblastoma Campaign was established by Baroness Margaret McDonagh and her sister Dame Siobhain McDonagh, the Member of Parliament for Mitcham and Morden. When Margaret was diagnosed with glioblastoma, they did the research and were appalled with what they learnt. They discovered that the treatment available on the NHS was woefully inadequate. All the money was being directed elsewhere. Doctors were being trained in other cancers with glioblastoma left by the wayside. Clinical trials were non-existent. The usual surgery and radiotherapy were available, but chemotherapy was being carried out with a drug stuck in a time warp. Margaret was too unwell to withstand the chemotherapy but, with private care from Dr Paul Mulholland, she was put on a regime of immunotherapies and hyperthermic treatments. The machine for the hyperthermic treatment was in Germany. Sometimes Margaret could barely get on the plane. Margaret and Siobhain launched a campaign and raised the funds to support glioblastoma research. Dr Mulholland now has a hyperthermic machine to use in the UK. Margaret died in June 2023, but the campaign continues. Dame Siobhain is excited by the Win-Glio trial programme, established in Margaret’s memory, and optimistic about the results it may deliver.
