GOSH provided Alice's probable diagnosis within a day and commenced the diagnostic process involving a biopsy, lumbar puncture, blood tests and PET scans. Full diagnosis revealed that Alice had stage 4 alveolar rhabdomyosarcoma with the primary tumour attached to the submandibular gland in her neck with positive lymph nodes and a tiny tumour in her lung. Her treatment begun immediately as the tumour was compromising her airway.

Alice was treated under the care of GOSH and Jacksonville, University of Florida Health Proton Therapy Institute. She received a combination of intensive in-patient chemotherapy, out-patient maintenance chemotherapy and radiation over a period of almost two years. The treatment involved spending 11 weeks in Florida receiving proton radiation which is currently unavailable in the UK. Proton radiation is a highly targeted form of radiotherapy - the proton beams kill the cancer cells and cause less damage to surrounding healthy tissues. This is particularly relevant to young children so that long term damage can be limited. When Alice relapsed she had chemotherapy at GOSH and travelled to the Emma Children's Hospital in Amsterdam for AMORE which involved surgical removal of the tumour, brachytherapy and reconstruction.

Throughout the journey Alice’s parents met a worldwide network of medical professionals and families with children undergoing cancer treatments. They became increasingly aware of the lack of funding and clinical research in to the treatment of children’s cancers. And so Alice’s Arc was born with a commitment to help find a cure with less toxic treatment options.
