Dr Henry Mandeville

I am a consultant clinical oncologist specialising in the treatment of malignancies in children and young people. I qualified from the University of Aberdeen in 1997 and trained in Clinical Oncology in London, at St Bartholomew’s and Hammersmith Hospitals. In 2011, I was awarded an MD(Res) from UCL following a Cancer Research UK clinical research fellowship at Mount Vernon Hospital and the Gray Cancer Institute. I specialised in paediatric radiotherapy, working at University College Hospital and Great Ormond Street Hospital.

Since December 2011, I have worked as a consultant clinical oncologist in the children and young people’s unit and the haemato-oncology unit at The Royal Marsden Hospital. In May 2024, I was appointed as a consultant paediatric and adolescent clinical oncologist at the UCLH Proton Beam Therapy Centre.

My main research interests focus on technical radiotherapy improvements for tumours in children and young people. These include respiratory-related motion management, rotational intensity-modulated radiation therapy (IMRT), MRI-guided radiotherapy, and proton beam therapy, as well as the impact of local therapy on the quality of life of survivors.

I served as Chair of the European Paediatric Soft Tissue Sarcoma Group (EpSSG) Radiotherapy Committee from 2013 to 2020 and was a member of the EpSSG Board from 2018 to 2024. I am also the Local Therapy Lead for the new EpSSG Frontline and Relapsed Rhabdomyosarcoma (FaR-RMS) study and Chair of the NCRI Young Onset Soft Tissue Sarcoma Subgroup.
