Prof Ajay Aggarwal

Prof Cancer Services & Systems Research

United Kingdom

I am a Consultant Clinical Oncologist (specialising in the delivery of radiation and systemic cancer therapies) at Guy’s & St Thomas’ NHS Trust, London and Professor of Cancer Services and Systems Research at the London School of Hygiene and Tropical Medicine (LSHTM).

I am the Clinical Director for the ten national cancer audits in England and Wales (NATCAN) and a member of the Executive Committee for the European Cancer Organisation. I have been the recipient of two fellowship awards from the National Institute for Health Research in 2014 and 2020 and is the current Editor-in-Chief of the Journal of Cancer Policy.

In my role as the clinical lead for the UK National Prostate Cancer Audit, I led the development and delivery of the first ever national hospital outcome reporting programme for radiotherapy. My research has also contributed significantly to national and international policy discussion around the affordability of cancer care and the value of new technologies in cancer medicine which has influenced directly the WHO Cancer Drug Pricing and Benefits Taskforces. As co-chair of the Health Economics in Radiation Oncology (HERO) group within ESTRO (European Society for Radiation Oncology), I am leading the value-based health care initiative.

I have previously worked at the World Health Organisation in Geneva and currently the Chief Investigator of the NIH funded ARCHERY study, the first prospective international multicentre trial across India, Jordan, Malaysia and South Africa evaluating the role of AI in the delivery of radiotherapy treatment.

I graduated from Guy’s, Kings’ & St Thomas’ Medical school having attained a BSc in Management at Imperial College London. I have an MSc in the Science of Cancer from The Institute of Cancer Research and an MSc in Health, Population and Society from The London School of Economics. I completed my PhD in Health Services and Policy Research at LSHTM.
