Dr Andrew Gaya



Dr Gaya originally qualified at St George’s Hospital Medical School (University of London) where he was awarded a distinction and several academic prizes. He trained in Clinical Oncology at Imperial College and St Bartholomew’s Hospital and subsequently undertook a Cancer Research UK MD Fellowship at University College London.

Dr Gaya treats solid tumours using chemotherapy, radiotherapy, and biological therapy – His main focus is on colorectal cancer, cancers of the oesophagus, stomach, pancreas, liver, and lung cancer. Dr Gaya’s main research interest is in the area of functional cancer imaging, where he is looking for ways to assess response to treatment much earlier and techniques for assessing blood flow and oxygen levels within cancers.

He is also heavily involved with the implementation of the latest radiotherapy techniques such as IMRT, IGRT and Tomotherapy, combining targeted or anti-vascular drugs with radiotherapy, and stereotactic body radiosurgery. He is one of the first UK doctors to use the CyberKnife stereotactic body radiosurgery unit. He has published widely in peer-reviewed journals, and is currently lead clinical oncologist for audit and clinical governance at Guy’s and St Thomas’ NHS Foundation Trust.
