Dr Andreyev qualified in 1987 from the Royal London Hospital. He completed a PhD in 1997 at the Institute of Cancer Research and The Royal Marsden. His training in gastroenterology was mainly in London, including St Mark's and the Hammersmith Hospitals. In 2000 he was appointed a senior lecturer at Imperial College and was an honorary consultant gastroenterologist at Chelsea and Westminster Hospital and The Royal Marsden. He left Imperial College in 2005 and subsequently has worked solely as a consultant at The Royal Marsden.
He is the only consultant appointed specifically to treat the side effects of cancer treatments, particularly radiotherapy. He has the largest practice in the UK of such problems, seeing more than 500 new patients a year.
In addition to his clinical work he runs a busy research programme exploring better and novel ways of:
- identifying and measuring bowel side effects of cancer treatments
- preventing bowel side effects
- treating bowel side effects
In the last ten years he has published more than 50 original peer-reviewed papers about gastrointestinal treatments related to cancer treatment, and has organised and run randomised trials exploring strategies to improve outcomes, enrolling more than 1,000 patients.
He is active at a national and international level in attempting to educate health professionals and to define new standards for the management of bowel problems arising as a result of cancer treatment. He is regularly invited to speak at meetings around the UK, and in Europe and the USA.
