Dr Nick Maisey 


Consultant Medical Oncologist

I am a consultant in Medical Oncology at Guys and St Thomas’ NHS Foundation Trust (GSTT).

I currently lead Medical Oncologist for oesophago-gastric cancer at GSTT and have held a number of key roles including service lead for colorectal cancer, vice chair of the upper gastrointestinal tumour working group and medical director for the South East London Cancer Network. I am currently a core member of the Oesophago-gastric priority group for the London Cancer Alliance, overseeing the delivery of care across North-West, South-West and South-East London.

I am also a core member of the Carcinoma of unknown primary team at Guys and St Thomas and have been instrumental in developing the service of treatments and pathways for this rare cancer.

I am involved in cancer drug development and has been a principal investigator on a number of national clinical trials as well as commercial studies.

After qualifying in 1993 from Guys and St Thomas’ Hospital, I became a member of the Royal College of Physicians 1997. I completed my specialist training in medical oncology at the Royal Marsden Hospital. During my specialist training I was successful in a competitive grant from the National Cancer Institute to perform research at the Institute of Cancer Research in London. In 2002 I was awarded an MD thesis for my work on early response markers in Cancer.
