Dr Irene Chong has both a private and an NHS practice at The Royal Marsden. She is a Clinical Oncology Consultant at The Royal Marsden NHS Foundation Trust and a Clinician Scientist at The Institute of Cancer Research. She trained at St Bartholomew’s Medical College, London, and undertook her PhD in Cancer Biology at the ICR. She specialises in the treatment of upper and lower gastrointestinal malignancies.

Dr Chong works in The Royal Marsden’s Gastrointestinal Clinical Trials Unit where she develops biomarker-driven, proof-of-concept clinical trial protocols based on discoveries made in the laboratory. Her laboratory research aims to discover new therapeutic targets and biomarkers for oesophageal and rectal cancers through DNA sequencing and functional profiling.

She collaborates closely with The Royal Marsden’s Rectal Cancer Study Group and the Pelican Cancer Foundation to identify radiological and molecular predictors of response to chemotherapy and radiotherapy for patients with rectal cancer, and to establish new therapeutic targets that could be exploited in combination with radiotherapy to improve treatment.

Dr Chong received several awards during her PhD, including the University of London Scholarship Award, the Fourth NIHR Infrastructure Experimental Medicine Research Award, and the Royal College of Radiologists Kay Visiting Award.
