Dr Rik Bryan is a former clinical urologist and now a full-time research academic with a strong interest in bladder cancer. In particular he is focused on defining the immune microenvironment of bladder tumours, and in understanding and improving BCG immunotherapy approaches that are currently used to treat the disease.

Background and Research focus
Mr Bryan is a former clinical urologist and now full-time research academic with a broad bladder cancer interest, from optical technologies, surgical techniques and chemoprevention trials to biomarker discovery, cadherin biology, and molecular pathways.
In particular, his research encompasses three streams of interest which include urinary biomarkers, narrow band imaging cystoscopy and BCG immunotherapy. Bladder cancers are diagnosed and followed-up using a combination of cystoscopic examination, cytology and histology. These are not only invasive and expensive, but also highly subjective investigations that reveal limited molecular insights into bladder cancer biology. With this in mind, Dr Bryan and his collaborators have identified several bladder cancer biomarkers using proteomic and epigenomic approaches, and are currently investigating their effectiveness in diagnosing and predicting recurrence and progression. The treatment options for bladder cancer largely depend on how advanced the tumour is and its grade of aggressiveness. A common approach after surgery is to treat patients’ bladders with a variant of the BCG vaccine to prevent recurrence of bladder cancer. However, it is unclear how the BCG vaccine works. Dr Bryan in collaboration with Dr Graham Taylor is interested in understanding the responses to BCG therapy with the aim of improving the intravesical BCG approaches currently used to treat bladder cancer.
Accompanying this research is a comprehensive molecular evaluation of the immunological milieu of the bladder tumour microenvironment. He is also investigating the use of narrow band imaging cytoscopy in bladder tumour resection and subsequent disease surveillance. This technique is an important recent development within urology that has shown considerable promise in enhancing detection and thus reducing recurrence and progression of bladder tumors by improving the completeness of bladder tumour resection and improving the sensitivity of surveillance.

Rik is the Chief Investigator of the Bladder Cancer Prognosis Programme (BCPP), which has recruited over 1500 bladder cancer patients since its launch in 2005. The BCPP has established one of the world’s largest bladder cancer biospecimen collections providing a unique resource for a wide array of bladder cancer studies. In addition to his research, Rik has made substantial contributions to organization and teaching on various taught programmes at the University of Birmingham. In particular, he leads the “Cancers of the Urogenital Tract – Background, Controversies, and Future Directions” module on the MBChB course (Year 2) as well as the “Clinical Challenges” module on the new MSc in Translational Medicine. He is also a reviewer for a number of urology and basic science journals, and sits on the committees of The Royal Society of Medicine Section of Urology, Action on Bladder Cancer, the “T2 and Below” subgroup of the NCRI Bladder Cancer Clinical Studies Group and a number of international clinical trials.
