Dr. Louis Lacombe is a urologist-oncologist and clinical researcher at the CHU de Québec, and more specifically at L’Hôtel-Dieu de Québec.

Dr. Lacombe completed his medical training in Sherbrooke in 1988 and then completed a specialization in Urology at Laval University in 1993. Subsequently, Dr. Lacombe traveled to New York at the Memorial Sloan-Kettering Cancer Center associated with Cornell University to perform a subspecialisation in uro-oncology. This subspecialisation ended in 1996.

Following this subspecialisation, Dr. Lacombe joined the Urology Department of the CHU de Québec in July 1996. As a urologist, Dr. Lacombe specializes in complex surgeries associated with prostate, kidney, testicular and bladder cancer. He also collaborates in kidney transplant surgery.

Research at the Experimental Uro-oncology Laboratory aims to improve the diagnosis, prognosis, and therapy of prostate, bladder, and kidney cancers, and thus cover many aspects of research, from basic research to applied research. His interest is mainly focused on bladder cancer.

Dr. Lacombe is also actively involved in clinical research by conducting numerous Phase I, Phase II or Phase III clinical trials to test new drugs or therapies. He has been the principal investigator or co-investigator in more than 120 studies since the beginning of his career.

He has published more than 110 scientific papers and more than 250 scientific abstracts, and has presented at many international conferences.

Throughout his career, he has been awarded the FRQS Junior I and II Clinician Fellowship. He is currently a full professor in the Department of Surgery, and since 2016 he is the Director of the University Department of Surgery at the School of Medicine at Laval University.
