Dr. André-Guy Martin is a clinical radio-oncologist and brachytherapy specialist with the CHU de Québec radio-oncology Department. He is also a research associate at the Centre de recherche du CHU de Québec-Laval University, Oncology Axis, affiliated with the Laval University Cancer Research Center.

Having graduated with a PhD in radio-oncology from Laval University in 2002, he went on to train in brachytherapy and obtained a Fellowship in Brachytherapy from the Brigham and Women’s Hospital of the prestigious Harvard Medical School in Boston, Massachusetts, U.S.A. He also completed a master’s degree in experimental medicine (MSc) focusing on prostate brachytherapy through the I-125 implant. He has been practicing brachytherapy since, and is mainly interested in urological and digestive sites (brachytherapy of the esophagus and rectum).

His area of interest in research focuses mainly on imagery-guided, concentrated brachytherapy. Along with his team, he has added the new modalities of magnetic resonance imagery and is working on setting up an automated guidance system. Thanks to his previous training in pharmacology, he has developed new pharmacotherapeutic avenues (cytoreduction) to optimize the brachytherapy approach. He contributes to and locally directs the NRG protocols.

Very involved in his area of research, he is the co-editor of the Contemporary Journal of Brachytherapy. On the provincial level, he is treasurer for l’Association des radio-oncologues du Québec. Internationally, he also supports the Groupe Francophone de Radiothérapie en Urologie.
