Summary of Research

Dr. Lafay-Cousin’s primary area of clinical research is in pediatric brain tumors, with a specific interest in brain tumors occurring in very young children such as medulloblastoma, atypical teratoid rhabdoid tumor (ATRT) and choroid plexus tumors. She is the past chair of the Children Oncology Group clinical trial ACNS 1221 for desmoplastic medulloblastoma in young children. She has developed the Canadian Registry of Atypical Teratoid Rhabdoid Tumors which led to significant clinical contribution to the identification of prognostic factors and therapeutic targets of this disease. She is also interested in other rare brain tumors like intracranial germ cell tumors and the long term follow of survivors of brain tumors.
