Roman Kizyma is a pediatric oncologist and the General Director of the Clinical Center for Children’s Medicine in Lviv, a major pediatric oncology and bone marrow transplant hub in Western Ukraine. Under his leadership, the center has become a critical regional referral point for children with cancer, especially during the ongoing conflict in Ukraine, providing care to displaced children from frontline regions.
Dr. Kizyma is a co-founder of SAFER Ukraine, a collaborative initiative with St. Jude Children’s Research Hospital, which coordinates the triage and evacuation of children with cancer to specialized care facilities across Europe. This program ensures continuity of life-saving treatment for children affected by wartime disruptions.
He has participated in international pediatric oncology training programs, including St. Jude Global, and is involved in research on improving sustainable pediatric cancer care in Ukraine. Dr. Kizyma’s work demonstrates a model of resilience and regional coordination in pediatric oncology, bridging emergency response and long-term healthcare development in conflict settings.
