Raymond B. Mailhot, M.D.

I see patients with childhood cancers, blood cancers, and breast cancer. I serve as Director of the University of Miami Pediatric Radiotherapy Program, serve as Medical Director of the Dwoskin Proton Therapy Center, and am Physician Lead of the Adolescent Young Adult Cancer Survivorship Program for the Sylvester Comprehensive Cancer Center. These leadership positions all underscore my career emphasis on reducing late effects for cancer survivors and improving cancer survivorship for children, adolescents, and young adults. I trained at Washington University in Saint Louis, Harvard University, and New York University.
To date, I have authored more than 80 peer-reviewed publications across childhood cancer, Hodgkin lymphoma, and breast cancer in leading journals such as JAMA Oncology, Nature Medicine, and Journal of Clinical Oncology. My research program has been supported by seven extramural grants totaling over $4 million. I currently serve as the contact Principal Investigator for an NCI-funded R37 MERIT award—an honor reserved for highly competitive and impactful projects. My work has been recognized nationally and internationally, including selection for the American Society for Radiation Oncology’s Best of ASTRO designation and the Young Investigator Award at the 61st International Meeting of the Particle Therapy Co-operative Group (PTCOG). In addition, I was one of the few investigators chosen for the NCI’s inaugural Early Investigator Advancement Program (EIAP) and have served as a reviewer for three NIH Study Sections.
My laboratory was the first in the United States to establish a direct linkage between patients’ electronic medical records and their public school data—sources protected respectively by HIPAA and FERPA. This groundbreaking integration allows us to understand how cancer and its treatments affect not only survival, but also academic and social reintegration for children and adolescents. We were the first group worldwide to identify and report correlations between radiation dose to critical brain regions and subsequent school performance. This work was funded by the Florida Department of. Our ongoing studies aim to clarify how cancer therapies influence educational outcomes and quality of life. In recognition of this work, I received the 2025 Transformative Medicine Award from the University of Florida Department of Radiation Oncology.

My current NCI and Leukemia & Lymphoma Society–funded projects focus on reducing disparities in outcomes among Hodgkin lymphoma survivors from communities in need. Through a novel data linkage between PCORnet and the CIBMTR—the largest national repository of transplant data—my team is examining how differential access to therapy and survivorship care contributes to survival inequities. This mixed-methods research integrates quantitative analyses with qualitative interviews conducted in partnership with AYA patient advocacy groups, including the Leukemia & Lymphoma Society, Stupid Cancer, Elephants & Tea, and the Cactus Cancer Society as advocates and recruitment partners.
I hold several national leadership positions, including appointments to the Children’s Oncology Group Hodgkin Lymphoma Steering Committee, the American Radium Society/American College of Radiology Appropriate Use Criteria Committee in Lymphoma, and the NRG Oncology Breast Committee.
My research and advocacy have been featured by Conquer Cancer, the ASCO Foundation, which published a profile of my work on equity and inclusion in cancer care and invited me to host their Childhood Cancer Awareness Month podcast—the first physician invited to directly interview a patient survivor: https://www.conquer.org/impact/your-stories/auburn-frymire-and-dr-raymond-mailhot. My educational research has received extramural funding to evaluate interventions that reduce global childhood cancer disparities. The Sociedad Mexicana de Radioterapeutas (SOMERA or Mexican Society for Radiotherapy) named me a 2021 Ambassador for my contributions to their pediatric radiotherapy training and collaboration, which expanded to projects in Saudi Arabia and Colombia. I continue to teach for SOMERA and led their continuing education lecture on Hodgkin lymphoma in September 2025. My international leadership has also been recognized by the International Atomic Energy Agency, where I have led the global survey on pediatric radiotherapy capacity, selected for oral presentation at ASTRO 2025.
