Elena Ladas

Dr. Elena J. Ladas is the Sid and Helaine Lerner Professor of Global Integrative Medicine in the Division of Pediatric Hematology/Oncology/Stem Cell Transplant at Columbia University Irving Medical Center (CUIMC). Dr. Ladas is a clinical investigator with an expertise in the clinical integration and scientific evaluation of nutrition and complementary/ alternative medicine in pediatric oncology. Dr. Ladas is the principal investigator on a number of multi-institutional studies that evaluate the role of nutrition and integrative therapies, as components of supportive care, during and after treatment for childhood cancer. Specifically, she is evaluating the influence of dietary intake on the development of nutrition-related morbidities (such as obesity) in children with acute lymphoblastic leukemia and is the principal investigator of an R01-funded study that is investigating the role of probiotic therapy on the development of gastrointestinal acute graft-versus-host disease among children and adolescents undergoing hematopoietic cell transplantation. Dr. Ladas also leads a multi-institution study evaluating the clinical effects of perturbations to the microbiome among children with acute lymphoblastic leukemia.

Dr. Ladas is the founder and director of the International Initiative for Pediatrics and Nutrition (IIPAN) at CUIMC, which aims to enhance nutritional capacity and high-quality research among pediatric cancer units in low- and middle-income countries. IIPAN’s programs are established in Central and South America, Asia, and Africa. This initiative is active in 34 hospitals located in 17 countries and supports nutritional care for nearly 9,000 newly diagnosed children each year. In 2019, Dr. Ladas formalized a collaboration with the International Agency for Research on Cancer, World Health Organization (Lyon, France). IIPAN and IARC will be leading a multi-national nutrition bio-banking program evaluating nutritional anthropometrics, the microbiome, and lifestyle behaviors on short- and long-term clinical outcomes in children with cancer.
