Elena Ladas


I am a clinical nutritionist specializing in supportive care in pediatric oncology and hematopoietic cell transplantation (HCT). My clinical and scientific expertise lies in the application of novel therapies to improve the current range of supportive nursing interventions in pediatric oncology and HCT. My research has focused on clinical research studies examining the role of nutrition or integrative therapies (IM) as part of existing supportive nursing interventions. I chair the Nutritional Committee of the Children's Oncology Group (an NCI-funded collaborative clinical study group) and a member of the NCI PDQ Advisory Board for Complementary / Alternative Medicine. Each of these roles offers me the necessary infrastructure and support to conceptually develop and implement clinical research studies. My long-term goal is to develop evidence-based, supportive clinical models and guidelines that incorporate the best of conventional, nutritional and integrative medicine. This research objective aims to promote the provision of supportive care interventions that: (1) improve quality of life during and after cancer treatment, (2) reduce treatment-related toxicities, and improve survival; and (3) facilitate the delivery of supportive care services across the spectrum of cancer care.

International Pediatrics and Nutrition Initiative (IIPAN) : Dr. Ladas and colleagues are working with the Hematology-Oncology Unit, Advanced Pediatrics Center at the Post Graduate Institute of Medical Education and Research (PGIMER) in Chandigarh to establish uniform levels of care by validating the nutritional algorithm. The children participating in this study will be recruited by PGIMER and the research will be supported by local investigators in Chandigarh. In collaboration with the Tata Memorial Hospital in Mumbai, the IIPAN and its staff are evaluating the effects of malnutrition on the development of sarcopenic obesity in Indian children with acute lymphoblastic leukemia (ALL). The study examines lifestyle factors, genetics, and demographic variables in Indian children and adolescents with ALL. Participants in the study will be children and adolescents being treated at Tata Memorial Hospital, the largest pediatric cancer center in South Asia. International Pediatrics and Nutrition Initiative (IIPAN) : CUMC is partnering with Unidad De Oncologica Pediatrica (UNOP) in Guatemala City, the only academic pediatric cancer center in Guatemala that serves more than 400 cases annually, to investigate the role of nutritional status in treatment outcomes in children with acute lymphoblastic disease Leukemia (ALL). The aim is to determine the relationship between nutritional status, physical activity and body composition and clinical outcomes in children undergoing ALL treatment. International Pediatrics and Nutrition Initiative (IIPAN) : About 500 new cases of neuroblastoma are diagnosed in Brazil every year.
