Obesity has been identified as an adverse risk factor for survival in many adult and childhood cancers, but not in pediatric Hodgkin lymphoma, the most common cancer in adolescents. The results of a study led by researchers at Roswell Park Cancer Institute (RPCI) and Columbia University Medical Center used advanced imaging methods to evaluate obesity and suggest a relationship between obesity and disease relapse. The team’s findings will be presented at the American Society of Clinical Oncology (ASCO) 52nd Annual Meeting in Chicago.

Primary immunodeficiency disorders are a group of more than 300 single gene defects that affect the role of the immune system and prevent it from functioning properly. When Roswell Park Comprehensive Cancer Center researchers evaluated the overall and site-specific incidence of cancer among patients registered in the United States Immune Deficiency Network (USIDNET), they found increased cancer incidence rates among patients with primary immunodeficiency diseases — and, in particular, a significant increase in lymphoma cases. The team’s findings will be presented at the American Society of Clinical Oncology (ASCO) 52nd Annual Meeting in Chicago.
