The 30th Congress of the European Hematology Association (EHA 2025) was held from June 12 to 15 in Milan, Italy. As one of the world’s leading hematology meetings, this year’s event spotlighted the latest advances across hematologic subspecialties, featuring cutting-edge approaches in diagnosis and treatment, along with new findings in both clinical and translational research. Among the studies presented, a research project led by Professor Jian Hou from Renji Hospital, Shanghai Jiao Tong University School of Medicine, was selected for an oral presentation (Abstract S188). This study sheds light on the critical role of non-coding enhancer-type extrachromosomal circular DNA (eccDNA), specifically eccANKRD28, in the development of drug resistance in multiple myeloma (MM). Oncology Frontier – Hematology Frontier spoke with Prof. Hou onsite for an in-depth discussion of this work.
