IEO (European Institute of Oncology)
Founded by Umberto Veronesi, pioneer of breast-conserving surgery and sentinel node biopsy.
Overview
IEO, the European Institute of Oncology in Milan, was founded by Umberto Veronesi, the surgeon who pioneered breast-conserving surgery and sentinel lymph node biopsy, and it ranks eleventh in the Newsweek/Statista World's Best Specialized Hospitals list for oncology. Its strengths are breast surgery de-escalation, early-phase drug development under Giuseppe Curigliano, and HER2-low and antibody-drug conjugate research, with Paolo Veronesi, Roberto Orecchia, Nicoletta Colombo and Pier Giuseppe Pelicci among its leaders. OnCo links it to triple-negative and HER2-positive breast cancer, to Fondazione AIRC, and to the Organisation of European Cancer Institutes. How much further surgery and radiotherapy can safely be scaled back in early breast cancer is the question it keeps testing. Its breast programme is the one to read.
