“Heading back from Madrid and the ESMO – European Society for Medical Oncology Congress 2026, where I was reminded once again of the power of collaboration and the importance of building connections across our global oncology community.
A highlight was participating in the ESMO/ASCO Joint Session, ‘The Evolving Definition of the Modern Oncologist.’ I had the opportunity to discuss how oncologists must increasingly serve not only as clinical experts, but also as leaders of multidisciplinary teams navigating the growing complexity of cancer care. It was a wonderful opportunity to amplify my American Society of Clinical Oncology (ASCO) Presidential theme: ‘Intentional Teams. Exceptional Care.’ As cancer care becomes more sophisticated, our ability to deliver exceptional care will depend not only on scientific advances, but also on how intentionally we bring together, support, and lead the teams delivering that care.
Equally meaningful was the opportunity to meet with ASCO and ESMO leadership – Julie Gralow, Julia Close, Douglas Pyle, Brian Bourbeau, Fabrice André, and Giuseppe Curigliano – to discuss how ASCO and ESMO can strengthen our collaboration to advance cancer care worldwide. Our organizations share a commitment to improving outcomes for patients with cancer, and I am excited about the opportunities to leverage our collective expertise, resources, and global reach to make an even greater impact.
I also appreciated the opportunity to connect with representatives from ECO (Foundation for Excellence and Quality in Oncology) and learn more about our shared interests in ensuring quality in cancer care.
Another particularly rewarding moment was reconnecting with junior faculty who previously participated in ASCO’s International Development and Education Award (IDEA) program. Seeing these talented oncologists advancing in their careers is a powerful reminder of the lasting impact of investing in the next generation of oncology leaders.
I’m leaving Madrid energized by the science, inspired by the people, and grateful for the partnerships that connect our global oncology community.
The future of cancer care will be shaped by scientific innovation – and by the teams, leaders, and collaborations that bring that innovation to patients.”
