“For the first 15 years of my career, we had nothing new” in bladder cancer care, said Jonathan E. Rosenberg, MD, chief of the genitourinary oncology service at Memorial Sloan Kettering Cancer Center in New York City. Now, “the pace of change has been dizzying,” he told Robert A. Figlin, MD, the interim director of Cedars-Sinai Cancer in Los Angeles and Steven Spielberg Family Chair in Hematology-Oncology. Speaking at the 2025 American Society of Clinical Oncology Annual Meeting, Dr. Rosenberg discussed key studies that have recently changed practice and what questions still remain. For certain laboratory testing and other concerns, “it’s a bit of the Wild West right now,” he noted.
