Dr. Matthew Dallos

Dr. Matthew Dallos, MD, is a medical oncologist specializing in genitourinary cancers, with a primary focus on prostate cancer. He practices at Memorial Sloan Kettering Cancer Center, where he works closely with a multidisciplinary team of urologists, radiation oncologists, and nurses to deliver comprehensive, personalized care. Dr. Dallos is deeply committed to the patient-physician relationship, approaching each patient through careful listening to understand their hopes, goals, and priorities before collaborating on an individualized treatment plan. His overarching goal is to connect patients with the most advanced available treatments while improving their quality of life and minimizing treatment-related side effects.

As a clinical and translational researcher, Dr. Dallos designs and leads clinical trials aimed at expanding treatment options for patients with prostate cancer. His specific area of research expertise is immunotherapy, with a focus on developing therapies that activate the immune system against cancer. While immunotherapy has transformed outcomes in many other cancer types, its full potential in prostate cancer remains an active area of investigation. To address this, Dr. Dallos studies the genetic and molecular characteristics of prostate tumors to optimize immune-based approaches, working in close collaboration with an interdisciplinary group of scientists in immunology, systems biology, urology, and pathology. The central aim of his research is to identify new immune targets and translate these discoveries rapidly into clinical advances that improve outcomes for patients with prostate cancer.

Beyond his clinical and research work, Dr. Dallos is known for his patient-centered philosophy and his belief that a cancer diagnosis has a profound impact on every aspect of a person's life. He offers patients access to a broad range of cutting-edge clinical trials at MSK alongside established treatment options, ensuring each individual benefits from the latest scientific progress. Outside of work, he enjoys running, cycling, and hiking throughout the New York City tri-state area, exploring science fiction, and spending time with family and friends.
