Northwell Health Imbert Cancer Center
Gerardo Jerry Vitiello, MD, joined Northwell Health as an academic surgical oncologist in 2023. He specializes in treating liver, bile duct, gallbladder, pancreas and stomach cancer, as well as melanoma and soft tissue sarcomas including gastrointestinal stromal tumor. An avid baseball player growing up, Dr. Vitiello started medical school at Emory University thinking he d go into orthopedics, but surgical oncology clicked for him during his third year. I liked the critical thinking aspect of being a surgical oncologist; it wasn t can we do more? but rather when and how can we optimize treatment for this person? I also liked approaching care in terms of the whole body, not just one specific location. After completing a residency at NYU Langone Health and a fellowship at Memorial Sloan Kettering Cancer Center, he was drawn to the Northwell Health Cancer Institute for its one-stop approach to cancer treatment. All consultations and appointments are set up in one visit, which streamlines the process for patients, he says. And our team meets weekly to get multi-disciplinary feedback on each patient case so that everyone is on the same page and next steps are expedited. Dr. Vitiello has published more than 30 research manuscripts and is working with other oncologists and Cold Spring Harbor Laboratory scientists to study the role of systemic immune and metabolic responses to cancer. I really enjoy finding information to push the field forward. How can I improve the lives of my patients and everyone else too? Cancer therapy is dynamic, and we re always learning more. In addition to research, empowering his patients is what inspires Dr. Vitiello day to day. When someone learns they have cancer, their biggest fear is the loss of control. Feeling at the mercy of the disease and being overwhelmed with information is very stressful. In my first meeting with a patient, I focus on creating a clear and simple plan regarding next steps and things that they can control. He works with patients on holistic aspects of care such as diet and exercise, referring them to specialists if necessary. The idea is to get them in the best possible shape to fight the cancer and tolerate the treatment, he says. At the end of the day, my goal is to get to the post-operative conversation with good news. The thrill of saying, We did the right things and here s the proof , that s what really drives me. Dr. Vitiello is rated as an Advanced provider by MediFind in Kidney Transplant. His top areas of expertise are Gastrointestinal Stromal Tumor, Stomach Cancer, Fibrosarcoma, Pancreaticoduodenectomy, and Tissue Biopsy.
