Memorial Sloan Kettering is home to the multidisciplinary Pituitary and Skull Base Tumor Center, which brings together doctors from a range of specialties to provide world-class, comprehensive care to patients who have been diagnosed with pituitary, parasellar, paranasal sinus, and other skull base tumors.
One of the most important aspects of the center is its multidisciplinary nature. Patients receive personalized care from a team of experts that includes a neurosurgeon, head and neck surgeon, neuro-endocrinologist, radiation oncologist, neuro-oncologist, and neuro-radiologist.
Because our team works so closely together, we are able to relieve patients from the burden of coordinating care. For example, someone who needs to see a neurosurgeon, a head and neck surgeon, and a neuro-endocrinologist can do so all at the same time during our pituitary tumor clinics. This approach spares our patients from having to go to multiple appointments over the course of weeks or even months. It also allows us to develop a personalized care plan right away.
