The University of Arizona Cancer Center Neuro-Oncology Multidisciplinary Clinic encompasses physicians with expertise in neuro-radiology, neuro-pathology, neuro-surgery, neuro-oncology, medical oncology and radiation oncology.
This diverse team of experts collaborates to develop innovative treatments for both primary and secondary brain tumors. Learn more about brain tumors.
Meet the Team
Sometimes the treatment team will decide to biopsy the tumor after it has been surgically removed. In this instance, a neuro-surgeon strategically removes the tumor while preserving surrounding normal tissue, and then sends a portion of the tumor to the pathology department for review.
G. Michael Lemole, MD, is the head of neuro-surgery. He earned his medical degree at University of Pennsylvania School of Medicine, completed his residency at Barrow Neurological Institute (Neurological Surgery) and completed fellowships at Barrow Neurological Institute (Spinal Surgery), Barrow Neurological Institute (Cerebral Vascular/Skull Base), and Christian-Doppler Medical Center (Endovascular/Cerebrovascular Surgery).
Dr. Abhay Sanan is a neuro-surgeon with a particular interest in skull base tumors, cerebrovascular lesions and functional disorders such as trigeminal neuralgia. He earned his medical degree at Boston University School of Medicine, and completed a fellowship at the University of Cincinnatti in complex intracranial surgery. Dr. Sanan specializes in surgical treatment of disorders of the central and peripheral nervous system.
The first step in diagnosing brain tumor is either a CT scan, where an x-ray machine takes detailed images of the brain, or an MRI where magnetic resonance imaging is reviewed on a computer screen.
Dr. Raymond Carmody is a professor of radiology at the Arizona Health Sciences Center. He earned his medical degree from Indiana University Medical Center, and his research focuses on orbital pathology. As a neuro-radiologist, Dr. Carmody specializes in the diagnosis of abnormalities of the central and peripheral nervous system, with a particular interest in orbital imaging and ENT radiology.
After a diagnosis is confirmed via either CT or MRI, a biopsy is taken from the tumor. This is achieved either through a needle aspiration, or the neuro-surgeon will send a portion of the tumor to pathology following surgical removal.
Dr. Naomi Rance is a professor in the Department of Pathology, Cell Biology and Anatomy and Neurology at the University of Arizona College of Medicine. She earned her medical degree and doctorate from the University of Maryland. Dr. Rance's research focuses on neuro-endocrinology and hypothalmic gene expression. As a neuro-pathologist, Dr. Rance specializes in the study of disease of nervous system tissue, aiding in the diagnosis of disease, and tumor histology.
Chemotherapy is often used in conjunction with surgery and radiation to destroy brain tumor cells. A neuro-oncologist is either a neurologist with subspecialty training in oncology, or an oncologist with special neurologic training.
Dr. Michael Badruddoja is currently the only neuro-oncologist in southern Arizona. He was previously assistant professor of medicine at the UCLA David Geffen College of Medicine and neuro-oncologist at the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Institute. As a neuro-oncologist, Dr. Badruddoja specializes in the use of chemotherapy for medical management of primary and metastatic central nervous system neoplasms.
In addition to the neuro-oncologist, another vital member of the treatment team is the medical oncologist.
Maria Bishop, MD, is a medical oncologist and associate professor in clinical medicine. She earned her medical degree at the University of Arizona. Her research is focused on developing and evaluating a curriculum for end-of-life care, and she is a board member for Passages, a community program providing end-of-life education and support. As a medical oncologist, Dr. Bishop specializes in the use of chemotherapy for medical management of neoplasms.
Sarah Kratz, MD serves as assistant professor of clinical medicine at The University of Arizona College of Medicine.
Dr. Kratz received her medical degree from University of North Carolina School of Medicine. She completed a residency in internal medicine and radiation oncology at Duke University Medicine Center, and completed a fellowship in hematology/oncology and radiation oncology at Duke University Medical Center. Dr. Kratz is certified by the American Board of Internal Medicine with a subspecialty in Medical Oncology. She speaks Spanish.
Radiation therapy is often used in conjunction with chemotherapy when treating brain tumors.
Baldassarre Stea, MD, PhD, is professor and chair of the Department of Radiation Oncology at the University of Arizona. He earned his doctorate from UCLA and his medical degree from George Washington University. Dr. Stea developed the stereotactic radiosurgery program at the University of Arizona, and has over 20 years experience in this field. As a radiation oncologist, Dr. Stea specializes in the administration of radiation for the treatment of various cancers, with a focus on primary brain tumors, such as glioblastoma multiforme.
