This month the PNA Spotlight focuses on Dr. Sandeep Kunwar, an eminent neurosurgeon who serves on the PNA’s Board of Directors. He is surgical director of the California Center for Pituitary Disorders and a professor of neurosurgery at UCSF. He is also surgical director at the Taylor Bell Neuroscience Institute in the Washington Hospital Healthcare System in Fremont, CA. He opened his private practice there in 2006. He received a Bachelor of Arts degree from UC Berkeley in 1988. From 1991-2 he trained as a Howard Hughes Medical Institute Research Scholar at the National Cancer Institute, working in the laboratory of molecular biology. He went to graduate from UCSF medical school in 1993, did his residency there in neurological surgery in 1998, and joined the faculty upon completion in 1999. From 1997-98 he served as a Research Fellow in the Brain Tumor Research Center at UCSF. He was selected by renowned pituitary surgeon Dr. Charles Wilson to take over his practice upon retirement.
Dr. Kunwar specializes in gamma knife radiosurgery for metastatic and primary brain tumors, and uses the endonasal approach for pituitary tumors. His research works to improve surgical therapy for brain tumors, particularly glioblastomas. He has pioneered a minimally invasive surgical technique for skull-based tumors and has successfully applied that skill to transcranial and spine patients as well. He was kind enough to answer questions from the PNA. His responses follow.
This month the PNA Medical Corner showcases and article co-authored by Dr. Jason Sheehan, a longtime member of the PNA. The study, published in the journal Neurosurgery, reviews the literature on stereotactic radiosurgery for secretory pituitary adenomas. The authors conclude that SRS is effective most of the time in controlling the tumor but is less effective at improving endocrine function or at achieving remission.

Study: MRI May Not Detect 1/3rd of Pediatric Cushing’s Cases
A study published in the journal Clinical Endocrinology finds that up to one-third of pediatric and adolescent patients with Cushing’s Disease do not have their tumors visualized on MRI.
