Proud and excited of the work that Alexander Himstead is doing with our team by characterizing and deciphering the heterogeneity of aggressive non-functional Pituitary Neuroendocrine tumors and laying down the foundation for exciting future scientific work at UC Irvine Neurosurgery 🧪 🧫 🧬 🔬

Non-functioning Pit-NETs are among the most common pituitary tumors we operate on due to mass effect. Our group is committed to characterizing their heterogeneity and patterns of invasion and growth using WHO transcription factor profiling to determine the underlying mechanisms

In a recent study (May 2025) published in Nature Genetics, Nomura et al.(Roel Verhaak , Lavarone, Mario Suva , Tirosh Lab labs) leveraged single-nucleus RNA sequencing and bulk tumor DNA sequencing to unveil new dimensions of GBM complexity. The team discovered three previously

It’s my favorite time of the year when we celebrate the outgoing and incoming future of neurosurgery. Congratulations to our graduating Chiefs, Jordan and Alvin, and our graduating fellows Tigran and Nolan. You know you are doing something right as a program when every year you

Higher volume helps. 📊 Our new analysis of ~15,000 patients undergoing endoscopic transsphenoidal surgery (ETSS) for pituitary tumors published in Journal of Neurosurgery shows: 🏥 Higher institutional volume --> lower risk •Major complications steadily drop as case volume rises until ~58

Beautiful work by DrJFM - Juan C. Fernandez-Miranda MD - group showing the variations of the CCL and patterns of pituitary tumor invasion! This knowledge is key to deliver outcomes like this in a recent patient who presented with 3rd and 6th nerve palsies. Resecting the medial wall and decompressing
