As the Director of the Brain Tumor Treatment and Research Center at the University of Maryland (UMd), I provide leadership and surgical care within a multidisciplinary team of radiologists, medical oncologists, radiation oncologists, neurosurgeons, and pathologists, treating brain cancer patients. This clinical role enables me to facilitate the cross-disciplinary group of engineers, cancer biologists, and clinician-scientists within the Translational Therapeutics Research Group (TTRG) to address key challenges in counteracting the patho-biology and improving the treatment of brain cancer. Much of this work is centered on the concept of using the operating room as a portal for discovery and opportunity to improve our understanding of and therapeutic delivery for brain cancer. I study and utilize advanced brain tumor models, including genetically-engineered and patient-derived versions directly from the operating room where the tumor tissue is rapidly passaged in vivo to avoid ischemia and biological transformation during extended manipulations or culturing conditions. We have developed a nestin-TV-A transgenic rat model to enhance investigations into the molecular and cellular mechanisms of the glioblastoma margin (GBm) and enable surgery-, local delivery-, focused ultrasound-, and targeted radiation-based studies.
A long-standing goal in treating patients with glioblastoma (GB), the most common and deadly primary brain cancer, is linking tumor specific features with effective anti-tumor therapies to generate long-term treatment responses. Ibelieve that following the principles of (1) maximal, safe tumor removal, (2) use of intra-operative access to better understand the disease and deliver therapies, and (3) targeting therapeutics to residual/unresectable invading cancer elements, we will turn GB from a uniformly fatal cancer into a chronic disease with the potential for cure.
