For many neurosurgeons, years of training and technical refinement culminate in safely removing a patient’s brain tumor. We dedicate our careers to shepherding people past this inflection point, but the patient journey does not end there. For those with malignant tumors, our surgical heroics are quickly unraveled by tumor recurrence. Theoretically, adjuvant medical therapy should firewall patients against this reality; however, as we all know, no drug today provides much security to brain tumor patients. Our specialty is uniquely positioned to do something about this. Drug development is no longer the sole domain of oncologists, and some of the most impactful drug studies live in our operating rooms.
