NCI Definition: A rare neuroectodermal tumor originating from olfactory receptor cells in the nasal cavity or paranasal sinuses. Microscopically, it is characterized by neuroblastic differentiation with occasional formation of rosettes. If the tumor is not resected at an early stage, the prognosis is usually poor. 
There are 3 clinical trials for olfactory neuroblastoma, of which 3 are open and 0 are completed or closed. Of the trials that contain olfactory neuroblastoma as an inclusion criterion, 3 are phase 2 (3 open).
Cisplatin, etoposide, and ifosfamide are the most common interventions in olfactory neuroblastoma clinical trials.
