A Natural History Study of Children and Adults With Olfactory Neuroblastoma

ClinicalTrials.govApr 29, 2026

Summary

This National Institutes of Health (NIH) natural history study aims to characterize olfactory neuroblastoma (ONB), a rare cancer arising from olfactory tissue in the nasal cavity. The observational study will collect longitudinal data on disease course, tumor characteristics, treatment responses, and patient-reported outcomes including smell and taste function. Participants ages 3 and older will be monitored throughout their lifetime with periodic surveys, medical record reviews, and optional biological sample collection.

Plain Language Summary

Scientists at the NIH are studying a rare type of cancer that grows in the upper part of the nose and can affect the sense of smell. Because this cancer is so uncommon, doctors don't know as much about it as they'd like. By following patients over many years and collecting information about their disease, treatments, and quality of life, researchers hope to learn enough to design better treatments in the future.

Key Implications

  • This study may improve understanding of how olfactory neuroblastoma behaves over time, which could eventually inform treatment approaches for this rare cancer
  • Patients with ONB may benefit from expert evaluation and management recommendations from the NIH team as part of study participation
  • The comprehensive data collection including smell and taste assessments may help identify supportive care needs specific to ONB patients
  • Because this is observational research, it will not directly test new treatments but could generate hypotheses for future therapeutic trials
