A Natural History Study of Children and Adults With Olfactory Neuroblastoma
What this study is about
Background: Olfactory neuroblastoma (ONB) is a rare cancer. It grows from tissue in the upper part of the nose cavity, related to the sense of smell and can affect a person s sense of smell. Researchers want to better understand the health problems of people with ONB. This may help them design better treatment and supportive care studies.

Background: Olfactory neuroblastoma (ONB) is a rare cancer. It grows from tissue in the upper part of the nose cavity, related to the sense of smell and can affect a person s sense of smell. Researchers want to better understand the health problems of people with ONB. This may help them design better treatment and supportive care studies. Objective: To better understand ONB-the course of the disease, tumor characteristics, response to treatments, and management of the treatment. Eligibility: People ages 3 years and older who have ONB. They must enroll in NIH studies #19-C-0016 and #18-DC-0051. Design: Participants will be screened with a medical history and medical record review. Participants do not have to visit NIH. Participants will give a blood sample. They will complete surveys to assess their emotional and physical wellbeing and needs. Leftover tissue from biopsies and surgeries will be collected. Participants will take smell tests. They will smell items and answer questions about them. Participants may take taste tests. They will get plastic taste strips that they will move around their mouth to determine the taste. Participants may have a physical exam. Their performance status may be assessed. Participants may give blood, saliva, urine, and nasal secretion samples. Participants may have computed tomography and/or magnetic resonance imaging scans. Participants may have one or more tumor biopsies. Participants will talk to the research team about the results of their medical record/tests evaluation. The team will recommend how to best manage and treat their disease. Participants may give samples and complete surveys every 12 months. Their medical records will be reviewed every year. They will be monitored for the rest of their life.
Primary outcome measures
Characterize the natural history of ONB
Time frame: duration of study
To characterize the natural history of ONB including clinical presentation, family history, patterns of disease progression, response to current treatment methods, disease recurrence, and overall survival.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
