Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
