Olfactory neruoblastoma is a rare cancer that begins to grow in the nerves and tissues behind the nose. It may develop in the empty space behind the nose or upward toward the bone located between the eyes.
Olfactory neruoblastoma has an influence on the patients’ sense of smell and the function of the nose.
The other name of olfactory neruoblastoma is esthesioneuroblastoma.
Cause & Risk Factor
The exact causes of olfactory neruoblastoma are still unknown. The medical experts believe that the olfactory epithelium is the most conjectured place where it is formed.
The factors that may contribute to the development of the tumor include
The typical symptoms of olfactory neruoblastoma include:
- Chronic congestion on one side of the nose
- Loss of smell
- Sinus infections
Also, there are some additional symptoms when the tumor becomes larger.
- Facial swelling
- Neurologic symptoms
- Oral and/or vision problems
Physical exams and imaging tests are needed in the diagnosis. Because olfactory neruoblastoma is a rare cancer, the clinician will need to distinguish it from other cancer by a lot of tests.
At first, a thorough physical examination of the patient’s eyes, throat and nose will be conducted to make sure if there are any obvious signs.
The doctor will insert endoscope into the mouth or the nose of the patient.
This helps the doctor to diagnose the cancer at early stage.
CT scan and MRI scans
The typical treatment for olfactory neruoblastoma is a combination of
- radiation therapy,
- and surgery.
In most cases, surgery is the first choice.
Survival rates are used to know the life expectancy of a certain type of cancer. Usually, a 5-year survival rate is adopted. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed.
For olfactory neruoblastoma, there are three different groups of survival rates.
The percentage of these patients who have 5-year survival rate is higher than 95%.
The percentage of these patients who have 5-year survival rate is between 90% and 95%.
The percentage of the last group of patients who have 5-year survival rate is between 40% and 50%.
