Prevalence and Incidence of Neuroblastoma
Neuroblastoma: Rare Disease
Neuroblastoma is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Neuroblastoma, or a subtype of Neuroblastoma,
affects less than 200,000 people in the US population.
Ophanet, who are a consortium of European partners,
currently defines a condition rare when if affects 1 person per 2,000.
They list Neuroblastoma as a "rare disease".
More information about Neuroblastoma is available from Orphanet
About prevalence and incidence statistics:
The term 'prevalence' of Neuroblastoma usually refers to the estimated population
of people who are managing Neuroblastoma at any given time.
The term 'incidence' of Neuroblastoma refers to the annual diagnosis rate,
or the number of new cases of Neuroblastoma diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
