Prevalence and Incidence of Somatostatinoma
Prevalance of Somatostatinoma:
20 known cases in the literature (Ganda, 1997) ... see also overview of Somatostatinoma.
approx 1 in 13,600,000 or 0.00% or 20 people in USA [Source statistic for calcuation: "20 known cases in the literature (Ganda, 1997)" -- see also general information about data sources]
Somatostatinoma: Rare Disease
Somatostatinoma is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Somatostatinoma, or a subtype of Somatostatinoma,
affects less than 200,000 people in the US population.
About prevalence and incidence statistics:
The term 'prevalence' of Somatostatinoma usually refers to the estimated population
of people who are managing Somatostatinoma at any given time.
The term 'incidence' of Somatostatinoma refers to the annual diagnosis rate,
or the number of new cases of Somatostatinoma 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.
