Overview
45% of pituitary adenomas are prolactinomas, making it the most common type of all pituitary adenomas.[1] The prevalence of prolactinoma in people less than 20 years old is 10 per 100,000 individuals worldwide. Prolactinoma most commonly affects people between 20 and 50 years old. Prolactinoma is more common in females than males in people between 20 ad 50 years old. Frequency becomes similar after age 50 years.
Epidemiology and Demographics
Prevalence
- Worldwide, the prevalence of sporadic prolactinoma is 6 to 10 per 100,000 persons.[1]
- The prevalence of prolactinoma in people less than 20 years old is 10 per 100,000 individuals worldwide.
- Clinically significant pituitary tumors affect the health of approximately 14 out of 100,000 people in United States.
- Some growth hormone-producing tumors also co-secrete prolactin.
- Microprolactinoma are much more common than macroprolactinoma.
Incidence
- Worldwide, the incidence of sporadic prolactinoma is 0.6 to 1.0 per 100,000 persons per year.[1]
Age
- Age specific distribution of prolactinoma is as follows:[1][2]
- Prolactinoma commonly affects individuals between 20 and 50 years old.
- Prolactinoma occur less commonly in people less than 20 years old with a prevalence of 10 per 100,000 individuals. These tumors account for less than 2% of intracranial tumors in this age group.
Gender
- Women usually have microprolactinoma whereas men usually have macroadenoma.
- Gender-based frequency of prolactinoma depends on the age of the individual:
- Age group: 20 to 50 years
- Women are more commonly affected by prolactinoma than men. The female to male ratio is approximately 10:1.[1]
- The highest prevalance of prolactinoma in women is in age group 20 to 30 years with a female to male ratio of approximately 14:1.
- Age group: >50 years[2]
- Men and women are affected equally after age 50.
- Prevalance of prolactinoma increases with age in men after age 50 and peaks during ages 60 to 70. At this time, the female to male ratio is 1:3.
- Age group: 20 to 50 years
