Overview
Epidemiology and Demographics
Incidence
Ovarian sex cord-stromal tumors are very uncommon neoplasms that represent only 7% of all ovarian tumors[1][2]
- The yearly adjusted incidence rate is approximately 2 per 1,000,000 women for SCSTs
Prevalence
- The incidence/prevalence of [disease name] is approximately [number range] per 100,000 individuals worldwide.
- In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
- The prevalence of [disease/malignancy] is estimated to be [number] cases annually.
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
The age at presentation varies depending on the subtypes of sexcord-stromal ovarian tumors:[3]
Fibromas:
- Although they can present at any age, the mean age of occurrence is in the late forties
Thecomas:
- They are more likely to occur in postmenopausal women
Sclerosing stromal tumor(SSTs):
- SSTs are more likely to occur in young women
- Approximately 80% of the reported cases are under 30 years of age
- A few cases have been reported in premenarchal girls, although SSTs most commonly occur after menarche
Steroid cell tumors:
- The average age of presentation is 43 years
Adult and juvenile granulosa cell tumors:
- The incidence of adult granulosa cell tumors peaks in early postmenopausal women
- The juvenile form occurs predominantly in children and young women (<30 years)
Race
- Racial predilection do exist for sexcord-stromal ovarian tumors[2]
- Racial differences in incidence and mortality within the United States are similar to the observed international variation
- Sexcord-stromal ovarian tumors(SCSTs) have more predilection in women of Caucasian background
- Rates are highest among Whites, intermediate for Hispanics, and lowest among Blacks, and Asian people
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
