Overview
Epidemiology and Demographics
Incidence
- In USA the age-adjusted incidence of MOGCTs is 0.41 per 100,000 women.[1]
- These tumors are less common than ovarian epithelial tumors.
Mature teratoma
- The incidence of mature/benign teratoma is between 1.2 to 14.2 cases per 100,000 individuals worldwide.[2]
- The germ cell tumors of the ovary consist approximately one-fourth of ovarian neoplasms and a great majority of them are benign.
Dysgerminoma
- Age-adjusted incidence of this tumor is 0.109 per 100,000 women-year.[3]
- The incidence is greater in those with partial or complete gonadal dysgenesis.[4]
Prevalence
Mature teratoma
- Mature teratoma is the most common ovarian germ cell tumor tumor and accounts for 95% of ovarian teratomas.[5]
- 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.
Dysgerminoma
- Dysgerminoma is the second most common ovarian germ cell tumor.[5]
- This tumor accounts for less than 1% of all ovarian cancers.[6]
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
Mature teratoma
- Patients of all age groups may develop mature teratoma. However, they tend to present between 20 to 30 years of age at a greater extent.[7]
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
Immature teratoma
- Immature teratoma tends to affect younger patient than mature teratomas (usually the first 2 decades of life).[8]
Dysgerminoma
- Dysgerminoma commonly affects individuals younger than 30 years of age in 85% of cases.[6]
- The median age at the time of diagnosis is approximately 19 to 23 years, although it may happen at any age.[9]
- The tumor is uncommon prepubertal or postmenopausal.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Race
- There is no racial predilection to [disease name].
- [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].
Gender
- Seminoma is the male counterpart of dysgerminoma in women.[6]
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
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].
- Germ cell tumors of the ovary account for a greater proportion of ovarian tumors in the Asia and Africa.[3]
