Overview
Epidemiology and Demographics
Incidence
- The incidence of nasopharyngeal carcinoma is different based on the geographic areas. The incidence in the USA is approximately 0.2 to 0.5 per 100,000 individuals, in Alaska and Greenland is 15 to 20 per 100,000 individuals and the highest incidence is seen in southeast Asia, North Africa, southern China and middle east with the incidence of 80 per 100,000 individuals.[1][2]
- In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
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
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [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
- [Disease name] affects men and women equally.
- [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].
Epidemiology
Age
Patients of all age groups may develop nasopharyngeal carcinoma.
Gender
Nasopharyngeal carcinoma affects men and women equally.
Race
Nasopharyngeal carcinoma usually affects individuals of the Far Eastern (e.g. Chinese) ethnicity.
Demographics
- Nasopharyngeal carcinomas account for approximately 70% of all primary malignancies of the nasopharynx.
- Although it is rare in Western populations, it is one of the most common malignancies in Asia. Nasopharyngeal carcinoma is thought to be very common in Southern China, accounting for approximately 18% of all cancers in China.[3][4][5]
