Overview
B-cell lymphomas include both Hodgkin's lymphomas and most of the Non-Hodgkin lymphomas. The incidence of non-Hodgkin lymphoma is approximately 18.6 per 100,000 individuals worldwide. The incidence of Hodgkin's lymphoma is approximately 2-3 per 100,000 individuals in populations of European ancestry. In the year 2018, the mortality rate of non-Hodgkin lymphoma is approximately 5.1/100,000. In the year 2017, the mortality rate of Hodgkin's lymphoma is approximately 0.41/100,000.
Epidemiology and Demographics
Incidence
The incidence of non-Hodgkin lymphoma is approximately 18.6 per 100,000 individuals worldwide.[1] The incidence of Hodgkin's lymphoma is approximately 2-3 per 100,000 individuals in populations of European ancestry.[2]
Case-fatality rate/Mortality rate
In the year 2018, the mortality rate of non-Hodgkin lymphoma is approximately 5.1/100,000.[1] In the year 2017, the mortality rate of Hodgkin's lymphoma is approximately 0.41/100,000.[3]
Age
Non-Hodgkin lymphoma (NHL) commonly affects individuals older than 65 years of age. However, some subtypes of NHL (i.e., Burkitt lymphoma) show a bimodal age distribution. Hodgkin's lymphoma has a bimodal age distribution with the highest incidence in patients (20-39) years of age and older than 60 years of age.[3]
Race
In the US, Non-Hodgkin lymphoma (NHL) usually affects individuals of the white and non-Hispanic races. Asian/Pacific Islander, American Indian and black individuals are less likely to develop NHL.[1]. Hodgkin's lymphoma shows age-specific racial disparities. In patients aged <65 years, individuals of the white race have the highest incidence of Hodgkin's lymphoma. On the other hand, in patients over 65 years old, individuals of Hispanics have the highest incidence of Hodgkin's lymphoma. Regardless of the age, Asian/Pacific Islanders (A/PI) are less likely to develop Hodgkin's lymphoma.[4]
Gender
Men are more commonly affected by Non-Hodgkin lymphoma (NHL) than women. The male to female ratio is approximately 2 to 1, however, it's known that the male to female ratio is up to 4 in certain subtypes of NHL[5][1]. Men are more commonly affected by Hodgkin's lymphoma than women. The male to female ratio is approximately 3 to 2.3, however, it's known that the male to female ratio varies depending on the age. In children aged 15 to 19 year, females are more commonly affected with Hodgkin's lymphoma than males with the M/F ratio of approximately 0.8. [6][3]
Region
The majority of endemic Burkitt Lymphoma, a subtype of NHL, cases are reported in subequatorial Africa.[1]. Countries with the highest incidence (age-standardized) of Hodgkin's lymphoma include Lebanon, Greece, and Montenegro.[3]
