Overview
Epidemiology and Demographics
- Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy in the world.[1]
- NHL ranks as the 7th most common cancer among males and the 6th most common cancer among females.[1]
Incidence
- The incidence/prevalence of Non Hodgkin Lymphoma is approximately 13.2 per 100,000 individuals worldwide.[1]
Case-fatality rate/Mortality rate
- Non Hodgkin Lymphoma is the 6th most common cause of cancer related death in the world.[1]
Age
- Patients of all age groups may develop Non Hodgkin Lymphoma.[2]
- B and T cell lymphoblastic lymphoma/leukemia occurs most frequently in children and adults greater than 65 years of age.
- Burkitt Lymphoma affects individuals between 20–64 years of age.
- Primary mediastinal large B-cell lymphoma has a median age of 35.
Race
- Non Hodgkin Lymphoma usually affects individuals of the Caucasian race.[3]
- In the US, the relative risk (RR) of HIV-associated NHL in African-American is half that of Caucasians (RR 22.3, 95% CI, 17.1–29 vs. RR 46.2, 95% CI, 38.8–55) mainly due to ethnic variations in immune system regulatory genes.[4]
Gender
- Men are more commonly affected by Non Hodgkin Lymphoma than women. The Male to female ratio is approximately 1.5:1 to 3:1.[5][6][7]
Region
- The majority of Non Hodgkin Lymphoma cases are reported in North America, Africa and East Asia.[8]
