Abstract
- BACKGROUND
The Hematopathology Study Group of the Korean Society of Pathologists conducted a nation-wide retrospective analysis of Korean pediatric lymphoma, to provide pathologic data on pediatric/adolescent lymphoma subtypes and features.
METHODS
All lymphoma cases of all age groups were collected during a recent 2 year-period (2005-2006) from 32 institutes in Korea. Among 3,686 lymphoma patients, 142 who were age 18 or less were classified according to the World Health Organization (WHO) classification.
RESULTS
Among 142 pediatric/adolescent lymphoma patients, Hodgkin lymphoma accounted for 21 (14.8%) and non-Hodgkin lymphoma (NHL) for 121 (85.2%). Hodgkin lymphoma appears to be more common in the pediatric/adolescent age group than in the all-ages group (14.8% vs 4.4%). T- and natural killer cell-NHL was more common in the pediatric/adolescent age group than in the all ages group (46.3% vs 22%). The majority of Korean pediatric/adolescent NHL cases was composed of Burkitt lymphoma, T- or B-lymphoblastic lymphoma, anaplastic large-cell lymphoma, and diffuse large B-cell lymphoma. For lymphoma patients under the age of 6 years, most had B-lymphoblastic or Burkitt lymphoma, which commonly presented at extranodal sites.
CONCLUSIONS
The distribution of lymphoma subtypes in the pediatric/adolescent age group is quite different from the distribution of adults, but it was quite similar to distribution in Western countries.
