Lymphoma refers to a malignancy of the lymphatic system. The lymphatic system is a network of nodes (knots of tissue) connected by vessels. Together, the lymph nodes drain fluid and waste products from the body. The lymph nodes act as tiny filters, removing foreign organisms and cells.
Lymphocytes, are a type of white blood cell that helps fight infections caused by bacteria, viruses, or fungi. The lymph node function is to prevent infections from entering the bloodstream. When the lymphatic system...
Added text to state that in a study of adolescents with stage III primary mediastinal large B-cell lymphoma treated with FAB/LMB-96 therapy, the 5-year event-free survival (EFS) was 66%, versus 85% for adolescents with nonmediastinal diffuse large B-cell lymphoma (cited Gerrard et al. as reference 24 and level of evidence 2A). Also added text about a single-arm study in adults that showed excellent disease-free survival utilizing the DA-EPOCH-R regimen (dose-adjusted etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and rituximab; usually six cycles) with filgrastim and no radiation therapy. The 5-year EFS was 93% and overall survival (OS) was 97% (cited Dunleavy et al. as reference 25 and level of evidence 2A).
Revised text to state that the genetic hallmark of adult follicular lymphoma, the translocation of t(14;18)(q32;q21) involving BCL2, is typically not detectable in pediatric follicular lymphoma (cited Liu et al. as reference 51). Also added text to state that molecular alterations observed in pediatric follicular lymphoma include translocations of the immunoglobulin locus and IRF4, losses of regions of chromosome 1p, and mutations of TNFSFR14 on chromosome 1p (cited Launay et al. as reference 52).
Revised text to state that pediatric follicular lymphoma predominantly occurs in males, is associated with a high proliferation rate, and is more likely to be localized disease; in contrast, adult follicular lymphoma usually presents as disseminated disease with a relatively low proliferation rate.
Treatment Option Overview
Added text to state that the International Working Group has updated their response criteria for malignant lymphoma to include positron emission tomography, immunohistochemistry, and flow cytometry data.
Added Bakhshi et al. as reference 21.
