Analysis of NF-κB Pathway Proteins in Pediatric Hodgkin Lymphoma: Correlations with EBV Status and Clinical Outcome-A Children's Oncology Group Study.

ABSTRACT: Constitutively active nuclear factor-κB (NF-κB) is integral to the survival of Hodgkin/Reed-Sternberg cells (H/RS) in Hodgkin Lymphoma (HL). To investigate NF-κB pathway proteins in pediatric HL, we utilized a tissue microarray compiled from 102 children enrolled in the Children's Oncology Group intermediate-risk clinical trial AHOD0031 (56 male, 78 Caucasian, median age 15y (range 1-20y), 85 nodular sclerosing subtype, 23 Epstein Barr virus (EBV) positive, 24 refractory/relapsed disease). We examined the intensity, localization, and pathway correlations of NF-κB pathway proteins (Rel-A/p65, Rel-B, c-Rel, NF-κB1, NF-κB2, IκB-α, IKK-α, IKK-β, IKK-γ/NEMO, NIK, A20), as well as their associations with EBV status and clinical outcome. NF-κB pathway proteins were overexpressed in pediatric HL p
