Refractory and Relapse Predictive Biomarkers in Hodgkin Lymphoma and Potential Directed-Therapy Targets (original) (raw)

Blood, 2018

Abstract

Despite 90% stage I Hodgkin Lymphoma (HL) patients can respond to current systemic therapy, this drops to 60%, when diagnosed in advanced stages. Nevertheless and independently of the lymphoma stage, the real challenge when treating these patients, is the refractory and relapsed disease. There is no molecular biomarker to identify patients that would be non-responsive to conventional treatment or that would relapse. Furthermore, rescue chemotherapy schemes for refractory and relapsed patients, associate with acute and late toxicity high risk. This highlights the need to deeper understand the HL molecular biology and the screening for predictive biomarkers as well as potential therapeutic directed-targets. We have previously reported that HL relies on the alternative NFkB pathway, mediated by RelB and NIK, to survive. Depletion of either RelB or NIK by shRNAs or pharmacological NIK inhibitors induce HL cell death. ChIP-Seq analysis uncovered RelB target genes showing RelB bound to BC...
