Abstract
Background: Epstein-Barr virus (EBV) is detected in 40% of
patients with Hodgkin lymphoma (HL). During latency, EBV
induces epigenetic alterations to the host genome and decreases
the expression of pro-apoptotic proteins. The present study
aimed to evaluate the expression levels of mRNA molecules
and the end product of proteins for the JAK/STAT and NF-κB
pathways, and their association with clinicopathological and
prognostic parameters in patients with EBV-positive and -negative classical Hodgkin lymphoma (CHL).
Methods: A prospective cohort study was conducted from 2017
to 2022 at the Faculty of Medicine, Zagazig University Hospital
(Zagazig, Egypt). Biopsy samples of 64 patients with CHL
were divided into EBV-positive and EBV-negative groups. The
expression levels of mRNA molecules (JAK2, STAT1, IRF-1,
PD-L1, IFN-γ, NF-κB, Bcl-xL, COX-2) and the end product of
proteins (PD-L1, Bcl-xL, COX-2) were determined and compared
with clinicopathological and prognostic parameters. Data were
analyzed using the Chi square test and Kaplan-Meier estimate.
Results: EBV-positive CHL patients were significantly
associated with positive expression of mRNAs molecules
(P<0.001) and the end product of proteins (P<0.001) for the
JAK/STAT and NF-κB pathways, B-symptoms (P=0.022),
extra-nodal involvement (P=0.017), and advanced stage of
CHL (P=0.018). These patients were more susceptible to
cancer progression, higher incidence of relapse (P=0.008), poor
disease-free survival rate (P=0.013), poor overall survival rate
(P=0.028), and higher mortality rate (P=0.015).
Conclusion: Through the activation of JAK/STAT and NF-κB
signaling pathways, EBV-positive CHL is associated with poor
clinicopathological parameters, higher incidence of disease
progression, relapse, and poor overall survival.
