KRAS and diffuse large B-cell lymphoma: Reiser et al. investigated CD30 expression in HCV-infected liver samples using immunohistochemical techniques with positive CD30 expression found in 20 of 37 samples (54.05%) [26]. In this study, DLBCL with positive HCV NS3 expression was found in 30 samples that expressed CD30 at cut-offs of >0% and >20% in 8 (26.7%) and 3 (10.0%) samples, respectively, although these results are not statistically significant.
