Specifically, the expression of NF-κB, p-p65 and p52 was predicted to be a poor prognosis factor of DLBCL in some studies [42, 43], as well as the p-IΚBα in ABC-DLBCL [44], but the expression of Rel was reported to be associated with superior clinical outcome [45]. The gene discussed is NFKB1; the disease is aneurysmal bone cyst.
