Abstract
The incidence and clinical implications of autoimmune diseases (ADs) in patients with non-Hodgkin’s lymphoma(NHL) remain unclear. The aim of this study was to examine the prevalence of ADs in NHL and define the clinical characteristics and prognosis of AD-associated NHL patients. Patients diagnosed with NHL in our institute between 1995 and 2017 were retrospectively reviewed to assess the incidence of ADs. Of 4880 patients with NHL, 140 (2.9%) presented with autoimmunity, with a total of 24 ADs. The most common AD was Sjögren syndrome, followed by autoimmune cytopenia, psoriasis, rheumatoid arthritis, etc. Psoriasis and rheumatoid arthritis were significantly associated with pre-existing ADs, whereas autoimmune cytopenia was significantly associated with secondary AD. Sjögren syndrome was significantly associated with B-cell lymphoma, and systemic vasculitis was significantly associated with T-cell lymphoma. Patients with AD-associated NHL had a high frequency of extranodal involvement(87%), with significant associations between specific extranodal sites of lymphoma and subtypes of ADs. Among patients with available data on pre-treatment peripheral blood Epstein-Barr virus (EBV) DNA(n = 68), elevated EBV-DNA load was observed in a variety of NHL subtypes, including 20% of marginal zone lymphoma and 14.3% of follicular lymphoma patients. In a matched-pair analysis, survival did not differ significantly between NHL patients with and without ADs. However, for NHL patients with pre-existing ADs, a prior history of systemic corticosteroids therapy was significantly associated with worse survival (HR = 7.33, P = 0.006). Taken together, our data suggest that a broad spectrum of ADs is associated with NHL, and AD-associated NHL has distinct features with regard to clinical manifestations and prognosis.
