Lymphoma in the setting of autoimmune diseases: A review of association and mechanisms


Khanmohammadi S, et al. Crit Rev Oncol Hematol 2020 - Review.


Autoimmune disorders are a spectrum of diseases caused by impaired self-tolerance of the immune system. Previous studies underscored the association between autoimmune disorders and lymphomas. However, only a few papers studied the exact mechanisms of this association. The effect of IL-2, IL-5, IL-6, IL-10 and TNF-α, contribution of NOTCH, FAS and MHC receptor families, the interplay of various immune cells, and the relation of immunosuppressive agents and development of autoimmune disorders are

the proposed mechanisms for this association. Each individual autoimmune disorder associates with particular types of lymphomas and their common pathways are not necessarily similar to other pairs of autoimmune disorder-lymphomas. Thus, the lymphomas susceptibility in various autoimmune disorders could not be investigated through a single pathway. In this review, we demonstrate the association between each pair of autoimmune disorder-lymphoma and the underlying pathways. By clarifying these associations, follow-up plans could be made leading to early diagnosis of lymphomas.
