Shih YH, et al. - Clinical features of lymphoma patients with pre-existing autoimmune diseases were determined via this investigation. Also, the effect of pre-existing autoimmune diseases on progression-free survival (PFS) and overall survival (OS) was assessed. Findings demonstrated that lymphoma patients with autoimmune disorders had outcomes that were comparable to the outcomes of lymphoma patients without autoimmune disorders. Overall, autoimmune diseases are not an obstacle to lymphoma treatment.
