IL10 and diffuse large B-cell lymphoma: Cox regression analysis for overall survival revealed that high expression of VEGF, high level of serum IL-8, serum IL-10, and RIP2, Ann Arbor Stage (III-IV), number of extranodal sites (>1), serum LDH level (≥245 U/L), IPI scores (3–5), ECOG scores (≥2), and bone marrow involvement were independent risk factors for the prognosis of DLBCL patients (all P < 0.05).
