CXCL9 and diffuse large B-cell lymphoma: Kaplan–Meier curves and logarithmic rank tests showed that increased mRNA levels of CXCL9-14 and decreased CXCL4 and CXCL7-8 mRNA levels were not significantly associated with overall survival (OS) or disease-free survival (DFS) in all patients with DLBCL (P > 0.05).
