The expression of miRNA-155 was not associated with patients’ age (p=0.682), sex (p=0.902), serum LDH level (p=0.245), serum β2 microglobulin level (p=0.529), clinical stage (p=1.00), age-adjusted IPI score (p=0.338), extranodal involvement (p=0.088), or the response to treatment in DLBCL patients (p=0.800) (Table 2). This evidence concerns the gene HLA-G and diffuse large B-cell lymphoma.
