The study found that patients with DLBCL component ≥ 50% had higher grade 3 ratio (94.3% vs 91.9%, P=0.010), Ki-67 index ≥ 70% ratio (58.5% vs 32.9%, P=0.013) and PET-CT SUVmax ≥ 13 ratio (72.4% vs 46.3%, P=0.030) than patients with DLBCL component<50%. Here, MKI67 is linked to diffuse large B-cell lymphoma.
