Abstract: Diffuse large B-cell lymphoma (DLBCL) is the most common invasive non-Hodgkin lymphoma, which responds well to R-CHOP regimen immunochemotherapy, but 30%-40% of the patients eventually develop relapsed and refractory DLBCL. Therefore, the discovery of new prognostic markers is essential to improve the diagnosis and treatment of DLBCL. Immune escape is an important mechanism for the occurrence and development of DLBCL. Studies have shown that TIM-3, BTLA and LAG-3 are highly expressed in DLBCL, which could inhibit the effective function of immune cells in tumor microenvironment, and promote the immune escape of lymphoma cells. Thus, they promote the occurrence and development of DLBCL and affect the effect of conventional chemotherapy. It is important to explore the effects of the above three inhibitory molecules on DLBCL, and they are expected to become new targets for the treatment of DLBCL.
