摘要
Objective: To investigate the expression levels of programmed death protein 1 (PD-1)、T cell immunoglobulin domain and mucin domain 3(TIM-3)、lymphocyte activating gene 3 (LAG-3) and B and T lymphocyte attenuator (BTLA) in Diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS) and their effects on prognosis. Methods: The paraffin specimens of 30 patients with DLBCL, NOS newly diagnosed in People's Hospital of Zhengzhou University were stained with immunohistochemistry. The effects of single positive and co-expression of the above molecules on progression-free survival (PFS) phase and overall survival (OS) phase were analyzed. Results: There was no significant difference in prognosis between PD-1, TIM-3, LAG3, BTLA single positive group and single negative group. The median PFS phase of PD-1 and TIM-3 co-expression group and TIM3 and BTLA co-expression group were 26 and 24 months respectively, which were both lower than the 54 months (P=0.021) and 47 months (P=0.037) in non-co-expression group. The median PFS phase and OS phase of PD-1, TIM-3 and LAG-3 co-expression group were 17 and 25 months respectively, which were significantly lower than the 41 months (P=0.024) and 60 months (P=0.015) of non-co-expression group. The median PFS phase and OS phase of PD-1, TIM-3, LAG-3 and BTLA co-expression group were 18 and 26 months respectively, which were significantly lower than the 40 months (P=0.038) and 57 months (P=0.041) of non-co-expression group. Conclusions: In patients with DLBCL, NOS, those with PD-1 and TIM-3 co-expression as well as those with TIM-3 and BTLA co-expression have poor PFS phase. Patients with PD-1, TIM-3 and LAG-3 co-expression and patients with PD-1, TIM-3, LAG-3 and BTLA co-expression have poor PFS and OS phase.
