Abstract
- The objective response rate (ORR) of tyrosine kinase inhibitors (TKIs) therapy in metastatic renal cell cancer (mRCC) patients was not satisfactory. Effective indicator of mRCC patient selection for TKI therapy is urgently needed. The function of tumor infiltrating B lymphocytes (TIBs) in tumor immune elimination is still unclear. We aim to investigate the prognostic and predictive value of TIBs for TKI therapy in mRCC patients in this study. 108 eligible patients treated with TKI were enrolled in this study. TIBs was estimated by immunohistochemical staining of CD19 in the resected tumor, and its relationship with clinicopathological features, clinical outcomes and CD8+ tumor infiltrating T lymphocytes (CD8+ TILs) were evaluated. Associations between the expression level of CD19 and CD8+ TILs associated cytotoxic effectors were also assessed in public databases. Results showed TIBs positive infiltration predicted better therapeutic response to sunitinib (p = 0.006), longer overall survival (OS) (p
