T cell receptor gene recombinations in human tumor specimen exome files: detection of T cell receptor-β VDJ recombinations associates with a favorable oncologic outcome for bladder cancer.

ABSTRACT: Understanding tumor-resident T cells is important for cancer prognosis and treatment options. Conventional, solid tumor specimen exome files can be searched directly for recombined T cell receptor (TcR)-α segments; RNASeq files can include TcR-β VDJ recombinations. To learn whether there are medically relevant uses of exome-based detection of TcR V(D)J recombinations in the tumor microenvironment, we searched cancer genome atlas and Moffitt Cancer Center, tumor specimen exome files for TcR-β, TcR-γ, and TcR-δ recombinations, for bladder and stomach cancer. We found that bladder cancer exomes with productive TcR-β recombinations had a significant association with No Subsequent Tumors and a positive response to drug treatments, with p < 0.004, p < 0.05, and p < 0.004, depending on the sample
