Strong evidence supports the tumor immune landscape as a determinant of patient responses to immunotherapy. Readily available therapies, including radiation, are being investigated as modifying agents with immune checkpoint blockade. However, surprisingly little is known regarding radiotherapys impact within the tumor microenvironment and intratumoral T cell repertoires of patients, leaving critical gaps to guided design of clinical protocols. Here, samples from renal cell carcinoma (RCC) patients underwent high-throughput analysis to reveal transcriptional immune activation and increased clonality in irradiated tumors.
