CD274 and neoplasm: To generate their computer model, researchers analyzed data (measured mutations and gene expression in the tumor and T cell receptor (TCR) sequences in the tumor and peripheral blood in urothelial cancers treated with anti-PD-L1) from 21 patients with bladder cancer from a clinical trial dataset of urothelial cancers from Snyder et al. [61] with a uniquely rich data set that captured information about tumor cells, immune cells, and patient clinical and outcome data.
