A similar analysis was applied to other cancer types in TCGA cohort, which revealed that the survival rate of patients with bladder cancer (BLCA, bladder urothelial carcinoma), head and neck cancer (HNSC, head and neck squamous cell carcinoma), sarcoma (SARC, sarcoma), and uterine cancer (UCEC, uterine corpus endometrial carcinoma) was associated with low TOX expression level in the TI T cells (Additional file 2: Figure S5). This evidence concerns the gene TOX and urinary bladder carcinoma.
