PTCD1 and bladder transitional cell carcinoma: The features of BLCA patients were available in Table 1, and we found that the expression of PTCD1 was correlated with pathologic stage (P=0.001), N stage (P=0.031), and survival status (P=0.007) but was not associated with age (P=0.626), sex (P=0.851), grade (P=0.057), T stage (P=0.193), and M stage (P=0.648).
