Meanwhile, although no somatic mutations in the AR gene were found in 99 cases of bladder cancer [54], a molecular profiling data search [55,56] identified them in up to 4% (2 of 50) of urothelial carcinomas of the bladder as well as in 6.1% (2 of 33) of plasmacytoid urothelial carcinomas. Here, AR is linked to urinary bladder carcinoma.
