ERCC2 and urinary bladder carcinoma: Our results indicating the association of some polymorphic variants of ERCC6/CSB and ERCC2/XPD genes with advanced bladder cancer (T ≥ 2 as compared to Ta/T1 tumors or T ≥ 2 high as opposed to T ≥ 2 low grade carcinomas) fit into an overall picture, but the problem needs to be further explored to confirm some regularities arising from our own and literature data.
