title: [Intravesical Electromotive Drug Administration®(EMDA)with Mitomycin-C for non-muscle invasive bladder cancer].
abstract: Electromotive Drug Administration® (EMDA) offers a means of controlling and enhancing the tissue transport of certain drugs, when applied to a surface epithelium, where they have a local therapeutic effect, in order to increase their efficacy. One application option is the treatment of non-muscle invasive bladder cancer with intravesical mitomycin-C (MMC). Laboratory studies demonstrated that EMDA/MMC can reduce the variability and enhance the drug administration rate into all layers of the bladder wall, and that the applied electric current causes no histological damage to tissue and no chemical modification of MMC. A prospective randomized study, performed in patients with in situ carcinoma, validated the prediction that electromotive enhancement of MMC delivery would provide results superior to those achieved using passive MMC transport. A further randomized study in patients with pT1 bladder cancer demonstrated that a regimen combining intravesical BCG and EMDA/MMC increased the disease-free interval and reduced the recurrence rate, as well as the disease progression and mortality rate if compared with BCG alone. The possibility that BCG may enhance the efficacy of MMC against high-grade pT1 transitional cell carcinoma and in situ carcinoma represents an important new therapeutic perspective in the high-risk non-muscle invasive bladder cancer.
