BACKGROUND: Devices that increase the penetrance of intravesical chemotherapeutics are emerging as alternatives to classical Bacillus Calmette Guérin (BCG) treatment.
OBJECTIVE: To compare the efficacy of mitomycin C applied with the electromotive drug delivery device (MMC-EMDA) versus BCG in patients with intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) without carcinoma in situ (CIS).
METHODS: Prospective non-randomized study in which 47 patients received MMC-EMDA (40 mg of MMC diluted in 50 mg of distilled water at 20 mA for 30 min. Regimen of 6 weekly and then 6 monthly instillations) and 48 patients received BCG (50 mg of OncoCITE® diluted in 50 ml of normal saline for 60 min. Regimen of 6 weekly instillations and then 3 weekly instillations at months 3, 6 and 12). The primary endpoint was the recurrence-free rate (RFR) at 24 months. Secondary endpoints were time to recurrence and progression-free rate (PFR) at 24 months follow-up.
RESULTS: Baseline patient assessment and mean follow-up time were similar in both groups (MMC-EMDA group: 26.4 months; BCG group: 28.4 months (p = 0.44)). The RFR at 24 months was 80.9% for the MMC-EMDA group and 77.1% for the BCG group (p = 0.969). The mean time to recurrence was 12.5 months in the MMC-EMDA group and 14 months in the BCG group (p = 0.681). At 24 months, PFR was 97.9% in the MMC-EMDA group and 93.8% in the BCG group (p = 0.419).
CONCLUSIONS: No differences were found between MMC-EMDA and BCG treatments in patients with high-risk and intermediate-risk NMIBC without CIS.
