We aimed to determine the efficacy of Electromotive Drug Administration (EMDA) of mitomycin C (MMC) in BCG unresponsive patients. METHODS: A retrospective review of NMIBC BCG unresponsive patients who received BCG/EMDA-MMC between 2013 and 2017 was performed. Patients had received at least one full regimen of BCG. Progression and overall survival time were calculated using Kaplan-Meier curves. Progression was defined as development of muscle invasive disease, presence of metastasis on imaging or treatment. RESULTS: 26 patients were included. Initial pathology was carcinoma in situ (CIS) in 53.8% (14/26), pT1 in 34.6% (9/26) and pTa HG disease in 11.6% (3/26). 12/26 patients progressed (46.2%). Following BCG/EMDA-MMC treatment, progression-free survival rates were 62.2% (95% CI 43.4-81.0) at 1 year and 53.2% (95% CI 33.4-80.0) at 2 years from the date of induction of BCG/EMDA-MMC, respectively. Side effects included dysuria (19.2%), hematuria (19.2%), and frequency (11.5%). 3 patients were admitted for side effects but managed conservatively. Four patients (15.4%) died of bladder cancer over the course of the study. CONCLUSIONS: BCG/EMDA-MMC represents a viable option in patients with BCG unresponsive NMIBC with over 50% progression-free survival at 2 years. However, the window of curability is narrow with 15% cancer specific mortality in these high-risk patients.
