ABSTRACT
OBJECTIVE:
To evaluate the effectiveness of electro-mediated drug administration of mitomycin C (EMDA/MMC) after transurethral resection of the bladder tumour (TURBT) in preventing non-muscle-invasive bladder cancer (NMIBC) recurrence and progression and to explore clinical and demographic factors associated with treatment response. PATIENTS ANDMETHODS:
Between April 2016 and August 2019, 112 patients diagnosed with intermediate- or high-risk NMIBC underwent a TURBT followed by an EMDA/MMC treatment. The percentage of treatment responders and progression-free survivors at 3 and 6 months were evaluated.RESULTS:
Follow-up data were available for 101 patients (90%) at 3 months and 92 (82%) at 6 months. Response rates to EMDA/MMC treatment were 85% at 3 months and 75% at 6 months, and progression-free rates were 94% and 90%, respectively. No statistically significant differences were seen between intermediate- and high-risk patients. A higher risk of tumour recurrence and progression was associated with previous Bacillus Calmette-Guérin (BCG) failure. According to the Clavien-Dindo classification, only low-grade complications were observed.CONCLUSIONS:
EMDA/MMC after TURBT was associated with high response and progression-free rates at 3 and 6 months, with only low-grade adverse events. These results confirm the efficacy and safety of EMDA/MMC as a therapeutic option for both intermediate- and high-risk patients. However, patients with BCG failure responded poorly to EMDA/MMC.Abbreviations ACCI age-adjusted Charlson Comorbidity Index; CHT chemohyperthermia; CIS carcinoma in situ; EMDA electro-mediated drug administration; EORTC European Organisation for Research and Treatment of Cancer; IQR interquartile range; (N)MIBC (non-)muscle-invasive bladder cancer; MMC mitomycin C; OR, odds ratio; TURBT transurethral resection of the bladder tumour.
