The aim of this study is to evaluate the effectiveness and safety of neoadjuvant intravesical mitomycin-C instillation in non-muscle invasive bladder cancer patients

Study Design: Intervention Model: Single Group Assignment Masking: Open Label

Primary Outcome Measures:

Recurrence-free survival in neoadjuvant intravesical mitomycin-C 40mg/20ml instillation group and control group.

Secondary Outcome Measures:

Progression-free survival in neoadjuvant intravesical mitomycin-C 40mg/20ml instillation group and control group.

Time to recurrence in neoadjuvant intravesical mitomycin-C 40mg/20ml instillation group and control group.

Change of tumor size after neoadjuvant intravesical mitomycin-C 40mg/20ml instillation.

Safety of neoadjuvant intravesical mitomycin-C 40mg/20ml instillation.
