[A case report of a young patient with invasive bladder cancer]

A 29-year-old male with bladder cancer was referred to our hospital. Histological examination of transurethral biopsy showed transitional cell carcinoma with invasion into prostate (T4aN0M0, grade 3). Nerve-sparing radical cystectomy with ileal neobladder reconstruction was performed after 3 courses of neoadjuvant chemotherapy with Methotrexate, Epirubicin and Cisplatin. Continence and erectile function were preserved and no recurrence has been observed for 18 months after the operation. This is the sixth case of an invasive bladder cancer in Japanese patients under 30 years old.
