[Neoajuvant Chemotherapy with Gemcitabine and Cisplatin Plus S-1 for Primary Female Urethral Adenocarcinoma].

ABSTRACT

A 67-year-old female presented for evaluation of a left inguinal mass. Contrast-enhanced computed tomography revealed a tumor surrounding the urethra. Magnetic resonance imaging showed that the tumor had invaded the bladder neck on the anterior aspect of the urethra. The serum carbohydrate antigen 19-9 level was elevated. The clinical diagnosis was a primary adenocarcinoma of the female urethra (cT4N2M0). The initial treatment consisted of gemcitabine plus cisplatin (GC) and oral fluoropyrimidine (S-1). A total cysto-urethrectomy with anterior vaginal wall resection, pelvic and inguinal lymphadenectomy, and urinary diversion with ileal conduit formation were performed. The final diagnosis was urethral adenocarcinoma (ypT4ypN2, stage IV). Twelve months post-operatively, there was no evidence of recurrence or distant metastases.
