尿道小細胞癌の1例

Abstract

We report a case of small cell carcinoma of the urethra with inguinal lymph node metastases. A 50- year-old female patient presented with gross hematuria. Cystoscopy and computed tomography (CT) revealed a tumor surrounding the urethra and an inguinal lymphadenopathy. Biopsy of the urethral tumor demonstrated small cell carcinoma. Four courses of chemotherapy with etoposide and cisplatin, followed by 66 Gy of irradiation achieved complete remission. Unfortunately, 14 months later, positroemission-CT scan revealed recurrence of inguinal lymph node metastases. Although seven courses of chemotherapy with nogitecan were carried out, a new metastatic bone tumor developed. Amrubicin was administered as a third-line treatment, but was canceled after one course because of side effects. The patient died at 39 months after diagnosis. Small cell carcinoma of urethra with metastases has extremely poor prognosis, as is demonstrated by this case.
