抄録

A 63-year-old man who presented with asymptomatic gross hematuria was referred to our hospital. Left ureteral tumor (cT3N0M0) was diagnosed and left nephroureterectomy was performed. Pathological examination revealed urothelial carcinoma and small cell carcinoma with local invasion (pT3). The patient was treated with three cycles of adjuvant chemotherapy with gemcitabine and cisplatin. Three months after the chemotherapy, cystoscopy showed an intravesical recurrence of the tumor. Transurethral resection was performed and histopathological examination revealed small cell carcinoma (pT1). We recommended a cystectomy and neoadjuvant chemotherapy with etoposide and carboplatin according to the standard care of small cell carcinoma of bladder. However, the patient refused to undergo cystectomy and desired to preserve his bladder. Therefore, after two cycles of chemotherapy with etoposide and carboplatin, transurethral resection was performed to examine the presence of the residual tumor instead of immediate cystectomy. Because of no residual tumor, another two cycles of chemotherapy were added instead of a cystectomy. There is no evidence of recurrence seven months after the chemotherapy.
