Primary small cell carcinoma of the ureter with hydronephrosis: A case report

Publication date: Available online 14 December 2019Source: Urology Case ReportsAuthor(s): Ryuta Sato, Takahiro Ishikawa, Masaharu Imagawa, Hirotoshi Yonemasu, Takahiro Narimatsu, Kan MurakamiAbstractSmall cell carcinoma in the ureter is extremely rare, with few cases reported in the literature. The current report describes the case of a 63-year-old man who presented with right-side back pain. A mass was identified in the right ureter. A nephroureterectomy was performed. Subsequent microscopic examination revealed that the mass comprised a monotonous population of small cells and that the carcinoma cells were positive for cluster of AE1/AE3 and synaptophysin. The tumor was diagnosed as a ureteral small cell carcinoma. Adjuvant chemotherapy was administered with 80 mg/m2 intravenous cisplatin on day 1 and 100 mg/m2 etoposide on days 1–3, every 21 days for 2 cycles. The patient has remained disease-free 6 months after surgery.

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]
