A 61-year-old man was referred to our hospital with the chief complaint of right leg weakness. Abdominal magnetic resonance imaging (MRI) and computed tomography (CT) demonstrated a ureteral tumor and a neighboring massive retroperitoneal tumor in addition to retroperitoneal lymph node and right renal metastases. The tumor was diagnosed as upper tract urothelial carcinoma (cT4N1M1) by percutaneous tumor biopsy. As the patient achieved a partial response after three courses of combination chemotherapy with gemcitabine and cisplatin, he received total nephroureterectomy and lymph node dissection. The pathology showed no viable cancer cells, demonstrating a pathological complete response. He remains alive after 26 months with no evidence of disease.
一名61岁男性因右腿无力为主诉被转诊至我院。腹部磁共振成像（MRI）和计算机断层扫描（CT）显示除腹膜后淋巴结和右肾转移外，还有输尿管肿瘤及相邻的巨大腹膜后肿瘤。经皮肿瘤活检诊断该肿瘤为上尿路尿路上皮癌（cT4N1M1）。由于患者在接受吉西他滨和顺铂联合化疗三个疗程后获得部分缓解，遂接受了全肾输尿管切除术及淋巴结清扫术。病理检查显示无存活癌细胞，证实为病理完全缓解。他在26个月后仍然存活，无疾病证据。
