We herein report a case involving a 59-year-old man with right lung and mediastinal lymph node metastases from renal cell carcinoma. After cytoreductive nephrectomy without neoadjuvant therapy, he achieved spontaneous regression. The regression was maintained 3 years after the operation. We immunohistochemically examined the surgical specimens and considered the possible mechanism underlying this phenomenon.
我们在此报告一例涉及一名59岁男性的病例，该患者患有肾细胞癌伴右肺和纵隔淋巴结转移。在未进行新辅助治疗的情况下进行了减瘤性肾切除术后，他实现了自发缓解。术后3年缓解状态持续存在。我们对手术标本进行了免疫组化检查，并探讨了这一现象背后可能的机制。
