肾梭形细胞癌的诊断和治疗(附8例报告)

目的提高肾梭形细胞癌的诊治水平和对此类型肾癌的认识。方法回顾性分析8例肾梭形细胞癌的临床资料,结合文献复习进行讨论。结果8例均行根治性肾切除术,术后病理证实为肾梭形细胞癌;随访6-17个月,7例死于术后肿瘤复发或转移,1例随访9月出现肺转移。结论肾梭形细胞癌是一种高度恶性少见的肾细胞癌,确诊有赖于影像学检查及典型病理表现,治疗以手术为主,预后不良。

The Diagnosis and treatment of spindle renal cell carcinoma(report of 8 cases)

Objective To improve the diagnosis and treatment of renal spindle cell tumors (RSCTs) and the recognition of this subtype of renal cell carcinoma. Methods We compared the clinical data of 8 cases with RSCTs and the literature was reviewed. Results Radical nephrectomy was performed in all these cases. Postoperative pathological findings confirmed the diagnosis of RSCTs. All cases were followed up, ranging from 6 to 17 months. 7 cases died in postoperative relapse or metastasis. 1 case is still alive but has pulmonary metastasis 9 months after radical nephrectomy. Conclusion RSCTs is an infrequent and high-grade malignant tumor; the diagnosis depends on the imaging and pathologic techniques. Surgery is the primary means in treating spindle renal cell carcinoma, and RSCTs has poor prognosis.
