肾癌虽较少见,但死亡率较高。国外平均每年约有14万新增病例,约有5.5万患者死亡[1,2]。肾癌早期无症状,出现症状时,约40％的患者病变局限在肾脏,而60％的患者发生了难以预料的转移[3]。根治性肾切除常用于TNM分期为Ⅰ～Ⅲ期的可切除肿瘤患者的治疗,肾癌患者5年总体生存率为40％～50％。各种辅助治疗在改善生存及减少复发率方面无明显进展,激素治疗及化疗均不能阻止肾癌的临床过
Although rare renal cell carcinoma, but higher mortality. An average of 140,000 new cases are reported abroad each year, leaving 55,000 patients dead [1,2]. Early symptoms of renal cell carcinoma, symptoms, about 40% of the patients with lesions confined to the kidney, and 60% of patients had an unpredictable metastasis [3]. Radical nephrectomy is commonly used in the treatment of patients with resectable tumors with TNM stage Ⅰ-Ⅲ. The 5-year overall survival rate of patients with renal cell carcinoma is 40% -50%. A variety of adjuvant therapy in improving survival and reduce the recurrence rate no significant progress, hormone therapy and chemotherapy can not prevent the clinical renal cell carcinoma
