【摘要】 目的 分析肾细胞癌临床诊治和病理方面的新特点。 方法 回顾性分析我院1991～2000年收治的269例肾细胞癌患者临床资料，随访治疗效果。 结果 肾细胞癌病例就诊年龄平均47.1岁。67.3%(181/269)为体检发现。RobsonⅠ期+Ⅱ期252例，约93.7%(252/269)。肾癌根治术242例，术前病侧肾动脉栓塞57例，与非栓塞组对照:手术时间和术中出血量的差异有显著性(χ 2 值分别为4.3、6，P<0.05)，两组5年和10年生存率差异无显著性。肾癌5年、10年总存活率分别是86.2%(232/269)、60.7%(37/61)。39例囊肿相关性肾细胞癌中16例有肾囊肿病史(平均6.2年)，5年生存率为94.9%(37/39)。 结论 肾细胞癌发病年龄年轻化，大多数为低期意外瘤。囊肿相关性肾细胞癌有特殊临床病理特点。术前肾动脉栓塞不能提高远期生存率，应严格掌握使用指征。迟发性肾细胞癌转移无规律性，术后复查要系统全面。

    【Abstract】 Objective To analyze the new characteristics about diagnosis and therapeutics of renal cell carci-noma(RCC)and to summarize the new clinical experience.Methods The clinical data of269patients with RCC were analyzed from1991to2000in our hospital，and their results were followed up.Results The average age of first hospital-in was47.1years old.67.3%(181/269)was discovered by healthy check-up.242patients suffered radi-cal nephrectomy of which57were given preoperative embolization of renal artery.The difference of operation time and bleeding volume in operation was significant statistically between embolization group and control group.The total sur-vival rate of5and10years was86.2%(232/269)and60.7%(37/61)respectively.39cases of cyst-associated RCC had94.9%(37/39)of survival rate of5years.Conclusion The age of patients with RCC now is younger than ever.The most of them are in early stage clinically.Preoperative embolization could not improve the long-term survival rate ......
