【摘要】 目的　探讨偶发性肾癌的临床特征、诊治方法和影响预后的因素。方法　回顾性分析 2 4年来收治的 93例偶发性肾癌患者的临床资料 ,并与 176例同期治疗的非偶发性肾癌进行对比。结果　偶发性肾癌组和非偶发肾癌组在发病年龄、性别、单双侧和病理类型等方面差异无显著性。偶发性肾癌的病理分期明显低于非偶发性肾癌 (P <0 0 5 ) ,术后 3年 (83 6 % )和 5年 (6 8 6 % )生存率高于非偶发性肾癌 (P <0 0 5 )。结论　偶发性肾癌是肾癌未出现临床表现的一发展阶段 ,并非肾癌的另一类型。B超和CT是发现偶发性肾癌的主要诊断方法。此类型的病理分期低、瘤体小 ,早期发现和尽早根治性肾切除术是偶发性肾癌预后较好的重要因素。更多还原

【Abstract】 Objective To study the characteristics, diagnosis, treatment and prognosis of incidental renal cell carcinoma(RCC). Methods Ninety-three cases of incidental RCC treated in the last 24 years were analyzed retrospectively and compared with 176 cases of non-incidental RCC. Results The age, sex and locatiom were not significantly different between incidental RCC and non-incidental RCC. The stage was lower in incidental RCC(P<0.05).Ultrasonogrphy and CT significantly improved the detection rate of incidental RCC.Surgery was more effective for incidental RCC than for non-incidental RCC. The 3-and 5-year cancer specific survival rates in patients with incidental RCC were higher than those of non-incidental RCC(P<0.05).Conclusion Incidental RCC is not separate type of RCC,but is a developing stage of RCC without appearance of symptoms. Ultrasonogrphy and CT are important for diagnosis of incidental RCC.The pathological stage,is usually low and the size is small. Early diagnosis and radical nephrectomy are indicated for better prognosis of incidental RCC.更多还原
