目的分析无症状与有症状肾癌在临床表现中的差异。方法对肾细胞癌患者根据无症状与有症状两组进行临床分析。结果１１０例肾癌的两组发病年龄相似，平均５２岁。有症状组血尿、腰痛、肿块分别为４６．４％、２７．３％、１７．３％。三联症为４．５％。二联症为２０．０％。无症状组肿瘤大小及分期明显低于有症状组。无症状组１、３、５年生存率分别为９２．０％、６９．２％、６０．０％；有症状组分别为８０．４％、６２．５％、３３．３％。两组有明显差别。结论肾癌典型的临床表现逐渐减少，无症状肾癌发生率上升。目前，无症状肾癌的诊断主要依赖于影像学检查，尤其Ｂ超、ＣＴ等有助于提高检出率。
Objective To analyze the difference of clinical manifestations between asymptomatic and symptomatic renal cancer. Methods The clinical analysis of patients with renal cell carcinoma based on asymptomatic and symptomatic two groups. Results 110 cases of renal cell carcinoma of the two groups of similar age, average 52 years old. The symptoms of hematuria, back pain, mass were 46.4%, 27.3%, 17.3%. Triad is 4.5%. Second-trimester was 20.0%. Asymptomatic group tumor size and stage was significantly lower than the symptomatic group. The 1, 3, 5-year survival rates of the asymptomatic group were 92.0%, 69.2% and 60.0%, respectively; those in the symptomatic group were 80.4%, 62.5% and 33.3%, respectively. There are obvious differences between the two groups. Conclusion The typical clinical manifestations of renal cell carcinoma are gradually reduced, and the incidence of asymptomatic renal cell carcinoma is increased. At present, the diagnosis of asymptomatic renal cancer mainly depends on the imaging examination, especially B-, CT, etc. to help improve the detection rate.
