偶发性肾癌59例临床分析

Clinical analysis of 59 cases of incidental renal carcinoma

目的 探讨偶发性肾癌患者的临床特征、诊治方法和影响预后的因素。方法 对59例偶发性肾癌患者的临床资料进行回顾性分析,并与99例非偶发性肾癌患者的临床资料进行比较。结果 与非偶发性肾癌相比,偶发性肾癌均为Ⅰ、Ⅱ期肿瘤,病理分期低(P< 0. 01 );平均肿瘤直径( 4. 2 cm)小(P<0. 01), 3年及5年生存率(86. 4%, 71. 2% )高(P<0. 01)。结论 偶发性肾癌是肾癌未出现临床表现的一个发展阶段,并非肾癌的另一类型。B超和CT是偶发性肾癌的主要诊断方法。病理分期低、瘤体小、早期发现和尽早行根治性肾切除术是偶发性肾癌患者预后较好的重要因素。

Objective To study the characteristics,diagnosis and treatment and prognosis of incidental renal carcinoma.Methods Clinical data of 59 cases of incidental renal carcinoma were retrospectively analyzed,and compared with those of 99 cases of non-incidental renal carcinoma.Results Compared to the non-incidental renal carcinoma,incidental renal carcinoma was in stage I and II (P<0.01) and their diameters were smaller (4.2 cm) (P<0.01),3- to 5-year survival rates of patients were higher than those of non-incidental renal carcinoma (P<0.01).Conclusion Incidental renal carcinoma is not another type of renal carcinoma,but a developing stage of renal carcinoma.Ultrasonography and CT are important to the diagnosis of incidental renal carcinoma.Low pathological staging,small size,early diagnosis and radical nephrectomy are the most important factors of better prognosis of incidental renal carcinoma.
