We reviewed the manner of presentation and tumor stage in 56 consecutive patients with renal cell carcinoma treated surgically between 1961 and 1973 (group 1) and compared them to 46 patients treated similarly between 1980 and 1984 (group 2). In group 1, 7 cases (13 per cent) were discovered incidentally compared to 22 cases (48 per cent) in group 2. The tumor stage was lower in the incidentally discovered cases than in cases when the diagnosis was suspected. The 5-year survival rates of the incidental cases in group 1 tended to be better. Routine use of excretory urography, computerized tomography, ultrasound, bone scans and other effective diagnostic studies has led to earlier diagnosis, lower stage and possibly better survival in incidentally found cases of renal cell carcinoma than in cases when the diagnosis was suspected.
我们回顾了1961年至1973年间接受手术治疗的56例连续性肾细胞癌患者的临床表现和肿瘤分期（第1组），并将其与1980年至1984年间接受类似治疗的46例患者（第2组）进行比较。在第1组中，7例（13%）为偶然发现，而在第2组中为22例（48%）。偶然发现病例的肿瘤分期低于疑似诊断病例。第1组中偶然发现病例的5年生存率往往更好。排泄性尿路造影、计算机断层扫描、超声、骨扫描及其他有效诊断检查的常规应用，使得偶然发现的肾细胞癌病例比疑似诊断病例能更早诊断、分期更低，可能生存率也更高。
