The venous and lymphogenic tumor extension (Robson, Stage III) was assessed in two patient collectives with renal neoplasms: in the first (n = 47), only cavography, in the second (n = 45), only computerized tomography was performed. For both groups there were no false negative diagnoses. False positive readings can occur with CT. Thus, ambiguous findings in CT should be clarified by cavography. CT was superior to cavography regarding the detection of pathologic lymph nodes. However, lymph node enlargement was caused in 10% of these cases by inflammatory hyperplastic reaction without evidence of metastatic tumor spread.
在两个肾肿瘤患者群体中评估了静脉和淋巴源性肿瘤扩展情况（罗布森分期III期）：第一个群体（n = 47）仅进行了腔静脉造影，第二个群体（n = 45）仅进行了计算机断层扫描。两组均未出现假阴性诊断。CT可能会出现假阳性读数。因此，CT检查中不明确的结果应通过腔静脉造影来明确。在检测病理性淋巴结方面，CT优于腔静脉造影。然而，在这些病例中，10%的淋巴结肿大是由炎症性增生反应引起的，无转移性肿瘤扩散的证据。
