Thirteen patients with renal carcinoma, primarily not operated upon, were re-evaluated 1 to 71 months after the first nephroangiography. Tumour progression could be demonstrated in 7 cases with a maximum linear diametric growth rate of 0.5 cm/2.5 months. The reasons for absence of growth in the remainder are not apparent, but probably related to the state of immunologic defense mechanism of the host.
13例主要未接受手术治疗的肾癌患者在首次肾血管造影后1至71个月接受了重新评估。7例患者出现肿瘤进展，最大线性直径生长率为0.5厘米/2.5个月。其余患者无生长的原因尚不明确，但可能与宿主免疫防御机制的状态有关。
