手术治疗肾癌病人根治性肾切除后存活率与单纯性肾切除后相比无显著差异,但因为45％的病例手术时肾周组织已有转移,根治性肾切除术较为合理。5年存活率:Ⅰ期(限于肾脏)为56～82％;Ⅱ期(扩展到肾周组织但在肾包膜之内)为43～100％; The survival rate after radical nephrectomy for surgical treatment of renal cell carcinoma was not significantly different from that obtained after simple nephrectomy, but radical nephrectomy was reasonable because 45% of the cases had metastases during the operation. 5-year survival rate: Phase I (limited to the kidneys) is 56 to 82%; Phase II (which extends to the renal tissue but within the renal capsule) is 43 to 100%;
