A series of 108 renal tumour nephrectomies carried out between 1975 and 1984 was studied to determine the prognostic statistical significance of the relationship between venous involvement and various pathological features. Tumour size, spread, histological grade and lymph node involvement were compared between V0 tumours (58%), V1 (32%) and V2 tumours (10%). Actuarial 5-year survival rates revealed a poor prognosis with venous involvement (V0 66%, V1 27%, V2 33%). Tumours larger than 10 cm with perirenal spread and of higher histological grade were significantly related to venous involvement. Survival between renal vein involvement and inferior vena caval extension was statistically similar, but it was influenced by tumour size and higher grade. Perirenal spread and nodal involvement were poor indicators.
对1975年至1984年间进行的108例肾肿瘤肾切除术进行了研究，以确定静脉受累与各种病理特征之间关系的预后统计学意义。比较了V0肿瘤（58%）、V1（32%）和V2肿瘤（10%）的肿瘤大小、扩散情况、组织学分级和淋巴结受累情况。精算5年生存率显示静脉受累预后较差（V0为66%，V1为27%，V2为33%）。大于10 cm、有肾周扩散且组织学分级较高的肿瘤与静脉受累显著相关。肾静脉受累和下腔静脉延伸之间的生存率在统计学上相似，但受肿瘤大小和较高分级的影响。肾周扩散和淋巴结受累是不良指标。
