原发性已转移肾腺癌(PMRAC)约占初诊肾癌的1/3,预后恶劣,中位数生存时间约为12月。化疗、放疗及激素治疗大多徒劳无功,辅助性肾切除亦难能延长生命。已有作者提出肾栓塞后延迟肾切除可改善这些患者的生命率,
Primary metastatic renal adenocarcinoma (PMRAC) accounts for about one-third of the newly diagnosed renal cell carcinomas and has a poor prognosis with a median survival time of approximately 12 months. Chemotherapy, radiotherapy and hormone therapy are mostly futile and assisted nephrectomy can hardly prolong life. The authors have suggested that delayed nephrectomy after renal embolism can improve the survival rate of these patients.
