腹膜后恶性肿瘤出现症状时已可生长巨大,并侵犯邻近组织及器官,手术不能切除的高达83%,手术死亡率10～25%。“彻底”切除者10年生存率为4～21%,而术后局部复发率可达80%。术后放疗改善疗效甚微,其2～16年生存率约为10～19%。作者指出各家均认为单独放疗或单独化疗对未能切除的腹膜后肿瘤(经血管造影或手术不能切除所证实)均无希望。本文报告8例(横纹肌肉瘤、恶性间胚叶肿瘤、腰椎尤文氏肉瘤伴腹膜后广泛 The symptoms of retroperitoneal malignant tumors can grow tremendously and invade neighboring tissues and organs. Up to 83% of the patients can’t be removed by surgery, and the surgical mortality is 10-25%. The 10-year survival rate for “complete” resection was 4 to 21%, and the local recurrence rate after surgery was 80%. Postoperative radiotherapy has little effect, and its 2 to 16-year survival rate is about 10 to 19%. The authors pointed out that each individual considered that radiotherapy alone or chemotherapy alone had no hope of failing to remove retroperitoneal tumors (as confirmed by angiography or surgical resection).
