To analyze treatment and survival in 34 patients (28 resected) with primary or recurrent retroperitoneal sarcoma (RPS).
Between July 1994 and January 2001, 34 patients (15M, 19F; mean age: 56 years, range: 25-77) were evaluated. Complete resection was defined as removal of gross tumor with histologically confirmed clear resection margins.
Twenty-eight out of 34 patients (82%) (15 were affected by primary RPS, and 13 by recurrent RPS), underwent surgical exploration. Twenty-three patients had a grossly and microscopically complete resection, (3 having a grossly incomplete resection and 2 patients with a grossly complete resection having histologically involved resection margins). Twenty-one out of 28 patients (75%) underwent removal of contiguous intra-abdominal organs. Preoperative mortality was nil, and morbidity occurred in six cases only (21%). High tumor grade results a significant variable for a worse survival in all 28 patients (100% 5 years survival for low grade vs. 0% for high grade; P = 0.0004). Amongst completely resected patients, only histologic grade and peroperative blood transfusions affected disease-free survival (P = 0.04 and P = 0.05, respectively).
An aggressive surgical approach in both primary and recurrent RPS is associated with long-term survival.
分析34例原发性或复发性腹膜后肉瘤（RPS）患者（28例接受手术切除）的治疗及生存情况。
1994年7月至2001年1月期间，对34例患者（15例男性，19例女性；平均年龄：56岁，范围：25 - 77岁）进行了评估。完整切除定义为切除大体肿瘤且组织学证实切缘阴性。
34例患者中有28例（82%）（15例为原发性RPS，13例为复发性RPS）接受了手术探查。23例患者实现了大体和显微镜下的完整切除（3例大体切除不完整，2例大体切除完整但组织学切缘受累）。28例患者中有21例（75%）接受了毗邻腹腔内器官的切除。术前死亡率为零，仅6例（21%）出现并发症。肿瘤高分级是所有28例患者生存较差的显著变量（低分级5年生存率为100%，高分级为0%；P = 0.0004）。在完全切除的患者中，只有组织学分级和术中输血影响无病生存期（分别为P = 0.04和P = 0.05）。
原发性和复发性RPS均采取积极的手术方法与长期生存相关。
