38例手术治疗腹膜后脂肪肉瘤病例分析

Report of 38 Cases of Retroperitoneal Liposarcoma Treated with Surgery

摘要: 目的：通过分析38例手术治疗的腹膜后脂肪肉瘤病例，探讨治疗复发性脂肪肉瘤的方法。方法：分析1987年6 月至2010年6 月辽宁省肿瘤医院共38例有完整随访资料的原发性脂肪肉瘤病历资料。结果：行2 次以上手术23例（60.5%），3 次以上手术11例（28.9%），联合脏器切除14例（36.8%），5 年生存率47.4% ，10年生存率28.9% 。结论：腹膜后脂肪肉瘤有术后易于复发的特点，对于复发病例争取再次手术是延长患者生存期的重要办法，扩大切除（包括联合脏器切除）是降低复发率的重要手段。

Abstract: Objective: To investigate the treatment methods for recurring retroperitoneal liposarcoma. Methods:Thirty eight cases of primary retroperitoneal liposarcoma were retrospectively analyzed with integrated follow-up from 1987 to 2010. Results: Twenty three cases had received two operations (60.5%),11cases had received more than two operations (28.9% ), 14cases had received resection combined with organs (36.8% ). The five-year survival rate was 47.4% and the ten-year survival rate was 28.9%.Conclusion:The tumor of retroperitoneal liposarcoma recurs easily. It is important to oper -ate on recurring tumors again to prolong survival time of the patients and to widen the margin including resection combined with organs for reducing rate of recurrence.
