目的 总结原发性腹膜后肿瘤(primary retroperitoneal tumor,PRT)的诊疗方法.方法 回顾性分析东南大学附属徐州医院1995年6月至2005年6月收治的60例PRT病人的临床资料.结果 60例病人肿瘤直径(13.5±6.5)cm,均经手术治疗,且经病理证实.其中16例良性肿瘤完整切除14例(87.5%);42例恶性肿瘤完整切除28例(66.7%);2例间质细胞潜在恶性肿瘤行完整切除,恶性肿瘤切除后切缘予以氩氦刀消融术20例.良、恶性肿瘤3年存活率分别为88.3%和21.6%.结论 完整切除肿瘤是治疗的关键和影响预后的重要因素.氩氦刀冷冻切缘有助于获得肿瘤的阴性切缘,改善预后.PRT的预后与手术的彻底性和病理类型相关.影像学检查对诊断有重要意义.

Diagnosis and treatment of primary retroperitoneal tumor:an analysis of 60 cases

??Objective:To summarize the strategy of diagnosis and the surgical managements of primary retroperitoneal tumor (PRT). Methods:The clinical and pathological data of 60 patients with PRT admitted between June 1995 to June 2005 in the Xuzhou Hospital Affiliated to Southeast University were analyzed retrospectively. Results:The average diameter of tumor was ??13.5±6.5??cm.Of the 16 patients with benign tumor,14 (87.5%) patients underwent complete surgical resection.Of the 42 patients with malignant tumor,28 (66.7%) patients underwent complete resection.Two patient with interstitialoma tumor underwent total resection.Twenty cases of malignant tumor underwent resection together with Ar??He targeted cryoablation. The 3??year survival rate of benign and malignant PRT was 88.3% and 21.6% respectively. Conclusion:Complete resection is the key for the treatment and diagnosis of PRT.Ar??He targeted cryoablation is advantageous to get negative incised margin to improve the survival of patients.The survival of the patients is related to surgical treatment and tumor malignant grade.Radiological study is crucial for the diagnosis.
