原发性腹膜后肿瘤71例的诊断和治疗

目的总结原发性腹膜后肿瘤的诊治经验。方法回顾性分析71例原发性腹膜后肿瘤患者的临床表现、病理类型、影像学检查、外科治疗等临床资料。结果71例患者均经手术治疗且诊断经病理证实。其中32例良性肿瘤完整切除31例(96·88%);38例恶性肿瘤完整切除29例(76·32%);1例交界性肿瘤行完整切除。良、恶性肿瘤5年生存率分别为89·29%和20·80%。良、恶性肿瘤术后复发再手术分别为4例(均完整切除)和13例(完整切除10例;部分切除3例)。结论影像学检查对诊断有重要意义。完整切除肿瘤是治疗的关键和影响预后的重要因素。

Diagnosis and treatment of primary retroperitoneal tumor in 71 cases

Objective To investigate the preopera ti ve diagnosis and the surgical treatment of primary retroperitoneal tumor(PRT). Methods The clinical dat a of 71 patients with PRT were retrospectively analyzed including clinical manif estation, radiologic studies, pathologic examination and surgical procedures. Results There were 32 cases of benign tumor, 38 cases of malignant tumor and 1 case of borderline tumor. Of the 32 patients with benign tumor, 31 underwent complete surgical resection. Of the 38 patients with malignant tumor, 29 underwent complete resection. One patie nt with borderline tumor underwent total resection. The 5-year survival rate of benign PRT was 89.29%, the 5-year survival rate of malignant PRT was 20.80%. Four cases of recurrent benign PRT underwent complete resection. Ten cases of r ecurrent malignant PRT underwent complete resection and 3 underwent partial rese ction. ConclusionsRadiolog ical study is crucial for the diagnosis. Complete resection is the key for the t reatment of PRT.
