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。
Objective To summarize the diagnosis and treatment of primary retroperitoneal tumor. Methods A retrospective analysis of 71 patients with primary retroperitoneal tumor clinical manifestations, pathological types, imaging studies, surgical treatment and other clinical data. Results 71 patients were surgically treated and confirmed by pathology. Among them, 31 cases (96.88%) were completely resected in 32 cases of benign tumors, 29 cases (76.32%) were completely resected in 38 cases of malignant tumors, and 1 case of borderline tumors was completely resected. The 5-year survival rates of benign and malignant tumors were 89.29% and 20.8% respectively. Four cases (complete resection) and 13 cases (complete resection in 10 cases, partial resection in 3 cases) were performed in both benign and malignant tumors. Conclusion Imaging examination is important for diagnosis. Complete resection of the tumor is the key to treatment and an important factor affecting the prognosis.
