原发性腹膜后肿瘤手术后复发因素分析

Postoperative recurrent factors of primary retroperitoneal tumor

目的 探讨原发及复发腹膜后肿瘤手术治疗经验 ,并分析影响肿瘤术后复发的因素。方法 回顾性分析 1983～ 2 0 0 0年原发性腹膜后肿瘤 35 2例 ,并进行术后肿瘤复发的多因素回归分析。结果 手术 30 8例 ,恶性肿瘤 188例 ,良性肿瘤 12 0例。多因素分析显示 :男性、恶性肿瘤、肿瘤残留者、肿瘤与腹主动脉关系密切者易复发 ,脂肪肉瘤、平滑肌肉瘤、血管外皮细胞肉瘤是易复发的病理类型。结论 原发及复发性腹膜后肿瘤多数可行手术治疗 ,通过对影响复发诸因素分析可预测患者的预后。

Objective To study surgical treatment experience in primary and recurrent retroperitoneal tumor and analyze the postoperative recurrent factors. Method The clinical data of 352 cases of primary retroperitoneal tumor from 1983 to 2000 were retrospectively analyzed and the multiple regression analysis performed on postoperative recurrent factors. Results Operations were performed on 308 cases, including 188 cases of malignant tumor and 120 cases of benign tumor. Multiple factor regression analysis showed that the male patients with malignant tumor with un complete resection or with involvement in abdominal aorta had tendency to recurrence. Liposarcaoma, leiomyosarcoma and vascular pericyte sarcoma were the pathological types to recurrent. Conclusion Large amount of primary and recurrent retroperitoneal tumor cases could be resected. The analysis on the factors influencing the recurrence could predict the prognosis of the patients.
