目的:总结并探讨原发性腹膜后肿瘤(PRPT)的诊断及治疗方法。方法:回顾并分析2004年1月至2009年12月收治的46例腹膜后肿瘤患者的临床资料及随访结果。结果:良性肿瘤17例,完整切除15例,部分切除2例,复发4例,均再次手术;恶性肿瘤29例,完整切除10例,部分切除15例,活检2例,复发6例,再次手术4例。随访时间0.5至5年,良性肿瘤死于其他疾病3例,死于原发性腹膜后肿瘤1例;恶性肿瘤死亡22例,其中1年内死亡8例,3年内死亡12例,5年内死亡2例。结论:对原发性腹膜后肿瘤,B超、CT及MRI检查是目前诊断PRPT方便、有效的诊断手段,手术治疗是治疗PRPT的首选治疗方式,完整切除肿瘤是影响PRPT治疗效果及其预后的重要因素。对于复发病例应选择再次手术治疗。
Objective: To summarize and discuss the diagnosis and treatment of primary retroperitoneal tumor (PRPT). Methods: The clinical data and follow-up results of 46 patients with retroperitoneal tumors admitted from January 2004 to December 2009 were retrospectively analyzed. Results: There were 17 benign tumors, complete resection in 15 cases, partial resection in 2 cases and recurrent cases in 4 cases, all underwent reoperation. Malignant tumors were 29 cases, complete resection in 10 cases, partial resection in 15 cases, biopsy in 6 cases and recurrence in 6 cases 4 cases. Followed up for 0.5 to 5 years, benign tumors died of other diseases in 3 cases, died of primary retroperitoneal tumor in 1 case; 22 cases of malignant tumor death, including 8 cases of death within 1 year, 12 cases within 3 years, 5 years of death 2 example. Conclusion: The diagnosis of primary retroperitoneal tumor, B-ultrasound, CT and MRI is a convenient and effective diagnostic method for diagnosis of PRPT. Surgical treatment is the preferred treatment for PRPT. Complete resection of the tumor is the treatment of PRPT and its prognosis Key factor. For recurrent cases should choose to re-surgery.
