原发性腹膜后肿瘤的诊治策略

The Study in Diagnosis and Treatment of Primary Retroperitoneal Tumors

【目的】总结原发性腹膜后肿瘤(PRT)的诊治经验。【方法】回顾性分析83例PRT的临床表现、影像学结果、病理类型及治疗情况。【结果】83例中33例为良性,50例为恶性。CT和MRI的诊断正确率分别为91.5%和100%。完整切除率为70.7%(53/75),完整切除复发患者再切除率为53.8%(7/13)。【结论】完备的术前评估对PRT的诊治有重要意义。手术完整切除是最佳的治疗方法。复发者应积极再次手术。

[Objective]To summarize the experience in diagnosis and treatment of primary retroperitoneal tumors （PRT）. [MethodslEighty-three cases of PRT from 1984 to 2004 were retrospectively analyzed in clinical manifestations,imaging findings, pathologic type and treatement. [Results]Thirty three cases were benign tumors and 50 malignant tumors. The diagnostic rate of CT was 91.5 %,and MRI was 100 %. The total resection rate was 70.70% （53/75）. After the total resection 7 （53.80%） relapsed patients got total resection again. [Conclusion]Full preoperative evaluations play an important role in diagnosis and treatment of PRT. Total resections are the best way of treatment. The recurrent tumor should be treated with reoperation.
