目的探讨成人原发性腹膜后恶性肿瘤(APRMT)的诊断方法和手术经验。方法对1990年1月至2003年4月经手术治疗的98例 APRMT 患者的临床资料进行分析。结果 98例成人原发性腹膜后恶性肿瘤中,肿瘤完全切除79例(80.6%),姑息性切除16例(16.3%),肿瘤探查和单纯活检3例(3.1%),合并脏器切除25例(25.5%);复发再次手术者28例(28.6%)。肿瘤完全切除的79例患者的1、3、5年生存率分别为93.7%、73.4%和34.2%,姑息性切除的1、3、5年生存率分别为75.0%、6.3%和6.3%。结论联合应用合理的影像学检查对判断 APRMT 肿瘤周围器官是否受累和切除范围有重要意义,充分的术前准备和受累器官的联合切除可以提高 APRMT 切除率和预后,对于复发病例,应争取尽早再次手术治疗。
Objective To investigate the diagnosis and surgical experience of adult primary retroperitoneal malignancies (APRMT). Methods Clinical data of 98 patients with APRMT surgically treated between January 1990 and April 2003 were analyzed. Results In 98 cases of primary primary retroperitoneal malignancy, 79 cases (80.6%) were completely resected, 16 cases (16.3%) were treated by palliative resection, 3 cases (3.1%) were detected by tumor and simple biopsy, Cases (25.5%); recurrent reoperation in 28 cases (28.6%). The 1, 3, 5-year survival rates of 79 patients with complete tumor resection were 93.7%, 73.4% and 34.2%, respectively. The 1, 3 and 5-year survival rates of palliative resection were 75.0%, 6.3% and 6.3%, respectively. Conclusions The combined application of reasonable imaging examination is of great significance to determine whether the organs around APRMT are involved and resection scope. Adequate preoperative preparation and organ resection can improve the resection rate and prognosis of APRMT. For recurrent cases, Surgical treatment.
