摘  要:目的:探讨颅内血管周细胞瘤的临床特点及其治疗。方法:回顾性分析31例颅内血管周细胞瘤患者的临床特征、影像学和病理学表现及其治疗方法,观察患者的无进展生存(progression—freesurvival,PFS)时间,比较不同治疗方法之间的差异。结果:31例颅内血管周细胞瘤患者均进行了手术治疗及手术后放疗。16例患者进行了肿瘤全部切除(grosstotalremoval,GTR)及手术后分次外放射治疗(externalbeamradiationtherapy,EBRT)。15例患者进行了肿瘤部分切除(subtotalremoval,STR),其中6例患者手术后进行了EBRT,9例患者手术后进行了伽玛刀手术(gammaknifesurgery,GKS)。GTR组患者的中位PFS(89个月,64~126个月)明显长于STR组(49个月,26~81个月),差异有统计学意义(P〈0.01)。而STR组中手术后接受EBI玎患者的中位PFS(49个月,26~81个月)与GSK患者的中位PFS(47个月,29~78个月)之间的差异无统计学意义(P〉0.05)。结论:GTR结合手术后放疗是治疗颅内血管周细胞瘤的有效方法。Objective: To discuss the clinical features and treatment of intracranial hemangiopericytoma (HPC). Methods: The medical records including clinical features, imaging features, pathological results and treatment methods in 31 patients with HPC were reviewed retrospectively. To compare the difference in progression-free survival (PFS) among patients receiving different treatments. Results: Thirty-one patients with initial HPC were treated with operation and radiation. Gross total removal (GTR) was achieved in 16 patients, followed by postoperative adjuvant fractionated external beam radiation therapy (EBRT). Of 15 patients with subtotal removal (STR), 6 patients accepted EBRT, and 9 patients were treated with adjuvant gamma knife surgery (GKS). The median PFS of patients with GTR (89 months, 64-126 months) was longer than that of patients with STR (49 months, 26-81 months) (P 〈 0.01). However, there was no significant difference in the median PFS of patients with STR between undergoing EBRT (49 months, 26-81 months) and GKS (47 months, 29-78 months) (P 〉 0.05). Conclusion: GTR followed by adjuvant radiation provides patients with a better outcome.
