手术联合重组人p53腺病毒注射液治疗复发性恶性胶质瘤

目的 探讨手术联合重组人p53腺病毒注射液(rAd-p53)治疗复发性恶性胶质瘤的安全性和有效性.方法 38例复发性恶性胶质瘤患者再次行手术治疗.联合治疗组的18例患者术中埋放Ommaya储液囊,将1×1012VP rAd-p53经Ommaya储液囊注入瘤腔,每周1次,4周为1个疗程,连续2～4个疗程.手术组20例患者单纯行手术切除.两组患者均随访1年以上.结果 联合治疗组6个月生存率为66.7%,1年生存率为44.4%,中位生存期为9.7个月,较手术组(7.1个月)明显提高.联合治疗组术后6个月Karnofsky评分为(81.8±15.7)分,较术前明显提高(P＜0.05);术后1年Karnofsky评分为(66.1±17.4)分,明显高于手术组[(53.5±18.2)分,P＜0.05].结论 rAd-p53对于复发性恶性胶质瘤安全有效,能延长患者生存期,改善患者的生活质量.

Treatment of recurrent malignant gliomas by surgery combined with recombinant adenovirus-p53 injection

Objective To evaluate the efficacy and toxicity of combination therapy with surgery and recombinant adenovirus-p53 injection of recurrent malignant gliomas. Methods 38 patients with recurrent malignant gliomas were included in this study. Among them, 18 patients of combined treatment group had Ommaya reservoirs placed into the tumor cavities after the resection of the tumors and received regular recombinant adenovirus-p53 injections after the operation. The other 20 patients received surgery alone.Results The 6-month and 1-year survival rates after the combination therapy were 66.7% (14/18) and 44.4% (8/18), respectively. The median survival time was 9.7 months. Compared with the surgery-alone group, the combined treatment group achieved significant improvement (P ＜ 0.05). The Karnofsky score was significantly improved at 6 months after the combination therapy compared with that before the treatment (P ＜0.05). Conclusion The recombinant adenovirus-p53 injection is safe and effective in treatment of recurrent malignant gliomas. The combination therapy of surgery and recombinant adenovirus-p53 injection may improve the life quality and the prognosis in patients with recurrent malignant gliomas.
