化疗联合干扰素诱导治疗进展期非小细胞肺癌的Meta分析

目的系统评价化疗联合干扰素(IFN)与单用化疗诱导治疗进展期非小细胞肺癌(NSCLC)的临床疗效及安全性。方法电子检索MEDLINE(1966～2006)、EMBASE(1984～2006.1)、Cochrane图书馆(2006年第1期)等数据库国外已发表和未发表的相关文献,手工检索相关会议的EducationBook及相关试验的参考文献。评价纳入研究的方法学质量,采用RevMan4.2.7软件进行Meta分析。结果共纳入5项随机对照试验,包括360例患者。Meta分析结果显示,化疗联合IFN诱导治疗与单用化疗相比,1年生存率RR0.76,95%CI(0.46,1.26),缓解率RR1.40,95%CI(0.83,2.34),白细胞减少RR2.61,95%CI(1.70,3.99),血小板减少RR4.78,95%CI(1.87,12.19)。结论现有证据表明,进展期NSCLC患者化疗联合IFN诱导治疗与单用化疗比较,并不能改善其1年生存率和缓解率,但有改善缓解率的倾向,而对1年生存率有降低作用,同时还会明显增加白细胞减少和血小板减少的发生率。本研究纳入病例较少,其结果尚需要多中心大样本随机对照试验进一步证实。

Meta-analysis of Induction Chemotherapy Combined with Interferon in Advanced Non-small Cell Lung Cancer

Objectives To evaluate the clinical effectiveness and safety of combined induction therapy of interferon (IFN) with chemotherapy for survival of the patients with advanced non-small cell lung cancer (NSCLC) by meta-analysis. Methods All clinical trials of addition of IFN plus chemotherapy versus chemotherapy alone for induction therapy to advanced NSCLC patients in MEDLINE (1966-2006), EMBASE (1984-2006.1) and The Cochrane Library (Issue 1,2006) were identified. The references of related studies and Education Books of ASCO and ESMO meeting were handsearched. The quality of included trials was evaluated. Data were extracted by two reviewers independently with a designed extraction form. RevMan 4.2.7 software was used for data analysis. Results Five randomized controlled trials involving 360 patients were included. The pooled result of 3 studies showed that IFN plus chemotherapy induction treatment did not improve 1-year survival rate with RR 0.76, 95%CI 0.46 to 1.26. The pooled result of 5 studies showed that IFN plus chemotherapy induction treatment did not improve response rate with RR 1.40, (0.83 2.34). The pooled result showed that IFN plus chemotherapy induction treatment might significantly increase leukopenia and thrombocytopenia with RR 2.61,95%CI1.70 to 3.99) and RR 4.78,95%CI 1.87 to 12.19 respectively . Conclusion Insufficient data exists to state whether IFN plus chemotherapy induction treatment can improve 1-year survival rate and response rate. IFN plus chemotherapy may increase occurrence of leucopenia and thrombocytopenia. Further studies are warranted.
