Objective： Irinotecan in combination with cisplatin for extensive-stage disease small-ceU lung cancer （ED-SCLC） patients has gained wide interest. Varying results for this treatment underpin the need for a synthesis of evidence. Methods： We conducted a literature-based meta-analysis to quantify the magnitude of the benefit comparing irinotecan in combination with cisplatin （IP） with etoposide in combination with cisplatin （EP） in ED-SCLC patients. The primary outcome was overall survival （OS） and progression-free survival （PFS）; secondary outcomes included overall response rate, 1- and 2-year survival rates, disease control rate and toxicity. Results： Four trials including 1,541 patients were identified in the analysis. No positive results （P〈0.05） were seen： OS （HR=0.85, CI95%=0.71-1.01; P=-0.08） with high heterogeneity （Chi2=7.76, dr=-3 [P=-0.05]; I2=61%）, PFS （HR=0.91, CI95%=0.74-1.28; P=-0.36） with high heterogeneity （Chi2=11.96, df=3 [P=-0.008]; I2=75%）, overall response rate（OR=1.16; CI95%=0.79-1.70; P=0.45）, disease control rate （OR=1.01; CI95%=0.74-1.38; P=0.95）, 1-year survival rate （OR = 1.30; CI95%=0.98-1.72; P=0.07） and 2-year survival rate （OR=1.97; CI95%=0.95-4.09; P=-0.07）. Fewer patients who received IP suffered severe hematologic toxicities （grade≥3）, such as neutropenia, thrombocytopenia and leucopenia. However, severe non-hematologic toxicities （grade≥3）, such as diarrhea, nausea, vomiting, fatigue, anorexia, and dehydration, were more common among patients who received IP. Conclusion： IP does not lengthen the overall survival or progression-free survival compared with EP in patients with ED-SCLC Fewer patients receiving IP had grade ≥ 3 hematological toxicities of nentropenia, leucopenia and thrombocytopenia, but more had grade≥3 diarrhea, nausea, vomiting, fatigue, anorexia and dehydration.

宏观经济与微观经济的现实结合和有效运行只能是计划与市场相结合的运行机制和运行模式。宏观经济的主导作用和微观经济的基础作用,通过市场有机地连接起来,使宏观经济与微观经济在互动中相互兼容、相互联系,实现国民经济在社会主义市场经济条件下健康、协调的运作。国家是宏观调控的主体,企业是宏观调控的基础,国家只有根据客观经济规律、形势,采取适度的调控措施,企业只有在发挥其自觉性和主动性的基础上,自觉地接受国家的宏观调控,才能实现宏观经济与微观经济互为补充、互相促进的理想发展状态。
