  目的   评价细胞因子诱导的杀伤细胞（cytokine-induced killer cells,CIK）联合化疗治疗非小细胞肺癌（non-small cell lung cancer,NSCLC）的临床疗效。   方法   收集天津医科大学附属肿瘤医院2003年1月至2008年3月接受CIK细胞联合化疗治疗的87例NSCLC患者作为联合治疗组,接受单纯化疗的87例NSCLC患者作为对照组。Ⅰ~ⅢA期为早期,Ⅳ期为晚期。配对因素包括性别、年龄、吸烟情况、病理类型、KPS评分、临床分期、是否手术、乳酸脱氢酶（lactate dehydrogenase,LDH）、血小板、血红蛋白、治疗情况等。观察终点为无进展生存期（progression-free survival,PFS）和总生存期（overall survival,OS）。对于未取得中位OS或PFS组用平均OS或PFS表示。   结果   联合治疗组与单纯化疗组2年PFS率分别为47%、36%（P < 0.05）,2年OS率分别为71%、43%（P < 0.001）。两组患者中位PFS分别为24、12个月（P < 0.05）,中位OS分别为48、18个月（P=0.001）。早期患者中联合治疗组与单纯化疗组2年PFS率、中位PFS差异无明显统计学意义（74% vs. 58%,P=0.138;57个月vs. 45个月,P=0.093）,联合治疗组2年OS率及中位OS明显高于单纯化疗组（92% vs. 72%,P < 0.05;73个月vs. 53个月,P < 0.05）。晚期患者中联合治疗组与单纯化疗组2年PFS率分别为13%、5%（P < 0.001）,2年OS率分别为42%、3%（P < 0.001）,两组患者中位PFS分别为13、6个月（P=0.001）,中位OS分别为24、10个月（P=0.001）。多因素分析显示临床分期及CIK治疗周期数是联合治疗组肺癌患者的独立预后因素。   结论   CIK细胞联合化疗能够延长肺癌患者的总体生存时间,并延长晚期患者的无进展生存时间,显著改善肺癌患者预后。CIK细胞治疗多于7个周期者疗效更好。      

含铂双药对比非铂单药二线治疗晚期非小细胞肺癌的系统评价

目的系统评价联合铂类的双药方案和非铂类单药方案二线治疗晚期非小细胞肺癌(non-small cell lung cancer,NSCLC)患者的有效性及安全性。方法计算机检索PubMed、The Cochrane Library、Web of science、中国生物医学文献数据库(CBM)、中国期刊全文数据库(CNKI)和万方数据库,收集含铂双药化疗方案对比非铂单药化疗方案二线治疗晚期NSCLC的随机对照试验,用RevMan 5.2进行荟萃分析。结果最终纳入11项临床随机对照试验,共1 167例患者。Meta分析结果显示,与非铂单药方案相比,含铂双药方案化疗可提高晚期NSCLC患者的化疗客观有效率(overall response rate,ORR)及疾病控制率(disease control rate,DCR),分别为1.43倍(RR=1.43,95%CI为1.08~1.89,P=0.010)和1.16倍(RR=1.16,95%CI为1.05~1.27,P=0.002)。同时,含铂双药方案化疗亦可延长晚期NSCLC患者的无进展生存期(progression-free survival,PFS),HR=0.74,95%CI为0.58~0.95,P=0.020;但含铂双药化疗与非铂单药化疗组1年生存率差异无统计学意义,RR=1.21,95%CI为0.91~1.61,P=0.190。安全性方面,含铂双药方案化疗最主要的不良反应为血小板减少,RR=2.99,95%CI为1.95~4.59,P<0.001;而3~4级白细胞减少、中性粒细胞减少、恶心呕吐和贫血等不良反应,含铂双药化疗与非铂单药化疗组差异均无统计学意义。结论与非铂单药化疗方案相比,含铂双药方案可提高晚期NSCLC患者化疗ORR及DCR,延长晚期NSCLC患者的PFS,但不能明显改善1年生存率。最主要不良反应为血小板减少,低毒耐受性好。因此,含铂双药化疗方案在一线治疗失败的晚期NSCLC患者的二线治疗中值得进一步推广。     

替吉奥联合顺铂治疗晚期非小细胞肺癌的临床疗效

Gefitinib in combination with gemcitabine and cisplatin in advanced non-small-cell lung cancer: a phase III trial--INTACT 1.

PURPOSE: The purpose of this study was to determine whether the addition of the epidermal growth factor receptor tyrosine kinase inhibitor gefitinib (Iressa, ZD1839; AstraZeneca, Wilmington, DE) to standard first-line gemcitabine and cisplatin provides clinical benefit over gemcitabine and cisplatin alone in patients with advanced or metastatic non-small-cell lung cancer (NSCLC). Gefitinib has demonstrated encouraging efficacy in advanced NSCLC in phase II trials in pretreated patients, and a phase I trial of gefitinib in combination with gemcitabine and cisplatin showed favorable tolerability. PATIENTS AND METHODS: This was a phase III randomized, double-blind, placebo-controlled, multicenter trial in chemotherapy-naive patients with unresectable stage III or IV NSCLC. All patients received up to six cycles of chemotherapy (cisplatin 80 mg/m(2) on day 1 and gemcitabine 1,250 mg/m(2) on days 1 and 8 of the 3-week cycle) plus either gefitinib 500 mg/d, gefitinib 250 mg/d, or placebo. Daily gefitinib or placebo was continued until disease progression. End points included overall survival (primary), time to progression, response rates, and safety evaluation. RESULTS: A total of 1,093 patients were enrolled. There was no difference in efficacy end points between the treatment groups: for the gefitinib 500 mg/d, gefitinib 250 mg/d, and placebo groups, respectively, median survival times were 9.9, 9.9, and 10.9 months (global ordered log-rank [GOLrank] P =.4560), median times to progression were 5.5, 5.8, and 6.0 months (GOLrank; P =.7633), and response rates were 49.7%, 50.3%, and 44.8%. No significant unexpected adverse events were seen. CONCLUSION: Gefitinib in combination with gemcitabine and cisplatin in chemotherapy-naive patients with advanced NSCLC did not have improved efficacy over gemcitabine and cisplatin alone. The reasons for this remain obscure and require further preclinical testing.     

Costs of bevacizumab and pemetrexed for advanced non-squamous NSCLC in Italy and Germany

The new targeted agent bevacizumab in combination with cisplatin and gemcitabine, and a third-generation chemotherapy pemetrexed in combination with cisplatin, have been approved as first-line treatment for patients with advanced non-squamous non-small cell lung cancer (NSCLC). An indirect comparison between bevacizumab plus cisplatin and gemcitabine and pemetrexed plus cisplatin showed that bevacizumab (plus cisplatin and gemcitabine) achieved a favourable hazard ratio in terms of progression-free survival among patients with advanced NSCLC. This analysis aimed to compare the monthly cost of these treatments for advanced non-squamous NSCLC in Italy and Germany.The comparison used country specific cost data and adopted the payer perspective in Italy and Germany.The monthly cost of bevacizumab, including administration cost, as a single agent was €1,509 and €2,564 less than pemetrexed in Italy and Germany, respectively. The monthly treatment cost of bevacizumab plus cisplatin and gemcitabine was €1,001 and €446 less than pemetrexed plus gemcitabine in Italy and Germany, respectively.Results indicate that clinical benefits with bevacizumab plus cisplatin and gemcitabine therapy are achieved at a lower monthly cost than pemetrexed plus gemcitabine doublet therapy. Therefore, from a budget perspective, bevacizumab should be considered as a preferred targeted treatment of choice for advanced non-squamous NSCLC.

Cisplatin and gemcitabine first-line chemotherapy followed by maintenance gemcitabine or best supportive care in advanced non-small cell lung cancer: a phase III trial

PURPOSE: The primary objective of this randomized phase III study was to show significant difference in median time to progression (TTP) in patients with advanced NSCLC treated with single-agent gemcitabine maintenance therapy versus best supportive care following gemcitabine plus cisplatin initial first-line therapy. PATIENTS AND METHODS: Chemonaive patients with stage IIIB/IV NSCLC received gemcitabine 1,250 mg/m(2) (days 1 and 8) plus cisplatin 80 mg/m(2) (day 1) every 21 days. Patients achieving objective response or disease stabilization following initial gemcitabine plus cisplatin therapy were randomized (2:1 fashion) to receive maintenance gemcitabine (1,250 mg/m(2) on days 1 and 8 every 21 days) plus best supportive care (GEM arm), or best supportive care only (BSC arm). RESULTS: Between November 1999 and November 2002, we enrolled 352 patients (median age: 57 years; stage IV disease: 74%; Karnofsky performance status (KPS) >80: 41%). Following initial therapy, 206 patients were randomized and treated with gemcitabine (138) or best supportive care (68). TTP throughout the study period was 6.6 and 5 months for GEM and BSC arms, respectively, while values for the maintenance period were 3.6 and 2.0 months (for p < 0.001 for both). Median overall survival (OS) throughout study was 13.0 months for GEM and 11.0 months for BSC arms (p = 0.195). The toxicity profile was mild, with neutropenia being most common grade 3/4 toxicities. CONCLUSION: Maintenance therapy with gemcitabine, following initial therapy with gemcitabine plus cisplatin, was feasible, and produced significantly longer TTP compared to best supportive care alone. Further studies are warranted to establish the place of maintenance chemotherapy in patients with advanced NSCLC.     

Phase III trial of gemcitabine plus cisplatin versus cisplatin alone in patients with locally advanced or metastatic non-small-cell lung cancer.

PURPOSE: The Hoosier Oncology Group has previously reported the results of its phase II trial of the combination of cisplatin plus gemcitabine. In that study of 27 assessable patients with advanced or metastatic non-small-cell lung cancer (NSCLC), the response rate was 33%, with a median survival of 8.4 months. Based on such favorable results, the Hoosier Oncology Group designed this randomized phase III study of gemcitabine plus cisplatin compared with cisplatin alone in chemotherapy-naive patients with advanced NSCLC. PATIENTS AND METHODS: Patients were randomized to receive either cisplatin (100 mg/m(2) intravenously on day 1 of a 28-day cycle) or the combination of cisplatin (100 mg/m(2) intravenously on day 1) plus gemcitabine (1,000 mg/m(2) administered intravenously on days 1, 8, and 15 of a 28-day cycle). RESULTS: From August 1995 to February 1997, 522 assessable chemotherapy-naive patients were randomized. Toxicity was predominantly hematologic and was more pronounced in the combination arm, with grade 4 neutropenia occurring in 35.3% of patients compared with 1.2% of patients on the cisplatin monotherapy arm. The incidence of neutropenic fevers was less than 5% in both arms. Grade 4 thrombocytopenia occurred in 25. 4% of patients on the combination arm compared with 0.8% of patients on the cisplatin monotherapy arm. No serious hemorrhagic events related to thrombocytopenia were reported for either arm. The combination of gemcitabine plus cisplatin demonstrated a significant improvement over single-agent cisplatin with regard to response rate (30.4% compared with 11.1%, respectively; P <.0001), median time to progressive disease (5.6 months compared with 3.7 months, respectively; P =.0013), and overall survival (9.1 months compared with 7.6 months, respectively; P =.004). CONCLUSIONS: For the first-line treatment of NSCLC, the regimen of gemcitabine plus cisplatin is superior to cisplatin alone in terms of response rate, time to disease progression, and overall survival.

ATP生物荧光肿瘤体外药敏检测技术指导复发合并恶性胸腔积液的非小细胞肺癌的治疗

Objective: This study was aimed to research the feasibility of ATP-bioluminescence assay (ATP-TCA) guiding the treatment on recurrent non-small cell lung cancer (NSCLC) combined with malignant pleural effusion. Methods: We collected 30 pleural fluid samples which were approved to be positive by cytology from recurrent NSCLC patients. These cells were cocultured with chemotherapy medicines, single agent or drugs combination. Five drug concentrations, two parallel holes were examined in vitro for 4 days, the results were measured by adding luciferase-fluorescein working system and luminescence analyzer. We applied chemotherapy medicines according to the results in vitro of ATP-TCA. Results: There were differences among drug sensitivities of individuals. All the samples could be evaluated. Effective single drugs included cisplatinum, mitomycin C, doxorubicin, and pemetrexed disodium; sensitive drugs in the combination therapy were gemcitabine plus cisplatin, vinorelbine plus cisplatin, paclitaxel plus cisplatin, docetaxel plus cisplatin, and mitomycin C, vindesine plus cisplatin, in which gemcitabine + cispiatin (GEM + DDP) in vitro was the most efficient program. Conclusion: ATP-TCA in vitro sensitivity assay is rapid, reliable, and simple to guide the treatment of recurrent NSCLC with malignant pleural effusion, and can help clinicians to make the individual chemotherapy program.     

Three-arm randomized study of two cisplatin-based regimens and paclitaxel plus gemcitabine in advanced non-small-cell lung cancer: a phase III trial of the European Organization for Research and Treatment of Cancer Lung Cancer Group--EORTC 08975.

PURPOSE: To compare the therapeutic efficacy of paclitaxel plus cisplatin (arm A) versus gemcitabine plus cisplatin (arm B) and arm A versus paclitaxel plus gemcitabine (arm C) in chemotherapy-naive patients with advanced non-small-cell lung cancer (NSCLC).Materials and METHODS: Patients were randomly assigned to receive either paclitaxel 175 mg/m2 (3-hour infusion, day 1) or gemcitabine 1,250 mg/m2 (days 1 and 8) both combined with cisplatin 80 mg/m2 (day 1) or paclitaxel 175 mg/m2 (3-hour infusion, day 1) combined with gemcitabine 1,250 mg/m2 (days 1 and 8). Primary end point was comparison of overall survival for B versus A and C versus A. Secondary end points included response rate and duration, progression-free survival, toxicities, quality of life [QoL], and cost of treatment. RESULTS: Four hundred eighty patients (arm A, 159; arm B, 160; arm C, 161 patients) were enrolled; all baseline characteristics were balanced. Median survival times were as follows: arm A, 8.1 months; arm B, 8.9 months; arm C, 6.7 months. Response rates were 31.8% for arm A, 36.6% for arm B, and 27.7% for arm C. Other than myelosuppression (B v A, P <.005), no statistically or clinically significant differences were observed for secondary end points. The average treatment costs were 25% higher in arm C as compared with arms A and B. CONCLUSION: Gemcitabine plus cisplatin and paclitaxel plus gemcitabine do not increase overall survival in patients with advanced NSCLC as compared with paclitaxel plus cisplatin. Treatment was well tolerated, and most QoL parameters were similar, but costs associated with the nonplatinum arm were highest.     

Gemcitabine/carboplatin in advanced non-small cell lung cancer

Gemcitabine/cisplatin is among the most widely used regimens in Europe for first-line treatment of non-small cell lung cancer (NSCLC). Problems with cisplatin use in this setting include significant nonhematologic toxicity and difficulty of use in outpatients. Carboplatin constitutes a reasonable alternative to cisplatin in this combination, since it shows synergy with gemcitabine in vitro, is easier to use in ambulatory patients, and has a better nonhematologic toxicity profile. Studies of gemcitabine/cisplatin on a 28-day schedule (gemcitabine on days 1, 8, 15 and carboplatin on day 1) generally indicate excessive thrombocytopenia. Use of a 21-day schedule (e.g. gemcitabine on days 1 and 8, carboplatin on day 1) is associated with reduced toxicity and comparable efficacy. Results of one randomized phase II study suggest reduced toxicity and reduced objective response rate with gemcitabine/carboplatin versus gemcitabine/cisplatin. We are currently conducting a phase III comparison of gemcitabine 1200 mg/m(2) on days 1 and 8 plus carboplatin at an area under the curve of 5 mg/ml/min on day 1 versus gemcitabine at the same dose plus cisplatin 80 mg/m(2) on day 1 every 21 days in chemotherapy-nai;ve patients with stage IIIB/IV NSCLC; interim analysis indicates comparable response rates (47 and 48%). A better understanding of the relative toxicities of these regimens should be provided by the final results of this trial.     

吉西他滨联合顺铂一线治疗晚期NSCLC的疗效及相关因素分析

目的评价吉西他滨联合顺铂一线治疗晚期非小细胞肺癌(NSCLC)的疗效,并探讨影响化疗疗效及预后的相关因素。方法回顾性分析113例至少接受2周期吉西他滨联合顺铂方案(GP方案)化疗的ⅢB～Ⅳ期NSCLC患者,评价疗效及不良反应;Kaplan-Meier法分析生存情况,Cox回归法进行多因素预后分析。结果GP方案的总有效率43.8%,临床特点未能预测疗效;中位无进展生存时间67月,中位生存时间16.7月。主要不良反应为1~2级骨髓抑制和胃肠道反应;多因素分析示吸烟状况、远处器官转移数目、肝脏转移、化疗周期数是影响预后的独立因素。结论GP方案治疗晚期NSCLC具有较高的疗效,不良反应低。吸烟、远处器官转移数目1个以上、肝脏转移是晚期NSCLC预后不良的因素;GP方案化疗4~6个周期能明显改善预后。
