摘要: 目的 观察负载抗原树突状细胞(dendritic cell,DC)活化TCR基因转染记忆性T细胞联合培美曲塞、顺铂治疗表皮生长因子受体络氨酸激酶抑制剂(epidermal growth factor receptor tyrosine kinase inhibitors,EGFR-TKI)耐药性晚期非小细胞肺癌(non-small cell lung cancer,NSCLC)的临床疗效及毒副反应。方法 41例EGFR-TKI耐药性晚期NSCLC患者分为联合治疗组和化疗组。联合治疗组21例,化疗前两天抽取患者外周血液进行DC活化T细胞增殖,化疗后14 d静脉回输该细胞,以培美曲塞500 mg/m2静脉滴注,d1;顺铂75 mg/m2静脉滴注,d1。每3周重复1次。化疗组20例,以培美曲塞500 mg/m2静脉滴注,d1;顺铂75 mg/m2,静脉滴注,d1。每3周重复1次。观察两组近期疗效、患者免疫功能的变化、生活质量和毒副反应等。结果 联合治疗组患者治疗后外周血液中CD3+、CD4+、CD8+、CD4+/CD8+、CD95+和CD122+明显增加,与治疗前比较差异有统计学意义(P均<0.05)。联合治疗组和化疗组有效率分别为33.33%和30.00%(P>0.05),疾病控制率分别为76.19%和60.00%(P<0.05)。中位疾病无进展时间联合治疗组为7.1个月,明显高于化疗组的3.7个月(P<0.05)。联合治疗组患者KPS评分改善率为85.71%,高于化疗组45.00%(P<0.05)。联合治疗组患者粒细胞减少、恶心呕吐和疲乏的发生率分别为46.6%、52.4%和23.8%,明显低于化疗组的75.0%、90.0%和65.0%(P<0.05)。结论 负载抗原DC活化TCR基因转染记忆性T细胞联合培美曲塞、顺铂治疗EGFR-TKI耐药性晚期NSCLC的疗效较好,能提高患者免疫功能和改善生活质量,减低化疗毒副反应,安全性较好。

Abstract:  Objective To examine whether infusion of antigen-activated memory T cells transfected with TCR genes alters the clinical efficacy and toxicity of pemetrexed-cisplatin combination chemotherapy to treatin the treatment of advanced non-small cell lung cancer resistant to EGFR-TKIs. Methods A total of 41 patients with non-small cell lung cancer were randomized into a group (n=20) that received standard chemotherapy involving a 3-week regime of pemetrexed(500 mg/m2) and cisplatin (75 mg/m2),or into a group(n=21) that received the same chemotherapy after harvesting, culturing and intravenously infusing DC-activated T cells.Curative effects,immune function, quality of life and adverse reactions were compared between the two treatments. Results Combining infu-sion of DC-activated T cells with chemotherapy significantly increased serum populations of CD3+,CD4+,CD8+,CD95+,and CD122+ cells,as well as the CD4+/CD8++ratio.Combination therapy and standard chemotherapy alone gave similar overall response rates of 33.33% and 30.00% (P>0.05),respectively,but combination therapy led to a significantly higher disease control rate(76.19% vs 60.00%, P<0.05),longer median progression-free survival (7.1 vs 3.7 months, P<0.05),and a higher rate of improvement in KPS (karnofsky performance status)improvement rate(85.71% vs 45.00%, P<0.05).At the same time,combination therapy was associated with much lower rates of neutropenia (46.6% vs 75.0%),nausea (52.4% vs 90.0%) and fatigue (23.8% vs 65.0%,P<0.05). Conclusion Combining infusion of antigen-activated memory T cells with pemetrexed and cisplatin chemotherapy improves therapeutic response and immune function while also reducing side effects when treating patients with advanced non-small cell lung carcinoma resistant to EGFR-TKIs.This promising therapeutic approach should be explored further.
