自体和半相合异体细胞因子诱导的杀伤细胞联合化疗治疗非小细胞肺癌的临床疗效评价

 目的　评价自体和半相合异体细胞因子诱导的杀伤（CIK）细胞联合化疗治疗非小细胞肺癌（NSCLC）的临床疗效及安全性。方法　选择42例NSCLC患者为研究对象，按照成组匹配原则将病例分为3组：自体CIK细胞联合化疗组（自体CIK组），半相合异体CIK细胞联合化疗组（异体CIK组），单纯化疗组。观察自体和异体CIK细胞免疫治疗的安全性，流式细胞术（FCM）分析比较各治疗组治疗前后体内T细胞亚群变化，并对3组的临床近期疗效进行比较。结果　FCM检测结果显示，自体与异体CIK组CIK细胞输注后CD+3、CD+4／CD+8比值、NK细胞（CD-3 CD+56）和CIK细胞（CD+3 CD+56）比例较治疗前明显升高，自体CIK组治疗前分别为（47.2±10.1）%、1.0±0.1、（15.1±2.7）%、（0.7±0.2）%。治疗后分别为（58.8±12.3）%、1.3±0.2、（24.6±7.1）%、（3.8±2.2）%；异体CIK组治疗前为（49.4±11.4）%、0.9±0.2、（14.8±3.2）%、（0.9±0.3）%，治疗后为（57.3±9.2）%、1.4±0.3、（25.4±6.7）%、（4.3±2.6）%，差异有统计学意义（t值分别为22、20、19，均P＜0.05），而单纯化疗组治疗前后T细胞亚群水平未见明显改变。临床近期疗效比较结果显示，自体及异体CIK细胞治疗组客观有效率和疾病控制率（分别为35.7 %、28.6 %和64.3 %、71.4 %）均稍高于单纯化疗组（21.4 %、57.1 %），但差异无统计学意义（χ2＝38.85、χ2＝41.24，均P＞0.05）。结论　自体或半相合异体CIK细胞免疫治疗安全性好、毒副作用低，有一定的近期疗效，可有效延缓肿瘤复发，是一种值得在临床上推广的肿瘤辅助治疗模式。

Evaluation about clinical curative effect of treatment of non-small cell lung cancer with autologous and half consistency allograft cytokines induced killer cells combined with chemotherapy

Objective To evaluate the clinical efficacy and safety of treatment of non-small cell lung cancer (NSCLC) with autologous and half consistency allograft cytokines induced killer cells combined with chemotherapy. Methods We selected 42 patients with NSCLC patients as the research object. According to the group matching principle, the cases were divided into three groups: autologous CIK cells combination chemotherapy group, half consistency allograft CIK cells combination chemotherapy group, pure chemotherapy group. The autologous and allograft CIK cellular immune therapy of security, flow cytometric analysis technique (FCM) comparisons between before and after the treatment group infusion in vivo T lymphocyte subsets changes, and three treatment group clinical short-term curative effect were used in the comparison.Results FCM detection results show that CIK cell infusion after, CD+3, CD+4 / CD+8 ratio, NK cells (CD+3 CD+56)and CIK cells (CD+3 CD+56) ratio obviously higher than before treatment, autologous infusion before treatment,respectively (47.2±10.1) %, 1.0±0.1, (15.1±2.7) %, (0.7±0.2) %. After treatment respectively (58.8±12.3) %,1.3±0.2, (24.6±7.1) %, (3.8±2.2) %; Allograft infusion before treatment for (49.4±11.4) %, 0.9±0.2, (14.8±3.2) %, (0.9±0.3) % for after treatment (57.3±9.2) %, 1.4±0.3, (25.4±6.7) %, (4.3 ± 2.6) % (t = 22, 20, 19,P ＜ 0.05), and the pure chemotherapy group before and after the treatment T lymphocyte subsets level has not seen the obvious change. Clinical short-term curative effect comparison, autologous and allograft CIK cell therapy group objective efficient and disease control rates are slightly higher than the pure chemotherapy group, but the difference was not statistically significant. Respectively 21.4 %, 57.1%, and 35.7 %, 28.6 %,64.3 %, 71.4 % (x2=38.85, x2=41.24, P ＞ 0.05). Conclusion Autologous or half consistency allograft CIK cellular immune therapy is good safety and low toxicity, have certain short-term curative effect, which can effectively slowed tumor recurrence, is a worthy of popularizing clinically tumor adjuvant treatment mode.
