Abstract:Objective To observe the clinical efficacy of multi-course DC-CIK in the treatment of advanced lung cancer. Methods ?86 patients with lung cancer after chemotherapy from December 2014 to December 2018 were enrolled. The patients were divided into the control group and the experimental group by random number table, 43 cases each. The control group received one course of DC-CIK treatment, and the experimental group received three courses of DC-CIK treatment. The therapeutic effects, lymphocyte levels, cytokine levels, tumor marker expression, and adverse reactions were compared between the two groups.Results ?The disease control rate (69.77%) in the experimental group was higher than that in the control group (41.86%). The expressions of CD4+,CD4+/CD8+ and NK in the two groups were higher than those before treatment, and the experimental group was higher than the control group (P<0.05).The expression of CD8+ in the two groups decreased after treatment, and the experimental group was lower than the control group (P<0.05). There was no significant change in IL-4, IL-6 and IL-10 before and after treatment (P>0.05). The latter two groups of IL-2, TNF-α, IFN-γ were higher than before treatment, and with the increase of treatment times, IL-2, TNF-α, IFN-γ increased gradually(P<0.05).After treatment, AFP, NSE and CYfra21-1 were lower than those before treatment(P<0.05); CEA increased after the first treatment in both groups (P<0.05); CEA decreased after the last treatment in the experimental group(P<0.05); no adverse reactions occurred in either group.Conclusion ?Multi-course DC-CIK immunotherapy is effective in the treatment of advanced lung cancer. It can effectively remove tumor cells and has no side effects.

本研究86例患者中,有5例治療前白細(xì)胞低于正常值,給予200 mg GM-CSF刺激,72 h后檢測(cè)血常規(guī),待白細(xì)胞正常,采血行DC-CIK治療。本研究結(jié)果顯示,實(shí)驗(yàn)組疾病控制率(69.77%)高于對(duì)照組(41.86%)。第一次治療后兩組CEA較治療前升高,在末次治療后實(shí)驗(yàn)組CEA與第一次治療前相比出現(xiàn)下降。治療后兩組AFP、NSE、CYfra21-1均較治療前下降,表明DC-CIK治療可以降低肺癌患者的腫瘤標(biāo)志物,對(duì)腫瘤的持續(xù)殺傷具有很好的作用。研究發(fā)現(xiàn),實(shí)驗(yàn)組CEA出現(xiàn)升高又降低的情況,可能是由于DC-CIK在殺傷腫瘤時(shí),腫瘤凋亡釋放出大量腫瘤相關(guān)蛋白,使腫瘤標(biāo)志物升高,隨后隨著殺傷的不斷進(jìn)行,這些物質(zhì)作為代謝物被清除體內(nèi),腫瘤標(biāo)志物隨之下降。

免疫功能方面,本研究結(jié)果顯示,治療后兩組CD4+、CD4+/CD8+、NK表達(dá)均較治療前升高,且實(shí)驗(yàn)組高于對(duì)照組,差異具有統(tǒng)計(jì)學(xué)意義(P<0.05);治療后兩組CD8+表達(dá)均較治療前下降,且實(shí)驗(yàn)組低于對(duì)照組,差異具有統(tǒng)計(jì)學(xué)意義(P<0.05)。細(xì)胞因子IL-4、IL-6、IL-10治療前后無明顯變化,IL-2、TNF-α、IFN-γ也隨療程持續(xù)升高,表明DC-CIK通過增加CD4+、CD4+/CD8+、NK的表達(dá)調(diào)節(jié)機(jī)體免疫功能。IL-2主要由活化T細(xì)胞產(chǎn)生,對(duì)機(jī)體的免疫應(yīng)答和抗病毒感染等有重要作用。TNF-α具有特異性殺傷腫瘤細(xì)胞表面不損傷正常細(xì)胞的功能。IFN-γ由活化T細(xì)胞、自然殺傷細(xì)胞及NKT細(xì)胞產(chǎn)生,具有抗病毒、免疫調(diào)節(jié)劑、抗腫瘤的特性。當(dāng)NKT細(xì)胞的表達(dá)持續(xù)升高時(shí), IL-2、TNF-α、IFN-γ也隨之升高。有研究表明 IL-2、TNF-α和IFN-γ 能增強(qiáng) NK細(xì)胞及 T 細(xì)胞的活性,既能抑制腫瘤細(xì)胞增殖又能直接殺傷腫瘤細(xì)胞,并且能減少腫瘤的復(fù)發(fā)和轉(zhuǎn)移[13,16-18,]。多療程的治療就相當(dāng)于形成了一個(gè)正反饋調(diào)節(jié),不斷的提升免疫力,殺傷腫瘤細(xì)胞,調(diào)節(jié)腫瘤患者的免疫功能,并且多療程DC-CIK改善程度更大。兩組在治療過程中均未發(fā)現(xiàn)有不良反應(yīng),說明DC-CIK治療安全性較高。

綜上所述,多療程的DC-CIK治療可提升肺癌患者的免疫功能、殺傷腫瘤細(xì)胞,對(duì)后續(xù)進(jìn)行放化療、腫瘤靶向治療等具有很好的輔助作用。
