[摘要] 目的 观察CIK细胞免疫治疗对转移性肾癌患者免疫功能的影响。方法 选取2010~2012年收治的转移性肾癌患者,在常规治疗措施的基础上联合应用CIK细胞免疫方法进行临床治疗,治疗3个疗程后,监测治疗前后CD3+、CD4+、CD8+、CD4+/CD8+比值等免疫功能指标,进行统计学分析。结果 治疗后患者外周血中CD3+、CD4+、CD8+、CD4+/CD8+水平优于治疗前(P<0.05)。结论 采用CIK细胞免疫治疗能有效提高转移性肾癌患者的免疫功能。

[Abstract] Objective To study the effect of cytokine-induced killer(CIK) cells immunotherapy on immunological function of patients with metastatic renal cell carcinoma. Methods A total of 70 patients with metastatic renal cell carcinoma were randomly divided into 2 groups, 35 cases of the treatment group were added with CIK cells, while the control group was given IL-2 and IFN-α, detected the immunological function of 70 cases including the levels of CD3+, CD4+, CD8+T cells, ratio of CD4+/CD8+, one week before therapy of CIK cells and one month week after treatment. Results The levels of CD3+、CD4+ cells, ratio of CD4+/CD8+ in peripheral blood of patients with renal cancer of two groups were much higher than those before therapy(P<0.05), the levels CD8+ was lower after treatment, there were significant changes (P<0.05). Conclusion CIK cells immunotherapy can enhance the immunological function of patients with metastatic renal cell carcinoma.

CIK细胞免疫治疗被认为是新一代抗肿瘤过继细胞免疫治疗首选方案。研究表明,CIK细胞在肾癌治疗中显示了良好的抗肿瘤作用[1]。肾癌具有多药物耐药基因,对化疗、放疗不敏感,生物免疫治疗有一定疗效。为了寻找治疗肾癌更为有效的方法,本研究采用CIK细胞免疫治疗转移性肾细胞癌,观察治疗前后患者免疫功能指标的变化,了解其对转移性肾细胞癌患者免疫功能的影响。

1资料与方法

1.1一般资料

70例转移性肾细胞癌患者为河南省中医院、河南省肿瘤医院、郑州市中心医院2010年1月~2012年2月住院观察病例,均经免疫组化病理证实。男48例,女 22例;年龄38~73岁,平均56岁。按入院先后均分为两组,其中肺转移26例,骨转移21例,肝转移8例,脑转移9例,其他部位转移6例。70例患者ECOG分级≥Ⅲ级,预计生存期≥3个月。两组在年龄、性别、病程、病理类型等方面均无显著差异(P>0.05),具有可比性。

1.2方法

1.2.1治疗方案对照组采用常规治疗 IL-2(5×106 U/m2,d 1、d 3、d 5)和IFN-α(3×106 U/m2,d 2、d 4、d 6),连用4周,停药2周,每6周为1个治疗周期。治疗组在常规治疗一个周期后采用CIK治疗,患者至少接受3个疗程CIK治疗。
