Clinical efficacy and safety of tumor-specific individualized multi-target DC-CIK in the treatment of advanced non-small cell lung cancer / 中国肿瘤生物治疗杂志

@#[摘 要] 目的：评价肿瘤特异性个体化多靶点树突状细胞-细胞因子诱导的杀伤细胞（DC-CIK）治疗晚期非小细胞肺癌（NSCLC）患者的临床疗效和安全性。方法：回顾性分析2019年10月1日至2022年10月31日东部战区总医院生物治疗科行肿瘤特异性个体化多靶点DC-CIK治疗晚期NSCLC患者的临床资料。统计NSCLC患者的临床疗效和不良反应，分析治疗前后血清中肿瘤标志物的变化，FCM检测患者治疗前后的淋巴细胞亚群和各种细胞因子的表达情况，用质谱仪检测治疗前后靶点的变化。结果: 共入组52例晚期NSCLC患者，其中女性21例、男性31例；年龄32~71岁，平均年龄（50.97±10.72）岁，中位年龄47.5岁。经DC-CIK治疗后，CR 0例，PR 0例，SD 27例，PD 25例。与治疗前比较，DC-CIK治疗后：（1）CEA和CYFRA21-1水平无显著改变，CA125水平显著低于治疗前（P<0.01）；（2）治疗后患者淋巴细胞亚群无显著变化；（3）治疗后患者外周血IL-2、IL-4、IFN-γ和TNF-α水平显著升高（均P<0.01），IL-6、IL-10及IL-17水平无明显变化；（4）治疗后靶点数下降明显。DC-CIK治疗过程中无严重不良反应发生。结论: 晚期NSCLC患者行肿瘤特异性个体化多靶点自体DC-CIK治疗是安全的，能使患者产生抗肿瘤免疫反应并得到一定的临床获益。

Short-term treatment efficacy of NK cells for ovarian cancer ascites / 中国肿瘤生物治疗杂志

@#[Abstract] Objective: To investigate the short-term clinical efficacy and safety of intraperitoneal perfusion of natural killer (NK) cells in the treatment of ovarian cancer with ascites. Methods: The clinical data of 15 ovarian cancer patients with ascites effusion, who received NK cell perfusion in the Qinhuai Medical District of the General Hospital of Eastern Theater Command from November 2016 to January 2019, were analyzed. The peripheral blood was collected to isolate the peripheral blood mononuclear cells, and to further obtain the NK cells after culture. NK cell suspension was intraperitoneally perfused into the abdominal cavity (no less than 2×109 cells/ time). The volume of peritoneal effusion, the level of serum tumor marker CA-125, the level of serum cytokines IL-2, INF-γ and TNF-α as well as the changes in peripheral blood lymphocyte subsets were detected before and after the treatment; Moreover, the clinical efficacy and adverse reactions were observed. Results: The effective rate of intraperitoneal perfusion of NK cells was 66.7%, and there were no obvious treatment-related adverse reactions. Compared with before treatment, the serum tumor marker CA-125 level significantly decreased after treatment (P<0.05), and the levels of IL-15, IFN-γ and TNF-α increased significantly (P<0.05 or P<0.01), while there was no significant changes in peripheral blood lymphocyte subsets (all P>0.05). Conclusion: Intraperitoneal infusion of NK cells in the treatment of ovarian cancer associated peritoneal effusion has a good short-term clinical efficacy with little adverse reactions, which is a promising method for the treatment of cancerous peritoneal effusion.
