[摘要] 目的：评价树突状细胞（DC）疫苗联合细胞因子诱导的杀伤（CIK）细胞治疗转移性肾癌的长期临床疗效及随访观察。方法：选择2011 年1 月至2013 年12 月于中国人民解放军总医院第五医学中心造血干细胞移植科接受DC疫苗联合CIK细胞治疗的29 例转移性肾癌患者，其中男性24 例、女性5 例，中位年龄55 岁（32～81 岁）。一线治疗12 例，分子靶向药物或细胞因子治疗进展后二线治疗6 例，三线及以上治疗11 例（包括二次手术治疗、细胞因子治疗和多线分子靶向药物治疗）。通过基因转染技术获得成熟的DC疫苗，体外细胞培养技术获得CIK细胞，经淋巴引流区及静脉输注方式按疗程回输患者体内，评价其长期临床疗效及总体生存率。结果：29 例患者中位随访时间5 年（1～7 年）。治疗疗程≥2（2～23 个疗程）。疗效评价：完全缓解1 例（3.4%），部分缓解9 例(31%)，疾病稳定13 例(44.8%)，疾病进展6 例(20.7%)。客观反应率34.4%，疾病控制率79.2%。疾病稳定1年以上19 例（65.5%）。1、3、5 年生存率分别为93.1%(27/29)、65.5%（20/29）和51.7%（15/29）。中位无进展生存期及中位生存期均未达到。治疗期间均未观察到3 级以上不良反应发生。结论：DC疫苗联合CIK细胞治疗转移性肾细胞癌疗效肯定，可获得良好的疾病控制率及长期生存，安全性可控，延长了晚期肾癌患者的生存期。

[Abstract] Objective: To evaluate the long-term clinical efficacy and follow-up of dendritic cell (DC) vaccines in combination with cytokine-induced killer cell (CIK) treatment in metastatic renal cell carcinoma. Methods: From January 2011 to December 2013, 29 patients with metastatic renal cell carcinoma (pathologically confirmed as renal clear cell carcinoma) were treated by DC vaccines-CIK at the Department of Hematopoietic Stem Cell Transplantation, the Fifth Medical Center of Chinese PLA General Hospital. The 29 patients included 24 male and 5 female, with a median age of 57(32-81) years old. Mature DC vaccine was obtained by gene transfection technology and CIK cells were obtained by in vitro culture; and DC vaccine-CIK was infused back to patients through lymphatic drainage area and vein by each course. Twelve patients received first line treatment, 6 patients received second line treatment after the disease progression by targeted drug therapy or cytokine therapy, and 11 patients received third-linetreatment or above. The long-term clinical efficacy and overall survival rate were evaluated. Results: The median follow-up time was 5 (1-7) years. Treatment cycle was over 2 (2-23) cycles. One case (3.4%) achieved complete remission, 9 cases (31%) achieved partial responses, 13 cases (44.8%) demonstrated stable disease over 3 months and 6 patients (20.7%) developed progressive disease. The objective response rate was 34.4%,and the disease control rate was 79.2%. Stable disease for more than one year realized in 19 cases (65.5%). The 1-, 3- and 5-year survival rates were 93.1% (27/29), 65.5% (20/29) and 51.7% (15 / 29), respectively. Neither the median progression-free survival (PFS) nor the median survival time was achieved. No adverse reactions above grade 3 were observed during treatment. Conclusion: DC vaccines-CIK therapy for the treatment of metastatic renal cell carcinoma is affirmative; it achieved good disease control and long-term survival with controllable safety, and prolonged the survival time for advanced renal cell carcinoma patients.
