恶性肿瘤基因治疗的临床研究已有10余年,但疗效尚未确定。治疗策略也不下十余种,但何种策略为佳尚无定论。目前采用的策略多数为单一基因治疗,而肿瘤的发生可能涉及多种基因及多种因素,发病过程也是多步骤的。本研究建立一种细胞因子基因工程人肝癌和胃癌细胞“瘤苗”,用于经手术切除的肝癌或胃癌患者,消灭微小残存癌细胞, Clinical studies of gene therapy of malignant tumors for more than 10 years, but the efficacy has not yet been determined. Treatment strategy is not less than a dozen, but what kind of strategy is good is not conclusive. At present, most of the strategies adopted are single gene therapy, and the occurrence of tumors may involve multiple genes and multiple factors, and the pathogenesis is also multi-step. This study established a cytokine genetically engineered human hepatoma and gastric cancer cells “tumor vaccine” for the resection of liver cancer or gastric cancer patients, the elimination of small residual cancer cells,
