应用石蜡包埋的Ca761－YP8／L小鼠移植性乳腺癌组织制备的瘤苗，对荷瘤（Ca761－FP8／L）的615近交系小鼠的治疗作用进行了研究，结果显示：经PETV治疗后小鼠的存活期明显延长，肿瘤的重量明显小于对照组，肺转移率也较对照组降低，应用PETV配合选择性去除Ts细胞的小剂量CTX和增强免疫应答反应的细胞因子INFa－2b可进一步提高疗效。作者认为，PICFV应用范围广，可长期保存抗原等优点，值得深入研究。 The therapeutic effect of tumor-bearing (Ca761-FP8 / L) 615 inbred mice was studied using paraffin-embedded tumor-bearing Ca761-YP8 / L mice transplanted with breast cancer tissue. The results showed that PETV treatment significantly prolonged survival of mice, the tumor weight was significantly smaller than the control group, lung metastasis rate was also lower than the control group, the application of PETV with selective removal of Ts cells in small doses of CTX and enhance the immune response to cytokines IFN- 2b can further improve the efficacy. The authors believe that, PICFV wide range of applications, long-term preservation of antigens and other advantages, it is worth further study.
