冷冻手术具有两个显著特点:能治疗用其它手段难以治疗的恶性肿瘤,可能还有肿瘤特异性免疫治疗作用。联合应用包括冷冻手术在内的综合治疗,为治疗癌症提供了一种新的手段。动物实验研究表明,冷冻手术治疗能增强免疫反应。在大鼠实验肿瘤中,单用冷冻手术治疗,不能诱发与人类相似的冷冻免疫反应,但在冷冻手术的同时辅助应用适当的免疫增强 Cryosurgery has two distinctive features: it can treat malignant tumors that are difficult to treat with other means, and may also have tumor-specific immunotherapy. The combined use of comprehensive treatment including cryosurgery provides a new approach to the treatment of cancer. Animal experimental studies have shown that cryosurgery can enhance the immune response. In rat experimental tumors, cryosurgery alone does not induce a frozen immune response similar to humans, but assists with appropriate immune enhancement while cryosurgery
