随着现代医学的进步,肿瘤患者的生存时间明显延长,发生腹腔淋巴结转移变得常见,由于胃肠道对于放射较为敏感,大的转移性淋巴结中心乏氧细胞及照射体积增大,其毒副反应也使许多患者难以耐受,影响治疗的顺利进行。肿瘤热疗是安全有效的方法,能杀灭乏氧细胞,与放疗有协同作用,故 With the progress of modern medicine, the survival time of tumor patients is obviously prolonged, and the occurrence of celiac lymph node metastasis has become common. Due to the sensitivity of gastrointestinal tract to radiation, the hypoxic cells in the center of large metastatic lymph nodes and the irradiation volume increase. The reaction also makes many patients intolerable, affecting the smooth progress of the treatment. Tumor hyperthermia is a safe and effective method to kill hypoxic cells and has a synergistic effect with radiotherapy
