胸腔内热物理疗法（以下简称热疗）是作者根据热能杀伤肿瘤细胞，且其热敏感性高于正常细胞2倍的原理，研究设计的一种只对胸水、胸膜甚或胸腔内肿瘤细胞进行直接热杀伤的治疗方法，该方法利用提高热温度和热作用时间可成倍杀伤的双相潜力因素，以达到控制胸水的目的。技术要点 Intrathoracic thermal physiotherapy (hereinafter referred to as hyperthermia) is based on the principle that the authors kill tumor cells based on heat, and its thermal sensitivity is two times higher than that of normal cells. The study design a direct heat only to pleural effusion, pleural or even intrathoracic tumor cells. The killing treatment method utilizes the biphasic potential factors that increase the thermal temperature and the thermal action time to double the killing so as to achieve the purpose of controlling the pleural effusion.
