我院自1984年3月至1988年10月采用液氮冷冻手术加放疗肺癌32例,其中原发他肺癌28例(Ⅰ期2例、Ⅱ期4例、Ⅲ期22例)。肺部转移性癌4例。冷冻摘除肿瘤术后一月开始放疗,对胸水较多或转移性肺癌先作全胸移动条野照射DT20～25Gy,再作局部加量照射15～20Gy。其余病例照射原发灶瘤床和纵隔DT50～60Gy。 In our hospital from March 1984 to October 1988, 32 cases of lung cancer were treated with liquid nitrogen cryosurgery and radiotherapy, of which 28 were primary lung cancers (2 in stage I, 4 in stage II, and 22 in stage III). Metastatic lung cancer in 4 cases. After cryoablation of the tumor, radiotherapy began in one month and thoracic fluids or metastatic lung cancers were first irradiated with DT20-25Gy, and local irradiation was performed for 15-20Gy. The rest of the patients were exposed to the primary tumor bed and mediastinal DT50 ~ 60Gy.
