作者对62例肺癌脑转移以~(60)Coγ射线行放射治疗,照射方法为左右相对二野照射全脑,照射总剂量预定在40Gy以上,每日照射一次,一周照射5次,每次照射剂量自50～70cGy开始,在一周内每照射剂量渐增至150～200cGy。病例以腺癌及小细胞癌居多,生存3.3个月者占50%,生存6个月占33.8%,生存1年者占8.9%。照射前有神经症状者54例,照射后完全消失者12例,占22.2%,减 The authors treated 62 patients with lung cancer brain metastases with ~(60)Co gamma-rays. The irradiation method was to irradiate right and left relative fields to the whole brain. The total irradiation dose was scheduled to be above 40 Gy, once a day, once a week, and 5 times per week. The dosage starts from 50 to 70 cGy and gradually increases to 150 to 200 cGy per irradiation dose within one week. Cases were mostly adenocarcinoma and small cell carcinoma. The survival rate was 3.3% for 5 months, 33.8% for 6 months, and 8.9% for 1 year. There were 54 patients with neurological symptoms before irradiation, 12 patients completely disappeared after irradiation, accounting for 22.2%.
