本文叙述~(60)钴移动条放射治疗原发性肝癌的治疗方法。有效剂量为,4,000rad以上,低于3,000rad者疗效差。全肝照射39例,次全肝照射11例。生存期平均8.2月,中位7月,一年以上16例(32％),二年者4例(18％),放疗后肿瘤缩小者占72％,肝痛减轻或消失者占60％。放射反应有恶心16例,食欲减退12例,白血球下降3,000以下7例及放射性肝炎5例。移动条放疗具有照射范围大,剂量均匀,生物效应高,放射反应轻等优点。
This article describes the treatment of ~(60) cobalt strip radiation therapy for primary liver cancer. The effective dose is 4,000rad or more, and less than 3,000rad is not effective. There were 39 cases of whole liver irradiation and 11 cases of sub-entry liver irradiation. The average survival time was 8.2 months, and the median time was July, 16 cases (32%) were more than one year, 4 cases (18%) were two years, 72% were reduced after radiotherapy, and 60% were relieved or disappeared. There were 16 cases of nausea, 12 cases of loss of appetite, 7 cases of white blood cells falling below 3,000, and 5 cases of radioactive hepatitis. Mobile bar radiotherapy has the advantages of large irradiation range, uniform dose, high biological effect, and light radiation response.
