采用经皮肺穿刺后装~(192)Ir组织间近距离照射治疗肺癌患者49例。治疗后1～4周复查,患者症状均明显好转,X线片示3例肿块消失,14例中央型、32例周围型肿块缩小约50％,有效率达99％以上。随访6～18个月,50％的患者健康生存1年以上。认为该法操作简便,损伤小,疗效显著,疗程短,为治疗肺癌的一种新方法。 49 patients with lung cancer were treated with 192 Ir irradiation after percutaneous lung puncture. After 1 to 4 weeks of treatment, the symptoms of the patients were significantly improved. The X-ray films showed that the masses disappeared in 3 cases, and 14 cases of central type and 32 cases of peripheral type masses were reduced by about 50%, and the effective rate was over 99%. After 6 to 18 months of follow-up, 50% of patients survived for more than 1 year. It is believed that this method is simple, easy to operate, with little injury, significant curative effect and short course of treatment. It is a new method for treating lung cancer.
