[美联社加利福尼亚州拉霍亚1980年12月3日电]加利福尼亚大学医学院的研究人员称,他们研制出一种装置可以治疗在过去不能达到的部位的肺肿瘤。一位发言人说,将放射性粒子用针头植入8名病人。此种治疗仅用于已经癌瘤手术而未能切除此种恶性病变的病人,或不再能接受外部放射治疗的病人。 [AP, La Jolla, California, December 3, 1980] Researchers at the University of California Medical School say they have developed a device that can treat lung tumors that have not been reached in the past. A spokesperson said that radioactive particles were implanted with needles into 8 patients. This treatment is only used for patients who have undergone cancer surgery but have not been able to remove such malignant lesions, or who are no longer able to receive external radiation therapy.
