【摘要】 早在20世纪初人们就开始将放射性粒子用于胰腺癌治疗,但由于使用的放射性粒子如226Ra针、198Au、192Ir和222Rn等放射生物学或放射物理学方面的局限性,植入技术和植入计划系统的不健全,使得粒子植入治疗胰腺癌发展缓慢。20世纪60年代末期随着125I粒子临床应用,放射性核素放射生物学及放射物理学特性的深入研究,三维治疗计划系统的飞速发展,术中超声技术的使用,使得粒子植入治疗胰腺癌再度回归。更多还原

【Abstract】 Radioactive seeds have been used to treat pancreatic carcinoma in the early twenty cen-tries. Advances in the therapy of pancreatic carcinoma with radioactive seeds is slow because of the limitations of radiobiology and radiophysics , unsoundness of implantation technique and implantation plan system. As the radioactive seeds 125I have been used since the late 1960s and radiobiology and radiophysics of radionucide has been studied profoundly , fast development of three-dimensional treatment plan system , useness of ultrasonically guided percutaneous implantation therapy for pancreatic carcinoma with radioactive seeds rise again.更多还原
