摘　　要：胰腺癌仍是肿瘤学目前难以攻克和富有挑战性的难题,放射性粒子由于其物理及生物学的特点,治疗胰腺癌具有独特的优势。放射性粒子离体照射模型的设计和建立,为研究粒子辐射生物效应提供了有效和重要的方法,并已广泛用于放射生物学和剂量学的研究。临床研究显示,胰腺癌组织间近距离放射治疗能够提高局部控制率、减轻疼痛、改善患者生活质量和提高生存率,是治疗胰腺癌的一种重要方法。Cancer of the pancreas remains a formidable challenge in oncology presently. It has unique advantages to treat pancreatic cancer by radioactive seeds because it has many physical and biological characteristics. The seed irradiator designed and built is very efficient and effective and has already been used extensively in radiobiological experiments and the accuracy of dosimetry. From reported clinical results, interstitial brachytherapy for pancreatic cancer can control tumor, relieve pain, improve quality of life and survival. It is an important modality in the treatment of pancreatic cancer.
