胰腺癌的早期诊断不易,切除率不高,治疗的结果令人失望,近年来各种手术方式的改进以及化疗、放疗方案等综合措施的引进,手术并发症和死亡率有所降低,但5年生存率仍提高不多[1] 。随着免疫和分子生物学在肿瘤的发生、发展和转移机制研究的不断深入,为胰腺癌的治疗提供了新的治疗 Early diagnosis of pancreatic cancer is not easy, the resection rate is not high, the results of the treatment is disappointing. In recent years, various surgical modalities and the introduction of comprehensive measures such as chemotherapy and radiotherapy have reduced the complications and death rate. However, Annual survival rate is still not much improved [1]. With the development of immune and molecular biology in the pathogenesis, development and metastasis mechanisms continue to provide new treatments for the treatment of pancreatic cancer
