胰腺癌由于恶性程度高、手术切除率低、早期诊断困难 ,治疗的效果不尽人意。近年来 ,随着对肿瘤的发生、发展和转移机制认识的不断深入 ,尤其是肿瘤分子生物学与免疫学的进展 ,关于肿瘤相关的免疫调节与应答、癌变、转移以及癌基因和抑癌基因之间的作用机制的进一步了解 ,许多 Due to the high degree of malignant pancreatic cancer, surgical resection rate is low, early diagnosis is difficult, the effect of treatment less than satisfactory. In recent years, with the deepening understanding of the mechanism of tumorigenesis, development and metastasis, especially the progress of tumor molecular biology and immunology, the related immunoregulation and response, carcinogenesis, metastasis and oncogenes and tumor suppressor genes There is much more to be learned about the mechanism of action between
