因为在正常状态下,胰腺细胞的增殖率非常低,进入细胞周期被认为是肿瘤发生的初始事件。所谓的检查点监测细胞周期进程,并保证整个基因组的适当复制。失去一个或多个检查点会导致随后的基因改变积累,最终导致癌症。癌细胞具有生长不受限制、侵袭邻近组织和转移的特点。所有这些特征都可以用遗传变化和这些变化的功能后果来解释。原癌基因K-Ras的激活和肿瘤抑制基因INK4a、p53和SMAD4的失活是胰腺癌的特征。胰腺癌的进展模型提示胰腺上皮内瘤变是癌前病变。一种首选的遗传途径已经开始进化。特定基因的种系突变是导致家族性胰腺癌易感性的原因。
Because in the normal state, cells of the pancreas show a very low rate of proliferation, entering the cell cycle is assumed to be the initial event during tumorigenesis. So-called checkpoints monitor cell cycle progression and guarantee the proper duplication of the entire genome. Loss of one or more checkpoints causes subsequent accumulation of genetic alterations which finally results in cancer. Cancer cells are characterized by unrestricted growth, invasion of adjacent tissue and metastasis. All of these features can be explained in terms of genetic changes and the functional consequence of these changes. Activation of the proto-oncogene K-Ras and inactivation of the tumour suppressor gene loci INK4a, p53 and SMAD4 are characteristic for pancreatic cancer. The progression model of pancreatic cancer proposes that pancreatic intraepithelia neoplasia is the pre-cancerous lesion. A preferred genetic pathway has started to evolve. Germ-line mutations in specific genes are responsible for cases in which there is a familial predisposition to pancreatic cancer.
