胰腺癌不易早期诊断、难于早期治疗、预后不良，其中主要原因是对胰腺癌发生发展的机理知之甚少。为此，我们从1984年以来，在以往临床病理研究的基础上，着重进行了人胰腺癌分子生物学及细胞生物学特性的研究。首先，我们建成了数株中国人胰腺癌细胞系（4株已建成，另3株正在
Pancreatic cancer is not easy to diagnose early, difficult to treat early and has a poor prognosis. The main reason is that the mechanism of pancreatic cancer is poorly understood. For this reason, we have carried out studies on molecular biology and cell biology of human pancreatic cancer on the basis of past clinical pathological studies since 1984. First, we built several strains of Chinese pancreatic cancer cell lines (4 strains have been constructed and 3 strains are
