细胞凋亡是由基因控制的细胞主动死亡，参与调节机体细胞增殖与死亡间的平衡稳定。肿瘤不仅存在细胞异常增殖，同时存在细胞凋亡异常，且具有长期共存的特点 [1]。我们通过观察胃癌及其癌前病变组织细胞凋亡的情况，探讨细胞凋亡与胃癌发生发展的关系。 一、材料与方法 1
Apoptosis is a genetically controlled cell that actively participates in the regulation of the balance between cell proliferation and death. Tumors not only exist abnormal cell proliferation, there is abnormal apoptosis, and has the characteristics of long-term coexistence [1]. By observing the apoptosis of gastric cancer and its precancerous lesions, we explored the relationship between apoptosis and the occurrence and development of gastric cancer.
