细胞凋亡有其独特的形态学特点和生物学特点．肿瘤细胞也存在自发的细胞凋亡，只不过是肿瘤细胞凋亡与增殖的比例发生失调．肿瘤细胞存在的自发细胞凋亡受到药物、放射线、细胞因子、激素、基因编码等因素的影响［１］．细胞凋亡已成为肿瘤治疗的新途径．胃癌是消化道常见... Apoptosis has its unique morphological and biological characteristics. The tumor cells also have spontaneous apoptosis, but the ratio of apoptosis and proliferation of tumor cells is disordered. The spontaneous apoptosis of tumor cells is affected by drugs, radiation, cytokines, hormones, gene coding and other factors [1]. Apoptosis has become a new approach to cancer therapy.
