在常规染色的组织学切片中，应用光学显微镜检测２９例子宫内膜腺癌的细胞凋亡情况，观察凋亡指数与肿瘤分级之间的关系。Ⅰ级５例，Ⅱ级１８例和Ⅲ级６例腺癌的平均凋亡指数分别为１．９％、２．８９％和３．１５％。分析表明，凋亡指数在Ⅰ级与Ⅱ级之间和Ⅱ级与Ⅲ级之间的差异没有统计学意义，但Ⅰ级与Ⅲ级之间有非常显著性差异（Ｐ＜０．０１）。
In routine stained histological sections, the apoptosis of 29 cases of endometrial adenocarcinoma was detected by light microscopy, and the relationship between apoptosis index and tumor grade was observed. The average apoptotic index of 5 cases with grade I, 18 cases with grade II and 6 cases with grade III were 1.9%, 2.89%, and 3.15%, respectively. The analysis showed that there was no significant difference in the apoptotic index between grade I and grade II and between grade II and grade III, but there was a significant difference between grade I and grade III (P<0.01).
