食管癌和癌旁组织细胞凋亡与患者生存期的关系

The relationship between the apoptosis of esophageal carcinoma tissue and its adjacent tissue with the survival time of patients with esophageal carcinoma

目的 通过检测食管癌、癌旁组织细胞凋亡率，探讨食管癌组织细胞凋亡与患者生存期的关系。方法 收集68例手术食管癌患者的食管癌组织、癌旁组织和28例正常食管黏膜组织标本，应用流式细胞技术检测细胞凋亡率，并对63例患者进行1、3年生存期随访。结果细胞凋亡率在正常食管黏膜组织中为（12．78±1．32）％，癌旁组织为（7．79±1．48）％，食管癌组织为（4．16±2．06）％，各组织间比较差异均有统计学意义（P〈0．05）。随访结果显示，生存期1年60例、生存期3年35例；生存期1年患者食管癌组织和癌旁组织细胞凋亡率分别为（3．45±1．51）％和（3．96±0．94）％；生存期3年患者食管癌组织和癌旁组织细胞凋亡率分别为（3．90±2．53）％和（7．89±2．27）％。生存期1年和3年患者癌旁组织细胞凋亡率比较差异有统计学意义（P〈0．05），而食管癌组织细胞凋亡率比较差异无统计学意义。结论 食管癌在发生和发展过程中癌细胞也存在凋亡逃逸现象；食管癌组织细胞凋亡与患者生存期有一定的关系。癌旁组织细胞凋亡程度比食管癌组织中的细胞凋亡现象在食管癌的发生及预后评估中更为重要。

Objective To explore the relationship between the apoptosis of esophageal carcinoma tissue and its adjacent tissues with the survival time of patients with esophageal carcinoma by examining the apoptosis in esophageal carcinoma tissue and its adjacent tissues. Methods FCM was performed to detect the rates of apoptosis in 68 cases of esophageal carcinoma and their adjacent tissues and 28 cases of normal esophageal mucosae tissue. Sixty-three patients with esophageal carcinoma had been followed up and noted the survival time of every patient from the operated day to the deadline. Results The rate of apoptosis was the highest in the normal esophageal mucosae tissue （ 12.78 ±1.32 ）%, （ 7.79 ± 1.48 ）% in adjacent tissue, and（ 4.16 ± 2.06 ）% in esophageal carcinoma tissue, respectively. To follow the survival time after operation of 63 cases with esophageal carcinoma showed 60 cases in one year survival time and 35 cases in three years survival time. The rate of apoptosis in the esophageal carcinoma and its adjacent tissues was （ 3.45 ± 1.51 ）% and （ 3.96 ± 0.94 }% in the patients of one year survival time, （ 3.90 ± 2.53 ）% and （ 7.89 ± 2.27 ）% in the patients of three years survival time, respectively, P 〈 0.05. Conclusions There is the phenomenon of apoptosis -escape in the esophageal carcinogenesis. There is close relationship between the apoptosis of esophageal carcinoma tissue and the survival time after operation. The apoptosis in the adjacent tissue is more important than that in the esophageal carcinoma tissue for evaluating the survival time after operation of patients with esophageal carcinoma.
