摘要
目的:探讨血管内皮生长因子C(VEGF-C)和环氧合酶-2(COX-2)的表达在胃癌的发生、发展及预后的临床意义。方法:采用S-P免疫组织化学方法,检测VEGF-C和COX-2在胃镜活检的正常胃黏膜(n=17)、浅表性胃炎(n=19)、萎缩性胃炎/肠化生(n=22)、胃黏膜不典型性增生(n=23)和胃癌患者1期(n=18),2期(n=24),3期(n=22),4期(n=18)的胃组织。结果:胃癌组织中的VEGF-C和COX-2的表达阳性率明显高于非胃癌组织,正常胃黏膜、浅表性胃炎、萎缩性胃炎/肠化生、胃黏膜不典型性增生至胃癌逐级之间的差异有统计学意义(P<0.05);在3及4期胃癌中的表达阳性率明显高于1及2期(P<0.05);VEGF和COX-2的表达具有显著相关性(P<0.01)。结论:VEGF-C和COX-2的共同表达在胃癌的发生发展可能起重要作用,联合检测VEGF-C和COX-2对胃癌的早期诊断、临床防治及预后可能具有重要临床价值。
Objective: To cance in occurrence, development explore the expression of VEGF and prognosis of gastric cancer. C and COX 2 and their clinical Methods: Expressions of VEGF ignifi-C and COX-2 were determined by S-P immunohistochemical staining analysis in stomach tissue of normal gastric mucosa(n=17),atrophic gastritis(n=19) ,superficial gastritis(and/or atrophic gastritis)(n=22),gastric mucosa not typical hyperplasia(n=23) and gastric cancer Ⅰ period (n=lS), gastric cancerⅡ period(n= 24,)gastric cancer Ⅲ period (n = 22) and gastric cancer IV period(n = 18). Results: The positive rates of VEGF-C and COX-2 were significantly higher in gastric cancer tissue than in tissue without gastric cancer. There were significant 'difference in expressions of VEGF-C and COX 2 among normal gastric mucosa,atrophic gastritis, superficial gastritis ( and/or atrophic gastritis), atypical hyperplasia gastric mucosa and gastric cancer tissue (P〈0.05). The positive rate was significantly higher in stage 3 and 4 than stage 1 and 2 (P〈0.01). The expression of VEGF C was significantly correlated with expression of COX-2 (P〈 0.01). Conclusions: Co-expression of VEGF-C and COX-2 may play an important role in the occurrence and development of gastric cancer. Combined detection of VEGF-C and COX-2 is valuable in early diagno sis, prevention, treatment and prognosis of gastric cancer
