摘要
目的:探讨血小板衍生生长因子-D(PDGF-D)mRNA在胃癌组织中的表达及其与临床病理特征的关系。方法:用RT-PCR方法检测58例胃癌及相对应的癌旁标本中PDGF-D的表达,分析其与临床病理特征的关系。结果:PDGF-D在胃癌组织中表达率(98.28%)明显高于癌旁组织(87.93%)(P<0.05),胃癌组织中PDGF-D表达水平(0.703±0.336)明显高于癌旁组织(0.465±0.208)(P<0.05)。PDGF-DmRNA的表达水平与胃癌的淋巴结及远处转移和复发及无瘤生存期长短有关(P<0.05),与其它临床特征无关(P>0.05)。结论:PDGF-D在胃癌的发生、发展和转移、复发中可能起着重要的作用。检测PDGF-D的表达可作为预测胃癌转移和复发的有意义指标。
Objective: To investigate the correlation between mRNA expression of PDGF-D and clinicopathological features in gastric cancer. Methods: The reverse transcription-polymerase chain reaction(RT-PCR)technique was used to examine mRNA expression of PDGF-D and in 58 pair specimens of gastric carcinoma and tissues adjacent carcinoma. Results: The positive rates of PDGF-D mRNA in gastric cancer tissues(98.28%) were significantly higher than in tissues adjacent carcinoma(87.93%) respectively(P0.05).Then the levels of expression in gastric cancer tissues(0.703±0.336)were significantly higher than in tissues adjacent carcinoma(0.465±0.208) respectively(P0.05) .PDGF-D expression was correlated with lymph node metastasis and prognosis(P0.05).While no correlation was found between PDGF-D and other clinical significance of gastric carcinoma(P0.05). Conclusion: PDGF-D may play a crucial role in carcinogenesis,development,metastasis and relapse of gastric cancer.It can be used as prognostic marker of gastric cancer in clinical practice.
