- W2348872153 abstract "Objective To understand the situation of epithelial- mesenchymal transitions(EMT) in non- small cell lung cancer(NSCLC) and investigate the pathological and clinical significance of it. Methods The immunohistochemistry was used to detect protein expressions of E- cadherin and vimentin in 143 samples of NSCLC and 44 samples of bronchus epithelial cells surrounding tumor. The SPSS17. 0 statistic software was used to analyze the correlation between the protein expressions and the clinic- pathological agents of the patients with NSCLC. Results The positive expression rate of E- cadherin protein in the tumor cells of NSCLC was statistically lower than that in bronchus epithelial cells surrounding tumor(52. 4% vs. 70. 5%,P 0. 05),and there was significant correlation between tumor cells and their corresponding bronchus epithelial cells surrounding tumor(r = 0. 539,P 0. 05). Furthermore,the rate in the poorly differentiated adenocarcinoma(34. 4%) was statistically lower than that in the well- moderately differentiated adenocarcinoma(61. 7%)(P 0. 05),and the rate in the male patients(43. 2%) was statistically lower than that in the female(64. 5%)(P 0. 05). However,the expression was not significantly related to patients' age,smoking status,tumor histological type and lymph node metastasis(P 0. 05). The positive expression rate of vimentin protein in the tumor cells of NSCLC was statistically higher than that in bronchus epithelial cells surrounding tumor(36. 4% vs 20. 5%,P 0. 05),and there was significant correlation between tumor cells and their corresponding bronchus epithelial cells surrounding tumor(r = 0. 814,P 0. 05). The rate in the poorly differentiated adenocarcinoma(62. 5%) was statistically higher than that in the well- moderately differentiated adenocarcinoma(30. 0%)(P 0. 05). The expression was not significantly related to patients' gender,age,smoking status,tumor histological type and lymph node metastasis(P 0. 05). The expression of E- cadherin protein was not related to that of vimentin(r = 0. 108,P 0. 05). Conclusion EMT phenomenon occurs in NSCLC,panticalarly in the poorly differentiated adenocarcinoma." @default.
