脂肪酸合成酶在非小细胞肺癌中的表达及临床意义 总被引:1,自引:0,他引:1
目的:研究脂肪酸合成酶(fattyacidsynthase,FAS)在非小细胞肺癌中的表达及其临床意义。方法:对107名随访5年的非小细胞肺癌手术患者的石蜡标本进行FAS的免疫组织化学染色和半定量分析,并与肺良性病变,肺正常组织进行对照。结果:与肺部良性病变,肺正常组织相比,FAS在肺癌组织中高表达,阳性表达率40.2%(43/107),有显著性的差异(P<0.01)。FAS的表达与患者性别,年龄,肿瘤部位,淋巴结转移,病理类型,分化无关;与pTNM分期,原发肿瘤T分期有关(P<0.05)。FAS阳性表达患者的5年生存率远低于阴性患者(16%vs43%,P<0.01)。结论:FAS在非小细胞肺癌组织中表达增高,酶活性增强;FAS在肺癌组织中表达增高有提示不良预后的作用。 相似文献

Background:
Early-stage non-small cell lung cancer (NSCLC) patients have a high risk of disease relapse despite curatively intended surgical resection, and the detection of tumour cells in the bone marrow could be one method of determining the presence of the disseminated disease in its early stages.Methods:
Bone marrow aspirates were collected from 296 patients at the time of surgery, and the presence of disseminated tumour cells was determined with the help of immunomagnetic selection (IMS) using the MOC31-antibody recognising EpCAM and with the help of standard immunocytochemistry (ICC) using the anti-cytokeratin (CK) antibodies AE1/AE3.Results:
Disseminated tumour cells were found in 152 of 252 (59%) bone marrow samples using IMS and in 25 of 234 (11%) samples using ICC. No association between the two detection methods was observed. The presence of EpCAM+ cells was not associated with any clinicopathological parameters, whereas a higher frequency of CK+ cells was found in patients with an advanced pT status. Disseminated tumour cells, as detected using IMS, had no prognostic impact. Patients with CK+ cells in the bone marrow had a reduced relapse-free survival, but the difference was not statistically significant.Conclusion:
Our findings do not support the further development of DTC detection for clinical use in early-stage NSCLC. Future studies should include the molecular characterisation of DTCs, along with an attempt to identify subpopulations of cells with biological and clinical significance. 相似文献8.
Raf-1 kinase inhibitor protein (RKIP) expression was associated with the onset, development, invasion, and metastasis of numerous tumor types including prostate cancer, melanoma, colorectal cancer, liver cancer, and breast cancer. However, RKIP mRNA expression and the clinical significance in non-small cell lung cancers (NSCLC) remain unresolved. Real-time PCR was performed to detect the expression of RKIP mRNA in 126 pairs of lung tumor tissues (TT) and surrounding normal tissues (sNT). Correlations between RKIP mRNA expression and clinicopathological features were evaluated by statistical analysis. In the 126 patients examined, RKIP mRNA expression was significantly lower in lung TT than the sNT (p?<?0.05). Our results indicated that downregulation of RKIP mRNA expression was associated with a poorer N-stage (p?=?0.019) and poorer pathological TNM stage (p?=?0.015). However, no significant association was observed between the expression status of RKIP mRNA and clinicopathologic factors, such as gender, age, histological type, and the size of the tumor (p?>?0.05). The level of RKIP mRNA expression was found to be significantly downregulated in NSCLC, and the lower mRNA levels correlated with poorer differentiation, advanced pathologic TNM stage in patients with NSCLC. 相似文献

目的:评估非小细胞肺癌(NSCLC)细胞中胰岛素样生长因子-1受体(IGF-1R)表达水平,并探讨其与临床特征和生存率的关系。方法:78例NSCLC患者均接受肺癌完全性切除术,NSCLC患者的病理标本采用免疫组织化学法染色检测IGF-1R在NSCLC组织中的表达,并进行染色细胞的百分比评分及染色强度评分。将评分相加,大于3分样本被分类为高表达,反之为低表达。结果:IGF-1R高表达与淋巴结转移和复发相关(P=0.034,P=0.006)。IGF-1R高表达较IGF-1R 低表达与显著降低总体生存率相关(P=0.011)。经多因素分析,IGF-1R表达与NSCLC患者预后独立相关。结论:IGF-1R的过表达可能是NSCLC患者淋巴结转移、复发和术后预后的一个有效的预测因子。 相似文献

Clinical significance of heparanase activity in primary resected non-small cell lung cancer 总被引:4,自引:0,他引:4
Takahashi H Ebihara S Okazaki T Suzuki S Asada M Kubo H Sasaki H 《Lung cancer (Amsterdam, Netherlands)》2004,45(2):207-214
Clinicopathological significances of heparanase activity in non-small cell lung cancer (NSCLC) were investigated by analyzing 76 resected specimens of NSCLC. Heparanase activities in NSCLC were significantly higher than non-cancerous lung tissues (P < 0.0001). The heparanase activities of NSCLC were significantly higher in larger diameter tumors (P = 0.0141) or with metastasis to ipsilateral mediastinal lymph nodes (P = 0.0004). The activities of heparanase in primary tumors were increased significantly according to the pathological stage of the progression of the disease (P =0.0009). Among the clinicopathological parameters, histological cell type and evidence of ipsilateral lymph node metastasis showed a significant association with elevated heparanase activities, whereas age, degree of differentiation and tumor diameter did not. Kaplan-Meier curves for overall and disease-free survival demonstrated a significant difference between patients with elevated and non-elevated heparanase activity by log-rank test (P = 0.0145 and 0.0002, respectively). Multivariate analysis showed heparanase activity was an independent factor to influence disease-free survival in our study. These results suggest that heparanase activity could be used as a prognostic indicator for postoperative patients with NSCLC and heparanase might be a promising molecular target for treatment of NSCLC. 相似文献

目的:分析非小细胞肺癌(NSCLC)组织中N-myc下游调节基因1(NDRG1)的表达及临床意义.方法:免疫组织化学SP和反转录-聚合酶链式反应(RT-PCR)方法分别检测NDRG1在NSCLC组织中的蛋白和mRNA表达.结果:NDRG1的表达定位于细胞质(46/85,54.1%)、细胞核(18/85,21.2%)和细胞膜(9/85,10.6%),总阳性率为61.2% (52/85).NDRG1在癌旁正常肺组织中的表达(22/85,25.9%)低于肺癌组织,P=0.000.NDRG1在淋巴结转移癌组织中的表达(17/40,42.5%)低于原发灶癌(P=0.003),但高于正常肺组织,P=0.002.NDRG1蛋白表达与肿瘤大小呈正相关,肿瘤≥3 cm组的NDRG1蛋白表达(45/59,76.3%)高于肿瘤<3 cm组(7/26,26.9%),P=0.000.NSCLC组织中NDRG1 mRNA水平高于癌旁正常肺组织,P=0.000.NSCLC组织中NDRG1 mRNA表达水平与蛋白表达水平呈正相关,P=0.025.另外,NDRG1阳性组患者的平均生存时间为(35.84±15.07)个月,明显低于NDRG1阴性组患者(63.69±12.16)个月,P=0.002.结论:NSCLC组织中NDRG1的表达相对于癌旁正常肺组织升高,并随肿瘤体积增大而上调,其过表达可能具有提示患者预后不良的意义. 相似文献

目的:研究PFTAIRE蛋白激酶1(PFTK1)在人类非小细胞肺癌(NSCLC)组织中的表达及其与NSCLC临床病理特征之间的关系,揭示PFTK1的表达在NSCLC中的临床意义。方法:采用免疫组织化学方法检测119例NSCLC组织中PFTK1的表达情况,并用χ2检验比较样本率,Kaplan-Meier法计算生存率,Log-Rank检验进行生存率的比较。结果:PFTK1在NSCLC组织中呈胞核和胞浆阳性。与癌旁组织比较,在119例NSCLC组织中,有76例肺癌组织PFTK1表达水平升高,占63.9%(76/119)。PFTK1的表达在NSCLC不同T分期间以及是否存在淋巴结转移组间的差异均具有统计学意义(P均<0.05),与年龄、性别、临床分期、病理分级、病理类型、肿瘤大小以及区域淋巴结N分期无明显相关性(P>0.05)。在肺鳞癌患者中控制分层因素N分期后进行生存分析显示PFTK1的表达水平越高,患者生存时间越短(P<0.05)。结论:PFTK1在人NSCLC中表达水平升高,并且PFTK1的表达与NSCLC的T分期及淋巴结转移具有相关性,影响NSCLC患者预后。PFTK1有望成为NSCLC潜在的生物学标志。 相似文献

非小细胞肺癌新亚型分类的临床意义 总被引:3,自引:0,他引:3
目的:明确非小细胞肺癌(non-small cell lung cancer,NSCLC)中细支气管肺泡细胞癌(bronchioloalveolar carcinoma,BAC)成分与临床治疗和预后的相关性。方法:收集上海市胸科医院随访资料完整的386例NSCLC病例(pTNMⅠ~Ⅲ期),其中男性275例,女性111例。按WHO2004年版肺癌病理学分类标准重新核对组织病理学亚型,分组:鳞癌、腺癌、腺癌+BAC、腺鳞癌、腺鳞癌+BAC、其他(大细胞癌、肉瘤样癌)。结果:NSCLC伴有BAC成分占NSCLC总数的21.8%;鳞癌占31.6%,腺癌占36.8%(其中1/2伴BAC成分),腺鳞癌占16.6%(其中1/5伴BAC成分),其他亚型占15.0%。统计学分析表明NSCLC分为这6个新亚型与pTNM分期有相关性(P〈0.05),在Ⅰ期NSCLC中以鳞癌和含有BAC成分的腺癌较多见。通过Kaplan-Meier生存曲线的进一步分析,发现含有BAC成分的复合型NSCLC的预后要优于其单纯型,生存期有显著的统计学差异(P〈0.05);本组病例预后最好的是腺癌伴BAC成分,其余依次为鳞癌、腺鳞癌伴BAC成分、腺癌、其他亚型和腺鳞癌。结论:首次明确了腺鳞癌伴BAC成分的临床意义,提示NSCLC伴有BAC成分预后较好,NSCLC亚型的新分类具有独立的预后意义,可为探讨NSCLC治疗的新方案提供思路。 相似文献
