小细胞肺癌与非小细胞肺癌中神经元烯醇化酶检测的临床意义 总被引:2,自引:0,他引:2
目的:探讨检测小细胞肺癌(small cell lung cancer,SCLC)与非小细胞肺癌(non-small cell lung cancer,NSCLC)患者血清神经元烯醇化酶(neuron specific enolase,NSE)对诊断、治疗及预后的临床意义。方法:放射免疫法检测NSCLC182例、SCLC33例(动态观察其中70例治疗有效的肺癌患者治疗后血清NSE的变化)、肺良性病变161例和正常对照组158例的血清NSE。结果:健康人NSE水平为(9.5±3.4)μg/L,异常率为10.1%(16/158);肺良性病变的NSE水平为(10.0±5.4)μg/L,异常率为16.8%(27/161);肺癌患者NSE水平为(20.7±22.5)μg/L,异常率为40.0%(86/215)。肺癌患者NSE水平和异常率均明显高于正常对照组,P=0.004。肺良性病变NSE水平亦有所升高,但与对照组相比差异无统计学意义,P=0.095。NSE水平随分期升高而增加,晚期肺癌患者NSE水平显著高于早期肺癌患者,P=0.004。有效治疗后NSE水平明显下降,P=0.003。NSE水平低的患者较NSE水平高的患者相对预后好。结论:NSE不仅可作为SCLC的标志,对NSCLC的诊断、治疗及预后评价也有一定的临床价值。 相似文献

目的:探讨血清NSE对小细胞肺癌的诊断,分期及预后的临床价值,以及同时探讨标本溶血程度对NSE浓度的影响。方法:采用ELISA法,检测83例SCLC患者,63例肺良性疾病,62例正常对照及35例溶血标本的NSE水平。结果:SCLC组血清NSE水平(37.64±36.95)μg/L显著高于肺良性疾病组(11.94±4.19)μg/L和正常对照组(8.92±3.95)μg/L(P〈0.01);SCLCⅢ,Ⅳ期患者血清NSE水平(53.58±40.87)明显高于Ⅰ,Ⅱ期(14.66±6.48)(P〈0.01)。SCLC治疗前NSE水平显著高于治疗后(P〈0.05)。以NSE水平为指标诊断SCLC的敏感性、特异性、准确性,分别为67.3%、83.1%和85.4%。标本溶血对NSE测定影响很大,并且随着溶血程度的增加NSE结果显著升高。结论:NSE可作为较好的小细胞肺癌肿瘤标志物,对SCLC诊断,尤其对临床分期及预后有重要参考价值。血清NSE值随溶血程度呈递增趋势,因此,应严格避免溶血,以减少假阳性的发生。 相似文献

An analysis of prognostic factors in small cell lung cancer has been made using presentation data from 86 of 101 consecutive patients referred to The Finsen Institute for chemotherapy. Prognosis was in univariate analysis significantly correlated with performance status (PS), disease extent, serum lactate dehydrogenase (LDH), neuron specific enolase (NSE), alpha-1-acid glycoprotein and plasma sodium. Multivariate analysis, taking stage of disease into account, resulted in selection of PS and NSE as the most influential of the investigated variables. LDH was excluded as an independent prognosticator, but there was a strong correlation between the influence of LDH and NSE (coefficient: -0.38) as well as between their serum concentrations (coefficient: 0.72). LDH and NSE apparently have similar prognostic influence, and NSE seems superior to LDH. A firm conclusion should, however, await our investigation of a large series of patients. 相似文献

Cyfra 21-1, neuron specific enolase and prognosis of non-small cell lung cancer: prospective study in 621 patients 总被引:11,自引:0,他引:11
BACKGROUND: CYFRA 21-1, a serum cytokeratin 19 fragment, and neuron specific enolase (NSE), the gamma-subunit of enolase, are putative markers of lung cancer. Their clinical applicability as prognostic factors in non-small cell lung cancer (NSCLC) would need an appraisal by simultaneous evaluation of other known survival determinants in a large population followed over a long period. AIM: To determine the prognostic value of different clinical and routine biological variables at presentation with particular attention paid to the above-mentioned markers. METHODS: 621 histologically proven and previously untreated NSCLC patients have been prospectively studied (seven were lost to follow-up). Median follow-up was 4 years and 2 months. At presentation, 16 clinical and biological variables were recorded. Serum NSE and CYFRA 21-1 were assayed blind without any clinical information given. RESULTS: The serum CYFRA 21-1 distribution differed significantly according to histology, disease stage and performance status, with the highest levels observed in squamous cell carcinomas, metastatic stage, positive mediastinal nodal status and poor performance status. However, the respective "receiver operating characteristic" curves showed that the CYFRA 21-1 serum level did not accurately predict tumour stage. Serum NSE distribution correlated neither with tumour stage nor with performance index and its sensitivity in the whole NSCLC was low. In the Cox proportional hazard model, the following variables were independent determinants of a poor outcome: performance status 2 or 3, hazard ratio (HR): 2.25; Nodal status N(2-3), HR: 1.84; Metastatic disease, HR: 1.73; NSE>12.5 ng/ml, HR: 1.52; CYFRA 21-1>3.6 ng/ml, HR: 1.41 and Tumour status T(3-4), HR: 1.31. When the survival analysis was restricted to the 274 patients affected by a metastatic stage, we observed that performance status, nodal status, NSE and CYFRA 21-1 remained prognostic determinants with similar hazard ratios. CONCLUSION: The prognostic information given by a high serum CYFRA 21-1 level is independent from other well-known variables such as performance status and disease stage and is perennial throughout extended follow-up period. A high NSE level also prognosticates a poor outcome probably by reflecting tumour heterogeneity and underestimated neuroendocrine differentiation. 相似文献

An analysis has been made of the relationship between neuron specific enolase (NSE) in serum and immunohistochemically identified occurrence of NSE in the primary tumour in 56 patients with small cell lung cancer (SCLC). Patients were referred to the Finsen Institute for treatment during a period of 18 months. Forty-six tumours (82%) were NSE positive. To compare this staining with the occurrence of NSE in serum, a histological staining index (HSI) was established by semiquantitative gradation of the staining. No significant differences were found between distribution of serum NSE values in different HSI categories, and a high ranking in HSI was not associated with a high level of serum NSE. Both univariate and multivariate analysis selected serum NSE and not HSI as the most influential prognostic factor in SCLC. 相似文献

In a group of seventy patients with small cell lung cancer the prognostic value of serum tumour markers was determined. Thymidine kinase (TK), tissue polypeptide antigen (TPA) and lactate dehydrogenase (LDH) but not neuron specific enolase (NSE) correlated significantly with survival. Since all markers were strongly interrelated with each other and with the extent of disease, the combined determination of TK, TPA and LDH or the combination of disease extent and a marker yielded no more prognostic information than a single measurement of one of these variables. 相似文献

Evaluation of a radioimmunoassay for neuron specific enolase in small cell lung cancer 总被引:1,自引:0,他引:1

A radioimmunoassay for neuron specific enolase (NSE), a marker of neuroendocrine differentiation, has been evaluated in small cell lung cancer (SCLC). In untreated patients 25/38 (68%) with localized SCLC had raised blood levels of NSE (greater than 13 ng ml-1), in extensive disease 34/39 (87%) patients had raised NSE levels. In patients with non-small cell lung cancer (NSCLC) the serum levels were raised in 16/94 (17%). In extensive tumours of non-pulmonary origin NSE levels were increased in 24/116 (20%) patients. Longitudinal studies indicated a good correlation between the response to chemotherapy and fall of NSE levels. Tumour progression was accompanied by a rising NSE in 25/29 patients, with doubling times of 7-90 days. In patients with progression with a normal NSE the recurrence was a NSCLC. Cerebral metastases occurring as the only recurrence during clinical complete remission were not accompanied by a rise of NSE. Serum NSE levels provides a valuable monitor for SCLC during and after chemotherapy. 相似文献

Prognostic factors in non-small cell lung cancer surgery. 总被引:4,自引:0,他引:4

AIMS: Complete surgical resection of primary tumours remains the treatment with the greatest likelihood for survival in early-stage non-small cell lung cancer (NSCLC). Although TNM stage is the most important prognostic parameter in NSCLC, additional parameters are required to explain the large variability in postoperative outcome. The present review aims at providing an overview of the currently known prognostic markers for postoperative outcome. METHODS: We performed an electronic literature search on the MEDLINE database to identify relevant studies describing the risk factors in NSCLC surgery. The references reported in all the identified studies were used for completion of the literature search. RESULTS: Poor pulmonary function, cardiovascular disease, male gender, advanced age, TNM stage, non-squamous cell histology, pneumonectomy, low hospital volume and little experience of the surgeon were identified as risk factors for postoperative outcome. However, with the exception of TNM stage and extent of resection, the literature demonstrates conflicting results on the prognostic power of most factors. The role of molecular biological factors, neoadjuvant treatment and adjuvant treatment is not well investigated yet. CONCLUSIONS: The advantage of knowing about the existence of comorbidity and prognostic risk factors may provide the clinician with the ability to identify poor prognostic patients and establish the most appropriate treatment strategy. The assessment of prognostic factors remains an area of active investigation and a promising field of research in optimising therapy of NSCLC patients. 相似文献

Purpose
There is a need for biomarkers that may help in selecting the most effective anticancer treatments for each patient. We have investigated the prognostic value of a set of angiogenesis, inflammation and coagulation markers in patients treated for advanced non-small cell lung cancer.Patients and methods
Peripheral blood samples were obtained from 60 patients before first line platinum-based chemotherapy ± bevacizumab, and after the third cycle of treatment. Blood samples from 60 healthy volunteers were also obtained as controls. Angiogenesis, inflammation and coagulation markers vascular endothelial growth factor (VEGF), their soluble receptors 1 (VEGFR1) and 2 (VEGFR2), thrombospondin-1 (TSP-1), interleukin-6 (IL6), sialic acid (SA) and tissue factor (TF) were quantified by ELISA.Results
Except for TSP-1, pre- and post-treatment levels of all markers were higher in patients than in controls (p < 0.05). There was a positive and significant correlation between VEGF and VEGFR2 before treatment. VEGF also correlated with inflammatory markers IL-6 and SA. Moreover, there was a positive and significant correlation between levels of VEGFR1 and TF. Decreased levels of TSP-1 and increased levels of VEGF were associated with shorter survival. Bevacizumab significantly modified angiogenesis parameters and caused a decrease of VEGF and an increase of TSP-1.Conclusion
Angiogenesis, inflammation and coagulation markers were increased in NSCLC patients. Increased levels of VEGF and low levels of TSP-1 correlated with a poor prognosis. 相似文献19.
