Evaluation of the soluble fragments of cytokeratin 19 (CK19) in non-small cell lung cancer (NSCLC)

This study compared the diagnostic efficacy of serum CK19 determination (Cyfra 21-1) with other tumour markers, such as CEA, SCC, NSE, TPA, in patients with resected non-small lung cancer. Tumour marker levels were tested in 90 patients with benign lung disease and at diagnosis in 72 patients with proven NSCLC, 39 squamous cell carcinoma and 33 adenocarcinoma. At presentation baseline levels of all tumor markers were significantly higher (p<0.05) in lung cancer patients than in control subjects, except for NSE. A significant increase (p<0.05) in serum concentrations was observed from stage I to stage IIIb only for Cyfra 21-1 (stage I/II, median=2.7 ng/ml; stage IIIb, median=6.3 ng/ml) and TPA (stage I/II, median=89.8 IU/ml; stage IIIb, median=170.7 IU/ml). Receiver operating characteristic (ROC) analysis was performed to evaluate the best threshold values and the global accuracy of each marker. The highest global sensitivity for NSCLC was reached by TPA (70.8%), whereas that of Cyfra 21-1 was 50%. According to tumour histology, significant difference (p<0.05) in serum levels were found only for CEA (adenocarcinomas, median=5.6 ng/ml; squamous cell carcinoma, median=3.2 ng/ml) and SCC (adenocarcinomas, median=1.0 ng/ml; squamous cell carcinoma, median=1.5 ng/ml). As regards squamous cell carcinoma histotype, the highest sensitivity was obtained by TPA (74.4% at a specificity of 62.2%) and for adenocarcinomas by CEA (78.8% at a specificity of 85.6%). Tumour marker levels were also determined during the follow-up of 10 patients. The best sensitivity in detecting relapses was shown by CEA (90%), followed by TPA (70%), SCC (50%), Cyfra 21-1 (40%) and NSE (10%), even though the CEA test displayed a high percentage of false positive results (98.1%) in patients with no evidence of disease (NED).

Comparison of Cyfra 21-1 and SCC assays in head and neck tumours.

Patients with head and neck tumours (HNT) have a high risk of early locoregional relapse that is difficult to diagnose. This study evaluated the usefulness of the serum Cyfra 21-1 assay compared to squamous cell carcinoma antigen (SCC) assay for monitoring such patients. Three hundred and twelve HNT patients, including 204 newly diagnosed patients, were followed up for a median of 446 days with serial serum assays for SCC and Cyfra 21-1. Untreated patients showed SCC and Cyfra 21-1 serum levels correlated with each other: concentration was correlated to clinical stage, tumour size (as T1 + T2 vs. T3 + T4) and nodal status. Cyfra 21-1, but not SCC, was related to the presence of metastases and the primary tumour site, with a univariate prognostic value for disease-free survival (p = 0.015). Cox's regression analysis showed that only Cyfra 21-1 was associated with a risk of relapse (p = 0.027). The random coefficient growth curve model applied to serial SCC and Cyfra 21-1 measurements of 111 patients showed that only Cyfra 21-1 exhibited a significant difference between patients with and without relapses. We found Cyfra 21-1 to be more closely related to initial clinical data and disease evolution than SCC, and therefore propose the use of Cyfra 21-1 for monitoring head and neck cancers.

目的 探讨晚期非小细胞肺癌（NSCLC） 患者血清癌胚抗原（CEA） 、糖类抗原（CA125）、非小细胞肺癌相关抗原（Cyfra21-1）水平与无疾病进展生存期的相关性。方法 选取2012年6月至2014年5月于宜昌市第二人民医院确诊的非小细胞肺癌患者120例,对其临床资料进行回顾性分析,了解CEA、CA125、Cyfra21-1水平与无疾病进展生存期的相关性。结果 与鳞癌患者相比,血清CEA水平在肺腺癌患者中明显升高（P＜0.05）;血清CA125水平在Ⅳ期肺腺癌患者中明显升高（P＜0.05）;血清Cyfra21-1在患者疾病一般特征中差异未见统计学意义（P＞0.05）。血清CEA、CA125、Cyfra21-1水平升高的患者中位无疾病进展生存期分别为4.2、4.5、4.3月,与正常组相比差异均有统计学意义（P＜0.05）。结论 晚期非小细胞肺癌患者CEA、CA125、Cyfra21-1升高与无疾病进展生存期存在明显的相关性,临床医师可通过检测患者血清CEA、CA125、Cyfra21-1水平判断预后。     

Serum level of cytokeratin 19 fragment (CYFRA 21-1) indicates tumour stage and prognosis of squamous cell carcinoma of the oesophagus

To determine the clinical efficacy of serum concentration of cytokeratin 19 fragment (CYFRA 21-1), sera from 66 patients with oesophageal squamous cell carcinoma were examined, and 54 surgically resected specimens were immunohistochemically stained for cytokeratin 19 (CK-19). The patients with positive CK-19 staining in the tissues of their carcinomas had significantly higher serum CYFRA 21-1 levels compared with those with negative CK-19 staining. When the cut-off value was defined as 2.0 ng/mL, CYFRA 21-1 had a higher positive ratio than that of either squamous cell carcinoma antigen (SCC-Ag) or carcinoembryonic antigen (CEA). Serum CYFRA 21-1 level increased significantly along with the clinical stages. In addition, serum CYFRA 21-1 level served as a prognostic factor for patients with oesophageal carcinoma after surgery, whilst SSC-Ag and CEA is not connected with the outcome. These findings suggest that the serum CYFRA 21-1 probably originated from the tumour tissue is an important marker for determining the stage and outcome of oesophageal carcinoma.     

Cyfra21-1和CEA及CRP联合检测对食管癌诊断价值的探讨

Follow-up with serum Cyfra 21-1 in patients with squamous cell carcinomas of the head and neck

OBJECTIVE: Finding tumor markers for disease progression, and especially development of distant metastases, is desirable for patients with squamous cell carcinoma of the head and neck (SCCHN). Elevated serum levels of Cyfra 21-1 (cytokeratin fraction 21-1) have been frequently associated with disease progression in patients with lung cancer. In SCCHN, Cyfra 21-1 has not been established as a routine tumor marker yet, probably due to difficulties in finding the appropriate cut-off for the serum level. The aim of this study was to investigate whether assessment of changes in serum Cyfra 21-1 over time can predict distant metastases in patients with SCCHN, without attempting to establish an arbitrary cut-off for abnormal levels. METHODS: Cyfra 21-1 serum levels of 25 patients with SCCHN and distant metastases were evaluated by means of an ELISA test kit. RESULTS: There was a wide range of Cyfra 21-1 serum levels at the time of primary diagnosis, without correlation with tumor size, lymph node status, time to recurrence, or presence of distant metastases. All patients had a clear increase of Cyfra 21-1 levels which preceded the appearance of distant metastases clinically. CONCLUSIONS: Due to the wide range of Cyfra 21-1 levels at the time of primary tumor diagnosis, Cyfra-21-1 is neither a suitable screening marker for SCCHN, nor for diagnosis of distant metastases at the time of initial diagnosis of the tumor, but is of evident prognostic value for follow-up, especially for early detection of distant metastases.     

五项血清肿瘤标志物联合检测在肺癌诊断中的应用

目的：探讨癌胚抗原（CEA）、神经元特异性烯醇化酶（NSE）、鳞状上皮抗原（SCC）、细胞角蛋白19片段抗原（Cyfra21—1）和糖链抗原125（CA125）5项肿瘤标志物联合检测在肺癌诊断中的价值。方法：采用电化学发光法及酶化学发光法测定81例肺癌、32例良性肺病患者和30例健康人的血清CEA、NSE、SCC、cyfra21—1和CA125水平。结果：肺癌组血清CEA、NSE、SCC、Cyfra21—1和CA125的阳性检出率（分别为49．38％、55．56％、23．46％、62．96％、39．51％）明显高于良性肺病组和健康对照组。肺癌组5项肿瘤标志物阳性率随肿瘤临床分期而升高。其中CEA在肺腺癌中明显升高（P〈0．05），NSE以小细胞癌升高明显（P〈0．05），SCC在肺鳞癌中明显升高（P〈0．01），Cyfra21—1以非小细胞肺癌升高明显（P〈0．01）。5项肿瘤标志物联合检测比单项检测的阳性率和准确性更高。结论：外周血CEA、NSE、SCC、Cyfra21—1和CA125联合检测可提高肺癌的阳性检出率，CEA、NSE、SCC和Cyfra21—1对肺癌病理分型有重要的临床参考价值。     

血清CYFRA21-1、SCC-Ag、LDH联合检测对肺鳞癌与肺部感染鉴别诊断的价值初探

目的:探讨血清SCC-Ag、CYFRA21-1、LDH联合检测对肺鳞癌与肺部感染鉴别诊断的价值。方法:回顾性分析2017年1月至2018年3月北京市和平里医院消化科及呼吸科住院或门诊就诊的110例患者,其中肺鳞癌患者55例,肺部感染患者55例,使用化学发光法和速率法分别检测血清CYFRA21-1、SCC-Ag、LDH表达水平,以及肺鳞癌患者Ⅰ-Ⅳ期CYFRA21-1、SCC-Ag表达水平,经统计学处理后对比分析。结果:肺鳞癌组患者血清CYFRA21-1高于肺部感染组患者,差异有统计学意义(P<0.05);同时肺部感染组患者血清SCC-Ag表达高于肺鳞癌组,有统计学差异(P<0.05);Ⅰ期、Ⅱ期肺鳞癌组患者血清CYFRA21-1较Ⅳ期患者相比差异显著,随着肿瘤的进展,血清CYFRA21-1、SCC-Ag均有上升的趋势;肺鳞癌组患者血清LDH表达水平显著高于肺部感染组患者(P<0.01)。结论:独立的每个肿瘤标志物因其自身的特异性和敏感性,可能导致诊断的局限性,血清CYFRA21-1、SCC-Ag、LDH联合检测对肺鳞癌与肺部感染辅助鉴别诊断可能具有一定临床价值。     

Evaluation of a new tumour marker in patients with non-small-cell lung cancer: Cyfra 21.1.

The Cyfra 21.1 assay is a newly developed test which measures in serum a fragment of cytokeratin 19. We evaluated this marker in 212 patients with non-small-cell lung cancer (NSCLC), predominantly stage 3a-b and 4, and compared it with three other markers: carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC) and tissue polypeptide antigen (TPA). Sensitivities for Cyfra 21.1, TPA, CEA and SCC (using cut-off levels corresponding to a 95% specificity for benign lung diseases) were 40%, 40%, 42% and 19% respectively. The sensitivity of CEA was significantly higher in patients with adenocarcinomas compared with the other three markers, while the sensitivity of Cyfra 21.1 and TPA was significantly higher in patients with squamous cell carcinomas. The value of Cyfra 21.1 for monitoring disease during chemotherapy could be evaluated in 23 patients with squamous cell carcinomas. When the cases of lead time were included a concordance between clinical evaluations according to WHO response criteria and evaluations according to changes in the marker levels of 74% was found. The criteria defined for marker response were a 65% decrease in the marker level for a partial response and a 40% increase for progressive disease. In particular, increasing levels of this marker indicated usually disease progression. In conclusion, Cyfra 21.1 is a useful serum marker for patients with NSCLC, especially for disease monitoring of patients with squamous cell carcinoma during and after chemotherapy.

Clinical significance of osteopontin in esophageal squamous cell carcinoma: comparison with common tumor markers

OBJECTIVE: Osteopontin (OPN) is a secreted integrin-binding glycophosphoprotein that may have a role in head and neck squamous cell carcinoma (SCC). To evaluate the clinical significance of OPN in esophageal squamous cell carcinoma (ESCC), we compared plasma OPN levels with those of common tumor markers. METHODS: Preoperative plasma OPN levels were measured by enzyme immunoassay in 103 ESCC patients. Serum SCC antigen, Cyfra 21-1, and carcinoembryonic antigen (CEA) levels were also measured routinely at admission by radioimmunoassay. RESULTS: Plasma OPN levels ranged from 82.8 to 1,980 ng/ml. High OPN level was associated with lymph node metastasis (p = 0.05), but not with tumor histology or depth of invasion. The overall survival of the patients with high OPN levels was worse than that of those with low OPN levels (p = 0.02). SCC antigen and Cyfra 21-1 levels were associated with the depth of tumor invasion, the tumor diameter, lymph node metastasis, and the overall survival, but CEA was not associated with these clinicopathological factors. Combined evaluation of OPN plus Cyfra 21-1 or OPN plus SCC antigen was useful as an independent prognostic indicator. CONCLUSION: Measurement of the plasma OPN level, as well as serum SCC antigen and Cyfra 21-1, may help to predict the progression of ESCC.

目的目前食管鳞状细胞癌(esophageal squamous cell carcinoma,ESCC)尚缺乏灵敏度高的诊断标志物,大多数患者确诊时已到中晚期且预后不良。本研究探讨热休克蛋白90α(heat shock protein 90α,HSP90α)、细胞角蛋白片段19抗原21-1(cytokeratin fragment 19antigen 21-1,Cyfra21-1)和癌胚抗原(carcinoembryonic antigen,CEA)联合检测对ESCC患者的诊断价值及其临床意义。方法选取2016-01-06-2018-12-10山东省肿瘤医院血液采集时未接受放化疗及手术治疗的118例ESCC患者为研究对象并采集血样,同期收集33名健康体检者血液标本。采用酶联免疫吸附测定法检测血浆HSP90α表达水平,采用电化学发光法检测血清Cyfra21-1和CEA表达水平。ROC曲线评估3个指标单独或联合检测对ESCC的诊断效能,各指标表达与食管癌患者临床病理因素的关联分析采用χ^2检验。结果 ESCC患者中HSP90α、Cyfra21-1和CEA中位数(四分位间距)分别为62.535(45.190~107.708)、3.365(2.038~4.633)和3.545(2.190~5.000)ng/mL,均高于对照组的48.882(36.190~64.033)、1.970(1.590~2.380)和1.990(1.990~2.635)ng/mL,差异有统计学意义,Z值分别为-3.566、-4.131和-4.829,均P=0。ESCC患者中HSP90α、Cyfra21-1和CEA阳性表达与患者的肿瘤大小、远端转移及TNM分期,差异均有统计学意义,P<0.05。ESCCⅣ期患者HSP90α、Cyfra21-1及CEA表达水平高于Ⅲ期患者,差异有统计学意义,P<0.05。ESCC患者中HSP90α与Cyfra21-1、CEA联合检测双阳性率分别为31.36%和34.75%,表达呈正相关(r=0.23,P=0.012;r=0.397,P=0)。HSP90α与Cyfra21-1、CEA联合检测对ESCC患者的诊断灵敏度为78.0%,特异性为72.8%,曲线下面积为0.862。结论肿瘤标志物HSP90α和Cyfra21-1、CEA在ESCC患者中呈现高表达状况,联合检测能够提高ESCC患者的诊断灵敏性和特异性,3种肿瘤标志物联合检测对于ESCC早期诊断与评估分期有一定价值。     

Prognostic value of pretreatment CEA, SCC-Ag and CA 19-9 levels in sera of patients with non-small cell lung cancer.

The levels of carcinoembryonic antigen (CEA), squamous cell associated antigen (SCC-Ag) and carbohydrate antigenic determinant 19-9 (CA 19-9) were assessed in 70 patients with non-small cell lung cancer (NSCLC) and in 20 patients with non-malignant lung diseases. Increased levels of CEA and CA 19-9 were observed in 55.7 and 44.2%, respectively, mostly in patients with adenocarcinoma (adeno C; 69.5 and 56.5%). Increased levels of SCC-Ag were observed in 45.7%, first in patients with squamous cell carcinoma (68.6%). Serum CEA, CA 19-9 and SCC-Ag levels were correlated with the postoperative, pathological stage of disease. Positive CEA levels in patients with adeno C were present in 50% of stage 1, 66.6% of stage 2 and 88.8% of stage 3; positive CA 19-9 levels in patients with adeno C were present in 30% of stage 1, 66.6% of stage 2 and 80% of stage 3; positive SCC-Ag levels were present in patients with squamous LC in 50% of stage 1, 83.3% of stage 2 and 73.7% of stage 3. The study proved that preoperative CEA, SCC-Ag and CA 19-9 determination have been shown to be of prognostic value in patients with NSCLC. A high preoperative antigen value suggests a worse prognosis than a lower value.
