Evaluation of pleural CYFRA 21-1 and carcinoembryonic antigen in the diagnosis of malignant pleural effusions.

CYFRA 21-1 assay, measuring cytokeratin 19 fragments, was compared with carcinoembryonic antigen (CEA) assay, as an addition to cytological analysis for the diagnosis of malignant effusions. Both markers were determined with commercial enzyme immunoassays in pleural fluid from 196 patients. Cytological analysis and/or pleural biopsy confirmed the malignant origin of the effusion in 99 patients (76 carcinomas, nine pleural mesotheliomas and 14 non-epithelial malignancies). Effusions were confirmed as benign in 97 patients (33 cardiac failures, 39 infectious diseases--including 12 tuberculosis-- and 25 miscellaneous effusions). Both markers were significantly higher in malignant than in benign effusions. All the patients with non-epithelial malignancies presented CYFRA and CEA values lower than the 95% diagnostic specificity thresholds (100 and 6 ng ml(-1) respectively). The diagnostic sensitivity in the group of carcinomas and mesotheliomas was similar for CYFRA (58.8%) and CEA (64.7%). However, CEA had a significantly higher sensitivity in carcinomas (72.4% vs 55.3%), while CYFRA had a clearly higher sensitivity in mesotheliomas (89.9% vs 0%). Interestingly, 12 out of the 16 malignant effusions with a negative cytology were CEA and/or CYFRA positive. Regarding their high diagnostic sensitivity and their complementarity, CEA and CYFRA appear to be very useful for the diagnosis of malignant pleural effusions when cytology is negative.     

肺鳞癌CEA及CYFRA 21—1和NSE检测的临床意义

目的 研究癌胚抗原(CEA)、细胞角质蛋白(CYFRA21-1)和神经元特异性烯醇化酶(NSE)在肺鳞状细胞癌(SQC)患者血清中的水平与患者TNM分期、可否行手术治疗及预后之间的关系.方法 检测210例SQC患者的血清标本(Ⅰ期20例、Ⅱ期27例、ⅢA期55例、ⅢB期80例、Ⅳ期28例)CEA、CYFRA 21-1和NSE的血清水平.NSE和CYFRA21-1采用放免测定,CEA采用化学发光法测定.结果 CYFRA 21-1升高最为常见.CEA和CYFRA 21-1与TNM分期相关,而NSE与TNM分期无关.CEA和CYFRA 21-1血清水平均值与可手术(1、Ⅱ、ⅢA)和不可手术(ⅢB、Ⅳ期)有相关性(P<0.001).NSE血清水平均值与可否手术差异无显著性.结论 治疗前CYFRA 21-1和NSE的血清浓度与预后有关,可作为SQC患者可否手术的参考指标,并可为SQC预后判断提供重要信息.     

Diagnostic value of CEA, CA 15-3, CA 19-9, CYFRA 21-1, NSE and TSA assay in pleural effusions

The aim of this study was to evaluate the individual and combined diagnostic utility of six tumor markers in patients with pleural effusion. Pleural and serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), cytokeratin fragment 19 (CYFRA 21-1), neuron-specific enolase (NSE) and total sialic acid (TSA) were assayed in 74 patients with pleural effusions (44 malignant and 30 benign). All tumor markers except TSA and NSE were increased in both serum and pleural fluid of patients with malignant diseases. Using the cut-off values 3 ng/ml, 14 U/ml, 5 U/ml, 8 ng/ml and 70 mg/dl for pleural fluid CEA, CA 15-3, CA 19-9, CYFRA 21-1 and TSA, respectively, the sensitivity (%) and specificity (%) of these tumor markers were as follows: CEA; 52/77, CA 15-3; 80/93, CA 19-9; 36/83, CYFRA 21-1; 91/90, TSA; 80/67, for differentiating malignant effusions from benign. When CA 15-3 and CYFRA 21-1 combined, the sensitivity and specificity were increased (100 and 83%, respectively). Classifying the malignant effusions as bronchial carcinoma and malignant pleural mesothelioma, CEA was shown to have the highest sensitivity and specificity (88 and 90%, respectively) while the combination of CEA with other tumor markers increased sensitivity but decreased specificity. According to our results, tumor markers are not suitable for the differential diagnosis of malignancy.

Diagnostic value of CYFRA 21-1, CEA, CA 19-9, CA 15-3, and CA 125 assays in pleural effusions: analysis of 116 cases and review of the literature

Levels of tumor markers in pleural effusions may help to establish the diagnosis of pleural malignancy, but the precise diagnostic value of each marker remains unclear. The aim of this study was to assess the diagnostic value of five common pleural fluid tumor markers, carcinoembryonic antigen (CEA), cytokeratin fragment (CYFRA) 21-1, cancer antigen (CA) 15-3, CA 19-9, and CA 125, and to review the literature from the past 15 years. Pleural fluid samples were collected prospectively from 116 patients and assayed for CEA, CYFRA 21-1, CA 15-3, CA 19-9, and CA 125 levels. A MEDLINE search of the English-language literature from the past 15 years was also done. Effusions were classified as benign or malignant on the basis of their definitive pathologic or cytologic diagnoses. The levels of all pleural tumor markers were statistically significantly higher in the malignant group than in the benign group. The marker with the highest accuracy was CEA (85.3%); CA 15-3, CYFRA 21-1, and CA 19-9 had similar accuracies (75.2%, 72.4%, and 71.5%, respectively), and CA 125 had the lowest accuracy (40.5%). On univariate analysis, tumor-marker combinations did not result in a greater accuracy than that of CEA alone. On multivariate logistic regression, CA 15-3 and CYFRA 21-1 were significant predictors of malignancy. Among the nine reports in the literature comparing 11 different tumor markers, CEA, CA 15-3, and CYFRA 21-1 yielded the best results. We conclude that pleural fluid analysis should include CEA for the diagnosis of malignancy. CA 15-3 and CYFRA 21-1 may serve as alternative options.

Serum squamous cell carcinoma antigen and CYFRA 21-1 in cervical cancer treatment.

PURPOSE: To analyze whether serum squamous cell carcinoma (SCC) antigen and cytokeratin-19 fragments (CYFRA) levels can assist in selecting patients with locally advanced cervical cancer who will benefit from combined treatment or additive surgery. METHODS AND MATERIALS: Of 114 patients with cervical cancer Stage IB-IV, the first 39 patients received radiotherapy, the following 75 patients received identical radiotherapy plus concomitant chemotherapy (3 cycles of carboplatin and 5-fluorouracil). SCC antigen and CYFRA 21-1 serum levels were measured before treatment, after therapy, and during follow-up. Baseline tumor markers were related to tumor stage and size and clinical outcome. RESULTS: Before treatment, SCC antigen was elevated (>1.9 microg/L) in 60% and CYFRA 21-1 (>2.2 microg/L) in 46% of patients. For all patients, disease-free survival (DFS) was better after combined treatment (67% vs. 43%, p < 0.0005). For patients with elevated baseline SCC antigen, DFS was better after combination therapy (67% vs. 27%, p = 0.001) which resulted more frequently in a normal SCC antigen (93% vs. 65%, p = 0.004). In contrast, in those with a normal baseline CYFRA 21-1, combined therapy resulted in a better DFS (p = 0.04). Patients who achieved a normal SCC antigen or CYFRA 21-1 after treatment had a better DFS (respectively 63 vs. 17% and 64 vs. 30%). Elevated SCC antigen posttreatment indicated residual tumor in 11/12 patients (92%), elevated CYFRA 21-1 in 7/10 patients (70%). Forty-seven patients had a tumor recurrence. At recurrence, SCC antigen was raised in 70% and CYFRA 21-1 in 69%. CONCLUSIONS: In patients with an elevated pretreatment SCC antigen, SCC antigen normalized more frequently with combined treatment and those patients had a better DFS. Elevated SCC antigen or CYFRA 21-1 levels after treatment completion indicated residual tumor in respectively 92% and 70%. The presence of elevated posttreatment levels of SCC antigen or CYFRA 21-1 indicates the need for additional salvage surgery. SCC antigen proved to be superior to CYFRA 21-1 in predicting DFS and disease recurrence.     

Diagnostic value of pleural interleukin 17 and carcinoembryonic antigen in lung cancer patients with malignant pleural effusions

Interleukin 17 (IL-17) has been found to be increased in some human cancers; however, the possible implication of IL-17 in regulating antitumor responses in lung cancer patients with malignant pleural effusions (MPE) remains to be elucidated. This study aimed to investigate the diagnostic value of pleural IL-17 and carcinoembryonic antigen (CEA) in MPE and benign pleural effusions (BPE). Pleural effusion samples from 108 patients were classified on the basis of diagnosis as MPE (n?=?56) and BPE (n?=?52). The concentration of IL-17 was determined by enzyme-linked immunosorbent assay (ELISA). The CEA levels were also determined in all patients. A significant difference was observed in the levels of CEA (P?<?0.01) between MPE and BPE. The concentration of IL-17 in MPE was significantly higher compared to that in BPE (P?<?0.01). With a cutoff point of 15.7 pg/ml, IL-17 had a sensitivity of 76.8 % and a specificity of 80.8 % for differential diagnosis. The combined detection of IL-17 and CEA had a sensitivity of 96.4 % and a specificity of 92.3 % to distinguish MPE from BPE. The combined detection of IL-17 and CEA may be more valuable in the differential diagnosis between MPE and BPE.

Chromogranin A, neuron specific enolase, carcinoembryonic antigen, and hydroxyindole acetic acid evaluation in patients with neuroendocrine tumors.

BACKGROUND: Chromogranin A (CgA), neuron specific enolase (NSE), carcinoembryonic antigen (CEA), and urinary 5-hydroxyindole-3-acetic acid (5-HIAA) are the markers currently used in the diagnosis, prognosis, and follow-up of patients with neuroendocrine tumors (NETs). The authors examined the role of such biomarkers in a large series of patients with NETs. METHODS: One hundred and twenty-seven patients entered the study. Multiple blood and 24-hour urine specimens were assayed for biomarker quantitation. RESULTS: The accuracy of each marker was assessed in patients with (n = 106) and without (n = 21) disease. CgA proved to be the best marker (specificity of 85.7% and sensitivity of 67.9%). Patients with disease had significantly higher CgA and NSE levels compared with disease free patients (P = 0.00003 and P = 0.00240, respectively). NSE and 5-HIAA determination showed a very high specificity (100%) but a rather low sensitivity (32.9% and 35.1%, respectively). CEA was found to have little diagnostic value (sensitivity of 15.4%). CgA was the most sensitive marker for detecting patients with disseminated disease and 5-HIAA displayed the highest sensitivity in identifying syndromic patients. Tumor marker modifications were studied during follow-up. In particular, rises in CgA were associated with progressive disease in 83.3% of cases and stable CgA was associated with stable disease in 53.8% of cases. The relation between CgA modifications and liver lesions during follow-up also was studied; increases in CgA levels were associated with local progression in 100% of cases and stable marker levels were found in 68.7% of the patients with unchanged lesions. CONCLUSIONS: The results of the current study demonstrate that CgA has the highest accuracy and is the most reliable biomarker reflecting the clinical evolution of NETs.     

CYFRA 21-1 determination in patients with esophageal squamous cell carcinoma: clinical utility for detection of recurrences

BACKGROUND: While there are reports that CYFRA 21-1 is a useful tumor marker, to our knowledge the clinical utility of this marker to detect recurrences for squamous cell carcinoma of the esophagus has not been addressed. METHODS: By immunoradiometric assay, human serum levels of CYFRA 21-1, SCC antigen and CEA were measured in esophageal squamous cell carcinoma patients prior to their initial treatment. Monthly follow-ups of these tumor markers was done after surgery. RESULTS: The diagnostic sensitivity of CYFRA 21-1 was 43.9% (18 of 41), a value superior to that for SCC antigen (26.8%) and CEA (17.0%) (P < 0.05). The positive rates of CYFRA 21-1 increased with progression of the disease, 22.2% of pTNM Stage 0-IIA and 77.8% of pTNM Stage IIB/III (P = 0.013), whereas SCC antigen and CEA rates were not related to pTNM stage. Among 13 patients with clinical evidence of a recurrence, 76.9% (10 of 13) exhibited an increase in CYFRA 21-1, and this increase was evident before clinical detection of the recurrence in 9 of these 13 patients (69.2%). Consequently, postoperative elevations of serum CYFRA 21-1 levels were indicative of a tumor recurrence 1-13 months before acquisition of clinical and radiological data. CONCLUSIONS: The assay of CYFRA 21-1 is useful not only for diagnosis but also for close monitoring of patients with esophageal squamous cell carcinoma.     

Cyfra 21-1, neuron specific enolase and prognosis of non-small cell lung cancer: prospective study in 621 patients

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.     

血清细胞角蛋白19片段抗原21-1、神经元特异性烯醇化酶在结肠癌中的表达情况及与预后的关系

目的 探讨血清细胞角蛋白19片段抗原21-1(CYFRA21-1)、神经元特异性烯醇化酶(NSE)在结肠癌中的表达情况及与预后关系.方法 检测78例结肠癌患者手术前后CYFRA21-1、NSE的表达水平,术后进行为期1年的随访,统计复发转移情况,比较不同临床特征结肠癌患者术后的血清CYFRA21-1、NSE表达水平,分析影响结肠癌患者术后复发转移的危险因素.结果 结肠癌患者术后血清CYFRA21-1、NSE水平均明显低于手术前(P﹤0.01).术后随访1年,有复发转移25例(32.05%),无复发转移53例(67.95%).单因素分析结果显示,淋巴结转移情况、分化程度、CYFRA21-1水平、NSE水平均可能是结肠癌患者术后复发转移的影响因素(P﹤0.05),肿瘤部位、性别、年龄、饮酒史、吸烟史均可能不是结肠癌患者术后复发转移的影响因素(P﹥0.05).将可能的影响因素带入Logistic回归模型进一步分析,结果显示,有淋巴结转移、分化程度低、术后CYFRA21-1高表达及NSE高表达均是结肠癌患者术后发生复发转移的危险因素(P﹤0.01).结论 血清CYFRA21-1、NSE水平在结肠癌患者中呈高表达,术后血清CYFRA21-1、NSE表达水平则明显下降,且血清CYFRA21-1、NSE表达与患者术后复发转移关系密切,对判断患者预后有重要临床价值.     

血清标志物CYFRA21-1、NSE、CEA、CA19-9、CA125、SCC联合检测在肺癌诊断中的应用价值

背景与目的:肿瘤标志物检测在肿瘤血清学诊断中被广泛的使用,但单个肿瘤标志物的阳性诊断率不高.本实验探讨肿瘤标志物CYFRA21-1、NSE、CEA、CA19-9、CA125、SCC在肺癌患者血清中的水平,及其在肺癌鉴别诊断中的价值.方法:采用化学发光法对135例肺癌组和30例健康体检组6项肿瘤标志物的含量进行检测及比较.结果:CYFRA21-1、NSE、CEA、CA19-9、CA125、SCC 6项肿瘤标志物肺癌组水平浓度分别为分别为(7±8)ng/ml、(30±29)ng/ml、(65±293)ng/ml、(110±379)U/ml、(122±412)U/ml、(2±7)ng/ml,显著高于正常对照组(P<0.01),其测定水平与病理类型有关.CEA在腺癌、鳞癌、小细胞癌水平浓度分别为(11±25)×10ng/ml、(2±4)×10ng/ml、(2±3)×10ng/ml;CA125在腺癌、鳞癌、小细胞癌水平浓度分别为(21±48)×10U/ml、(5±6)×10U/ml、(5±4)×10U/ml.CA19-9在腺癌、鳞癌、小细胞癌水平浓度分别为(17±44)×10U/ml、(5±12)×10U/ml、(4±4)×10U/ml.CEA、CA125、CA19-9在腺癌中水平显著高于鳞癌和小细胞癌(P<0.05).NSE、CYFRA21-1、SCC以鳞癌最高其水平浓度分别为(31±36)ng/ml、(8±10)ng/ml、(3±10)ng/ml,但与其他肺癌类型相比,差异均无显著性(P>0.05);SCC在腺癌、鳞癌、小细胞癌的阳性率分别为19.23%、29.78%、17.65%.结论:6项肿瘤标志物对肺癌的检测都有一定意义,不同病理类型各有特点,选择合适的组合检测可以有利于肺癌的鉴别诊断.     

Prognostic value of serum thymidine kinase, tissue polypeptide antigen and neuron specific enolase in patients with small cell lung cancer.

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.
