Background: A fragment of cytokeratin 19, referred to as CYFRA 21-1, is abundant in the serum of many patients with malignant tumors
and is recognized as one of the established tumor markers, especially for non-small-cell lung cancer. In this study, the clinical
usefulness of CYFRA 21-1 was investigated in cervical cancer patients treated with radiation therapy with reference to squamous-cell-carcinoma-related
antigen (SCC-Ag), a common tumor marker of cervical squamous cell carcinoma. Materials and methods: The serum levels of CYFRA 21-1 and SCC-Ag of 50 patients with squamous cell carcinoma of the uterine cervix were measured
before and after radiation therapy. Results: CYFRA 21-1 was positive in 52% of the patients. The incidence increased with the stage of the cancer, and post-treatment
increases were a sign of disease progression. During radiation, serum levels of CYFRA 21-1 decreased significantly and reflected
the radiation effect well. In addition, CYFRA 21-1 was negative in all patients without distant metastasis at the end of radiation
therapy. Compared with SCC-Ag, patients were less often positive for CYFRA 21-1, but there was a statistically positive correlation
between the two markers (correlation matrix = 0.69). Conclusions: CYFRA 21-1 can be used in monitoring the outcome of patients with squamous cell carcinoma of the uterine cervix. It may be
particularly useful for patients without SCC-Ag.

OBJECTIVE: The diagnostic utility of the tumour marker CYFRA 21-1 in malignant pleural effusion is not yet clear. This study was designed to evaluate the diagnostic utility of serum and pleural fluid CYFRA 21-1 in malignant pleural effusion. METHODOLOGY: The validity of serum and pleural fluid CYFRA 21-1 was determined in 62 patients with exudative pleural effusion (27 malignant and 35 benign). The diagnosis of malignant pleural effusion was defined by cytological or histological results. RESULTS: A statistically significant difference between the geometric means of CYFRA 21-1 levels in pleural fluid of benign and malignant aetiologies was observed (11.2 vs 63.3 ng/mL, P < 0.0001). In addition, there was a significant difference in the serum levels (0.95 vs 5.55 ng/mL, P < 0.0001). The sensitivity and specificity of pleural fluid CYFRA 21-1 in malignant pleural effusion, at the cut-off value of 55 ng/mL, was 74.1% and 97.1%, respectively. The sensitivity and specificity of serum CYFRA 21-1, at the cut-off value of 2.5 ng/mL, was 81.5% and 97.1%, respectively. Using a combination of serum and pleural fluid CYFRA 21-1 level, the sensitivity increased to 88.9%. CONCLUSION: Serum and pleural fluid CYFRA 21-1 are useful as measures in differentiating malignant from benign pleural effusion. 相似文献

目的确定我国肺癌患者血清细胞角蛋白19片段(CYFRA21-1)浓度阈值,探讨其临床应用价值。方法应用单克隆抗体(Ks19.1和BM19.21)检测72例初次确诊肺癌患者和50例肺良性疾病患者以及33例治疗后肺癌患者血清CYFRA21-1水平。采用ROC曲线确定CYFRA21-1浓度阈值。结果(1)肺癌患者血清CYFRA21-1水平显著高于肺良性疾病患者(P<0.001),鳞癌显著高于其它病理类型,且其浓度随临床分期升高而升高。(2)当阈值定为5.5μg/L时,CYFRA21-1检测肺癌的敏感性、特异性分别为63%和94%。鳞癌敏感性最高为78%。(3)CYFRA21-1检测非小细胞肺癌的敏感性随临床分期升高而升高。(4)CYFRA21-1是监测肺癌病情、提示疗效的良好指标。(5)当CYFRA21-1作为筛检肺癌的指标时,阈值宜取非小细胞肺癌I-II期ROC曲线拐点,但对非小细胞肺癌早期诊断作用有限。结论CYFRA21-1是一较好的非小细胞肺癌肿瘤标记物,尤其适用于肺鳞癌 相似文献

Serum CYFRA 21-1 level reflects hepatocellular carcinoma metastasis: study in nude mice model and clinical patients 总被引:14,自引:0,他引:14

Our previous proteomics study on human hepatocellular carcinoma (HCC) cell strains revealed that cytokeratin 19 (CK19) was expressed in cells with high metastasis potential; we further studied serum CK19 fragment CYFRA 21-1 level in HCC patients and nude mice model of HCC metastasis. HCC cell line HCCLM3 was injected subcutaneously into 30 nude mice which were then randomized into 6 groups of 5 mice each. The murine serum CYFRA 21-1 and pulmonary metastases were determined 2, 3, 4, 5, 6, and 7 weeks after injection. Serum CYFRA 21-1 levels of 101 normal controls and 108 HCC patients were also determined. In nude mice model, CYFRA 21-1 level increased significantly when pulmonary metastases occurred. Among 108 HCC patients, 24 (22.2%) had increased serum CYFRA 21-1 level. The presence of portal vein tumor emboli was significantly higher in CYFRA 21-1 increased cases (33.3%, 6/24) than in CYFRA 21-1 normal cases (6.0%, 5/84) (x
2 = 7.403, P < 0.01). In addition, the percentage of TNM stage III/IV tumor was significantly higher in CYFRA 21-1 increased patients (54.2%, 13/24) than in CYFRA 21-1 normal cases (21.4%, 18/84) (x
2 = 9.776, P < 0.005). These results suggest that CK19 may play an important role in HCC metastasis. 相似文献

CYFRA 21-1 is a fragment of cytokeratin 19 (CK 19). Four patients with large intrahepatic (or peripheral) cholangiocarcinoma
(CC) and high serum levels of CYFRA 21-1 (normal, ≤2 ng/ml) are reported. CYFRA 21-1 levels exceeded 9 ng/ml in all 4 patients.
Carcinoembryonic antigen (CEA), was high in 1 (CEA; normal range, ≤5.0 ng/ml) and carbohydrate antigen 19-9 (CA 19-9) was
high in 3 (CA19-9; normal range, ≤36 U/ml). We also measured serum levels of CYFRA 21-1 in 13 patients with hepatocellular
carcinoma (HCC) more than 5 cm in diameter. Levels of CYFRA 21-1 exceeded 2 ng/ml in 9 of the HCC patients and were higher
than 9 ng/ml in 2 of the HCC patients. Levels of alpha fetoprotein (AFP) and/or protein induced by vitamin K absence or antagonist
II (PIVKA II) were elevated in all HCC patients (AFP, PIVKA II, respectively; normal range, ≤10.0 ng/ml and ≤0.1 AU/ml) CYFRA
21-1 levels were measured twice or three times during the clinical course in 2 CC patients and in 6 HCC patients, and increased
gradually with tumor growth in the 2 CC patients and in 3 of the 6 HCC patients. Marked increases in serum CYFRA 21-1 levels
in patients with large liver cancers, particularly in those with normal levels of AFP and PIVKA II, would suggest the existence
of intrahepatic CC rather than HCC.

Cytokeratin Fragment 19 (CYFRA 21-1) and Carcinoembryonic Antigen for Early Prediction of Recurrence of Lung Adenocarcinoma 总被引:1,自引:0,他引:1
Fifty patients with adenocarcinoma of the lung were enrolled in this study, including 20 patients with recurrence and 30
patients without recurrence 1 year after surgery. Serial serum levels of cytokeratin fragment 19 (CYFRA 21-1) and carcinoembryonic
antigen (CEA) were measured before the operation and 1 week, 1 month, 3 months, 6 months, 9 months, and 12 months after surgery
for the early detection of recurrence. The results revealed that the mean serum values of either CYFRA 21-1 or CEA were significantly
higher until 9 and 12 months after surgery in the 20 patients with recurrent adenocarcinoma compared with the 30 patients
without recurrent adenocarcinoma. We conclude that CYFRA 21-1 is not a better marker than CEA for early prediction of adenocarcinoma.
We conclude that CYFRA 21-1 is not a better marker than CEA for early prediction of adenocarcinoma recurrence in lung.
