Purpose In current studies, the role of serum Cytokeratin-19 fragments (CYFRA 21-1) in
colorectal cancer (CRC) remains unclear. This study aimed to clarify the diagnostic and …

Serum CYFRA21-1 levels were studied in 127 cases of colorectal cancer. The positive rates
for serum CYFRA21-1 were 34.6% in primary colorectal cancer. There was a significant …

Background Biliary tract cancers encompass gallbladder carcinoma, and intrahepatic,
perihilar and distal cholangiocarcinoma. Upregulated serum CYFRA 21-1 has been …

Purpose Among diverse tumor markers, pretreatment evaluation and follow-up detection of
recurrence in colorectal cancer are generally evaluated by serum carcinoembryonic antigen …

BACKGROUND: CYFRA 21-1 has been reported as a useful tumor marker for esophageal
carcinoma, but little information was reported about the clinicopathologic importance of …

Abstract Purpose Cytokeratin 19 fragment 21–1 (CYFRA 21–1) and cytokeratin 19 fragment
2G2 (CK 19-2G2) are two soluble fragments of cytokeratin 19 (CK 19) that can be detected …

Objective To study the clinical significance of the novel tumor marker--CYFRA21-1 in
patients with esophageal cancer. Methods The CYFRA21-1 level in serum of 84 patients …

Our previous proteomics study on human hepatocellular carcinoma (HCC) cell strains
revealed that cytokeratin 19 (CK19) was expressed in cells with high metastasis potential; …

Background Biliary tract cancer (BTC) has a poor prognosis, in part related to difficulties in
diagnosis. Cytokeratin 19 (CK19) is a constituent of the intermediate filament proteins of …

BACKGROUND: High preoperative serum CYFRA 21-1 has been reported as diagnostic
marker and poor prognostic factor in non-small cell lung cancer, especially in squamous cell …
