- elevated level of preoperative serum Cyfra 21-1 indicates an advanced stage of tumor PMID: 30037371
- CYFRA 21-1 assessed at the end of RT or ChT seems to be a prognostic marker for tumor response. A high concentration of CYFRA 21-1 after treatment increases the risk of death. CYFRA 21-1 might be suggested in the monitoring of carcinomas of head and neck cancer (HNC). PMID: 28604997
- the modulation of KRT19 expression could be involved in cancer stem cell reprogramming and drug sensitivity. PMID: 29747452
- High expression of CK-19 is associated with intrahepatic cholangiocarcinoma. PMID: 29513894
- KRT19 intracellularly binds to HER2, playing a critical role in HER2 activation PMID: 28008968
- The combined use of CK19 and CD56 is helpful in discriminating papillary thyroid carcinoma and its variants from other mimicking thyroid lesions. PMID: 28214214
- CYFRA 21-1 can be useful as a tumor marker for evaluating tumor progression and treatment efficacy in patients with extramammary Paget's disease. PMID: 28150330
- YAP1 activation was more commonly found in CCAs than in pure HCCs. However, a differing pattern of YAP1 expression between cHC-CCAs and CK19(+) HCCs and the poor prognosis of YAP1 positive hepatic carcinomas suggests that YAP1 may have a preferential role in aggressive tumor behavior, rather than in the determination of cellular lineage in hepatic carcinomas PMID: 28645247
- Circulating tumor cells expressing cytokeratin and tumor-initiating cell markers, including ALDH, CD133, and CD44, were identified in patients with pancreatic adenocarcinoma. These TIC-like CTCs were associated with poor prognosis after surgical resection and with an increased incidence of tumor recurrence PMID: 27789528

- Urine levels of COL4A1, COL13A1, the combined values of COL4A1 and COL13A1 (COL4A1 + COL13A1), and CYFRA21-1 were significantly elevated in urine from patients with BCa compared to the controls. A high urinary COL4A1 + COL13A1 was found to be an independent risk factor for intravesical recurrence. PMID: 28837258
- CK19 and carcinoembryonic antigen may be involved in lymph node metastasis and poor prognosis in patients with gastriccardia cancer PMID: 28293089
- The study has confirmed the preservation of CK19 protein expression in breast cancer cells after neoadjuvant therapy. On the basis of these results, quantification-based methods such as the one-step nucleic acid amplification (OSNA) CK19 assay, could be an accurate tool with which to analyse the sentinel nodes, regardless of whether they had been obtained before or after treatment. PMID: 26708058

- Results suggest that positive expression of CK19 mRNA and TK1 protein is closely correlated with poor prognosis in advanced gastrointestinal cancer. PMID: 27625087
- GPC3 and KRT19 overexpression are associated with carcinogenesis, progression, and poor prognosis in patients with PDAC and a valuable biomarker for diagnosis of PDAC. PMID: 27689616
- Data show that sixty one patients with a high cytokeratin 19 fragment (CYFRA 21-1) level had statistically shorter progression-free and overall survival than 39 patients with a normal CYFRA 21-1 level . PMID: 28179355
- Data indicate that serum tumor markers showed significant shorter 3-year progression-free survival (PFS) in higher levels compared to lower levels for S-CYFRA 21-1 (cytokeratin 19 fragment), S-SCCA and S-CEA. PMID: 26432331
- Gene promoter hypermethylation is found in sentinel lymph nodes of breast cancer patients identified as positive by one-step nucleic acid amplification of cytokeratin 19 mRNA PMID: 27097811

- BALF and serum NSE, CEA, and CYFRA21.1 elevated in lung cancer, which had prompt value for pathology, especially significant for BALF. PMID: 27072263
- Significant levels of CEA, CYFRA 21-1, NSE, and TSGF were detected in the serum. The amounts found were useful for diagnosing non-small cell lung cancer (NSCLC) patients who depended on the currently limited biomarker development. PMID: 27072222
- The cytologic tumor marker c-CYFRA was positively associated with EGFR mutations in non-small cell lung cancer (NSCLC). EGFR mutation-positive NSCLCs have relatively lower glycolysis compared with NSCLCs without EGFR mutation PMID: 26979333
- Results show that serum miR21 could serve as an important marker for auxiliary diagnosis of early non-small cell lung cancer (NSCLC), while joint detection of serums miR21 and CYFRA21-1 levels could improve diagnostic efficiency. PMID: 26880855
- Positive staining for CK19 suggests a possible LPC origin of the EpCAM positive hepatocellular carcinoma . PMID: 26609030
- Increased Expression of K19 mRNA is associated with Recurrence After Curative Resection of Hepatocellular Carcinoma. PMID: 25791790

- Elevation of serum CYFRA21-1 is associated with Non-small Cell Lung Cancer. PMID: 26163610
