Antigen-Down PEC Immunosensor for CYFRA21‑1 Detection Based on Photocurrent Polarity Switching Strategy

open access: yes, 2022
In this work, an antigen-down photoelectrochemical (PEC) immunosensor based on a signal polarity switching strategy for the detection of cytokeratin 19 fragment 21-1 (CYFRA21-1) was proposed.

Serum CYFRA21-1 as an effective tumor biomarker for patients with nasopharyngeal carcinoma

open access: yesNeoplasma, 2015
We investigated if the serum cytokeratin 19 fragment 21.1 (CYFRA21-1) level was elevated in nasopharyngeal carcinoma (NPC) and can function as a biomarker for detection and monitoring of NPC. Three hundred and one study subjects were divided into two groups: the NPC group (n=126) and healthy control group (n=175).

Serum cyfra21-1 as a biomarker in patients with nonsmall cell lung cancer

open access: yesJournal of Cancer Research and Therapeutics, 2014
The purpose of this retrospective study was to evaluate the clinical value of serum cytokeratin-19-fragment (cyfra21-1) as a biomarker in nonsmall cell lung cancer (NSCLC).Sixty-six patients with NSCLC and 48 cases with benign lung disease were retrospectively analyzed in the department of thoracic surgery in our hospital.

A Potential Serum Biomarker for Screening Lung Cancer Risk in High Level Environmental Radon Areas: A Pilot Study

open access: yesLife, 2021
Radon is a major cause of lung cancer (LC) deaths among non-smokers worldwide. However, no serum biomarker for screening of LC risk in high residential radon (HRR) areas is available. Therefore, the aim of this study was to determine diagnostic values of

CYFRA21-1 levels could be a biomarker for bladder cancer: a meta-analysis

open access: yesGenetics and Molecular Research, 2015
The proteolytic region of cytokeratin-19, referred to as CYFRA21-1, is a soluble molecule present in the serum and other body fluids, and is considered a tumor marker in several neoplastic diseases. To examine whether urinary or serum samples containing CYFRA21-1 can be used as biomarkers for bladder cancer, we conducted a comprehensive meta-analysis ...

Mechanisms of the release of CYFRA21-1 in human lung cancer cell lines

open access: yesLung Cancer, 2000
The CYFRA 21-1 assay which detects cytokeratin 19 (CK19) fragment is widely used as a tumor marker for lung cancer. However, the reason why some lung cancer cell lines release CK19 fragment in culture supernatants and others do not, remains unclear. It was hypothesized that the release of CK19 fragment may be elucidated by the expression of mRNA for ...

Growth Differentiation Factor 15 as a Cerebrospinal Fluid Biomarker for the Diagnosis and Prognosis of Leptomeningeal Metastasis

open access: yesAnnals of Neurology, EarlyView.
Objective As leptomeningeal metastasis (LM) has a poor prognosis, reliable cerebrospinal fluid (CSF) diagnostic biomarkers are urgently needed. This study evaluated the diagnostic value of CSF growth differentiation factor 15 (GDF15) in LM from lung adenocarcinoma (LUAD) and breast cancer (BC).
