Cyfra21-1
Supporting to diagnose Non-Small-Cell Lung Cancer (NSCLC)
Cyfra21-1 belongs to a cytokeratin family, which is normally expressed in epithelial tissues and forms the epithelial cells’ filament cytoskeleton and it can be used as a circulating tumor marker. Although expressed in all body tissues, its major occurrence is in the lung, particularly in lung cancer tissues, so it is a sensitive, specific, and valuable biomarker for estimation of diagnosis, prognosis, and therapy monitoring of non-small-cell lung cancer (NSCLC), especially of squamous cell subtype.

In Your Medical Field
Lung cancer is the No.1 most common cancer in the world. It is by far the leading cause of cancer death, making up almost 25% of all cancer deaths. If lung cancer is detected at an early stage, the 5-year survival rate is more than 80%, so early detection and diagnosis is urgent for the sake of an effective treatment strategy for lung cancer. Cyfra21-1 is useful for detecting disease relapse, assessing surgical chemotherapeutic efficacy, predicting very advanced cases and overall prognosis of lung cancer.
