CYFRA 21-1 (lungs)

CYFRA 21-1 is a specific tumor marker used in the diagnosis and monitoring of non-small cell lung cancer. This analysis, which can be done within the private laboratory in Belgrade, IntroLab, is of essential importance to the medical community and patients, as it provides valuable information about the disease status, the effectiveness of therapy, and possible recurrences.

What is CYFRA 21-1?

CYFRA 21-1 is a fragment of cytokeratin 19, a protein present in the epithelium. When cancer cells form and develop, their levels in the blood may increase. This analysis is particularly useful for non-small cell lung cancer but can also be used to monitor some forms of urological, gynecological, and gastrointestinal tumors.

Why is measuring CYFRA 21-1 important?

Measuring the levels of this tumor marker in the blood can help in monitoring the response to therapy in patients with non-small cell lung cancer. It can also be useful in detecting disease recurrence and in making a diagnosis.

Who is the analysis indicated for?

This blood analysis is recommended for individuals diagnosed with non-small cell lung cancer. It is usually performed before the start of therapy and periodically during treatment to assess the body’s response to the treatment.

How are the results interpreted?

Results should be interpreted in the context of the patient’s overall clinical picture, including other laboratory findings and diagnostic procedures. Independent interpretation of the results of this tumor marker can be erroneous and potentially harmful.

What do the results indicate?

High levels of CYFRA 21-1 may indicate the presence of non-small cell lung cancer or other types of tumors. However, it is important to note that elevated levels of this marker do not necessarily mean that a person has cancer. Also, if periodic measurements of this tumor marker show a decrease, it may indicate that the therapy is effective.

How is the analysis performed?

The analysis requires a serum sample obtained from venous blood. No special preparation for blood draw is needed, but it is recommended that the sample not be taken immediately after eating.
