Questions and Answers

Which of the following statements is true about β2-microglobulin?

It is associated with T-lymphocytes.

Its secretion decreases in tumor.

It is effective in renal diseases.

It is used as a tumor marker for B-lymphocyte malignancy provided renal function is normal. (correct)

Study Notes

Normal Cell Products

Markers Produced by Specific Cell Types

β2-microglobulin is a HLA-antigen associated protein normally present on the cell wall of B-lymphocytes.
It is used as a tumor marker for follow-up of malignancy of B-lymphocytes, such as lymphoma and leukemia.
Renal function affects β2-microglobulin levels, so normal renal function is required for accurate results.

Prostatic Specific Antigen (PSA)

PSA is normally confined to the epithelial tissue of the prostate.
It is used as a tumor marker in prostatic cancer for:
Screening, in conjunction with digital rectal examination.
Early detection, particularly by measuring free PSA or PSA density (PSA / prostate volume by ultrasound).
Follow-up.

Monoclonal Immunoglobulin

Monoclonal Immunoglobulin is used as a tumor marker for early detection and follow-up of multiple myeloma.

Markers Produced by Many Cells

Enzymes produced by tumors have low specificity and therefore limited clinical importance.
