What does hCG stand for in serum tumor markers?

The abbreviation hCG stands for human chorionic gonadotropin. This is a hormone produced during pregnancy, primarily by the placenta, but it is also present in certain types of tumors, making it a valuable serum tumor marker. Elevated levels of hCG can be indicative of specific cancers, including gestational trophoblastic disease and some gonadal cancers, as it is part of the body's response to certain malignancies. Its role in oncology primarily revolves around its use in diagnosis and monitoring of cancer progression and treatment response, particularly in cancers that can secrete this hormone.

Understanding the function and significance of hCG as a tumor marker helps oncology data specialists in interpreting laboratory results and making decisions regarding patient care and treatment plans.
