A list of tumor marker tests that are in common use, mainly to direct treatment or for testing in blood to help make a diagnosis of cancer.

A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain benign (noncancerous) conditions that provides information about a cancer, such as how aggressive it is, what kind of treatment it may respond to, or whether it is responding to treatment.

Tumor Markers Key Information. For baseline and observation — to assess tumor burden and monitor levels of tumor and indicate a recurrence; prognosis (what treatment to use if the tumor should recur); most tumor markers are NOT specific, meaning that positive result does not necessarily mean that the primary site can be readily identified ...

Persistent elevated levels indicate residual or recurrent metastatic carcinoma.

2024年3月4日 · Tumor markers are tumor-specific substances in the blood serum or other tissues that can assist in determining the presence or absence of cancer. They can help determine the initial tumor burden in both the primary site and distant sites.

A substance found in tissue, blood, bone marrow, or other body fluids that may be a sign of cancer or certain benign (noncancer) conditions. Many tumor markers are proteins made by both normal cells and cancer cells, but they are made in higher amounts by cancer cells.

2023年1月17日 · Tumor marker tests. What they do: Tests for tumor markers measure substances that are produced by cancer cells or other cells of the body in response to cancer. Most tumor markers are made by both normal cells and cancer cells. But they are produced at much higher levels by cancer cells.

Tumor Markers. No tumor marker is of value in diagnosing melanoma of the skin and there are no markers used to detect for advanced disease. However, there are some promising markers currently being studied: TA-90. TA-90 is a tumor-associated antigen first identified in the urine and sera of patients with metastatic melanoma.

Tumor Markers Key Information. Prognostic (what treatment to use if the tumor should recur) Acid Phosphatase: Also called: acid phos, acid f, acid p'tase. A test of blood serum to detect a specific enzyme produced by several tissues, particularly the prostate.
