Serum CA19-9 CA-125 and CEA as tumor markers for mucinous ovarian tumors Serum CA19-9 CA-125 and CEA as tumor markers for mucinous ovarian tumors J Obstet Gynaecol Res.

The usefulness of a tumor marker is in its sensitivity and specificity as well as its influence on patient management decisions. Serous is the most frequent histological subtype of ovarian carcinoma and makes up 30-70 of all diagnoses. And beta-2-microglobulin measured in blood urine or cerebrospinal fluid to estimate prognosis and follow response to treatment for multiple myeloma.

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 whether it can be treated with a targeted therapy or whether it is responding to treatment. CA 125 is a protein that is a so-called tumor marker or biomarker which is a substance that is found in greater concentration in tumor cells than in other cells of the body. Aid in making diagnosis.

Afetoprotein and human v chorionic gonadotrophin are probably the best known tumor markers in clinical practice and are invaluable in the diagnosis treatment and followup of ovarian germ cell tumors. The use of the cancer antigen 125 Ca125 tumour marker can be unreliable in premenopausal women given the low sensitivity for ovarian cancer.

Particularly large masses tend to be benign or borderline. A detailed discussion of tumor markers in ovarian germ cell tumors is beyond the scope of this review and is outlined in Table 5. Normal range may vary somewhat according to institutional experience.
