CA125 - Ovarian Cancer marker

Useful for:

Evaluating patients' response to ovarian cancer therapy, predicting recurrent ovarian cancer.
Elevated serum CA 125 levels are seen in mostly women with ovarian cancer. It has also been reported in certain non-ovarian malignancies and in benign conditions like cirrhosis, hepatitis, endometriosis, first trimester pregnancy, ovarian cysts, and pelvic inflammatory disease. Elevated levels during the menstrual cycle also have been reported.
Limitations:
Results cannot be interpreted as absolute evidence of the presence or absence of disease.Serum markers are not specific for malignancy and values may vary by method. Values obtained with different assay methods cannot be used interchangeably.
