Product Description

Breast cancer is the most common life-threatening malignant lesion in women of developed countriestoday, with approximately 180,000 new cases diagnosed every year. Roughly half of these newlydiagnosed patients are node-negative, however 30% of these cases progress to metastatic disease.There are a number of tumor markers that can help clinicians to identify and diagnose which breast cancerpatients will have a more aggressive disease. These markers include estrogen and progesteronereceptors, DNA ploidy and percent-S phase profile, epidermal growth factor receptor, HER-2/neuoncogene, p53 tumor suppressor gene, cathepsin D, proliferation markers and CA15-3. CA15-3 is mostuseful for monitoring patients post-operatively for recurrence, particularly in metastatic disease cases.96% of patients with local and systemic recurrence have elevated CA15-3, which can be used to predictrecurrence earlier than radiological and clinical criteria. A 25% increase in the serum CA15-3 is associatedwith progression of carcinoma. A 50% decrease in serum CA15-3 is associated with response totreatment. CA15-3 is more sensitive than CEA in early detection of breast cancer recurrence. Incombination with CA125, CA15-3 has been shown to be useful in early detection of relapse of ovariancancer. CA15-3 levels are also increased in colon, lung and hepatic tumors.
