Carcinoembryonic antigen (CEA) describes a set of highly-related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2]
Laboratory tumor lysis syndrome: abnormality in two or more of the following, occurring within three days before or seven days after chemotherapy. uric acid > 8 mg/dL or 25% increase; potassium > 6 meq/L or 25% increase; phosphate > 4.5 mg/dL or 25% increase; calcium < 7 mg/dL or 25% decrease
When a malignant tumor is found by the presence of a tumor marker, the level of marker found in the body can be monitored to determine the state of the tumor and how it responds to treatment. If the quantity stays the same during treatment it can indicate that the treatment isn't working, and an alternative treatment should be considered.

It can also be increased in pregnant women. Because of the wide variety of conditions that can increase serum levels, CA-125 is not used to detect cancer, but it is often used to monitor responses to chemotherapy, relapse, and disease progression in ovarian cancer patients. [20]
CA-125 levels in premenopausal women over 200 U/mL may indicate ovarian cancer, as may any elevation in CA-125 above 35 U/mL in post-menopausal women. CA-125 levels are not accurate in early stage ovarian cancer, as half of stage I ovarian cancer patients have a normal CA-125 level.
In the prefrontal cortex, this treatment resulted in an increase of the oxidative DNA damage 8-oxodG, a decrease in the enzyme OGG1 that ordinarily repairs such damage, and an increase in epigenetic alterations. These alterations, at the DNA level, may explain, at least in part, the impairments of cognitive function after chemotherapy. [23]
