Question

Dear OncoLink "Ask The Experts,"
I would like to ask three questions if I might:

  1. Is it unusual for post surgical CA125 to elevate after cancer surgery? My sister's CA125 was 33 preop and 60 three-days post op. Her diagnosis is: Endometrial Adenocarcinoma, Endometroid Type, plus focal squamous metaplasia arising in a focus of endometriosis, FIGO Grade 2.
  2. My sister has recently been diagnosed with pericardial effusion. Are there risks of toxicity in this fluid when she undergoes chemotherapy, which is scheduled alongside of her radiation therapy?
  3. Do fat cells produce estrogen, or do they just store this hormone and what causes the estrogen to be released from fat cells?
Her gynecologist placed her on Estratest patches approximately six months after her surgery. How long would it take for her body to flush out the hormones? 

Answer

Christina S. Chu, MD, Assistant Professor of the Division of Gynecologic Oncology at the University of Pennsylvania Health System, responds:

You have asked some very good questions. Let me address them one by one.

First, many things may affect CA125 measurement in the blood. Gynecologic reasons include cancers of the ovary and endometrium as well as infection, benign cysts, and fibroids. Many non-gynecologic factors influence CA125 as well, including surgery, cirrhosis, heart failure, and pericarditis. Given the circumstances of recent surgery and your sister's pericardial effusion, I do not think that this small rise in CA125 is unusual.

Second, various chemotherapies may affect the heart. Your sister needs to discuss with her physician whether the pericardial effusion is compromising her heart function first. Then, consideration should be given to the specific types of chemotherapy that may be administered. Taxol may occasionally slow the heartbeat, and adriamycin (also known as doxorubicin) may cause cumulative heart damage. Depending on the severity of the effusion, either drug may be administered safely, but the specifics should be discussed with your sister's treating physician.

Lastly, by this point, the estrogen received from the patch or pills should have been eliminated by the body. However, estrogen is produced by peripheral fat, so even post-menopausal women may have appreciable levels of estrogen hormones.
