Cancer antigen 125 (CA125) levels are elevated in women with advanced endometriosis, suggesting it may help diagnose endometriotic disease. However, CA125 is not a reliable marker for minimal or mild endometriosis.

Area of Science:

  • Gynecology
  • Reproductive Medicine
  • Biomarker Research

Background:

  • CA125 is a tumor marker primarily associated with ovarian cancer.
  • In healthy women, CA125 levels fluctuate with the menstrual cycle and can increase due to peritoneal irritation.
  • The endometrium and peritoneum are considered primary sources of CA125 in non-pregnant, non-diseased states.

Purpose of the Study:

  • To review the existing literature on the relationship between CA125 and endometriosis.
  • To evaluate the utility of CA125 as a diagnostic and monitoring tool for endometriosis.
  • To differentiate the role of CA125 in minimal/mild endometriosis versus advanced forms ('endometriotic disease').

Main Methods:

  • Literature review of studies investigating CA125 levels in women with and without endometriosis.

Related Experiment Videos

  • Analysis of CA125 concentrations in plasma and peritoneal fluid.
  • Correlation of CA125 levels with different stages and types of endometriosis.

    • Main Results:

    • Plasma CA125 is significantly elevated in cystic ovarian endometriosis and deeply infiltrating endometriosis.
    • CA125 levels are not significantly elevated in minimal or mild endometriosis, especially during the luteal phase.
    • Elevated CA125 post-treatment may indicate incomplete therapy or recurrence.
    • Assaying CA125 in peritoneal fluid remains challenging and of questionable clinical value.

    Conclusions:

    • CA125 is not a suitable standalone marker for diagnosing all forms of endometriosis.
    • CA125 can serve as a helpful supplementary parameter for diagnosing advanced endometriotic disease, particularly in patients with chronic pelvic pain.
    • Monitoring CA125 levels may aid in assessing treatment effectiveness and detecting recurrence of endometriotic disease.
