CA-125 referral
Is Elevated CA-125 Enough for Gynecologic Oncology Referral?
A concise clinician guide for interpreting CA-125 in consult decisions.
Quick answer
CA-125 Referral
- CA-125 alone is usually not a tissue diagnosis or standalone consult reason.
- CA-125 becomes more actionable with high-risk imaging, concerning exam, menopausal status, symptoms, or pathology. †
- Workup-first cases need imaging, exam, sampling, records, or contextual labs before Gyn Onc can answer the right question.
Consult Gyn Onc when
Actionable CA-125 Context
- Elevated CA-125 plus high-risk adnexal imaging or metastatic pattern. *†
- Elevated CA-125 plus confirmed gynecologic malignancy.
- The consult question is staging, oncologic surgery, neoadjuvant therapy, biopsy route, or disposition.
Workup first when
Better First Steps
- CA-125 is elevated without high-risk imaging or tissue diagnosis.
- There are plausible non-malignant explanations and the next step is risk stratification.
- The question is whether a lab is abnormal, not what oncologic decision changes today.
Common pitfall
A Tumor Marker Is Not a Diagnosis
CA-125 is context. The consult gets cleaner when paired with imaging, exam, pathology, or a specific decision Gyn Onc can change.
FAQ
CA-125 Questions
Is CA-125 specific for ovarian cancer?
No. Interpret it with imaging, exam, menopausal status, symptoms, and pathology. †
Should I consult Gyn Onc for CA-125 elevation alone?
Usually no. If imaging and pathology are not concerning, the next step is often workup or risk stratification first.
What should be pending before I call Gyn Onc?
Helpful pending items include pelvic US/O-RADS, pathology, tumor markers, outside records, and the specific disposition or management question.
