Tumour markers in gynaecologic oncology
1Department of Obstetrics and Gynecology, Regional and University Hospital, Trondheim, Norway.
Summary
Tumour markers like human chorionic gonadotropin and CA125 are vital in gynaecologic oncology for monitoring disease. While CA125 is widely used for ovarian cancer, its screening utility improves with combined diagnostic methods.
Area of Science:
- Gynaecologic Oncology
- Tumour Marker Detection
- Clinical Chemistry
Background:
- Tumour markers are crucial for diagnosing and monitoring gynaecologic cancers.
- Specific markers like human chorionic gonadotropin (hCG) and alpha-fetoprotein (AFP) are associated with gestational trophoblastic disease and germ cell tumours, respectively.
- Carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen aid in differentiating cervical and endometrial cancers and detecting recurrence.
Purpose of the Study:
- To review the utility of various tumour markers in gynaecologic oncology.
- To highlight the role of CA125 in epithelial ovarian carcinoma management.
- To assess the diagnostic and monitoring capabilities of different tumour markers.
Main Methods:
- Review of established tumour markers including hCG, AFP, squamous cell carcinoma antigen, CEA, and CA125.
- Analysis of marker specificity and sensitivity in gynaecologic malignancies.
- Evaluation of CA125's role in ovarian cancer monitoring and screening.
Main Results:
- hCG is a sensitive marker for gestational trophoblastic disease.
- AFP is reliable for endodermal sinus tumours and embryonal carcinomas.
- CA125 is the primary marker for epithelial ovarian carcinomas, essential for monitoring but not preoperative diagnosis.
- CA125's screening effectiveness increases when combined with pelvic examination and ultrasound.
Conclusions:
- Tumour markers play a significant role in the management of gynaecologic cancers.
- CA125 remains the most utilized marker in gynaecologic oncology, particularly for ovarian cancer monitoring.
- No combination of tumour markers has surpassed CA125 alone for its established applications.
