Unlocking Diagnostic AccuracyEvaluating Imaging and Tumor Markers for Ovarian Teratomas

Introduction

Mature cystic teratomas (MCTs) are the most frequent benign ovarian tumors in women of reproductive age. This study dives deep into the predictive strength of preoperative diagnostic tools like ultrasonography, CT, MRI, and tumor markers to identify MCTs accurately before surgical intervention.

Key Highlights of the Research

This retrospective analysis examined 136 patients diagnosed with ovarian MCTs. Findings revealed:

• Ultrasonography was used in 119 patients with a sensitivity of 67.2%.
• CT scans were more accurate with 78.8% sensitivity, detecting key features like fat density and Rokitansky nodules.
• MRI, while slightly less sensitive (70.6%), provided valuable soft tissue detail and was especially helpful in complex cases.
• Among tumor markers, CA 19-9 showed the highest sensitivity at 31%, outperforming CA 125 (16%), CA 15-3 (10.7%), and AFP (6%).

Notably, tumor markers were less reliable than imaging techniques, reinforcing the need for comprehensive radiologic assessment.

Why This Matters for Women’s Health

Early detection of MCTs is vital to avoid complications like torsion, rupture, or in rare cases, malignant transformation. Since many cases are asymptomatic, accurate imaging plays a critical role in diagnosis and surgical planning.

The American College of Obstetricians and Gynecologists (ACOG) emphasizes timely identification of ovarian masses, especially in reproductive-aged women, to safeguard fertility and prevent emergent complications.

Study Findings in Brief

• Total patients: 136
• Correct preoperative diagnosis: 103 cases (75.7% sensitivity with imaging)
• Tumor marker CA 19-9: Most predictive, especially in larger tumors
• Ultrasound signs: Hyperechoic nodules, acoustic shadowing, mixed echogenicity

Key Takeaways:

• Imaging techniques outperform tumor markers for preoperative diagnosis.
• CT and MRI provide enhanced detection, especially in ambiguous ultrasound findings.
• Tumor markers should be used as supplementary tools, not sole diagnostic indicators.
