Use of Ovarian Tumor Markers in Prediction of Malignancy Risk in Pediatric and Adolescent Patients

Topic overview

Multi-institutional study of 309 pediatric/adolescent patients evaluated preoperative tumor marker combinations for predicting ovarian mass malignancy. β-HCG combined with AFP/CA-125/inhibin A achieved 100% negative predictive value, enabling safer identification of candidates for ovary-sparing surgery and reducing unnecessary oophorectomy for benign disease.

Key takeaways

  • β-HCG was present in all best-performing tumor marker combinations for predicting ovarian malignancy in pediatric patients.
  • The combination of AFP/β-HCG/CA-125/inhibin A achieved 100% negative predictive value, ensuring no malignancies were missed.
  • β-HCG/inhibin A/LDH combination showed highest overall accuracy (95.1%) for malignancy risk stratification.
  • Appropriate tumor marker selection can guide ovary-sparing surgery decisions and reduce unnecessary oophorectomies for benign disease.
  • Multi-marker panels outperform individual tumor markers in preoperative risk assessment of pediatric ovarian masses.
