Summary
A new model effectively distinguishes borderline from invasive ovarian tumors using menopausal status, cancer antigen 125 levels, and ultrasound findings. This tool aids initial ovarian tumor evaluation for clinicians and patients.
Area of Science:
- Gynecologic Oncology
- Medical Imaging
- Biomarkers
Background:
- Accurate differentiation between borderline and invasive ovarian tumors is crucial for appropriate patient management.
- Distinguishing these tumor types preoperatively can prevent unnecessary radical surgeries for benign conditions and guide timely treatment for malignant ones.
Purpose of the Study:
- To develop and validate a predictive model for differentiating borderline from invasive ovarian tumors.
- To identify key clinical, serological, and imaging parameters that contribute to this differentiation.
Main Methods:
- A retrospective analysis of 148 patients with borderline or invasive ovarian tumors was conducted.
- Clinical and pathological data were collected, and logistic regression was employed to construct the predictive model.
- Model performance was assessed using cross-validation.
Main Results:
- The developed model incorporates menopausal status, preoperative cancer antigen 125 levels, greatest tumor diameter, and ultrasound-identified solid components.
- The model demonstrated high sensitivity (94.6%) and specificity (78.3%) for patients aged ≥ 50 years.
- For patients aged < 50 years, the model achieved a sensitivity of 76.0% and specificity of 60.0%.
Conclusions:
- A predictive model integrating menopausal status, cancer antigen 125, and ultrasound parameters reliably differentiates borderline and invasive ovarian tumors.
- This model serves as a valuable tool for oncologists and patients during the initial assessment of ovarian tumors.
- The findings support the use of this model to improve preoperative diagnostic accuracy in ovarian oncology.
