An Assisted Diagnostic and Prognostic Model for Endometrial Cancer Using 36 Serological Markers and Clinical Variables from 562 Patients
Endometrial carcinoma (EC) incidence is rapidly increasing, yet current evaluation systems are limited to postoperative analysis. This research pioneers a machine learning-based approach using 36 serological markers and clinical variables to develop a powerful preoperative risk stratification model for EC diagnosis, staging, metastasis risk, and prognosis.

The study directly compared traditional logistic regression with various supervised machine learning models, demonstrating a significant leap in predictive power with ensemble methods like Random Forest.
Enhanced EC Diagnosis
Our model significantly improves the accuracy of distinguishing endometrial cancer from benign conditions preoperatively.
0.94
Preoperative Diagnostic Accuracy
The Random Forest classifier achieved a high predictive accuracy of 0.94 and an AUC of 0.81 for distinguishing EC from EAH, demonstrating its superior performance over traditional logistic regression methods.
The Random Forest classifier proved most effective, achieving remarkable accuracy in differentiating EC from endometrial atypical hyperplasia (EAH), a premalignant condition. Key predictors identified for this differentiation include Age, CA19-9, and Alkaline Phosphatase (ALP).
Advanced Prognostic Risk Stratification
Accurate preoperative prediction of EC prognosis, including staging and Mayo criteria, is critical for personalized treatment planning.
HE4
Most Important Prognostic Predictor
HE4 was consistently identified as the most important parameter for predicting Mayo criteria and prognostic risk groups for adjuvant therapy, highlighting its central role in preoperative prognosis.
The Random Forest model attained a predictive accuracy of 0.80 with an AUC of 0.78 for differentiating early-stage (I) from more advanced stages (II/III/IV) of EC. For Mayo criteria prediction, the model achieved an AUC of 0.71. These capabilities enable clinicians to make more informed decisions regarding surgical intervention and adjuvant therapies.
Crucial Serological Markers Identified
The study highlights the specific roles of HE4 and CA125 as highly significant serological markers for EC management.
Biomarker-Driven Precision
HE4 and CA125: Pillars of EC Prediction
Human epididymis protein 4 (HE4) emerged as a pivotal predictor for overall risk stratification, including clinical stages and Mayo criteria. Carbohydrate antigen 125 (CA125) proved most effective in detecting lymph node invasion. This targeted biomarker approach enables more personalized and early EC management, moving beyond invasive methods.
While HE4 is crucial for general risk stratification and Mayo criteria, CA125 shows strong correlations with lymphoid node metastasis, making it an excellent marker for identifying patients requiring lymph node dissection. This serum-based strategy offers a non-invasive complement to traditional invasive methods.
Future Directions and Limitations
While groundbreaking, this model presents clear avenues for future enhancement and broader applicability.
Addressing Current Limitations
Pathway to Enhanced Generalizability
Despite robust findings, the model acknowledges limitations such as being developed from a single-center cohort in South China, potentially leading to biased sample distribution. Future work will focus on expanding to multi-center data repositories and integrating multimodality models (e.g., radiogenomics) to enhance prediction efficacy and generalizability.
The current model provides a strong foundation, but further research is needed to validate its generalizability across diverse populations and to explore the integration of additional data types, such as radiomics and genomics, for even more comprehensive and precise predictions.
