HbA1c as a Key Metabolic Marker in Predicting Myomectomy Requirement in Women with Uterine Fibroids: A Machine Learning Study

This study demonstrates that HbA1c is significantly associated with myomectomy requirement in women with uterine fibroids at the univariate and machine learning levels, but its independent predictive value is confounded by iron-related parameters. Ferritin emerged as a robust independent predictor. Machine learning models integrating HbA1c, ferritin, hormonal, and fibroid-related features achieved high classification performance and 94% concordance with expert clinical judgment, suggesting HbA1c's role as an integrative marker within a comprehensive decision-support framework.

Uterine fibroids are common benign tumors often requiring surgical management. Metabolic dysfunction and insulin resistance, as indicated by HbA1c, have been implicated in fibroid biology. This study evaluates HbA1c's predictive role for myomectomy, leveraging both conventional statistics and machine learning under real-world clinical conditions. The analysis covers demographic, laboratory, hormonal, and fibroid-related variables in 618 women.

Key findings highlight significantly higher HbA1c levels in myomectomy patients. While HbA1c is strongly associated in univariate analysis, its independent significance is confounded by iron-related parameters, with ferritin emerging as a key independent predictor. Machine learning models incorporating HbA1c and other factors achieved high accuracy and expert concordance, positioning HbA1c as a valuable integrative marker within a comprehensive decision-support framework.

This retrospective multicenter cohort study included 618 women with uterine fibroids, stratified by myomectomy status (238 surgical, 380 non-surgical). Data included demographics, laboratory results (HbA1c, ferritin, hormones), and fibroid characteristics. The analytical strategy involved comparative analyses, univariate and multivariate logistic regression, and machine learning modeling.

A total of 155 machine learning models were trained, with the top 20 achieving >99% accuracy. Model training used a stratified train-test split with cross-validation. Blinded concordance analysis on 50 independent cases showed 94% agreement with expert clinical judgment, supporting the model's external decision-support capability under real-world constraints. Default hyperparameters were used to prioritize interpretability over optimization, and no synthetic oversampling was applied to maintain real-world class distribution.

Integrating AI-powered decision support, as demonstrated by this study, can significantly enhance strategic planning in healthcare enterprises managing uterine fibroids. By identifying high-risk patients earlier and with greater precision, health systems can optimize surgical scheduling, reduce pre-operative complications related to anemia (linked to ferritin), and improve resource allocation.

The ability of machine learning to capture complex interactions between metabolic markers like HbA1c, iron status, and hormonal profiles provides a more holistic view for personalized patient management. This leads to better patient outcomes, reduced readmission rates, and potentially lower long-term costs associated with chronic fibroid management. Such AI frameworks serve as critical tools for standardizing care pathways and supporting evidence-based, data-driven decisions at scale.

This study's retrospective design limits causal inference and control over unmeasured confounders like symptom severity or prior treatments. HbA1c measurements were not adjusted for anemia or iron supplementation, which can influence results. Model calibration was not assessed, and blinded concordance involved a single gynecologist.

Future research should employ prospective designs with standardized assessments of anemia, iron status, insulin resistance, and fibroid symptoms. Longitudinal evaluation of HbA1c dynamics pre/post-intervention is needed. Multi-center prospective validation with calibration analyses and multiple independent clinical raters will strengthen clinical applicability. These steps are crucial for developing generalizable, robust AI-based decision-support tools for fibroid management.

HbA1c: A Key Integrative Metabolic Marker

5.57 Mean HbA1c in Myomectomy Group (%)

Patients undergoing myomectomy had significantly higher HbA1c levels (5.57 ± 0.32%) compared to non-surgical patients (5.03 ± 0.61%, p < 0.001), indicating a strong association with surgical requirement in univariate analysis.

Key Predictive Factors for Myomectomy Requirement

Factor Univariate Analysis (OR, 95% CI) Multivariate Analysis (OR, 95% CI)
HbA1c 0.026 (0.012–0.055), p<0.001 (Strong) 0.24 (0.021–2.64), p=0.244 (Not significant)
Ferritin 2.87 (1.62–5.09), p<0.001 (Strong) 3.01 (1.52–5.95), p=0.002 (Strong)
FSH 1.08 (1.05–1.12), p<0.001 (Modest) 1.03 (0.88–1.20), p=0.696 (Not significant)
UF number 0.96 (0.89–1.04), p=0.390 (Not significant) N/A

While HbA1c showed a strong univariate association, its independent effect was confounded in multivariate models. Ferritin remained a robust, independent predictor, highlighting the complex interplay of metabolic and hematologic factors.

Clinical Application: AI-Driven Myomectomy Prediction

Scenario: A 38-year-old patient presents with symptomatic uterine fibroids. Traditional assessment considers fibroid size and symptoms. With AI integration, key metabolic (HbA1c, Ferritin) and hormonal (FSH) markers are analyzed alongside fibroid characteristics.

Outcome: The AI model, trained on 155 diverse algorithms, predicts a high probability of myomectomy requirement with 99% accuracy and 94% concordance with expert judgment. This informs a more confident and personalized recommendation for surgical intervention, potentially preventing prolonged conservative management that may delay fertility or worsen anemia.

Benefit: This approach exemplifies how AI can provide a holistic, data-driven perspective, integrating complex biological interactions to support earlier, more precise clinical decisions and optimize patient outcomes.
