ENTERPRISE AI ANALYSIS
The relationship between CTCs, TFD and postoperative prognosis of cervical cancer patients and the construction of prediction models
This study develops and validates a novel risk prediction model for cervical cancer recurrence/metastasis, integrating circulating tumor cells (CTCs) and tumor fibrosis distance (TFD). Unlike conventional models, this approach offers superior preoperative discrimination for recurrence risk, guiding personalized treatment and improving patient outcomes through early risk stratification and biological mechanism validation in animal models.

Precision Biomarker Identification
This section delves into the critical role of Circulating Tumor Cells (CTCs) and Tumor Fibrosis Distance (TFD) as key preoperative indicators for cervical cancer prognosis. We examine their definitions, methods of measurement, and their individual correlations with crucial clinical features such as tumor diameter, advanced FIGO stages, and lymph node metastasis. Understanding these biomarkers is foundational to building a robust predictive model.

Advanced Prognostic Model Development
Here, we detail the construction of a logistic regression model that integrates CTC counts and TFD values to predict postoperative recurrence/metastasis. This section highlights how independent risk factors were identified, how a risk scoring system was developed based on their effect sizes, and the superior performance of the combined model compared to individual markers in terms of AUC, sensitivity, specificity, and negative predictive value.

Stratified Clinical Management
This section outlines the practical application of our predictive model in stratifying cervical cancer patients into low-, intermediate-, and high-risk groups based on their total risk scores. For each stratum, we provide clear, evidence-based recommendations for personalized postoperative surveillance and adjuvant treatment strategies, ensuring optimal patient outcomes while minimizing unnecessary interventions.
Risk Group Recommendations:
- Low-risk group (<10% recurrence/metastasis): Routine follow-up every 6 months was recommended, considering the indolent disease course and cost-effectiveness.
- Intermediate-risk group (10%-30%): Intensified surveillance every 3 months, including imaging evaluations, was advised to detect early signs of progression.
- High-risk group (>30%): Prophylactic chemoradiotherapy and monthly multidisciplinary team (MDT) assessments were initiated. This approach integrates emerging evidence on tumor heterogeneity to reduce metastatic burden through proactive intervention.
Mechanistic Validation in Animal Models
To biologically validate the clinical model, an orthotopic rat cervical cancer model was established. This section presents key findings from the animal experiments, demonstrating how high-risk groups (high CTC load + low TFD) exhibited elevated tumor burden, immunosuppression (reduced CD4+/CD8+ ratios), systemic inflammation (increased IL-6, TNF-a), and significant oxidative damage. These results provide mechanistic support for the clinical observations.
Animal Model Confirms High-Risk Pathways
In the high CTC + low TFD group of rats, significant metabolic impairment and high tumor burdens were observed, mirroring poor patient outcomes. This group also showed marked immunosuppression (reduced CD4+/CD8+ ratios) and a strong systemic inflammatory response (increased IL-6 and TNF-a levels). Furthermore, significant oxidative damage (reduced SOD, elevated MDA) supported the role of oxidative stress in tumor progression. These findings provide robust biological plausibility for the clinical prediction model.
