A Treatment Decision Model for Cutaneous Squamous Cell Carcinoma Based on Bayesian Networks
Bayesian Networks (BNs) offer a robust framework for complex clinical decision-making, particularly in oncology. This analysis demonstrates how BNs can standardize treatment protocols, manage uncertainty, and integrate diverse patient data to provide transparent, individualized therapy recommendations for cutaneous squamous cell carcinoma (cSCC).
Executive Impact Summary
This study developed a Bayesian network-based decision support model to assist clinicians in selecting appropriate treatment strategies for patients with cutaneous squamous cell carcinoma (cSCC). The model achieved an impressive overall accuracy of 95.5% and statistical significance (p < 0.001) in retrospectively validating treatment recommendations against actual clinical decisions. It demonstrates the capability of BNs to integrate patient-specific clinical, histological, and genetic information, managing missing or uncertain data, to provide individualized treatment guidance. BNs offer inherent reproducibility and traceability, addressing the 'black-box syndrome' often associated with other machine learning approaches, thereby fostering trust in clinical decision support.

Cutaneous Squamous Cell Carcinoma (cSCC) & Treatment Challenges
cSCC is the second most common non-melanoma skin cancer, with rising global incidence. While typically treated surgically, advanced or inoperable cases present significant challenges, necessitating systemic therapies. Immune checkpoint inhibitors (ICIs) like Cemiplimab have revolutionized treatment for advanced cSCC, especially for patients unsuitable for conventional therapy. However, the complexity of factors—including TNM stage, histology, molecular features (e.g., PD-L1 expression), and patient-specific comorbidities—makes optimal treatment selection increasingly difficult for multidisciplinary tumor boards.
The growing number of therapeutic options and the intricate interplay of prognostic factors highlight the need for sophisticated decision support tools to ensure individualized and evidence-based treatment strategies. Our model directly addresses this complexity by integrating these diverse data points to offer clear, probabilistic recommendations.
Bayesian Networks (BNs) for Clinical Decision Support
Bayesian Networks (BNs) are powerful mathematical frameworks for representing probabilistic relationships among categorical variables in a directed acyclic graph. In a medical context, BNs can integrate clinical observations, diagnoses, and histological findings to create personalized patient models. A key advantage of BNs is their inherent comprehensibility, reproducibility, and traceability—critically important in clinical settings where "black-box" models are often distrusted.
Unlike many machine learning methods that demand vast, high-quality datasets, BNs can incorporate expert knowledge and guidelines, stabilizing inference even with smaller cohorts. This study leverages BNs to develop a clinical decision support tool for cSCC, demonstrating their potential to manage missing data, integrate multi-dimensional patient information, and provide transparent, individualized treatment recommendations that align with clinical guidelines and expert judgment.

Case Studies: Understanding Model Discrepancies
While highly accurate, the model's recommendations sometimes diverged from actual treatment due to unique patient characteristics not fully captured by the framework. These highlight the importance of clinical judgment alongside AI tools.
Patient A: Anatomical Constraint
Description: T2 N0 M0 cSCC. Model recommended surgery (90%), but tumor location (ocular angle/nasolacrimal duct) made surgical resection functionally infeasible. Actual: Cemiplimab.
Patient B: Comorbidities & Surgical Risk
Description: T2 N0 M0 cSCC. Model recommended surgery (90%), but severe comorbidities and high anesthesia risk prevented surgical treatment. Actual: Cemiplimab.
Patient C: Complex Co-morbidity & Recurrence
Description: pT3 N2 M0 cSCC with Chronic Lymphocytic Leukemia (CLL). Model favored Cemiplimab (80%) over surgery (70%). Adjuvant radiotherapy was recommended post-surgery but not administered due to poor general condition. Patient later developed locoregional recurrence and received Cemiplimab.
