The influence of AI on surgical and ablative treatments for colorectal liver metastases: a review of the current literature
This review assesses the current impact of AI techniques on local therapeutic strategies for Colorectal Liver Metastases (CRLM), highlighting promising results in prediction models for clinical outcomes and ablation zone segmentation. However, it notes challenges such as small sample sizes, lack of external validation, and robustness issues with traditional machine learning methods. The report emphasizes the need for large, multicentre studies, standardized workflows, and more explainable AI models to validate and implement AI-driven personalized treatment strategies effectively.

CRLM Treatment Overview
Colorectal cancer is a prevalent disease, with the liver being the most common site for metastases. Surgical resection remains the standard, but thermal ablation (RFA/MWA) has emerged as an effective minimally invasive alternative for lesions ≤ 3 cm, particularly in managing Local Tumour Progression (LTP).
AI in Thermal Ablation
AI, primarily machine learning (ML), is being used to predict Local Tumour Progression (LTP) and new CRLMs, and for ablation zone segmentation. Studies show high performance, but often involve small sample sizes and lack robustness.

AI in Surgical Resection
For surgical resection, AI and radiomics features predict recurrence, tumor growth patterns, mucinous type, and tumor budding. Models combining clinical and radiomics data generally outperform clinical-only models.

AUC-ROC for 3-year recurrence prediction post-surgery (with KRAS)
Context: Models incorporating clinical features, especially KRAS status, showed improved ability to predict recurrence risk post-hepatic resection. (Source: Paredes et al. (2020))
Predicting Post-Surgical Recurrence
Granata et al. investigated pre-surgical MRI-based radiomics with ML to predict outcomes like recurrence, tumor growth patterns, and tumor budding. Using techniques like SVM and KNN, models achieved 81-92% accuracy, demonstrating the potential of AI to enhance surgical planning and prognostic assessments. However, these were single-center studies with the same cohort, requiring broader validation.
Emphasis: AI-enhanced prognostic assessment.
Challenges & Future Directions
Current AI models face issues like small sample sizes, lack of external validation, and the 'black box' nature of deep learning. Future research needs large-scale multicentre studies, standardized data collection, and improved interpretability for AI tools to be clinically viable.
