Objective:

To compare local tumour progression (LTP) rates after ultrasound (US)-guided thermal ablation with or without intraprocedural CT control for colorectal liver metastases (CRLM), focusing on the primary outcome of LTP rates.

Key Findings:
  • LTP rates were assessed to determine the effectiveness of CT guidance compared to US alone, with specific rates to be included.
  • The study evaluated whether tumour size modified the effect of CT control, with statistical analysis results to be detailed.
  • Management of LTP was reported to assess clinical consequences, including treatment outcomes.
Interpretation:

The study aims to clarify the added value of CT control in optimizing resource allocation for CRLM treatment, potentially influencing clinical guidelines.

Limitations:
  • Non-randomized allocation of cases to CT or OR groups may introduce selection bias.
  • Limited CT availability may have influenced treatment assignment, affecting generalizability.
Conclusion:

The findings will contribute to understanding the effectiveness of imaging modalities in thermal ablation for CRLM, highlighting the potential benefits of CT guidance.
