The use of PET/CT scans in the assessment of resectability of colorectal liver metastases

Background: Surgical treatment of colorectal liver metastases (CLRM) depends on resectability that is currently based on the CT scan. With the PET/CT scan, a more accurate pre-operative assessment of resectability may be possible.

Methods: A Cochrane-based diagnostic test systematic review and a systematic review of cost-effectiveness studies on PET scans were conducted. Lastly, a diagnostic decision analysis model was created to assess the cost-effectiveness of the technology.

Results: PET/CT scans was equally sensitive for hepatic metastases and more sensitive for extra-hepatic metastases compared to CT scans. A cost-savings of PET scans for CRLM is identified; with decision modelling demonstrating a cost-savings with the addition of PET/CT scans to the current clinical algorithm.

Conclusion: There is cautious support for the addition of PET/CT scans to the pre-operative assessment in CRLM. Unnecessary surgery may be prevented, thus decreasing wait times. Future endeavours include finding, evaluating and validating methodology for appropriate effectiveness measures. / Health Technology Assessement
