Diffusion-Weighted MRI for Liver Metastasis
- Conditions
- Malignant Neoplasm of Rectum Metastatic to LiverColorectal CancerColon Cancer Liver Metastasis
- Registration Number
- NCT02781935
- Brief Summary
The DREAM study will assess the diagnostic accuracy of diffusion-weighted MRI in combination with other imaging modalities (multiparametric MRI and CT Scan) in determining the true status of disappearing liver metastasis (DLM) detected after conversion systemic therapy for unresectable or borderline resectable colorectal liver metastasis (CRLM).
- Detailed Description
The advancements of systemic and local therapies for complex CRLM have led to the increased incidence of DLMs. It is hypothesized that DW-MRI imaging could distinguish between a metastasis not completely sterilized by conversion therapy and a sterilized scar (non-viable tumor). If this can be demonstrated, the use of DW-MRI could make a significant impact on the surgical decision making process by providing surgeons a more reliable guide to decide whether to leave behind or to resect/ablate a site of DLM. Most importantly, this surgical choice can also have a significant impact on patient outcomes as it may impact the risk of local recurrence and the need for re-operation.The possibility of improving surgical management of complex CRLM is foreseen if the benefit of observing or resecting small residual metastases and DLMs is clarified through a multi-center and international prospective study.
