Using Ga68-FAPI-46 PET/CT to assess peritoneal carcinomatosis before surgery

Ga68-labeled Fibroblast Activation Protein Inhibitor-46 (Ga68-FAPI-46) PET/CT for Preoperative Assessment of Peritoneal Carcinomatosis

Not applicable Interventional Jules Bordet Institute · NCT06061874

This study is testing a new type of imaging scan to see if it can better detect cancer spread in the abdomen before surgery for people with colorectal and ovarian cancer.

What this trial studies

This clinical imaging trial evaluates the effectiveness of Ga68-FAPI-46 PET/CT in accurately assessing peritoneal carcinomatosis in patients with colorectal and ovarian cancer. The study aims to correlate the imaging findings with intraoperative histopathology results to determine the accuracy of this novel radiotracer. Ga68-FAPI-46 targets fibroblast activation protein in the tumor microenvironment, potentially offering improved sensitivity over traditional imaging methods. Participants will undergo PET/CT scans prior to scheduled cytoreductive surgery.

Who should consider this trial

Good fit: Ideal candidates include individuals with histologically confirmed colorectal or ovarian cancer and known or suspected peritoneal metastases scheduled for curative surgery.

Not a fit: Patients with non-resectable extra-abdominal metastases or significant chronic inflammatory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate preoperative assessments, improving surgical outcomes for patients with peritoneal carcinomatosis.

How similar studies have performed: While the use of Ga68-FAPI PET/CT is a novel approach, similar imaging techniques targeting tumor microenvironments have shown promise in other studies.
