Ga68-labeled Fibroblast Activation Protein Inhibitor-46 (Ga68-FAPI-46) PET/CT for Preoperative Assessment of Peritoneal Carcinomatosis
This is a prospective, phase II, non-randomized clinical imaging trial. Ga68-FAPI-46 is a novel radiotracer used in PET/CT imaging, targeting a protein of the tumor microenvironment called FAP (Fibroblast activation protein). The aim of the study is to assess the accuracy of Ga68-FAPI-46 PET/CT for preoperative assessment of peritoneal carcinomatosis in colorectal and ovarian cancer.
• Histologically proven colorectal and ovarian cancer.
• Known or suspected peritoneal metastases from the tumour of origin.
• Scheduled for peritoneal complete cytoreductive surgery with curative intent with or without neoadjuvant chemotherapy.
• ECOG (Eastern Cooperative Oncology Group) Performance status ≤2.
• Signed written informed consent obtained before any study-specific screening procedures.
