NCT06395337

Brief Summary

Most digestive cancers show (over)expression of the tumour marker carcinoembryonic antigen (CEA). Therefore, interest in CEA-targeting tracers has increased over the past years. CEA-targeting tracers can be used for preoperative, intra-operative and postoperative imaging purposes. This study focusses on both preoperative and intraoperative multimodal imaging and image-guided surgery in patients with rectal cancer or pancreatic cancer.

Study Arms (1)

Intraoperative multi-modality imaging

EXPERIMENTAL

Patients receive a single intravenous dose of \[111In\]In-DOTA-ANTI-CEA antibody. At day 4 or 5 after antibody injection a SPECT/CT scan will be acquired. At day 6 or 7 standard of care cytoreductive surgery will be performed. This will be extended with the use of dual-modality imaging.

Drug: [111In]In-DOTA-ANTI-CEA antibody injectionRadiation: SPECT/CT scanProcedure: Resection surgery
