Study Overview

Multimodal Imaging in Rectal Cancer & Pancreatic Cancer

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.

Masking:
None


Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: Intraoperative multi-modality imaging

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

DRUG: [111In]In-DOTA-ANTI-CEA antibody injection

  • tracer injection

RADIATION: SPECT/CT scan

  • abdominal and thoracic SPECT/CT scan

PROCEDURE: Resection surgery

  • oncological resection surgery will be performed extended with the use of dual-modality imaging.
Primary Outcome MeasuresMeasure DescriptionTime Frame
Safety of dual-labeled antibody as assessed by the number of participants with grade 3 or 4 Adverse Events according to CTCAE v4.0Safety of dual-labeled antibody injection as assessed by the number of participants with grade 3 or 4 Adverse Events according to CTCAE v4.030 days
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Intensity of fluorescenceTo assess the intensity of fluorescence in malignant and non-malignant tissue, using quantifiable images7 days
Intensity of radiosignalTo assess the intensity of the radiosignal in malignant and non-malignant tissue, using radioactive measuring device.7 days
Concordance between CEA and tracerTo assess the concordance between localization of the [111In]In-ANTI-CEA and CEA expression in rectal or pancreatic cancer and non-malignant tissue, by analyzing pathologic tissue for tracer activity and CEA presentation7 days
Blood levels of the dual-labeled antibodyTo determine blood concentrations at several time points in patients to assess the pharmacokinetics of the tracer.30, 60, 120, 180 minutes
BiodistributionTo determine the whole body biodistribution of the tracer over time by quantified SPECT/CT imaging at 2 timepoints.7 days
