Brief Summary

The goal of this clinical trial is to learn if \[68Ga\]Ga-FAPI-46 Total Body PET/CT can diagnose patients suffering from gastroesophageal cancer and pancreatic cancer. The investigators hope that \[68Ga\]Ga-FAPI-46 Total Body PET/CT can improve staging and treatment evaluation for these patient groups. The main questions the trial aims to answer are:

  • Is \[68Ga\]Ga-FAPI-46 Total Body PET/CT better at diagnosing metastatic disease in the abdomen compared other imaging modalities?
  • Can \[68Ga\]Ga-FAPI-46 Total Body PET/CT produce accurate images in less than 30 min? Researchers will examine three different patient groups: Group A) patients with pancreatic cancer, who are referred to surgery. Group B1) patients with gastroesophageal cancer, who are referred to diagnostic surgery (laparoscopy). Group B2) a subgroup of gastroesophageal cancer patients, with a specific subtype cancer (signet ring cell carcinoma or poorly cohesive carcinoma), who are referred to oncological treatment. Participants will undergo:
  • One \[68Ga\]Ga-FAPI Total Body PET/CT before surgery (Group A), or before laparoscopy (group B1), or before oncological treatment (Group B2).
  • Participants in group B2 will also undergo a second \[68Ga\]Ga-FAPI-46 Total Body PET/CT during treatment with chemotherapy.
  • All participants will fill out one questionnaire.
  • Researchers will follow the patients after the scans for 1 year.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity of [68Ga]Ga-FAPI-46 Total Body PET/CT

    Sensitivity of lesions suspicious of malignancy of \[68Ga\]Ga-FAPI-46 Total Body PET/CT within 30 min of injection of the tracer compared with the sensitivity of current standard imaging modalities (\[18F\]FDG PET/CT, CT, MRI). Sensitivity will be measured as the proportion of true positive malignant findings on \[68Ga\]Ga-FAPI-46 Total Body PET/CT within 30 mins of injection of the tracer. This will be done, by comparing the lesions suspicious of malignancy found on \[68Ga\]Ga-FAPI-46 PET/CT, and standard imaging with the results from the curative surgery and/or a composed reference standard, which consist of all available imaging, 6 months follow up and blinded expert opinion.

    From the time of scan to the end of follow up at 1 year

Secondary Outcomes (3)

  • Accuracy measurements of [68Ga]Ga-FAPI-46 Total Body PET/CT

    From the time of scan to the end of follow up at 1 year

  • Estimated potential impact/change in patient management.

    From the time of scan to the end of follow up at 1 year

  • Description of FAPI-uptake from lesions suspicious of malignancy.

    From the time of scan to the end of follow up at 1 year

Other Outcomes (2)

  • Patients' experience of a [68Ga]Ga-FAPI-46 Total Body PET/CT compared to standard imaging modalities.

    Immediately after completion of the scan (single time point)

  • Uptake of [68Ga]Ga-FAPI-46 from lesions suspicious of malignancy wil be correlated with progression free survival (PFS)

    From the time of scan to the end of follow up at 1 year
