About this study

This is an explorative diagnostic basic research study to assess the value of 18F-choline PET/CT and multi-sequence MRI for prostate cancer in patients undergoing diagnostic prostate biopsy. Patients will receive image-guided (targeted) prostate biopsies and metabolomic profiling of prostate biopsy tissues to evaluate underlying metabolic changes in comparison with pathological Gleason grading.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Males 40 years of age or older scheduled for prostate biopsy (for known or suspected prostate cancer) followed by planned prostatectomy (population group A)
  • Males 40 years of age or older with known (biopsy-confirmed) primary adenocarcinoma of the prostate undergoing active surveillance scheduled for prostate biopsy (population group B)

Exclusion criteria

  • Androgen ablation (hormone treatment) within the last 3 months
  • Prostate biopsy within 6 weeks prior to PET or MRI imaging
  • Active inflammatory bowel disease within the last 6 months
  • Acute prostatitis within the last 6 months
  • A non-urologic bacterial infection requiring active treatment with antibiotics
  • Active other malignancy (except basal cell or squamous cell skin cancer) within the last 2 years
  • Previous radiation treatment of the pelvis
  • Symptomatic distal rectal stenosis
  • Known hypersensitivity to glucagon
  • Pheochromocytoma, insulinoma or galactosemia
  • Insulin-dependent diabetes

Treatment and study plan

Prostate Cancer Imaging

Procedure

After imaging is completed, subjects will be scheduled for a prostate biopsy performed as part of their clinical care. If the imaging has identified suspicious lesions in the prostate, these regions will be made visible for the Urologist to be targeted for additional biopsies. These additional biopsies will undergo histological evaluation and further metabolomic testing to better understand metabolic differences between various grades of prostate cancer lesions.

Primary outcomes

  1. Evaluation whether the odds of primary Gleason ≥ 3+4 are greater for image-guided biopsy (based on parametric PET/MRI) than for non-image-guided (standard) biopsy.

    Time frame: 4 years
