Prostate Cancer Screening Trial Using Imaging
Prostate NeoplasmParticipants will be recruited from the community and attend a screening clinic and undergo the following screening tests: Bi-parametric MRI - reported by a radiologist and CAD-AI system Multiparametric ultrasound - including shearwave elastography A standard-of-care PSA test A systematic +/- targeted biopsy will be performed if any tests are positive, independent of the other tests.
4Kscore Using Serum Stored Uncentrifuged
Prostate CancerThe purpose of the study is to evaluate whether storage of serum uncentrifuged is an allowable preanalytical procedure
Early and Accurate Detection of Prostate Cancer in General Practice
Prostate CancerProstate Neoplasm1 moreProstate cancer (PC) is the most common malignancy (4500 new cases/year) and the second leading cause of cancer-associated mortality (1200 deaths/year) among men in Denmark. PC is generally diagnosed on the basis of an elevated prostate specific antigen blood test followed by transrectal ultrasound (TRUS)-guided prostate biopsy. This study aims to test early detection of PC in general practice, using the STHLM3 model with superior specificity and sensitivity for clinically significant PC, combined with multiparametric magnetic resonance imaging (mpMRI) of the prostate and MR guided biopsy.
68Ga PSMA in Preprostatectomy Patients
Prostate CancerProstatic Neoplasm3 moreThis study investigates if a new drug (PSMA) makes prostate cancer easier to identify in positron-emission tomography (PET) imaging. If this works, prostate cancer treatments can be prescribed that match the location of the disease. PSMA is radiolabeled with Gallium-68 (Ga-68). This means a participant receives a small dose of radiation from the drug - less than the annual radiation limit for a medical worker. To test this new drug, participants will receive an injection of Ga-68 PSMA and then have a PET scan. This PET scan, and the reported results, will be entered into the medical record and shared with the treating oncologists.
The Effects of Radium-223 Dichloride Therapy on Radionuclide Bone Scan Lesions.
Bony Metastases From Castrate Refractory Prostate CancerTo describe the changes seen on bone scan and correlate them with changes in relative chemical biomarkers, patient's functional status and level of pain.
PET/MRI for the Staging of Newly Diagnosed Prostate Cancer
Prostate CancerThe purpose of this study is to gain understanding of how PET-MR (positron emission tomography-magnetic resonance imaging) using the substance 18F-DCFPyL (PyL) may help in diagnosing prostate cancer and in determining the stage of prostate cancer before surgery.
MR Radiomic Features in Prostate Cancer
Prostate CancerA combination of correct interpretation of imaging and biopsy has given promising results in terms of detecting clinically significant cancer at radical prostatectomy.
Immune Profiling After HDR in Local Relapsed Prostate Cancer
Prostate CancerPD-L1Immunotherapy is currently revolutionizing the field in oncology. However, prostate cancer until now fails to respond to classical IO, like PD-1 and CTLA-4 inhibitors. Radiotherapy (RT) delivered to the primary tumor impacts both tumor cells and surrounding stromal cells. Radiation damage to cancer cells exposes tumor-specific antigens leading to increased visibility to the immune system by improved priming and activation of cytotoxic T cells. RT-induced modulation of the tumor microenvironment may also facilitate the recruitment and infiltration of immune cells by increasing the expression or T-cell attracting chemokines and by increasing T-cell docking molecules on the endothelial cells like VCAM-1. The main-hypothesis is that HDR-brachytherapy will turn an immunologically "cold" (no T-cell infiltrations) prostate cancer into an immunologically "hot" (CD4 and CD8-cell infiltrations) tumor, creating leverage points for different forms of IO.
The Biopsychosocial Burden of Prostate Biopsy
Prostate CancerProstate biopsy was offered to 47 consecutive patients with prostate-specific antigen (PSA) over 4 ng/dl or suspicious digital rectal examination (DRE) of whom 16 had undergone a biopsy. Comprehensive validated questionnaires at TIME 0 (pre-biopsy), TIME 1 (before diagnosis, 20 days after biopsy) and TIME 2 (after diagnosis, 40 days after biopsy) accessed patients' erectile (IIEF-5) and voiding (IPSS) functions, Beck scales measured anxiety (BAI), hopelessness (BHS) and depression (BDI), added to the emotional thermometers including five visual analog scales for distress, anxiety, depression, anger and need for help. Mann-Whitney or Friedman tests were obtained among times and studied variables.
Effect of TyG Index on Outcomes of Radical Prostatectomy
Metabolic SyndromeProstate Cancer1 moreWe investigate the association between Triglyserid-Glucose(TyG) index and prostate cancer in patients undergoing radical prostatectomy.
