PURPOSE Prostate-specific membrane antigen (PSMA), which is a transmembrane glycoprotein predominantly expressed in prostate cancer, is an attractive target for tumor-specific immunotherapy. To identify human leukocyte antigen (HLA)-A24-restricted epitope peptides from PSMA for further application of the dendritic cell (DC)-based immunotherapy targeting prostate cancer, we have screened several...
Prostate cancer (CaP) is the most common noncutaneous malignancy affecting men in North America. Despite significant efforts, conventional imaging of CaP does not contribute to patient management as much as imaging performed for other common cancers. Given the lack of specificity in conventional imaging techniques, one possible solution is to screen for CaP-specific antigenic targets and genera...
BACKGROUND To prove the feasibility of integrating CT urography (CTU) into 68Ga-PSMA-11 PET/CT and to analyze the impact of CTU on assigning focal tracer accumulation in the ureteric space to either ureteric excretion or metastatic disease concerning topographic attribution and diagnostic confidence. METHODS Ten prostate cancer patients who underwent 68Ga-PSMA-11 PET/CT including CTU because ...
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with continuously ...
OBJECTIVES: To evaluate the correlation between intensity of prostate specific membrane antigen (PSMA) expression by Gallium-68-PSMA positron emission tomography/computer tomography (Ga-68-PSMA PET/ CT) and D’Amico risk classification newly diagnosed cancer patients. MATERIALS AND METHODS: Retrospective reviews 61 patients, who underwent Ga-68-PSMA PET/CT September 2017 November 2021. Data maxi...
The purpose of this study was to evaluate the accuracy of Glu-NH-CO-NH-Lys-(Ahx)-[68Ga(HBED-CC)] PET compared with morphologic imaging for the assessment of lymph node metastases (LNM) in patients with recurrent prostate cancer. METHODS Forty-eight patients (median age, 71 y; interquartile range, 66-74 y) with biochemical recurrence (median prostate-specific antigen level, 1.31 ng/mL; interqu...
The interleukin-6 (IL-6) and the chemokine CCL5 are implicated in the development and progression of several forms of tumours including that of the prostate. The expression of the prostate specific membrane antigen (PSMA) is augmented in high-grade and metastatic tumors. Observations of the clinical behaviour of prostate tumors suggest that the increased secretion of IL-6 and CCL5 and the highe...
We have identified two synthetic oligonucleotides (aptamers) that bind to prostate cancer cells,with low nanomolar affinity, via the extracellular portion of the prostate-specificmembrane antigen (PSMA). These two specific aptamers were selected from an initial 40mer library of approximately 6 x 10(14) random-sequence RNA molecules for their ability to bind to a recombinant protein representing...
PURPOSE The discovery of new diagnostic tools for the diagnosis of prostate cancer (PCa) has become an important field of research. In this study, we analyzed the diagnostic value of the expression of the pepsinogen C (PGC) and prostate-specific membrane antigen (PSMA) genes in tissue samples obtained from prostate biopsies. MATERIALS AND METHODS This study was comprised of 51 consecutive pat...
Background and purpose: We investigated the role of Ga-PSMA-PET (PSMA) to determine the location of disease recurrence in those with a rising PSA following definitive external beam radiation treatment (EBRT). Materials and methods: 538 men were treated with image guided EBRT to a dose of 78 or 82 Gy between 2007 and 2014. Patients at least 24 months post EBRT with biochemical failure (nadir + 2...
