Prostate-Specific Membrane Antigen PET/CT Suitable Imaging for Prostate Cancer

Prostate-specific membrane antigen PET/CT was found to be a suitable replacement for conventional imaging in patients with prostate cancer, providing superior accuracy to the combined findings of CT and bone scanning.

This study investigated the performance of 68Ga-prostate-specific-membrane-antigen-11 positron-emission-tomography/computed-tomography for detecting prostate carcinoma in patients with rising prostate-specific-antigen after primary therapy. Six hundred sixty (660) patients with biochemical recurrence referred for positron-emission-tomography/computed-tomography with 68Ga-prostate-specific-membrane-antigen-11 were evaluated retrospectively. Prostate-specific-antigen-stratified cohorts of pathological scan results were analyzed, and relationships between prostate-specific-antigen kinetics and PSMA-positive tumor lesions were...

Our purpose was to evaluate the performance of 11C-choline PET/CT in detecting biochemically recurrent prostate cancer (PCa) in a large non-European cohort (in the context of emerging evidence for prostate-specific membrane antigen PET in this setting) and to map patterns of PCa recurrence. Methods: We retrospectively analyzed 11C-choline PET/CT scans from 287 patients who were enrolled in an imaging protocol based on rising prostate-specific antigen (PSA) levels (mean, 3.43 ng/mL; median, 0.94 ng/mL; range, 0.15–89.91 ng/mL) and suspected recurrent PCa. A total of 187 patients had undergone primary radical prostatec...

Our objective was to investigate the lesion detection rate of 18F-DCFPyL PET/CT, a prostate-specific membrane antigen (PSMA)–targeted PET agent, in patients with biochemically relapsed prostate cancer after primary local therapy. Methods: This was a prospective institutional review board–approved study of 90 patients with documented biochemical recurrence (median prostate-specific antigen [PSA], 2.5 ng/mL; range, 0.21–35.5 ng/mL) and negative results on conventional imaging after primary local therapies, including radical prostatectomy (n = 38), radiation (n = 27), or a combination of the two (n = 25). Pa...

eriaudeau In this paper, we present an evaluation of four encoder–decoder CNNs in the segmentation of the prostate gland in T2W magnetic resonance imaging (MRI) image. The four selected CNNs are FCN, SegNet, U-Net, and DeepLabV3+, which was originally proposed for the segmentation of road scene, biomedical, and natural images. Segmentation of prostate in T2W MRI images is an important step in the automatic diagnosis of prostate cancer to enable better lesion detection and staging of prostate cancer. Therefore, many research efforts have been conducted to improve the segmentation of the prostate gland in MRI i...

ConclusionsWe have successfully synthesized the radiotracer [18F]2 ‐amino‐4‐((2‐((3‐fluorobenzyl)oxy)benzyl)(2‐((3‐(fluoromethyl)benzyl)oxy)benzyl)amino)butanoic acid.In vitro experiments show a good affinity for both the human and rat ASCT ‐2. However, the tracer suffers from poorin vivo tumor uptake in the PC ‐3 model. Briefly, we present the first fluorine‐18 labelled derivative of compound V‐9302, a promising novel ASCT‐2 blocker used for inhibition of tumor growth.

ConclusionsIntegrated [68Ga]PSMA-11 PET/MRI provides a similarly high diagnostic performance for localization of recurrent PC as PET/CT. For the detection of local recurrences [68Ga]PSMA-11 PET/MRI is superior compared with [68Ga]PSMA-11 PET/CT.

Conclusion: Our patient, diagnosed with recurrent prostate BCC after receiving a radical prostatectomy, responded to treatment with etoposide. Radical prostatectomy and radiotherapy should remain first-line therapy; however, etoposide may be an alternative second-line therapy when other options are not available. Consensus regarding treatment plans, and the molecular mechanisms behind prostate BBC, must be elucidated.
