Renal cell carcinoma (RCC) is common with more than 60,000 new cases in the United States yearly. No curative therapies are available for metastatic RCC. Improved methods of imaging metastatic RCC would be of value in identifying sites of occult disease and potentially for judging response to therapy. A 58-year-old man with known metastatic clear cell RCC was imaged with both 18F-FDG and 18F-DCFPyL PET/CT. 18F-DCFPyL is a small molecule inhibitor of the prostate-specific membrane antigen (PSMA), a target known to be highly expressed on solid tumor neovasculature. Relative to 18F-FDG, 18F-DCFPyL identified more lesions and demonstrated higher tumor radiotracer uptake.

Positron emission tomography/computed tomography (PET/CT) using prostate-specific membrane antigen (PSMA)-radioligands is currently suggested by several clinical guidelines for the assessment of prostate cancer (PCa) in various clinical settings. However, PSMA will also be overexpressed in different cancers, which should be considered on the PSMA PET/CT reading in patients with concomitant neoplastic diseases. We report a case of 82-year-old male presented with prostate and history of oesophageal cancer and B-cell chronic lymphocytic leukemia (B-CLL).

In most cases, prostate cancer spreads locally to the seminal vesicles, via lymphatics to pelvic and abdominal lymph nodes, and hematogenously to the bones. Direct invasion along nerve roots is exceptionally rare but can occur. Here, we present a case with 18F-DCFPyL PET/CT images showing neoplastic involvement of the lumbosacral plexus in a patient with recurrent prostate cancer.

Purpose: There are limited data on prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/CT for workup of recurrence after radical prostatectomy (RP) at low PSA values. We evaluated a PSMA PET/CT cohort of patients post RP, focusing on patients with PSA < 0.5 ng/mL.

Purpose: To evaluate the diagnostic performance of PSMA PET/CT, including [Ga]Ga-PSMA-11 and [F]DCFPyL, in comparison with the [Tc]Tc-MDP bone scan (BS) in identifying bone metastases among prostate cancer patients.
Methods: A search was performed in the PubMed and Embase databases to locate pertinent publications from inception to February 12, 2024. The studies included were those that examined the diagnostic effectiveness of PSMA PET/CT (covering [Ga]Ga-PSMA-11 and [F]DCFPyL) compared to [Tc]Tc-MDP BS in identifying bone metastases among prostate cancer patients.

In Canada and across the globe, access to PSMA PET/CT is limited and expensive. For patients with biochemical recurrence (BCR) after treatment for prostate cancer, novel strategies are needed to better stratify patients who may or may not benefit from a PSMA PET scan. The role of the free-to-total prostate-specific antigen (PSA) ratio (FPSAR) in posttreatment prostate cancer, specifically in the PSMA PET/CT era, remains unknown.
