This study investigated the protein expression profile of STC1 in PCa and benign prostatic hyperplasia (BPH) samples and STC1 signalling during cell proliferation and cell death in vitro using cell lines. We found higher levels of STC1 in PCa when compared to BPH tissue and that STC1 inhibited forskolin stimulation of cAMP in PC-3 cells. A monoclonal antibody against STC1 was effective in reducing cell proliferation, in promoting cell cycle arrest, and in increasing apoptosis in the same cells. Since STC1 acts as a regulator of prostatic tissue signalling, we suggest that this protein is a novel candidate biomarker for p...

Two cases with 68Ga-PSMA–avid prostate cancer recurrence in the vas deferens are presented. These cases highlight the clinical importance of imaging the pattern of local prostate cancer recurrence and the potential difficulties that arise due to the altered anatomy in the prostate bed after prostatectomy or radiotherapy.

We present a case of a 68-year-old man with disseminated peritoneal metastases and abdominal metastatic lymph nodes of PC, demonstrated in 68Ga-PSMA PET/CT with intense PSMA uptake.

We describe herein the early relapse detection of a hormone-sensitive metastatic upfront PCa treated with docetaxel on 68Ga-PSMA-11 PET/CT before biochemical progression. PSMA PET/CT should be considered to monitor PCa response to chemotherapy to detect early relapse, regardless of prostate-specific antigen levels, increasing the chances of finding low-volume oligoprogressive disease.

We present 3 cases with false-negatives for local (recurrent) prostate cancer on 68Ga-PSMA PET/CT, using multiparametric MRI and histopathology as reference standard. Metal artifact of prostate gold markers placed for external beam radiation therapy, low level of PSMA uptake, and bladder spillover are potential causes of misinterpretation. Awareness of these diagnostic pitfalls may improve 68Ga-PSMA PET/CT interpretation.

The use of PET/CT with prostate-specific membrane antigen radioligands for staging prostate cancer patients presenting a biochemical recurrence is increasing. As a consequence, the number of reports of diagnostic pitfall of this imaging modality is also increasing. A 75-year-old man referred for a second episode of biochemical recurrence of prostate cancer presented an isolated intense prostate-specific membrane antigen-11 uptake from a right lung abnormality. This abnormality was suggestive of pulmonary vein varix on contrast-enhanced lung CT. The uptake remained stable 1 month after starting androgen deprivation therapy,...

We describe herein a case of chronic nodular fasciitis of the left triceps muscle with a low 68Ga-labeled prostate-specific membrane antigen (PSMA) ligand uptake on PET/CT. 68Ga-PSMA ligands bind to PSMA-expressing prostate cancer cells, but uptake has also been demonstrated in other solid neoplasms and various benign lesions. Nodular fasciitis should be included in the differential diagnosis of soft tissue lesions with variable 68Ga-PSMA uptake.

68Ga-PSMA PET/CT has become a well-established imaging modality to detect prostate cancer (PCa) metastases in biochemical recurrence. Despite its claimed specificity for PCa, 68Ga-PSMA uptake in tissues unrelated to PCa, particularly in the neovascular tissue of other cancers, has been reported in numerous studies. A 73-year-old man underwent 68Ga-PSMA PET/CT for biochemical recurrence of PCa 7 years after radical prostatectomy. The 68Ga-PSMA PET/CT showed 1 lesion with PSMA uptake in the distal left ureter. Histology revealed a low-grade noninvasive papillary urothelial carcinoma. By immunohistochemistry, PSMA expression ...

We report here an mCRPC patient with lung, lymph nodes, and extensive bone metastases, who underwent 177Lu-PRLT and had excellent response to the treatment and complete regression of lung metastases after 177Lu-PRLT.
