Pulmonary Vein Varix Mimicking Prostate Cancer Metastasis on 68Ga–Prostate Specific Membrane Antigen-11 PET/CT

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, which confirmed the diagnostic of pulmonary vein varix.

In this study, we found that the mutation, copy number alteration, and methylation status of PRKAR2B gene have no correlation with its expression level in PCa. Then, we identified two microRNAs (miR-200b-3p and miR-200c-3p) to be critical regulators of PRKAR2B expression in PCa. Notably, miR-200b-3p and miR-200c-3p expression were significantly downregulated in metastatic CRPC and negatively correlated with the expression level of PRKAR2B in PCa tissues. Moreover, we characterized X-Box Binding Protein 1 (XBP1) as a key transcription factor responsible for PRKAR2B expression in PCa. Importantly, miR-200b-3p/200c-3p or XBP1...

Conclusions: Introducing pre-biopsy mpMRI into our contemporary PCa diagnosis pathway increased the diagnostic yield of transrectal biopsy by increasing the prostate cancer detection. This enabled the introduction of clinically significant prostate cancer (csPCa) treatment. mpMRI application also allowed biopsy to be avoided among patients with no csPCa. PMID: 31969912 [PubMed]

It is of interest because of a possible prognostic role of differential expression in tumors and its role as a target for indatuximab, a monoclonal antibody coupled with a cytotoxic agent. To comprehensively analyze ...

Increasing evidence has indicated that they mediate multiple physiological and pathological processes by regulating gene expression at the epigenetic, transcriptional, post-transcriptional, and translational levels. The deregulation of lncRNAs was ...

Introduction: Small cell prostate cancer (SCPC) is a rare histologic subtype of prostate cancer, for which the optimal staging strategy remains unclear. Method: The Surveillance, Epidemiology, and End Results database was used to analyze the incidence and outcomes of SCPC between the years 2004 through 2016. Limited-stage SCPC (LS-SCPC) was defined as SCPC without any metastasis regardless of local invasion. Extensive stage SCPC (ES-SCPC) was defined as any metastasis to lymph nodes and/or to distant organs. Result: A total of 403 SCPC patients were included in the study cohort, accounting for 0.056% of all prostat...

Purpose: The purpose of this study was to evaluate the treatment efficacy of stereotactic body radiotherapy (SBRT) in oligometastatic prostate cancer recurrence and to assess whether there is any relationship between biologically effective dose (BED) and local control (LC). Materials and Methods: Eligible studies were identified on Medline, Embase, and the Cochrane Library, and the proceedings of annual meetings through May 2019 were also identified. A meta-regression analysis was performed to assess whether there is a relationship between BED and LC. In the univariate analysis, studies were separated by the study des...

Authors: Jia Y, Gao Y, Dou J Abstract Effects of miR-129-3p on the biological functions of prostate cancer cells through the targeted regulation of Smad3 were investigated. RT-PCR was used to detect the expression levels of miR-129-3p in prostate cancer tissues and cells and its target gene Smad3 mRNA determined by bioinformatics prediction. Correlation between miR-129-3p and Smad3 was analyzed. MTT assay, cell invasion detection, and apoptosis detection were conducted to detect the effects of miR-129-3p and Smad3 on the proliferation, invasion, and apoptosis of prostate cancer cells. The results of RT-qPCR showed ...

ConclusionsOver the long term after RARP for PCA, the risk of hospital readmission is associated with ePLND. In patients who underwent RARP and ePLND, 4.4% of them had a readmission, compared to RARP alone, in which only 0.8% of cases had a readmission. When ePLND is planned for staging pelvic lymph nodes, patients should be informed of the increased risk of hospital readmission.
