Survival in patients diagnosed with castration-resistant prostate cancer: a population-based observational study in Sweden.

Conclusions: M1 disease at PC diagnosis was associated with worse survival after CRPC onset versus M0. Higher Gleason score at diagnosis was associated with higher mortality after CRPC onset in M0 patients at diagnosis. PMID: 32266854 [PubMed - as supplied by publisher]

Rationale: Prostate-specific membrane antigen positron emission tomography-computed tomography (18F-PSMA-1007 PET/CT) imaging is an emerging method for the diagnosis of prostate cancer (PC), but its efficiency in detecting other accompanying diseases has rarely been investigated. Patient concerns: A 77-year-old man presented with a complaint of bone pain throughout his entire body lasting for 2 weeks. Routine preoperative whole-body bone scanning revealed multiple osteogenic metastases. His alpha-fetoprotein and prostate-specific antigen levels were 108.2 ng/mL and 53.32 ng/mL, respectively. 18F-PSMA-1007 PET/...

In this study, we show that18F-DCFPyl might detect neovasculature in advanced, metastatic differentiated thyroid cancer (DTC). We first stained the preserved lymph node samples of three patients with DTC who had undergone total thyroidectomy and neck dissection for cervical lymph node metastatic disease to identify PSMA expression, with the PSMA antibody (DAKO Monoclonal). Then, we performed18F-DCFPyl imaging in two other advanced DTC patients with elevated serum thyroglobulin (Tg), indicative of residual disease. We compared the findings with contemporaneous FDG PET/CT scan, conventional Imaging (CT,MRI) and whole-body sc...

A 66-year-old man was diagnosed with metastatic prostate cancer to the bones. The patient started 223Ra-dichloride (Xofigo) therapy in April 2019. 99mTc-MDP bone scan and 18F-fluciclovine (Axumin) PET/CT showed discordant but overall complementary findings that indicated disease progression after 5 doses of Xofigo therapy. The patient’s prostate-specific antigen increased from 33.81 ng/mL at baseline before Xofigo therapy and up to 394.3 ng/mL after the fifth dose of Xofigo treatment. Because of disease progression, Xofigo therapy was discontinued.

ConclusionsThreshold-based contouring using GTVmajority-trained SOSTs achieves an accuracy comparable with manual contours in delineating GTVhisto. The median SOSTs of 41 SUV% for68Ga-PSMA-11 PET and 44 SUV% for18F-PSMA-1007 PET form a base for tracer-specific window levelling.Trial; NCT03327675; 31-10-2017

Abstract Biochemically recurrent prostate cancer represents a stage of prostate cancer where conventional (continued on next page) computed tomography and technetium Tc 99m bone scan imaging are unable to detect disease after curative intervention despite rising prostate-specific antigen. There is no clear standard of care and no systemic therapy has been shown to improve survival. Immunotherapy-based treatments potentially are attractive options relative to androgen deprivation therapy due to the generally more favorable side-effect profile. Biochemically recurrent prostate cancer patients have a low tumor burden...

Conclusions: After loading into the above nanocomposite, the free CaO2 without a significant antitumor effect can exert excellent antitumor efficacy by responsively releasing ROS under the acidic TME to induce the mitochondria-mediated apoptosis via remarkable oxidative stress and simultaneously minimize damages to normal tissues. The current study presents a new concept of “efficacy-shaping nanomedicine” for the tumor-selective treatment of prostate cancer.

CONCLUSION: We provide Unity system specific recommendations for measuring the ADC. This will increase the consistency of ADC values acquired in different centers on the Unity system, enabling large cohort studies for biomarker discovery and treatment response monitoring.

Abstract The PI-RADS guidelines set out the minimal technical requirements for the acquisition of multiparametric magnetic resonance imaging (mpMRI) of the prostate. However, the rapid diffusion of this technique has inevitably led to variability in scan quality among centres across the UK and the world. Suboptimal image acquisitionreduces the sensitivity and specificity of this technique for the detection of clinically significant prostate cancer and result in clinicians losing confidence in the technique.Two expert panels (one from the UK and one from the ESUR/ESUI) have stressed the importance to establish qual...
