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.

Are prostate cancer biopsies reliably accurate? Not always. The most common method, called a systematic biopsy, sometimes misses tumors, and it can also misclassify cancer as being either more or less aggressive than it really is. During systematic biopsy, a doctor takes 12 evenly-spaced samples of the prostate, called cores, while looking at the gland with an ultrasound machine. A new method, called MRI-targeted biopsy, guides doctors to suspicious abnormalities in the prostate, and emerging evidence suggests that it’s better at detecting high-grade, aggressive tumors that need immediate treatment. These biopsies re...

Whole-pelvis pencil beam scanning (PBS) proton therapy is utilized in both the intact and post-operative settings in patients with prostate cancer. As whole pelvis prostate radiotherapy has traditionally been delivered with standard photon beams, limited evidence and technical descriptions have been reported regarding the use of proton therapy. Here we present two robust three-field treatment planning approaches utilized to maximize target coverage in the presence of anatomic and delivery uncertainties.

ConclusionsAn incidence of 0.1% in our study confirms the rarity of penile metastases of prostate cancer. Although rare, identification of prostate cancer penile metastases is important for appropriate treatment management and symptom ‐relief.

ung P Abstract PURPOSE: To report dosimetry, preliminary toxicity and health-related quality of life (HRQoL) outcomes of tumor-targeted dose-escalation delivered by integrated boost volumetric arc therapy (IB-VMAT) or MR-guided HDR brachytherapy (HDR) boost for prostate cancer. MATERIALS AND METHODS: Patients diagnosed with localized prostate cancer, with at least 1 identifiable intraprostatic lesion on multiparametric MRI (mpMRI) were enrolled in a prospective non-randomized phase II study. All patients received VMAT to the prostate alone (76 Gy in 38 fractions) plus a GTV boost: IB-VMAT (95Gy in 38 fraction...
