In recent years, PSMA-targeting PET tracers such as Ga-PSMA-11 have shown promising results, thus contributing to a better management of prostate cancer patients. At the present time, Ga-PSMA-11 is most frequently used for diagnostic evaluation in the setting of biochemical recurrence of prostate cancer. In this context, the Ga-PSMA-11 PET/CT delivers superior detection rates compared to conventional imaging, especially for the detection of small, unsuspicious lesions or lesions in the presence of low PSA values. Furthermore, Ga-PSMA PET imaging seems to be an encouraging alternative for the staging of high-risk patients, particularly in combination with multiparametric MRI. In addition to the increasing use of PSMA ligands in clinical diagnostics, some variants have also been successfully applied in therapy. Advanced metastasized prostate cancer patients showed a good response to PSMA radioligand therapy with tolerable side-effects after failure of guideline-compliant treatment.Due to recent developments, PSMA ligands will continue to play an important role in the management of prostate cancer patients and will be more widely used in the future.

More micrometastases, more recurrence? The role of qPCR of PSA mRNA in lymph nodes during prostatectomy.

Background And Objectives: Radical prostatectomy is a standard treatment for prostate cancer, yet about 30% of patients experience rising biochemical markers within a decade post-surgery. Pelvic lymph node sampling during prostatectomy assesses potential lymph node metastases, but standard histological assessments, which typically examine only 2-3 tissue sections, often miss occult metastases. This study assesses the effectiveness of qPCR in detecting PSA coding KLK3 mRNA for identifying lymph node metastases post-prostatectomy and explores the correlation between PSA-mRNA and biochemical recurrence.

Prostate cancer is a disease which poses an interesting clinical question: Should it be treated? Only a small subset of prostate cancers are aggressive and require removal and treatment to prevent metastatic spread. However, conventional diagnostics remain challenged to risk-stratify such patients; hence, new methods of approach to biomolecularly sub-classify the disease are needed. Here we use an unsupervised self-organising map approach to analyse live-cell Raman spectroscopy data obtained from prostate cell-lines; our aim is to exemplify this method to sub-stratify, at the single-cell-level, the cancer disease state using high-dimensional datasets with minimal preprocessing.

CXCL14 is a highly conserved chemokine expressed in various cell types, playing crucial roles in both physiological and pathological processes, including immune regulation and tumorigenesis. Recently, the role of CXCL14 in tumors has attracted considerable attention. However, previous pan-cancer studies have reported inconsistencies regarding the effects of CXCL14 on tumors, particularly concerning its expression levels in tumor tissues and its influence on various phenotypes of cancer cells.

Rationale And Objectives: Recently, the Response Evaluation Using PSMA PET/CT in Patients with Metastatic Castration-Resistant Prostate Cancer (RECIP 1.0) was proposed to better evaluate treatment response in prostate cancer patients using PET/CT with prostate-specific membrane antigen (PSMA) than more traditional approaches like metabolic PET evaluation response criteria in solid tumor (PERCIST 1.0).

Background: To determine outcomes of MRI-assisted radiosurgery (MARS) for salvage brachytherapy using the radioisotope Pd after various upfront treatments including surgery, external beam radiotherapy, and brachytherapy.
Methods: We retrospectively reviewed data for patients who underwent salvage MARS for intraprostatic lesions or prostate bed recurrences from 2016 to 2022. Biochemical recurrence, prostate cancer-specific, and overall survival, and the cumulative incidences of toxicities, were determined by Kaplan-Meier estimates.
