Identification of genes involved in the transition from androgen-dependent to androgen-independent prostate cancer is important to extend our current knowledge of the disease. Using differential display RT-PCR analysis between androgen-dependent and androgen-independent prostate cancer cells, we have identified a novel gene, designated GC109. GC109 harbours a putative Cys-His cluster, a nuclear localisation signal, a leucine zipper and a ret finger protein (rfp)-like domain. GC109 mRNA expression in normal human tissues was found not to be restricted to the prostate. However, using a variety of 15 human cancer cell lines, GC109 mRNA was preferentially expressed in androgen-dependent LNCaP-FGC, compared with androgen-independent LNCaP-LNO, DU145 and PC3 human prostate cancer cells. Finally, the GC109 gene was mapped on human chromosome 2p24. Based on its protein domain structure and chromosomal localisation, we hypothesise that GC109 may be involved in chromosomal rearrangements in prostate cancer.

Objectives: This study aimed to assess postoperative decision regret (DR) after precision prostatectomy (PP), a novel subtotal surgical technique for prostate cancer (PCa) that involves the preservation of the unilateral capsule and seminal vesicle, and to identify factors predictive of DR after PP.
Materials And Methods: After a shared decision-making process, 128 patients underwent PP for the treatment of localised PCa. Given the subtotal nature of the surgery, patients were informed about the possibility of a detectable prostate-specific antigen and secondary treatment.
Objective: Transrectal (TR) prostate biopsy is being increasingly abandoned in favour of a transperineal (TP) approach as well as a targeted biopsy only of the index lesion(s). It remains underreported how these changes could impact concordance at final pathology. We aimed to evaluate the impact of transitioning from standard transrectal (sTR) to cognitive targeted transperineal (cog-tTP) biopsy on final pathology including concordance and upgrading.

Background: We present a systematic review and meta-analysis of randomized clinical trials (RCTs) with PARPi either as monotherapy or in combination with an androgen receptor-targeted agent (ARTA) in first- and second-line settings.
Methods: Primary endpoints are radiographic progression free survival (rPFS) and overall survival (OS) in patients with mCRPC and either unselected, homologous recombination repair wild-type (HRR-), homologous recombination repair mutated (HRR+) or with BRCA1, BRCA2, or ATM mutation. The effect of PARPi + ARTA in the second-line setting is also explored.
Clinical validation of a biopsy-based six-gene signature prognostic for aggressive prostate cancer.

Objectives: This study aimed to clinically validate the six-gene prognostic molecular clinical risk score (MCRS) for the prediction of aggressive prostate cancer in diagnostic biopsy tissue.
Methods: MCRS was evaluated in prostate biopsy tissue from a Swedish cohort of men with prostate cancer (UPCA, = 100). The primary outcome of adverse pathology and secondary outcomes of high primary Gleason (≥G4) and high pathological T-stage (≥T3) were assessed by likelihood ratio statistics and area under the receiver operating characteristic curves from logistic regression models; time to biochemical recurrence was assessed by likelihood ratio statistics and C-indexes from Cox proportional hazard regression models.
Objectives: To understand whether bladder outflow obstruction influences the association between traditional clinical predictive factors, particularly prostate-specific antigen (PSA) density and clinically significant prostate cancer (csPCa). This will help facilitate effective and evidence-based triaging of patients in rapid-access clinics.
Materials And Methods: We retrospectively analysed prospectively collected data from 307 suspected prostate cancer patients who underwent diagnostic biopsy from 2019 to 2023 at a single, high-volume, specialist cancer centre.
