    Abstract Purpose of review: Urinary incontinence is common postoperative complication following robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa). Despite the increasing adoption of RARP in the treatment of high-risk PCa (HRPC), concerns persist regarding the adequacy of reported continence outcomes in this subgroup. This review aims to illuminate the state of continence recovery in HRPC patients post-RARP.
    Recent findings: Urinary continence (UC) recovery rates in HRPC was reported to be lower than the intermediate/low-risk counterparts from 6 to 24 months post-RARP. Predictive models showed that age, obesity, race, disease status, and surgical approaches represent predictors of continence recovery. Special techniques like NeuroSAFE technique and Retzius-Sparing approach also play a role in reducing incontinence also in the high-risk scenario.
    Summary: RARP for HRPC appears to be associated with worse continence compared with other risk groups. A multimodality approach for prediction and prevention of incontinence after RARP is vital. Further research into this area is necessary to enhance continence recovery outcomes in HRPC patients undergoing RARP.

    Abstract Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) affects extra-respiratory systems, with small-scale studies showing worsened male lower urinary tract symptoms (LUTS) after coronavirus disease 2019 (COVID-19). This study explores the correlation between SARS-CoV-2 infection and male benign prostatic hyperplasia (BPH) complications using large-scale real world data.
    Materials and methods: All male patients attending the public healthcare system in Hong Kong receiving alpha-blocker monotherapy for LUTS from 2021 to 2022 were included in this study. Patients with and without positive polymerase chain reaction (PCR) test for SARS-CoV-2 are selected as the exposure group and control group, respectively. Baseline characteristics are retrieved, with propensity score matching performed to ensure balance of covariates between the two groups. BPH complications were then compared and subgroup analyses were performed.
    Results: After propensity score matching, 17,986 patients were included for analysis, among which half had PCR-confirmed SARS-CoV-2 infection (n = 8993). When compared to controls, the SARS-CoV-2 group demonstrated statistically significant higher incidence of retention of urine (4.55% vs. 0.86%, p < 0.001), haematuria (1.36% vs. 0.41%, p < 0.001), clinical urinary tract infection (UTI) (4.31% vs. 1.49%, p < 0.001), culture-proven bacteriuria (9.02% vs. 1.97%, p < 0.001) and addition of 5ARI (0.50% vs. 0.02%, p < 0.001). Subgroup analysis demonstrated similar differences across different age groups. There are no statistically significance differences in incidence of retention, haematuria, or addition of 5ARI across different COVID-19 severities.
    Conclusions: SARS-CoV-2 infection is associated with increased incidence of urinary retention, haematuria, UTI and the addition of combination therapy in the short term, regardless of COVID-19 severity. This is the largest study demonstrating the detrimental urological effects of SARS-CoV-2 infection.

    Abstract Purpose: The study aimed at investigating prostate cancer patients' choice of androgen deprivation treatment (ADT) and possible factors that would affect their preferences of ADT.
    Methods: This was a single-centre cross-sectional study investigating the usage and preferences of ADT. Consecutives prostate cancer patients who were receiving injectable luteinizing hormone-releasing hormone (LHRH) agonist or antagonist were recruited from the prostate cancer clinic in a tertiary academic hospital. Patients who received bilateral orchidectomy or those who could not consent to the study were excluded. Disease characteristics, treatment information and patient background were documented. The survey collected information related to their change in ADT regimen, preferences on drug usage (routes and frequency of administration) and their reasons. A hypothetical set of three drug formularies was designed. Questions regarding patient preference and the contributing reasons raised in the format of questionnaire.
    Results: 100 patients completed the survey. Most patients started with more frequent injections (3-monthly, 54%; 1-monthly, 38%) and switched to 6-monthly injections (89%) at the time of the survey. Primary reasons for the change were healthcare opinion (72%) and less frequent treatment (51%). Three options of ADT (oral daily, 1-monthly and 6-monthly injection) with the same efficacies and side effect profile were offered: 61% preferred 6-monthly injection, 1% preferred 1-monthly injection and 38% preferred oral regimen. When patients were informed of lower cardiovascular side effects in 1-monthly injection or daily oral drug, patients' preference was 56% (6-monthly), 6% (1-monthly), and 39% (oral). Patients with polypharmacy (more than 5 regular medications) were more inclined to choose injections (p = 0.025). Patient age, educational background, employment status, marriage status and disease status were not found to be statistically significant contributing factors to patient preference.
    Conclusion: 6-monthly ADT injection was the preferred ADT despite greater cardiovascular risks. Among 1-monthly or daily oral LHRH antagonist, more patients prefer oral option. Convenience factor was highly valued.

    Abstract Prostate cancer (PCa) is a prevalent malignant disease and the primary reason for cancer-related mortality among men globally. GLIS1 (GLIS family zinc finger 1) is a key regulator in various pathologies. However, the expression pattern, clinical relevance, and immunomodulatory function of GLIS1 in PCa remain unclear. In this study, GLIS1 was discovered to serve as a key gene in PCa by integrating mRNA and miRNA expression profiles from GEO database. We systematically explored the expression and prognostic values of GLIS1 in cancers using multiple databases. Additionally, we examined the functions of GLIS1 and the relationship between GLIS1 expression levels and immune infiltration in PCa. Results showed that GLIS1 was differentially expressed between normal and tumor tissues in various cancer types and was significantly low-expressed in PCa. Low GLIS1 expression was associated with poor PCa prognosis. GLIS1 was also involved in the activation, proliferation, differentiation, and migration of immune cells, and its expression showed a positive correlation with the infiltration of various immune cells. Moreover, GLIS1 expression was positively associated with various chemokines/chemokine receptors, indicating the involvement in regulating immune cell migration. In summary, GLIS1 is a potential prognostic biomarker and a therapeutic target to modulate anti-tumor immune response in PCa.

    Abstract This study aimed to report the outcomes of active surveillance (AS) in the management of low-risk prostate cancer (PCa). It recruited 87 men who were prospectively followed up according to the Prostate Cancer Research International Active Surveillance (PRIAS) protocol with local adaptation at SH Ho Urology Centre, Prince of Wales Hospital, Hong Kong, China. We investigated the predictors of disease progression and found that baseline prostate-specific antigen density (PSAD) and the presence of the highest Prostate Imaging-Reporting and Data System (PI-RADS) score 5 lesion on magnetic resonance imaging (MRI) are significantly correlated with disease progression. Moreover, men with PSAD >0.2 ng ml-2 or PI-RADS 4 or 5 lesions had significantly worse upgrading-free survival compared to those with PSAD ≤0.2 ng ml-2 and PI-RADS 2 or 3 lesions. The study concludes that AS is a safe and effective management strategy for selected patients to defer radical treatment and that most disease progression can be detected after the first repeated biopsy. The combination of PSAD >0.2 ng ml-2 and PI-RADS 4 or 5 lesions may serve as a useful predictor of early disease progression and provide a guide to optimize follow-up protocols for men in different risk groups.

    Abstract Purpose: In the era of concurrent combination therapy in metastatic hormone sensitive prostate cancer, the impact of the testosterone level before initiating androgen deprivation therapy on treatment outcome is still uncertain. We aimed to investigate its effect on time-to-castration-resistance in a metastatic hormone sensitive prostate cancer cohort.
    Methods: This is a multi-center retrospective study of 5 databases from China, Japan, Austria and Spain including 258 metastatic hormone sensitive prostate cancer patients with androgen deprivation therapy initiated between 2002 and 2021. Baseline testosterone was divided into high and low groups using 12 nmol/L as cutoff level. Primary outcome was time-to-castration-resistance. Secondary outcomes were survival functions. Kaplan-Meier method was employed to evaluate the correlation between baseline testosterone and time-to-castration-resistance. Subgroup analysis was performed to elucidate the effect of upfront combination-therapy and metastatic volume.
    Results: Median age was 72 years. Median follow-up time was 31 months. Median pre-treatment prostate-specific-antigen level was 161 ng/mL. Majority of case were graded as International-Society-of-Urological-Pathology grade 5 (63.6%). 57.8% patients had high volume disease and 69.0% received upfront combination treatment. 44.6% of the cohort developed castration-resistance. The low testosterone group demonstrated shorter mean-time-to-castration-resistance (19.0
    Conclusions: Lower pre-treatment testosterone level is correlated to shorter time-to-castration resistance and worse survival in metastatic prostate cancer patients without upfront combination therapy. Those with low baseline testosterone should be encouraged to adopt combination therapy to delay progression.

    Abstract Background and objective: Treatment preference regarding apalutamide versus enzalutamide in prostate cancer (PCa) and the factors influencing decisions are largely unknown. Our aim was to investigate the preference for apalutamide versus enzalutamide among prostate cancer patients and their physicians and caregivers, and factors influencing their decision.
    Methods: This was a prospective, open-label, randomized, crossover trial. Patients with recurrence of localized PCa or with metastatic disease not considered as high-risk or high-volume and on continued androgen deprivation therapy were recruited. All subjects received a trial of two agents, apalutamide (A) and enzalutamide (E), for 12 wk each, with a 5-wk washout period in between. The sequencing of the drugs was randomized. The primary outcome was patient preference for one the drugs, assessed at the end of the study. Other outcomes included factors influencing patient preference, a comparison of side-effect profiles, and patients' quality of life (QoL). Physician and caregiver preferences for the drugs and factors affecting their choice were also assessed.
    Key findings and limitations: A total of 74 patients met the eligibility criteria and were randomized to the A → E or E → A arm. Of these, 66 patients (89.1%; 32 A → E, 34 E → A) completed the study. Baseline characteristics were comparable between the two groups, and ∼90% of the patients had low-volume metastatic disease. After completion of both treatments for 12 wk each, the difference in preference for A over E was 17.8%, with similar trends for preference of A over E among physicians (18.2%) and caregivers (22.4%). Fewer side effect was the most critical factor influencing the preference of patients. Among the side effects, less fatigue was the benefit of A over E most frequently reported. No notable difference in QoL was observed between the two drugs. However, the study was terminated on interim analysis and the results might not be conclusive.
    Conclusions: There was a trend for preference of A over E among patients with predominantly low-volume recurrent or metastatic PCa and their physicians and caregivers. Fewer side effects was the most critical factor influencing their choice.
    Patient summary: Patients with low-volume recurrent or metastatic prostate cancer tended to prefer treatment with apalutamide over enzalutamide. Side effects were the most critical factor influencing treatment preference.
