The alteration of long noncoding RNA (lncRNA) expression is significantly associated with the occurrence and progression of various human tumors.
Aim
To explore the possible mechanism by which lncRNA NPSR1-AS1 affects bladder cancer, as well as its diagnostic and prognostic value.
Material and methods
The data related to bladder cancer were mined from the GEO database. RT-qPCR was used to determine the expression of lncRNA NPSR1-AS1 and miR-199a-3p in BCa tissues, cell lines and urine. Cell proliferation, migration and apoptosis and other cell functions were tested in UMUC3, T24 and cells. The interactions between molecules were studied using the luciferase reporter gene, RIP and Spearman correlation analysis. ROC, K-M and COX regression analyses were used to evaluate the clinical value of lncRNA NPSR1-AS1.
Results
The lncRNA NPSR1-AS1 was expressed at higher levels in BCa tissue cell lines and urine, while miR-199a-3p expression of was decreased. The lncRNA NPSR1-AS1 affected the malignant biological behavior of BCa by sponging miR-199a-3p. Cell function experiments demonstrated that silencing lncRNA NPSR1-AS1 could inhibit the proliferation, migration and apoptosis of UMUC3, T24 and RT4 cells, while the inhibition of miR-199a-3p reversed this effect. Clinically, lncRNA NPSR1-AS1 may serve as a diagnostic and prognostic marker for BCa.
Conclusion
LncRNA NPSR1-AS1 targets miR-199a-3p and affects the progression of BCa. Moreover, it can serve as a biomarker for BCa.

[68Ga]/[18F] labeled Prostate Specific Membrane Antigen (PSMA) is the radiotracer of choice for imaging localized and metastatic prostate cancer with high sensitivity and specificity. On the other hand, 2-[18F]fluoro-D-glucose (FDG) Positron Emission Tomograpy/Computed Tomography (PET/CT) may help to evaluate the tumor heterogeneity in patients with metastatic castration-resistant prostate cancer (mCRPC) and determine treatment eligibility for Prostate Specific Membrane Antigen (PSMA) targeted radioligand therapy (PSMA-RLT) . The aim of the study is to evaluate the biochemical and clinical parameters which can predict the presence of FDG-PSMA discordant disease.
Material and Methods
A total of 70 advanced mCRPC patients who underwent [68Ga]Ga-PSMA-11 PET and FDG PET/CT between August 2016 and June 2021 were retrospectively analyzed. Inter-tumoral heterogeneity was both visually and semi-quantitatively evaluated. Baseline clinical, laboratory and PSMA PET/CT related semi-quantitative parameters were analyzed to predict FDG discordant disease with logistic regression analysis.
Results
29/70 (41.4%) of the patients had FDG-PSMA discordant disease. Overall 427 mismatch lesions (FDG+PSMA-) were detected: the majority of these lesions were in the bones (n = 236, 55.2%), lymph nodes (n = 95, 22.2%), and visceral organs (n = 88, 20.6%). Most significant parameters to predict FDG-PSMA discordant disease were liver metastases (HR= 26.5, 95%CI 2.3-302.9, P = 0.008) and serum AST (HR= 1.15, 95%CI 1.04-1.26, P = 0.007).
Conclusion
The presence of liver metastases and elevated AST may be easily used in clinical practice to predict FDG-PSMA discordant disease.

Background
The most common treatment for muscle-invasive bladder cancer (MIBC) is radical cystectomy (RC), typically combined with neoadjuvant and/or adjuvant therapy. This study aimed to describe patient characteristics, treatment patterns, recurrence, and overall survival (OS) among a contemporary cohort of patients with MIBC who underwent RC.
Methods
This retrospective study included adult patients with MIBC (T2-T4aN0M0/T1-T4aN1M0) who underwent RC between January 1, 2008 and July 31, 2023 and were captured in the U.S. ConcertAI Patient360™ Bladder Cancer electronic medical record database. Index date was defined as the date of RC. Recurrence (first evidence of disease following RC) and OS were analyzed using Kaplan-Meier methods and stratified by disease stage and treatment received. The association of recurrence with OS was assessed using Cox regression.
Results
A total of 783 RC-treated MIBC patients were included (median age 68 years; male 78.8%; White 87.6%; de novo MIBC 77.1%; pure urothelial histology 76.6%), with a median follow-up of 26.2 months. Neoadjuvant therapy use increased from 30.3% in 2011–2013 to 67.9% in 2020–2022. Among patients who received neoadjuvant therapy, 26.3% achieved pathological complete response (pT0N0) at RC. The 5-year recurrence and OS rates were 45.2% and 48.2%, respectively, varying by stage and treatments received. Mortality was 4.4 times higher [95% CI: 3.5, 5.6] among patients with recurrence compared with those without.
Conclusion
Despite increased utilization of perioperative therapy over the past 2 decades, MIBC patients undergoing RC continue to experience high rates of disease recurrence, which are associated with increased mortality.

Nonmuscle Invasive Bladder Cancer (NMIBC) is a prevalent malignancy marked by high recurrence and progression rates. Emerging evidence suggests that demographic and environmental factors may alter the bladder’s native oncobiome, influencing tumor behavior. This exploratory pilot study examined whether paired tumor and adjacent normal bladder mucosa exhibit distinct host transcriptomic and microbial signatures that may illuminate early tumor–microbiome interactions in NMIBC.
Methods
A meta-transcriptomic analysis was conducted on paired tumor and adjacent normal bladder mucosa from 6 NMIBC patients. Shotgun RNA sequencing was used to profile differential gene expression and microbial composition. Functional annotation and correlation analyses were performed to explore gene–microbe interactions.
Results
Fifty-seven differentially expressed genes (DEGs) across 6 patients and 12 paired samples were identified, including 45 downregulated and 12 upregulated genes, primarily involved in extracellular matrix organization and structural integrity. Tumor tissues exhibited significantly reduced microbial species richness compared to the adjacent normal mucosa (P = 0.026). Propionibacterium acnes showed increased abundance in tumor sites (23.88%) versus the adjacent normal mucosa (13%), suggesting a protumorigenic role. Veillonella dispar and Corynebacterium durum were strongly associated with matrix-regulating genes, while Bifidobacterium longum—more abundant in the adjacent normal tissues—correlated with genes linked to extracellular homeostasis, indicating a potential protective role.
Conclusion
This pilot study reveals distinct transcriptomic and microbial signatures in NMIBC, highlighting the role of microbial dysbiosis, which denotes an altered microbial community; reduced diversity and shifts in key taxa relative to the adjacent bladder mucosa, in extracellular matrix remodeling and tumor progression. These host–microbe interactions may contribute to disease pathogenesis and recurrence. Further studies are warranted to elucidate the underlying mechanisms and therapeutic implications.

Introduction
Single-dose intravesical gemcitabine therapy (IVGT) is a standard of care option following transurethral resection (TURBT) for low- to intermediate-risk nonmuscle invasive bladder cancer (NMIBC). The side-effect profile of IVGT has primarily focused on well-established urinary symptoms. Herein we present several cases of treatment-related alopecia following a single postoperative dose of IVGT for NMIBC.
Methods
Urologic oncologists from 7 high-volume bladder cancer referral centers in the United States were surveyed about incidents of alopecia, as well as the severity of hair loss, following a single postoperative dose of IVGT after TURBT- either for primary or for known NMIBC. Patients were identified either through self-reported concerns or by physician-observed alopecia during follow-up visits.
Results
Between January 2020 and December 2024, a total of 20 patients (6 male, 14 female) experienced hair loss, with the majority (N = 12, 60%) occurring within the first month post-TURBT. Thirteen of the 20 patients (65%) experienced severe alopecia. None of the patients were on medications known to cause hair loss or receiving other chemotherapy. Five patients had large resections (>5 cm), ten had medium (2–5 cm), and 5 had small (<2 cm) resections. Two patients had previously received IVGT without hair loss. Additionally, 4 patients had previously received intravesical Bacillus Calmette-Guérin (BCG), and 1 had received intravesical mitomycin C. No cases of bladder perforation were reported.
Conclusion
Hair loss appears to be an underreported side effect of IVGT post-TURBT. Patients should be counseled about this potential adverse event prior to treatment, and routine inquiry regarding alopecia should be considered in those undergoing IVGT post-TURBT. Prospective multicenter studies are encouraged to better evaluate the incidence and risk factors associated with this adverse event.

Multiparametric MRI (mpMRI) has reshaped prostate cancer diagnosis. However, Multiparametric MRI (mpMRI) often underestimates the tumor extent. Perilesional biopsy (PB) helps avoid excessive numbers of systematic biopsy (SB) cores. Nevertheless, there are concerns about the potential misses of contralateral clinically significant prostate cancer (csPCa). Despite ongoing research, a lack of high-quality studies remains. This scoping review examined the impact of PB in detecting csPCa, as well as the potential advantages and drawbacks of perilesional sampling compared to TB and systematic biopsy (SB) approaches. We conducted a PRISMA-based systematic search in Pubmed, Scopus, and WOS. We identified 77 articles, and nineteen PB studies were selected. Fourteen studies utilized an MRI-TRUS fusion software. Ten applied a sector-based or quadrant-based definition of perilesional sampling, and 8 adopted a precise mm-based definition, within a 5 mm or a ≤ 10 mm perilesional margin. We discovered a significant methodological diversity, particularly in terms of direct comparisons. Included studies recorded a wide range of csPCa detection rates (35%–99%). There were contradictory findings regarding the impact of PB on the detection rates of csPCa. Adding PB to TB decreased the detection of insignificant prostate cancer, the number of biopsy cores, and the upgrading rates in radical prostatectomy specimens. Six and 13 studies were rated as high- and moderate-risk of overall bias according to the ROBINS-I framework. Perilesional sampling during prostate biopsy is a promising yet immature strategy for detecting csPCa. The heterogeneity of methods and the lack of a standardized protocol hinder widespread adoption.

Purpose
Fusion prostate biopsy of prostate imaging report and data system lesions has become an integral part of diagnosis of prostate cancer. Though the scoring system is slightly different between peripheral zone and transition zone located lesions, a score of 4 or 5, regardless of lesion location is associated with a high or very high chance of clinically significant prostate cancer. Our goal is to examine whether lesion location impacts detection of clinically significant prostate cancer, defined as International Society of Urological Pathology grade group ≥2.
Materials and Methods
Multi-institutional retrospective review of patients who underwent MRI fusion biopsy at 3 tertiary care medical centers between 2017 and 2022. Lesion level review was performed to compare targeted biopsy results for PI-RADS 4 and 5 lesions located in the transition zone and peripheral zone. Primary outcome of interest was detection of clinically significant prostate cancer. Multivariable logistic regression analyses were performed to assess for predictors of clinically significant prostate cancer detection.
Results and Conclusions
Two thousand one hundred twenty eight lesions from 1,635 patients were included. On multivariate analysis, lesions located in the transition zone were independently associated with decreased detection of clinically significant prostate cancer (OR 0.55, P < 0.001). Similarly, detection of grade group 3 or higher prostate cancer was also lower for lesions in the transition zone (adjusted OR: 0.37; 95% CI: 0.26–0.54; P < 0.001). These differences have implications for further workup in patients with negative or low-grade pathology on MRI-TBx of PI-RADS 5 lesions and suggest a needs for reworking of the PI-RADS system.
目的融合前列腺活检的前列腺影像学报告和病变数据系统已成为前列腺癌诊断的重要组成部分。尽管外围区和过渡区病变的评分系统略有不同,但无论病变位置如何,得分为4或5分与临床显著性前列腺癌的高或非常高的可能性相关。我们的目的是检查病变位置是否影响临床显著性前列腺癌的检测,定义为国际泌尿外科病理学会分级≥2组。材料与方法对2017年至2022年在3个三级医疗中心接受MRI融合活检的患者进行多机构回顾性分析。病变水平复习,比较PI-RADS 4和5位于过渡区和外周区的病灶的靶向活检结果。研究的主要终点是检测出具有临床意义的前列腺癌。采用多变量logistic回归分析评估临床显著前列腺癌检测的预测因素。结果与结论共纳入1635例患者的2828个病变。在多变量分析中,位于过渡区的病变与临床显著性前列腺癌的检出率降低独立相关(OR 0.55, P < 0.001)。同样,在过渡区病变中,3级或更高级别前列腺癌的检出率也较低(校正or: 0.37; 95% CI: 0.26-0.54; P < 0.001)。这些差异对PI-RADS 5病变MRI-TBx阴性或低级别病理患者的进一步检查具有重要意义,并提示需要对PI-RADS系统进行改造。

Purpose
This retrospective comparative study aims to evaluate the safety and efficacy of a novel periurethral structural reinforcement (PSR) technique for enhancing early urinary continence recovery after laparoscopic radical prostatectomy (LRP).
Methods
Clinical records of 140 prostate cancer patients undergoing LRP between March 2022 to August 2023 were reviewed. Participants were divided into modified (PSR) and conventional (standard anastomosis) groups. The PSR technique augments standard posterior reconstruction by incorporating circumferential support sutures, aimed at reconstructing key surgical-damaged periurethral supports. Continence status (≤1 pad/day) were analyzed at catheter removal, 1, 2 4, and 12 weeks following surgery. Operative time, complications and pathologic characteristics were compared between 2 groups.
Results
Baseline characteristics were comparable among 2 groups. The modified group maintained superior continence recovery at all time intervals: 16.0% vs. 0% (immediate, P < 0.001), 20.0% vs. 6.7% (1 week, P = 0.018), 52.0% vs. 27.8% (4 weeks, P = 0.004), and 82.0% vs. 52.2% (12 weeks, P < 0.001), respectively. Complication rates showed no significant difference (P > 0.05).
Conclusion
The PSR technique is a safe and simple technique to accelerate early urinary continence recovery following LRP. Nevertheless, the generalizability of these outcomes require rigorous validation through a large-scale multicenter randomized controlled trial.
目的本回顾性比较研究旨在评价一种新型尿道周围结构强化(PSR)技术在腹腔镜根治性前列腺切除术(LRP)后早期尿失禁恢复中的安全性和有效性。方法回顾性分析2022年3月至2023年8月140例前列腺癌患者行LRP手术的临床资料。参与者分为改良吻合(PSR)组和常规吻合(标准吻合)组。PSR技术通过结合环支持缝合线来增强标准后路重建,旨在重建手术损伤的关键尿道周围支持。在拔管、术后1、2、4、12周分析尿失禁情况(≤1垫/天)。比较两组手术时间、并发症及病理特点。结果两组患者基线特征具有可比性。改良组在所有时间间隔均保持较好的尿失禁恢复:16.0% vs. 0%(即刻,P < 0.001), 20.0% vs. 6.7%(1周,P = 0.018), 52.0% vs. 27.8%(4周,P = 0.004), 82.0% vs. 52.2%(12周,P < 0.001)。并发症发生率无显著差异(P > 0.05)。结论PSR技术是一种安全、简便的加速LRP术后早期尿失禁恢复的技术。然而,这些结果的普遍性需要通过大规模多中心随机对照试验进行严格验证。
