A range of surgical approaches are available for treating benign prostatic hyperplasia (BPH), with emphasis placed not only on their effectiveness but also on minimizing invasiveness. The advent of surgical robotics has revolutionized BPH treatment, with robot-assisted simple prostatectomy offering a less invasive alternative to traditional approaches. The emergence of single-port systems has also earned attention for being effective in confined spaces. Aquablation represents a distinct robotic platform utilizing a heat-free, high-velocity waterjet to ablate prostate adenomas according to pre-registered configurations under real-time imaging. These novel technologies have proven to treat large prostates exceeding 80 mL efficiently and safely. Furthermore, Aquablation, along with technical modifications such as urethra-sparing robot-assisted simple prostatectomy, have demonstrated effectiveness in preserving ejaculatory function, thereby enhancing patients' overall quality of life. As evidence accumulates and technology and techniques evolve, robotic interventions for BPH may serve as a new standard in the field in the future.
治疗良性前列腺增生(BPH)有多种手术方法,其重点不仅在于其有效性,而且在于将侵入性降到最低。手术机器人的出现彻底改变了前列腺增生症的治疗,机器人辅助的简单前列腺切除术提供了一种比传统方法侵入性更小的选择。单端口系统的出现也引起了人们的注意,因为它在密闭空间中很有效。水消融是一种独特的机器人平台,利用无热、高速水射流在实时成像下根据预先登记的配置来消融前列腺腺瘤。这些新技术已被证明可以有效和安全地治疗超过80毫升的大前列腺。此外,水消融,连同技术改进,如保留尿道的机器人辅助简单前列腺切除术,已被证明在保留射精功能方面有效,从而提高患者的整体生活质量。随着证据的积累和技术的发展,机器人干预BPH可能会成为未来该领域的新标准。

Background

The necessity of prostate biopsy in patients with a Prostate Imaging–Reporting and Data System (PI-RADS) score below 3 and prostate-specific antigen (PSA) levels of 4–10 ng/ml remains controversial. We tested the diagnostic performance of the free PSA ratio (%fPSA) in detecting clinically significant cancer (CSC) in patients with PI-RADS <3 and PSA ≤10 ng/ml.

Methods

We analyzed 1435 prostate biopsies performed by a single operator between April 2018 and January 2023 at a single institution. PSA and free PSA results on the day of biopsy or within 1 month were used, and all biopsies were performed after prostate magnetic resonance imaging (MRI). CSC was defined as Gleason grade group ≥2.

Results

Among 208 men with PI-RADS <3 and PSA ≤10 ng/ml, CSC was detected in 37 (17.8%) patients. The median age was 65 years (interquartile range [IQR] 61–71), with a median PSA level of 5.06 ng/ml (IQR 3.98–7.08) and a median %fPSA of 18.2% (IQR 13.7–22.0). The area under the curve was 0.757 (95% confidence interval, 0.674–0.841), with a %fPSA cutoff of 17.6%, sensitivity of 86.5%, specificity of 63.7%, positive likelihood ratio (LR) of 2.38, and negative LR of 0.21. CSC was diagnosed in 5 out of 114 patients (4%) with %fPSA >17.6%, compared to 32 out of 94 patients (34%) with %fPSA <17.6%.

Conclusions

In patients with PI-RADS <3 and PSA ≤10 ng/ml, %fPSA values < 17.6% may facilitate early prostate cancer diagnosis in those who might not undergo biopsy based on MRI results alone. Additionally, unnecessary biopsies could be avoided in patients with elevated PSA levels when %fPSA exceeds 17.6%.
前列腺影像报告和数据系统(PI-RADS)评分低于3分且前列腺特异性抗原(PSA)水平为4-10 ng/ml的患者是否需要前列腺活检仍存在争议。我们测试了游离PSA比率(%fPSA)在PI-RADS <;3且PSA≤10 ng/ml患者中检测临床显著癌(CSC)的诊断性能。方法:我们分析了2018年4月至2023年1月在同一家机构由同一名操作员进行的1435例前列腺活检。采用活检当日或1个月内的PSA和游离PSA结果,所有活检均在前列腺磁共振成像(MRI)后进行。CSC定义为Gleason分级≥2组。结果在208例PI-RADS <;3且PSA≤10 ng/ml的男性中,有37例(17.8%)患者检出CSC。中位年龄为65岁(四分位数范围[IQR] 61-71),中位PSA水平为5.06 ng/ml (IQR 3.98-7.08),中位%fPSA为18.2% (IQR 13.7-22.0)。曲线下面积为0.757(95%可信区间为0.674 ~ 0.841),%fPSA截止值为17.6%,敏感性为86.5%,特异性为63.7%,阳性似然比(LR)为2.38,阴性似然比为0.21。114例%fPSA患者中有5例(4%)确诊为CSC,而94例%fPSA患者中有32例(34%)确诊为CSC,占17.6%。结论PI-RADS <;3和PSA≤10 ng/ml的患者,%fPSA值<;17.6%可能有助于那些可能不单独根据MRI结果进行活检的早期前列腺癌诊断。此外,当%fPSA超过17.6%时,PSA水平升高的患者可以避免不必要的活组织检查。

Background

Transperineal prostate biopsy offers advantage over a transrectal approach by reducing the risk of infectious complications. However, the necessity for antimicrobial prophylaxis (AP) before a transperineal prostate biopsy is less clear. This study aimed to study the rate of infectious complications following transperineal prostate biopsy with or without AP.

Materials and methods

Propensity score matching was done for 1,273 patients who underwent transperineal prostate biopsy between October 2020 and October 2024 to adjust for differences in covariates. Parameters including the rate of urinary tract infection (UTI) requiring or not requiring hospitalization between patients who received AP and those who did not receive AP were then compared.

Results

A total of 288 patients were matched for each group and baseline characteristics were balanced between groups. The overall incidence of UTI was very low in both groups without significant difference. UTI requiring hospitalization occurred in only one patient in the AP group (0.1%) and none in the non-AP group. Nonhospitalized UTI occurred in 0.7% of the AP group and 0.3% of the non-AP group (P = 1.000).

Conclusion

There was no significant difference in the rate of UTI based on the use or nonuse of AP prior to transperineal prostate biopsy. The overall incidence of UTI was very low regardless of the use of AP. Omission of AP prior to transperineal prostate biopsy might be possible, which would help promote antimicrobial stewardship.
背景:与经直肠入路相比,经会阴前列腺活检具有降低感染并发症风险的优势。然而,在经会阴前列腺活检前进行抗菌预防(AP)的必要性尚不清楚。本研究旨在研究经会阴前列腺活检伴或不伴ap后感染并发症的发生率。材料和方法对2020年10月至2024年10月期间接受经会阴前列腺活检的1273例患者进行倾向评分匹配,以调整协变量的差异。然后比较接受AP治疗和未接受AP治疗的患者需要或不需要住院的尿路感染(UTI)发生率。结果两组共匹配288例患者,组间基线特征平衡。两组尿路感染的总发生率均很低,无显著性差异。需要住院治疗的尿路感染在AP组中仅发生1例(0.1%),在非AP组中无一例。非住院UTI发生率为AP组的0.7%和非AP组的0.3% (P = 1.000)。结论经会阴前列腺活检前使用或未使用AP对尿路感染的发生率无显著性差异。无论是否使用AP,尿路感染的总体发生率都非常低。经会阴前列腺活检前可能遗漏AP,这将有助于促进抗菌药物的管理。

Introduction

Several institutions have reported their experience with outpatient robot-assisted radical prostatectomy (O-RARP). However, it is unclear if the utilization of this approach represents an improvement over inpatient robot-assisted radical prostatectomy (I-RARP). This meta-analysis sought to compare the surgical outcomes between O-RARP and I-RARP.

Methods

For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until April 30, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR guidelines. The risk ratio (RR) and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI).

Results

of the 297 retrieved abstracts, 12 underwent full-text review, and 11 studies were included in the final analysis, comprising a total cohort of 2,875 cases of robot-assisted radical prostatectomy (892 O-RARP cases and 1,983 I-RARP cases). Compared to I-RARP, the O-RARP group had lower mean operative time (MD = −9.4 minutes, 95% CI −15.1 to −3.7, P = 0.001), fewer overall postoperative complications (RR = 0.65, 95% CI 0.46 to 0.92, P = 0.017), shorter hospital stay (MD = −22.9 hours, 95% CI −26.0 to −19.7, P ≤ 0.001), and lower postoperative opioid requirements (RR = 0.45, 95% CI 0.28 to 0.71, P = 0.001). There were no significant differences in other outcomes, including: estimated blood loss, postoperative pain score, unscheduled visits after surgery, positive surgical margins, biochemical recurrence, International Prostate Symptom Score (IPSS) after surgery, or three- and six-month continence rates.

Conclusions

This meta-analysis demonstrates that O-RARP is a safe and feasible option for patients undergoing surgery for localized prostate cancer. Further studies are needed to better evaluate optimal patient selection, associated healthcare costs, and patient-reported outcomes.
几家机构报道了他们门诊机器人辅助根治性前列腺切除术(O-RARP)的经验。然而,目前尚不清楚这种方法的使用是否比住院机器人辅助根治性前列腺切除术(I-RARP)有改善。本荟萃分析旨在比较O-RARP和I-RARP的手术结果。方法检索PubMed、Scopus和Web of Science三个电子数据库,从其成立到2022年4月30日,检索相关文章。根据PRISMA 2020和AMSTAR指南报道了一项荟萃分析。采用风险比(RR)和加权平均差(MD)对二分变量和连续变量进行95%置信区间(CI)的比较。在297篇检索到的摘要中,12篇进行了全文综述,11项研究被纳入最终分析,包括2875例机器人辅助根治性前列腺切除术(892例O-RARP病例和1983例I-RARP病例)。与I-RARP相比,O-RARP组平均手术时间更短(MD = - 9.4分钟,95% CI为- 15.1至- 3.7,P = 0.001),术后总并发症更少(RR = 0.65, 95% CI为0.46至0.92,P = 0.017),住院时间更短(MD = - 22.9小时,95% CI为- 26.0至- 19.7,P≤0.001),术后阿片类药物需求更低(RR = 0.45, 95% CI为0.28至0.71,P = 0.001)。其他结果没有显著差异,包括:估计失血量、术后疼痛评分、术后未安排的就诊、手术边缘阳性、生化复发、术后国际前列腺症状评分(IPSS)或3个月和6个月的失禁率。结论:本荟萃分析表明,O-RARP对于局部前列腺癌手术患者是一种安全可行的选择。需要进一步的研究来更好地评估最佳患者选择、相关的医疗保健成本和患者报告的结果。

Background

This study aimed to evaluate the impact of preoperative prostate artery embolization (PAE) on intraoperative blood loss during transurethral resection of the prostate (TURP) in glands larger than 80 cc.

Material and methods

A prospective, surgeon-blinded randomized controlled clinical trial was conducted at a single tertiary center. Patients with a prostate volume of more than 80 cc with indications for TURP were randomized (1:1) to the following groups: preoperative prostatic artery embolization followed by TURP (Group A—intervention arm) and TURP alone (Group B—control arm). The primary outcome studied was blood loss measured as the drop in hemoglobin level postoperatively, and the secondary outcome measured was resection efficiency (resected weight per min) and postoperative complication rate.

Results

Our study included 10 patients each in group, A and B. The median prostate volume was 119 mL and 140 mL and the median preoperative hemoglobin was 13.3 g/dL (interquartile range: 12.5 – 14.3 g/dL) and 14.4 g/dL (interquartile range: 10.1–15.2 g/dL) in groups A and B, respectively. Change in postoperative hemoglobin was significantly greater in Group B than in Group A (−1.4 g/dL versus +0.5 g/dL, P = 0.015). There were no significant differences in the weight of resected prostate chips (52 g versus 73 g, P = 0.089) and resection efficiency (0.7 g/min versus 0.6 g/min, P = 0.853) between groups A and B. Two patients in Group B received one unit of red blood cell transfusion compared to only 1 patient in Group A (P = 1.000). One patient from each group had to be brought back to the operation room for hemostasis.

Conclusion

Our study demonstrated that preoperative prostate artery embolization reduces intraoperative blood loss in men with large prostates undergoing TURP but did not impact resection efficiency or complication rate.
本研究旨在评估术前前列腺动脉栓塞(PAE)对大于80cc腺体经尿道前列腺切除术(TURP)术中出血量的影响。材料和方法在单一三级中心进行了一项前瞻性,手术盲随机对照临床试验。前列腺体积大于80cc且有TURP适应症的患者按1:1的比例随机分为以下两组:术前前列腺动脉栓塞后行TURP治疗组(a组干预组)和单独行TURP治疗组(b组对照组)。研究的主要终点是术后血红蛋白水平下降的出血量,次要终点是手术切除效率(每分钟切除重量)和术后并发症发生率。结果A组和B组各10例患者,前列腺体积中位数分别为119 mL和140 mL,术前血红蛋白中位数分别为13.3 g/dL(四分位数范围:12.5 ~ 14.3 g/dL)和14.4 g/dL(四分位数范围:10.1 ~ 15.2 g/dL)。B组术后血红蛋白变化明显大于A组(- 1.4 g/dL vs +0.5 g/dL, P = 0.015)。A组和B组在切除的前列腺芯片重量(52 g对73 g, P = 0.089)和切除效率(0.7 g/min对0.6 g/min, P = 0.853)方面无显著差异。B组2例患者接受1单位红细胞输血,而A组只有1例患者接受1单位红细胞输血(P = 1.000)。两组各有一名患者被带回手术室进行止血。结论本研究表明术前前列腺动脉栓塞可减少大前列腺行TURP患者术中出血量,但不影响手术效率和并发症发生率。

Background

Gallium-68 prostate-specific membrane-antigen positron emission tomography/computed tomography (68Ga-PSMA-11 PET/CT) has recently emerged as a novel imaging modality, potentially improving oncologic outcomes for prostate cancer patients. This study aimed to assess the potential predictive factors associated with 68Ga-PSMA-11 PET/CT positivity following persistent prostate-specific antigen (PSA) levels and primary biochemical recurrence post-radical prostatectomy (RP), focusing on prostate specimen characteristics. Furthermore, we aim to identify predictive factors for locoregional recurrence.

Methods

We conducted a retrospective analysis of 230 prostate cancer patients treated with RP and without prior salvage or adjuvant radiotherapy or systemic treatments. All patients underwent 68Ga-PSMA-11 PET/CT scans to detect prostate cancer recurrence detection. Pathological findings were carefully examined and correlated with 68Ga-PSMA-11 PET/CT positivity and locoregional recurrence.

Results

Our analysis showed that 68Ga-PSMA-11 PET/CT positivity was associated with International Society of Urological Pathology (ISUP) grade group ≥3, presence of positive lymph node invasion at the time of RP, positive extra-prostatic extension, involvement of seminal vesicles and post-RP PSA levels ≥0.1 ng/ml. Additionally, we identified ISUP grade group 2 and ISUP grade group ≥3, whether with or without positive lymph node invasion, along with extra-prostatic extension, involvement of seminal vesicles and post-RP PSA ≥0.1 ng/ml were identified as factors associated with pelvic node recurrence.

Conclusion

Pathological findings emerge as robust predictors of 68Ga-PSMA-11 PET/CT positivity and locoregional recurrences in cases of initial biochemical recurrence or persistence without prior adjuvant or salvage treatment. This diagnostic approach facilitates potential adjustments in management strategies, such as PSMA-guided radiotherapy or PSMA-guided lymphadenectomy.
镓-68前列腺特异性膜抗原正电子发射断层扫描/计算机断层扫描(68Ga-PSMA-11 PET/CT)最近成为一种新的成像方式,可能改善前列腺癌患者的肿瘤预后。本研究旨在评估68Ga-PSMA-11 PET/CT阳性与持续性前列腺特异性抗原(PSA)水平和根治性前列腺切除术(RP)后原发性生化复发相关的潜在预测因素,重点关注前列腺标本特征。此外,我们的目标是确定局部复发的预测因素。方法回顾性分析230例RP治疗的前列腺癌患者,这些患者之前没有接受过抢救或辅助放疗或全身治疗。所有患者均行68Ga-PSMA-11 PET/CT扫描检测前列腺癌复发。仔细检查病理结果,并与68Ga-PSMA-11 PET/CT阳性和局部复发相关。结果68Ga-PSMA-11 PET/CT阳性与国际泌尿病理学会(ISUP)分级≥3级、RP时淋巴结浸润阳性、前列腺外延伸阳性、累及精囊、RP后PSA水平≥0.1 ng/ml相关。此外,我们确定ISUP 2级组和ISUP≥3级组,无论是否伴有淋巴结浸润阳性,以及前列腺外延伸、精囊受损伤和rp后PSA≥0.1 ng/ml,都被确定为盆腔淋巴结复发的相关因素。结论病理表现是68Ga-PSMA-11 PET/CT阳性和局部复发的可靠预测因子,在初始生化复发或未进行辅助或挽救治疗的情况下持续存在。这种诊断方法有助于调整治疗策略,如psma引导的放射治疗或psma引导的淋巴结切除术。

Background

Clinical significance of primary tumor progression in patients with metastatic hormone-sensitive prostate cancer (mHSPC) is unclear.

Methods

Clinical data from 987 patients with mHSPC from multiple institutions between September 1999 and November 2023 were reviewed. The prognostic impact of primary tumor progression was examined along with other clinical parameters. Castration-resistant prostate cancer progression-free survival (CRPC PFS) and overall survival (OS) were analyzed as clinical outcomes. Student's t-test, Cox proportional hazards models, and Kaplan-Meier methods were utilized to validate the clinical significance.

Results

The median age and initial prostate-specific antigen (iPSA) values were 74 and 221 ng/ml, respectively. 632 (64%) and 355 (36%) patients had clinical T stage ≤3 and 4 at diagnosis, respectively. mHSPC patients with clinical T stage 4 were more likely to have a higher grade group (GG), higher frequency of lymph node metastasis, lower hemoglobin (Hb), and more high-volume/risk disease in comparison with those with clinical T stage ≤3. Patients with cT4 were associated with shorter CRPC PFS (P=0.0002) and OS (P < 0.0001). Multivariate analysis identified cT4 as an independent prognostic factor for OS (HR=1.33, P=0.03) along with age, GG, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), albumin (Alb), and high-volume disease. After propensity score matching, patients with cT4 had unfavorable OS in comparison with those with ≤cT3 (P=0.0279). Furthermore, when combined with tumor volume, men with low-volume + cT4 achieved a prognosis comparable to that of patients with high-volume+≤cT3 and high-volume + cT4 (P=0.6876 and P=0.1679, respectively).

Conclusion

Bulkiness of primary prostate tumor was associated with worse outcomes in patients with mHSPC. Men with cT4 will require multimodal and intensive therapeutic strategies irrespective of tumor volume.
转移性激素敏感前列腺癌(mHSPC)患者原发肿瘤进展的临床意义尚不清楚。方法回顾1999年9月至2023年11月来自多家机构的987例mHSPC患者的临床资料。原发肿瘤进展对预后的影响与其他临床参数一起进行了检查。分析去势抵抗性前列腺癌无进展生存期(CRPC PFS)和总生存期(OS)作为临床结局。采用学生t检验、Cox比例风险模型和Kaplan-Meier方法验证临床意义。结果中位年龄和初始前列腺特异性抗原(iPSA)值分别为74和221 ng/ml。632例(64%)和355例(36%)患者在诊断时临床T期≤3期和4期。与临床T期≤3的mHSPC患者相比,临床T期4的mHSPC患者更有可能出现更高的分级组(GG)、更高的淋巴结转移频率、更低的血红蛋白(Hb)和更多的高容量/危险疾病。cT4患者与较短的CRPC PFS (P=0.0002)和OS (P <;0.0001)。多因素分析发现cT4与年龄、GG、乳酸脱氢酶(LDH)、碱性磷酸酶(ALP)、白蛋白(Alb)和大容量疾病一起是OS的独立预后因素(HR=1.33, P=0.03)。倾向评分匹配后,与≤cT3的患者相比,cT4患者的OS较差(P=0.0279)。此外,当结合肿瘤体积时,低体积+ cT4患者的预后与高体积+≤cT3和高体积+ cT4患者相当(P=0.6876和P=0.1679)。结论mHSPC患者原发性前列腺肿瘤体积大与预后差相关。无论肿瘤体积大小,cT4患者需要多模式和强化治疗策略。

Background

The causal relationships between the gut microbiota and prostate cancer, prostatitis, and benign prostatic hyperplasia remain uncertain. We intend to identify the causal connections between the gut microbiota and prostatic diseases and investigate the potential mechanisms involved.

Methods

A two-sample Mendelian randomization (MR) analysis was conducted to elucidate the impact of 196 gut microbiota on prostatic diseases risk. Reverse MR, linkage disequilibrium regression score (LDSC), and colocalization analyses were performed to strengthen causal evidence. Phenome-wide MR (Phe-MR) analysis was used to evaluate the potential side effects of targeting the detected gut microbiota. We designed a two-step MR study to assess the mediating effects of sex hormones, blood metabolites, and proteins.

Results

According to the MR analyses, 31 bacterial taxa were causally associated with prostatic diseases, of which 23 types were newly identified. In addition, Alphaproteobacteria restrained prostate cancer, Ruminococcaceae UCG009 prevented prostatitis, and Clostridiales posed a risk for benign prostatic hyperplasia. LDSC and colocalization analyses indicated that the detected associations were not confounded by genetic correlation or LD from common causal loci. In the mediation analysis, we identified 53 mediators linking the gut microbiota to prostatic diseases, with a specific emphasis on the critical roles played by sex hormones and blood metabolites, and identified 34 proteins that may be used as therapeutic targets, especially FGFR1 and XPNPEP1.

Conclusions

Our study represents the first comprehensive exploration of the causal effects of the gut microbiota on prostatic diseases and reveals the mediating effects of sex hormones and blood metabolites on the “gut-prostate axis.”
背景:肠道菌群与前列腺癌、前列腺炎和良性前列腺增生之间的因果关系尚不清楚。我们打算确定肠道微生物群和前列腺疾病之间的因果关系,并研究可能涉及的机制。方法采用双样本孟德尔随机化(MR)分析,探讨196种肠道菌群对前列腺疾病风险的影响。反向磁共振、连锁不平衡回归评分(LDSC)和共定位分析来加强因果证据。使用全现象MR (Phe-MR)分析来评估针对检测到的肠道微生物群的潜在副作用。我们设计了一项两步磁共振研究来评估性激素、血液代谢物和蛋白质的中介作用。结果31个细菌类群与前列腺疾病相关,其中新发现23个。此外,Alphaproteobacteria抑制前列腺癌,Ruminococcaceae UCG009预防前列腺炎,Clostridiales具有良性前列腺增生的风险。LDSC和共定位分析表明,检测到的关联不会被遗传相关或来自共同因果位点的LD混淆。在中介分析中,我们确定了53种将肠道微生物群与前列腺疾病联系起来的介质,特别强调性激素和血液代谢物所起的关键作用,并确定了34种可能用作治疗靶点的蛋白,特别是FGFR1和XPNPEP1。结论sour研究首次全面探讨了肠道菌群与前列腺疾病的因果关系,揭示了性激素和血液代谢物在“肠-前列腺轴”中的中介作用。

Background

Transrectal prostate biopsy is a commonly performed urological procedure in which antibiotic prophylaxis is recommended. Fluoroquinolone-type antibiotics are no longer acceptable in the EU. Fosfomycin-trometamol may be used, but there is no evidence regarding its ideal dose and administration time.

Methods

Patients who underwent prostate biopsy between 2021 and 2023 were evaluated prospectively. 204 patients were randomized into two arms: 102 patients (Arm A) received a single-dose of fosfomycin-trometamol one hour before surgery, and 102 patients (Arm B) received one additional dose of fosfomycin-trometamol 48 hours after the first dose. Urine tests and questionnaires were administered during the postoperative period and the subsequent four weeks to identify any symptoms, infectious, or other complications.

Results

There was no statistical difference in the rate of asymptomatic bacteriuria (4.90% (5) vs. 8.82% (9), P = 0.27) symptomatic urinary tract infection (0% (0) vs. 1.96% (2), P = 0.50), or febrile urinary tract infection (0% (0) vs. 0.98% (1), P = 1) between the groups. Only hematuria was significantly more common in Arm B (6.86% (7) vs. 16.67% (17), P = 0.03), whereas other complications did not differ significantly. There was no statistical difference in hospitalization (0.98% (1) vs. 2.94 (3), P = 0.62) or mortality rate (0 % (0) vs. 0.98% (1), P = 1). Sub-group analysis of previous antibiotic users showed no difference in terms of complications.

Conclusion

There is no significant difference in infectious complications between single-dose and prolonged prophylaxis of fosfomycin-trometamol for transrectal prostate biopsy. A single-dose of fosfomycin one hour before biopsy is an ideal choice with a better ecological impact compared with prolonged antibiotic prophylaxis for transrectal prostate biopsy.
背景:经直肠前列腺活检是一种常用的泌尿外科手术,建议使用抗生素预防。氟喹诺酮类抗生素在欧盟已不再被接受。可以使用磷霉素-曲美他醇,但没有关于其理想剂量和给药时间的证据。方法前瞻性评估2021 - 2023年间接受前列腺活检的患者。204例患者被随机分为两组:102例患者(A组)在手术前1小时接受单剂量磷霉素-曲美他醇治疗,102例患者(B组)在手术前48小时后接受一剂量磷霉素-曲美他醇治疗。在术后和随后的四周内进行尿检和问卷调查,以确定任何症状、感染或其他并发症。结果两组无症状菌尿发生率(4.90%(5)比8.82% (9),P = 0.27)、有症状尿路感染发生率(0%(0)比1.96% (2),P = 0.50)、发热性尿路感染发生率(0%(0)比0.98% (1),P = 1)差异无统计学意义。只有血尿在B组更为常见(6.86%(7)比16.67% (17),P = 0.03),而其他并发症无显著差异。住院率(0.98%(1)比2.94 (3),P = 0.62)和死亡率(0%(0)比0.98% (1),P = 1)无统计学差异。既往抗生素使用亚组分析显示并发症无统计学差异。结论经直肠前列腺活检单剂量预防与长期预防磷霉素-曲美他醇感染并发症无显著性差异。活检前1小时单剂量磷霉素是理想的选择,与经直肠前列腺活检的长期抗生素预防相比,具有更好的生态影响。

Purpose

This study aimed to assess the incidence, severity, and onset of dermatologic adverse events (dAEs) in Korean patients treated with apalutamide for metastatic hormone-sensitive prostate cancer (mHSPC) and to identify clinical and laboratory predisposing factors.

Materials and methods

We retrospectively analyzed data of patients treated with apalutamide for mHSPC at a tertiary referral center in Korea between April 2023 and March 2024. Patients with a radical prostatectomy history or insufficient data were excluded. The onset, severity, and management of dAEs were evaluated and compared between patients with and without dAEs. Clinical and laboratory data from 1 month prior to apalutamide administration were collected. Logistic regression was performed to identify predictors of dAEs, and the predictive value of serum albumin levels was analyzed using the receiver operating characteristic (ROC) curve.

Results

Twenty-six (40.0%) of the 65 patients developed dAEs, including nine (13.8%) with Grade ≥3 events. The median onset of dAEs was 66.5 (45–78) days. Patients with dAEs had significantly lower initial prostate-specific antigen levels (70.4 vs. 301.6 ng/mL), higher Eastern Cooperative Oncology Group Performance Status (ECOG-PS; 30.8% vs. 5.1%), and lower serum albumin levels (3.8 vs. 4.1 g/dL). Logistic regression identified elevated Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) and hypoalbuminemia as significant predictors of dAEs. ROC analysis for serum albumin levels produced an area under the curve of 0.739, with a cutoff value of 3.85 g/dL, yielding a sensitivity and specificity of 65.4% and 74.4%, respectively.

Conclusion

dAEs are prevalent in Korean patients treated with apalutamide for mHSPC, with ECOG-PS and serum albumin levels identified as significant risk factors.
目的:本研究旨在评估韩国接受阿帕鲁胺治疗转移性激素敏感性前列腺癌(mHSPC)患者皮肤不良事件(dAEs)的发生率、严重程度和发作情况,并确定临床和实验室易感因素。材料和方法我们回顾性分析了2023年4月至2024年3月在韩国一家三级转诊中心接受阿帕鲁胺治疗mHSPC的患者的数据。排除有根治性前列腺切除术史或资料不充分的患者。评估和比较dAEs患者和非dAEs患者的发病、严重程度和管理。收集阿帕鲁胺给药前1个月的临床和实验室数据。采用Logistic回归确定dAEs的预测因素,并采用受试者工作特征(ROC)曲线分析血清白蛋白水平的预测值。结果65例患者中有26例(40.0%)发生dAEs,其中9例(13.8%)发生≥3级事件。dae的中位发病时间为66.5(45-78)天。dAEs患者的初始前列腺特异性抗原水平明显降低(70.4 vs 301.6 ng/mL),东部肿瘤合作组性能状态(ECOG-PS;30.8%对5.1%),血清白蛋白水平较低(3.8对4.1 g/dL)。Logistic回归发现东部肿瘤合作组绩效状态(ECOG-PS)升高和低白蛋白血症是dAEs的重要预测因素。对血清白蛋白水平进行ROC分析,曲线下面积为0.739,截断值为3.85 g/dL,敏感性和特异性分别为65.4%和74.4%。结论在韩国接受阿帕鲁胺治疗mHSPC的患者中,daes普遍存在,ECOG-PS和血清白蛋白水平被认为是重要的危险因素。
