晚期前列腺癌
  • 文章类型: Journal Article
    雄激素剥夺疗法(ADT)和雄激素受体途径抑制剂(ARPi)的强化治疗可改善晚期前列腺癌的生存率。然而,ADT与显著的心血管毒性有关,ARPi也对心血管健康产生负面影响。再加上在诊断时前列腺癌幸存者中报告的基线心血管危险因素的患病率较高,迫切需要在这一人群中优先考虑和优化心血管健康。首先,虽然没有专用的心血管毒性风险计算器可用,SCORE2等其他工具可用于基线心血管风险评估.接下来,接受联合治疗的选定患者可能受益于ADT的降级,从而在维持癌症控制的同时将其毒性降至最低.这些患者的特点是对激素治疗有特殊的PSA反应,有利的疾病特征和相互竞争的合并症,需要不太积极的治疗方案。此外,新兴的分子和基因组生物标志物具有鉴别适合ADT或ARPi降级治疗方法的患者的潜力.一种这样的生物标志物是预测对ARPi的抗性的AR-V7剪接变体。最后,通过连贯框架(ABCDE)和运动疗法优化患者可改变的心血管危险因素同样重要.本文旨在全面回顾激素治疗对转移性激素敏感型前列腺癌的心血管影响。提出总体策略,以减轻与激素治疗相关的心血管毒性,and,最重要的是,提高对我们当前涉及激素药物的管理策略固有的有害心血管影响的认识。
    Treatment intensification with androgen deprivation therapy (ADT) and androgen receptor pathway inhibitors (ARPi) have led to improved survival in advanced prostate cancer. However, ADT is linked to significant cardiovascular toxicity, and ARPi also negatively impacts cardiovascular health. Together with a higher prevalence of baseline cardiovascular risk factors reported among prostate cancer survivors at diagnosis, there is a pressing need to prioritise and optimise cardiovascular health in this population. Firstly, While no dedicated cardiovascular toxicity risk calculators are available, other tools such as SCORE2 can be used for baseline cardiovascular risk assessment. Next, selected patients on combination therapy may benefit from de-escalation of ADT to minimise its toxicities while maintaining cancer control. These patients can be characterised by an exceptional PSA response to hormonal treatment, favourable disease characteristics and competing comorbidities that warrant a less aggressive treatment regime. In addition, emerging molecular and genomic biomarkers hold the potential to identify patients who are suited for a de-escalated treatment approach either with ADT or with ARPi. One such biomarker is AR-V7 splice variant that predicts resistance to ARPi. Lastly, optimization of modifiable cardiovascular risk factors for patients through a coherent framework (ABCDE) and exercise therapy is equally important. This article aims to comprehensively review the cardiovascular impact of hormonal manipulation in metastatic hormone-sensitive prostate cancer, propose overarching strategies to mitigate cardiovascular toxicity associated with hormonal treatment, and, most importantly, raise awareness about the detrimental cardiovascular effects inherent in our current management strategies involving hormonal agents.

    背景:这项定性研究旨在开发一种新颖的,全面,患者报告结果测量(PRO),“前列腺癌雄激素剥夺治疗(ADT)的症状和影响”(SIADT-PC),评估激素治疗相关症状及其对晚期前列腺癌男性的影响.
    方法:对患有前列腺癌的成年男性进行概念启发(CE)访谈,以评估他们的ADT经历。根据提到的关键症状和影响概念,制定了初步的PRO措施。在对前列腺癌男性的认知汇报(CD)访谈中进一步评估了该草案。参与者审查了项目,响应选项,和召回期。使用访谈数据进行了基于项目的初始心理测量分析。问卷草案是在参与者反馈的基础上修订的,定量心理测量结果,并咨询临床专家。
    结果:总共对21名参与者进行了访谈(CE概念启发,n=12;CD认知汇报,n=17;n=8完成两者)。参与者平均年龄(SD)为59.7(8.7)岁,白人占76.2%。从头SIADT-PC测量包括27个项目:11个症状(例如,疲劳,潮热,和勃起功能障碍),2长期症状(例如,体重增加),10个影响(例如,对身体活动和人际关系的影响),和4与给药模式相关(即,注射部位反应)。项目用5分口头评定量表进行评估,带有捕获频率或严重性的答案选择。
    结论:一旦完全验证,这种从头测量可用于临床研究和临床实践,以评估激素治疗相关的症状和影响,使医生能够确定及时和适当的干预措施。
    BACKGROUND: This qualitative research study was conducted to develop a novel, comprehensive, patient-reported outcome measure (PRO), the \"Symptoms and Impacts of Androgen Deprivation Therapy (ADT) for Prostate Cancer\" (SIADT-PC), assessing hormonal therapy-related symptoms and their impacts on men with advanced prostate cancer.
    METHODS: Concept elicitation (CE) interviews were conducted among adult men with prostate cancer to evaluate their experiences with ADT. Based on key symptom and impact concepts mentioned, an initial PRO measure was developed. The draft measure was further assessed in cognitive debriefing (CD) interviews with men with prostate cancer, in which participants reviewed items, response options, and recall periods. Initial item-based psychometric analyses were conducted using interview data. The draft questionnaire was revised on the basis of participant feedback, quantitative psychometric results, and consultation with clinical experts.
    RESULTS: A total of 21 participants were interviewed (CE concept elicitation, n = 12; CD cognitive debriefing, n = 17; n = 8 completed both). Mean participant age (SD) was 59.7 (8.7) years and 76.2% were white. The de novo SIADT-PC measure consists of 27 items: 11 symptoms (e.g., fatigue, hot flashes, and erectile dysfunction), 2 long-term symptoms (e.g., weight gain), 10 impacts (e.g., impacts on physical activities and relationships), and 4 related to mode of administration (i.e., injection-site reactions). Items were assessed with a 5-point verbal rating scale, with answer choices that capture frequency or severity.
    CONCLUSIONS: Once fully validated, this de novo measure may be used in clinical studies and clinical practice to assess hormone therapy-related symptoms and impacts, enabling physicians to identify timely and appropriate interventions.

    就患者预后而言,关于前列腺癌(PCa)最有效的主要治疗方法存在争议,如手术或放射治疗(RT)。这项研究评估了前列腺癌根治术(RP)和RT治疗PCa的比较疗效和长期预后。对相关数据库进行了全面的文献综述,专注于2019年以来发表的学术和临床研究。纳入标准包括随机对照试验(RCT)和其他观察性研究,比较接受手术和RT治疗的患者的生存结果。我们遵循系统评价和荟萃分析(PRISMA)指南的首选报告项目,以提供数据的概述。我们根据纳入标准选择了19项研究。在总共19项研究中,12主张RP作为改善PCa患者生存结果的首选治疗方法。我们的综合结果显示,接受RT治疗的患者的前列腺癌特异性死亡率(PCSM)较低。分析的总效应大小计算为Z=1.19(p值=0.23)。研究中的异质性如下:Tau2=0.09,Chi2=20.25,df=4,I2=80%。此外,结果显示,接受前列腺切除术的患者的总生存期(OS)更高.发现分析的组合效应为:HR=0.97(0.93,1.01)。总效应计算为Z=1.33(p值=0.18)。发现异质性为Tau2=0.00,Chi2=1.33,df=2,I2=0%。然而,总死亡率(OM)与治疗方式无关.RT是PCa治疗的首选策略,因为它平衡了疗效和长期结果。临床决策应考虑患者的个体特征,未来的研究应深入研究特定的亚群和长期结果,以进一步完善治疗指南。
    There is controversy regarding the most effective primary treatment of choice for prostate cancer (PCa) in terms of patient outcomes, such as surgery or radiotherapy (RT). This study evaluated the comparative efficacy and long-term outcomes of radical prostatectomy (RP) and RT for PCa treatment. A thorough literature review of relevant databases was conducted, focusing on academic and clinical studies published from 2019 onwards. The inclusion criteria included randomized controlled trials (RCTs) and other observational studies comparing survival outcomes in patients treated with surgery and RT. We followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines to provide an overview of the data. We selected 19 studies based on the inclusion criteria. Of the total 19 studies, 12 advocated RP as the preferred treatment to improve survival outcomes in patients with PCa. The results of our synthesis showed that prostate cancer-specific mortality (PCSM) was lower in patients treated with RT. The total effect size for the analysis was calculated as Z=1.19 (p-value=0.23). The heterogeneity in the studies was as follows: Tau2=0.09, Chi2=20.25, df=4, I2=80%. Moreover, overall survival (OS) was shown to be higher in patients who underwent prostatectomy. The combined effect for the analysis was found to be: HR=0.97 (0.93, 1.01). The total effect was calculated as Z=1.33 (p-value= 0.18). The heterogeneity was found to be Tau2=0.00, Chi2=1.33, df=2, and I2=0%. However, overall mortality (OM) was shown to be independent of the treatment modality. RT is the preferred strategy for PCa treatment, as it balances efficacy and long-term outcomes. Clinical decision-making should consider individual patient characteristics and future research should delve into specific subpopulations and long-term outcomes to further refine the treatment guidelines.

    背景:前列腺癌的早期诊断是实现治愈的关键,其适当的管理导致良好的预后。在加纳,大部分患者患有晚期疾病,这些患者的异常表现会导致诊断延迟,从而使结果恶化。
    方法:我们介绍了三名非洲男性晚期前列腺癌患者,他们的诊断延迟。第一个病人,一名64岁男性出现2年腹水,体重减轻,没有下尿路症状,第二个,一名69岁的终末期肾衰竭患者持续6个月,正在接受透析,第三种情况,一名87岁男子出现慢性咳嗽和下尿路症状后,接受了肺结核治疗。所有患者最终都获得了升高的前列腺特异性抗原。进一步的调查,包括前列腺活检,病例1的腹骨盆CT扫描,腹骨盆超声,病例2的前列腺活检和血液尿素和电解质,前列腺活检,胸部和腰骶部诊断为转移性前列腺癌,所有患者均接受雄激素剥夺治疗。第二名患者接受了额外的放射治疗。
    结论:缺乏对前列腺癌症状(包括异常症状)的了解,可能导致延迟诊断,特别是在世界范围内大量患者患有晚期疾病的地区。
    BACKGROUND: Early diagnosis of prostate cancer is key to achieving a cure and its proper management leads to a good prognosis. In Ghana a large percentage of patients present with advanced disease and unusual presentations in these patients result in greater delay in the diagnosis thus worsening the outcomes.
    METHODS: We present three African males with advanced prostate cancer who had delayed diagnosis. The first patient, a 64 year old male presented with ascites of 2 years duration with weight loss and no lower urinary tract symptoms, the second, a 69 year old man with end stage renal failure of 6 months duration and was receiving dialysis, the third case, an 87 year old man was managed for pulmonary tuberculosis after he presented with chronic cough and lower urinary tract symptoms. All patients eventually had a prostate specific antigen done which were elevated. Further investigations including prostate biopsies, abdominopelvic CT scans for case 1, abdominopelvic ultrasound, prostate biopsies and blood urea and electrolytes for case 2, prostate biopsies, chest and lumbosacral showed a diagnosis of metastatic prostate carcinoma, and all patients were managed with androgen deprivation. The second patient received additional radiotherapy.
    CONCLUSIONS: A lack of knowledge of prostate cancer symptoms including unusual symptoms, can result in delayed diagnosis especially in regions of the world where a large number of patients present with advanced disease.

    转移相关蛋白1/蛋白激酶B(MTA1/AKT)信号通路已被证明在促进前列腺肿瘤生长方面具有协同作用。植物多酚的针对性拦截策略,特别是二苯乙烯,对MTA1介导的前列腺癌进展显示出巨大的希望。在这项研究中,我们在磷酸酶和张力蛋白同源物(Pten)缺失(R26MTA1;Ptenf/f)和PC3M前列腺癌细胞的背景下,采用了MTA1过表达的前列腺特异性转基因小鼠模型,该模型概括了晚期前列腺癌的分子通路改变.机械上,在培养的PC3M细胞中,gnetinC(二聚体白藜芦醇)对MTA1的敲除或药理学抑制导致哺乳动物雷帕霉素靶蛋白(mTOR)信号显着失活。在体内,小鼠耐受每天腹膜内治疗gnetinC(7mg/kgbw)12周,没有任何毒性迹象。在患有晚期前列腺癌的小鼠中,用gnetinC处理显著降低细胞增殖和血管生成并促进细胞凋亡。Further,除了降低前列腺上皮细胞中的MTA1水平,gnetinC显着降低前列腺组织中的mTOR信号活性,包括mTOR靶蛋白的活性:p70核糖体蛋白S6激酶(S6K)和真核翻译起始因子4E(elF4E)结合蛋白1(4EBP1)。总的来说,这些发现确立了gnetinC作为一种新的天然化合物,对MTA1/AKT/mTOR激活的前列腺癌具有抗癌特性,具有作为单一疗法的潜力,并可能作为未来临床批准的mTOR途径抑制剂的辅助药物。
    The metastasis-associated protein 1/protein kinase B (MTA1/AKT) signaling pathway has been shown to cooperate in promoting prostate tumor growth. Targeted interception strategies by plant-based polyphenols, specifically stilbenes, have shown great promise against MTA1-mediated prostate cancer progression. In this study, we employed a prostate-specific transgenic mouse model with MTA1 overexpression on the background of phosphatase and tensin homolog (Pten) null (R26MTA1; Ptenf/f) and PC3M prostate cancer cells which recapitulate altered molecular pathways in advanced prostate cancer. Mechanistically, the MTA1 knockdown or pharmacological inhibition of MTA1 by gnetin C (dimer resveratrol) in cultured PC3M cells resulted in the marked inactivation of mammalian target of rapamycin (mTOR) signaling. In vivo, mice tolerated a daily intraperitoneal treatment of gnetin C (7 mg/kg bw) for 12 weeks without any sign of toxicity. Treatment with gnetin C markedly reduced cell proliferation and angiogenesis and promoted apoptosis in mice with advanced prostate cancer. Further, in addition to decreasing MTA1 levels in prostate epithelial cells, gnetin C significantly reduced mTOR signaling activity in prostate tissues, including the activity of mTOR-target proteins: p70 ribosomal protein S6 kinase (S6K) and eukaryotic translational initiation factor 4E (elF4E)-binding protein 1 (4EBP1). Collectively, these findings established gnetin C as a new natural compound with anticancer properties against MTA1/AKT/mTOR-activated prostate cancer, with potential as monotherapy and as a possible adjunct to clinically approved mTOR pathway inhibitors in the future.

    目的:本研究旨在调查前列腺癌患者对雄激素剥夺治疗(ADT)的选择以及影响其ADT偏好的可能因素。
    方法:这是一项单中心横断面研究,调查ADT的使用和偏好。连续接受可注射黄体生成素释放激素(LHRH)激动剂或拮抗剂的前列腺癌患者从三级学术医院的前列腺癌诊所招募。接受双侧睾丸切除术的患者或不同意该研究的患者被排除。疾病特征,记录治疗信息和患者背景.调查收集了与他们改变ADT方案有关的信息,对药物使用的偏好(给药途径和频率)及其原因。设计了一组假设的三种药物配方。关于患者偏好的问题和问卷格式中提出的促成原因。
    结果:100名患者完成了调查。大多数患者开始注射更频繁(3个月,54%;1个月,38%),并在调查时切换为6个月注射(89%)。变化的主要原因是医疗保健意见(72%)和治疗频率较低(51%)。ADT的三种选择(每日口服,提供了1个月和6个月的注射),具有相同的功效和副作用:61%的首选6个月的注射,1%的人首选每月一次注射,38%的人首选口服方案。当患者在1个月注射或每日口服药物中被告知心血管副作用较低时,患者偏好为56%(6个月),6%(每月一次),39%(口服)。多重用药(超过5种常规药物)的患者更倾向于选择注射(p=0.025)。患者年龄,教育背景,就业状况,未发现婚姻状况和疾病状况是影响患者偏好的统计学显著因素.
    结论:尽管心血管风险更大,但6个月的ADT注射是首选的ADT。在每月或每天口服LHRH拮抗剂中,更多的患者更喜欢口服。便利因素受到高度重视。
    OBJECTIVE: 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.
    CONCLUSIONS: 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.

    本研究的目的是评估帕莫酸曲普瑞林治疗期间睾酮最低点是否低,促黄体激素释放激素(LHRH)激动剂,通过对临床试验数据的回顾性分析,与晚期前列腺癌患者的临床结局改善相关.
    数据来自三个前瞻性,曲普瑞林单药治疗晚期前列腺癌患者(包括NCT00751790)的9-12个月III期研究。评估的血清睾酮浓度抑制目标<0.35nmol/L(<10ng/dl),<0.7nmol/L(<20ng/dl),<1.7nmol/L(<50ng/dl)和≥1.7nmol/L通过Kaplan-Meier分析评估睾酮抑制组的总生存期(OS)和疾病特异性生存期(DSS),用对数秩检验。主要分析的时间范围为第1-518天(中位OS随访254天[范围,29-518天]),敏感性分析为第1-262天。补充分析结合≥0.7-至<1.7-nmol/L和≥1.7-nmol/L组。
    样本量包括592名患者(大多数接受曲普瑞林单药治疗;4例报告伴随雄激素受体轴靶向治疗)。<0.35,≥0.35至<0.7,≥0.7至<1.7和≥1.7nmol/L的最低点睾丸激素达到96%,3.2%,0.34%和0.17%的患者,分别。随着最低点睾酮水平的降低,观察到更好的OS(p<0.001),并且在敏感性/补充分析后仍然存在(所有p<0.001)。在主要分析中,DSS与最低点睾丸激素水平降低的差异无统计学意义。敏感性/补充分析显示,随着最低点睾酮水平的降低,DSS更好(第1-262天,p=0.01;组合组第1-518天,p=0.03;组合组第1-262天,p=0.005)。
    在晚期前列腺癌患者中,LHRH激动剂曲普瑞林治疗期间所达到的最低点睾酮与OS和DSS改善相关。
    UNASSIGNED: The objective of the study is to evaluate whether low nadir testosterone during treatment with triptorelin pamoate, a luteinising hormone-releasing hormone (LHRH) agonist, is associated with improved clinical outcomes in patients with advanced prostate cancer using a retrospective analysis of clinical trial data.
    UNASSIGNED: Data were pooled from three prospective, 9-12-month Phase III studies of triptorelin monotherapy in patients with advanced prostate cancer (including NCT00751790). The serum testosterone concentration suppression targets evaluated were <0.35 nmol/L (<10 ng/dl), <0.7 nmol/L (<20 ng/dl), <1.7 nmol/L (<50 ng/dl) and ≥1.7 nmol/L. Overall survival (OS) and disease-specific survival (DSS) by testosterone suppression group were assessed by Kaplan-Meier analysis, with log-rank test. The time frame for the primary analysis was Days 1-518 (median OS follow-up 254 days [range, 29-518 days]) and for the sensitivity analyses was Days 1-262. Supplementary analyses combined the ≥0.7- to <1.7-nmol/L and ≥1.7-nmol/L groups.
    UNASSIGNED: The sample size comprised 592 patients (most received triptorelin monotherapy; four reported concomitant androgen receptor-axis-targeted therapy). Nadir testosterones of <0.35, ≥0.35 to <0.7, ≥0.7 to <1.7 and ≥1.7 nmol/L were achieved by 96%, 3.2%, 0.34% and 0.17% of patients, respectively. Better OS with decreasing level of nadir testosterone was observed (p < 0.001) and this persisted after sensitivity/supplemental analyses (all p < 0.001). Differences in DSS with decreasing levels of nadir testosterone were not statistically significant in the primary analysis. Sensitivity/supplemental analysis showed better DSS with decreasing level of nadir testosterone (Days 1-262, p = 0.01; combined groups Days 1-518, p = 0.03; combined groups Days 1-262, p = 0.005).
    UNASSIGNED: Low nadir testosterone achieved during treatment with the LHRH agonist triptorelin was associated with improved OS and DSS in patients with advanced prostate cancer.

    背景:晚期前列腺癌(PC)的特征是对雄激素剥夺疗法和化疗不敏感,导致大多数患者的预后不佳。因此,先进的PC迫切需要新的治疗策略。越来越多的证据表明拼接失调是高级PC的标志。此外,对剪接过程的药物抑制正在成为这种疾病的一种有希望的选择.
    方法:通过使用代表性的雄激素不敏感的PC细胞系(22Rv1),我们已经研究了由三种剪接靶向药物产生的细胞毒性效应的全基因组转录组效应:帕拉地烯醇内酯B,indisulam和THZ531.进行生物信息学分析以揭示这些处理对转录和剪接调节的敏感性的基因结构特征。通过基因本体论分析注释了通过这些处理改变的生物学途径,并通过细胞模型中的功能实验进行了验证。
    结果:尽管对晚期PC细胞产生类似的细胞毒作用,帕地烯醇内酯B,indisulam和THZ531调节特定的转录和剪接特征。药物敏感性与独特的基因结构特征有关,受调控的外显子和内含子中的表达水平和顺式作用序列元件。重要的是,我们鉴定了药物诱导的剪接改变对细胞存活有影响的PC相关基因(即EZH2,MDM4)。此外,计算分析揭示了剪接靶向药物对内含子保留的广泛影响,与前mRNA3'端加工相关的基因富集(即CSTF3、PCF11)。连贯,高级PC细胞对裂解和聚腺苷酸化复合物的特异性抑制剂表现出高度敏感性,这增强了已经用于这种癌症的化疗药物的效果。
    结论:我们的研究发现内含子保留是高级PC的可操作漏洞,可用于改善这种目前无法治愈的疾病的治疗管理。
    BACKGROUND: Advanced prostate cancer (PC) is characterized by insensitivity to androgen deprivation therapy and chemotherapy, resulting in poor outcome for most patients. Thus, advanced PC urgently needs novel therapeutic strategies. Mounting evidence points to splicing dysregulation as a hallmark of advanced PC. Moreover, pharmacologic inhibition of the splicing process is emerging as a promising option for this disease.
    METHODS: By using a representative androgen-insensitive PC cell line (22Rv1), we have investigated the genome-wide transcriptomic effects underlying the cytotoxic effects exerted by three splicing-targeting drugs: Pladienolide B, indisulam and THZ531. Bioinformatic analyses were performed to uncover the gene structural features underlying sensitivity to transcriptional and splicing regulation by these treatments. Biological pathways altered by these treatments were annotated by gene ontology analyses and validated by functional experiments in cell models.
    RESULTS: Although eliciting similar cytotoxic effects on advanced PC cells, Pladienolide B, indisulam and THZ531 modulate specific transcriptional and splicing signatures. Drug sensitivity is associated with distinct gene structural features, expression levels and cis-acting sequence elements in the regulated exons and introns. Importantly, we identified PC-relevant genes (i.e. EZH2, MDM4) whose drug-induced splicing alteration exerts an impact on cell survival. Moreover, computational analyses uncovered a widespread impact of splicing-targeting drugs on intron retention, with enrichment in genes implicated in pre-mRNA 3\'-end processing (i.e. CSTF3, PCF11). Coherently, advanced PC cells displayed high sensitivity to a specific inhibitor of the cleavage and polyadenylation complex, which enhances the effects of chemotherapeutic drugs that are already in use for this cancer.
    CONCLUSIONS: Our study uncovers intron retention as an actionable vulnerability for advanced PC, which may be exploited to improve therapeutic management of this currently incurable disease.

    前列腺癌(PC)具有严重的公共卫生影响,由于人口老龄化,其发病率正在上升。在东南亚(SEA)指导PC管理的证据和共识有限。我们提供了SEA中用于高级PC护理的临床实践模式的实际数据。
    使用纸质调查来确定临床实践模式并在小组成员之间达成共识。调查包括小组成员的人口统计数据,使用临床指南,SEA高级PC管理中的临床实践模式。
    大多数小组成员(81%)认为前列腺特异性抗原(PSA)是早期PC诊断和风险分层的最有效测试。近44%的小组成员同意前列腺特异性膜抗原正电子发射断层扫描-计算机断层扫描成像用于PC诊断和分期信息有助于局部和全身治疗决策。大多数小组首选醋酸阿比特龙(67%)或多西他赛(44%)作为有症状的mCRPC患者的一线治疗。醋酸阿比特龙(50%)优先于多西他赛作为转移性去势敏感性前列腺癌患者的一线治疗。然而,专家组不支持在非转移性去势耐药前列腺癌(nmCRPC)患者中使用醋酸阿比特龙.阿帕鲁胺(75%)是nmCRPC患者的首选治疗选择。现代治疗和技术的成本和可用性是影响治疗决策的重要因素。所有小组成员都支持使用批准的疗法的通用版本。
    调查结果反映了东南亚国家先进PC的实际管理情况。这些发现可用于指导当地的临床实践,并突出现代医疗保健的财务挑战。
    UNASSIGNED: Prostate cancer (PC) has a serious public health impact, and its incidence is rising due to the aging population. There is limited evidence and consensus to guide the management of PC in Southeast Asia (SEA). We present real-world data on clinical practice patterns in SEA for advanced PC care.
    UNASSIGNED: A paper-based survey was used to identify clinical practice patterns and obtain consensus among the panelists. The survey included the demographics of the panelists, the use of clinical guidelines, and clinical practice patterns in the management of advanced PC in SEA.
    UNASSIGNED: Most panelists (81%) voted prostate-specific antigen (PSA) as the most effective test for early PC diagnosis and risk stratification. Nearly 44% of panelists agreed that prostate-specific membrane antigen positron emission tomography-computed tomography imaging for PC diagnostic and staging information aids local and systemic therapy decisions. The majority of the panel preferred abiraterone acetate (67%) or docetaxel (44%) as first-line therapy for symptomatic mCRPC patients. Abiraterone acetate (50%) is preferred over docetaxel as a first-line treatment in metastatic castration-sensitive prostate cancer patients with high-volume disease. However, the panel did not support the use of abiraterone acetate in non-metastatic castration-resistant prostate cancer (nmCRPC) patients. Apalutamide (75%) is the preferred treatment option for patients with nmCRPC. The cost and availability of modern treatments and technologies are important factors influencing therapeutic decisions. All panelists supported the use of generic versions of approved therapies.
    UNASSIGNED: The survey results reflect real-world management of advanced PC in a SEA country. These findings could be used to guide local clinical practices and highlight the financial challenges of modern healthcare.

    用前列腺特异性抗原(PSA)筛查前列腺癌可能导致不必要的活检和过度诊断。或者,PSA密度(PSAD)计算可能有助于支持活检决策;然而,其有用性的证据并不具体。
    通过系统和MRI靶向活检评估PSAD对临床上显着的前列腺癌检测的预测价值。
    这项前瞻性研究是在利雅得的两家三级医院进行的,沙特阿拉伯,2018年12月至2021年11月。怀疑前列腺癌的患者接受多参数MRI检查,对于那些有积极发现的人来说,我们进行了系统性和靶向性活检.基于组织病理学定义的ISUP等级或Gleason评分对临床上不显著和显著的前列腺癌病例进行分类。使用MRI确定的前列腺体积测量PSAD,并分为≤0.15、0.16-0.20和>0.20ng/ml2亚组。
    对284例患者进行了系统和靶向活检。与系统活检相比,PSAD在MRI靶向活检中的判别能力更高(AUC:0.77vs.0.73)。在靶向活检中检测到最高的敏感性(97%)和特异性(87%)为0.07ng/ml2。超过一半的临床显著病例在>0.2ng/ml2PSAD类别中检测到(系统性:52.4%;靶向:51.1%)。CHAID方法学发现,PSAD>0.15ng/ml2的患者患有临床意义的癌症(CSC)的概率是PSAD≤0.15ng/ml2的患者的三倍以上(64%vs.20.2%)。按年龄考虑,在PSAD≤0.15ng/ml2亚组中,≥60岁患者的CSC检出率百分比从20.2%上升至24.6%.
    PSAD对预测有临床意义的前列腺癌具有良好的判别力。应采用0.07ng/ml2的截止值,但应谨慎解释,并考虑其他参数,如年龄。
    UNASSIGNED: Prostate cancer screening with prostate-specific antigen (PSA) can result in unnecessary biopsies and overdiagnosis. Alternately, PSA density (PSAD) calculation may help support biopsy decisions; however, evidence of its usefulness is not concrete.
    UNASSIGNED: To evaluate the predictive value of PSAD for clinically significant prostate cancer detection by systematic and MRI-targeted biopsies.
    UNASSIGNED: This prospective study was conducted at two tertiary hospitals in Riyadh, Saudi Arabia, between December 2018 and November 2021. Patients suspected of prostate cancer were subjected to multi-parametric MRI, and for those with positive findings, systematic and targeted biopsies were performed. Clinically non-significant and significant prostate cancer cases were classified based on histopathology-defined ISUP grade or Gleason score. The PSAD was measured using the prostate volume determined by the MRI and categorized into ≤0.15, 0.16-0.20, and >0.20 ng/ml2 subgroups.
    UNASSIGNED: Systematic and targeted biopsies were carried out for 284 patients. The discriminant ability of PSAD is higher in MRI-targeted biopsy compared with systematic biopsy (AUC: 0.77 vs. 0.73). The highest sensitivity (97%) and specificity (87%) were detected at 0.07 ng/ml2 in targeted biopsy. More than half of the clinically significant cases were detected in the >0.2 ng/ml2 PSAD category (systematic: 52.4%; targeted: 51.1%). The CHAID methodology found that the probability of having clinically significant cancer (CSC) in patients with PSAD >0.15 ng/ml2 was more than threefold than that in patients with PSAD ≤0.15 ng/ml2 (64% vs. 20.2%). When considered by age, in PSAD ≤0.15 ng/ml2 subgroup, the percentage of CSC detection rate increased from 20.2% to 24.6% in patients aged ≥60 years.
    UNASSIGNED: PSAD has good discriminant power for predicting clinically significant prostate cancer. A cutoff of 0.07 ng/ml2 should be adopted, but should be interpreted with caution and by considering other parameters such as age.
