Prostate specific antigen

前列腺特异性抗原
  • 文章类型: Journal Article
    Purpose: Prostate cancer screening is a controversial topic. We examined trends in Prostate Specific Antigen (PSA) testing in an underserved population before and after the United States Preventative Services Task Force (USPSTF) recommendation against screening. Methods: Data were collected on all PSA and cholesterol screening tests from 2008 to 2014. We examined the trend of these tests and prostate biopsies while comparing this data to lipid panel data to adjust for changes in patient population. Results: A decrease in PSA screening was observed from 2010 through 2014, with the greatest decline in 2012. The age group most affected was patients aged 55-69 years. The amount of prostate biopsies during this period decreased as well. Conclusions: Decreased rates of PSA screening were observed in our urban hospital population that preceded the publication of the USPSTF guidelines. The incidence of prostate biopsies decreased in this timeframe. It now remains to be demonstrated whether decreased PSA screening rates impact the diagnosis of and ultimately the survival from prostate cancer.

    目的:本指南的目的是为根治性前列腺切除术后放疗作为辅助或挽救治疗提供临床框架。
    方法:使用PubMed®进行系统的文献综述,Embase,和Cochrane数据库用于确定与前列腺切除术后放疗使用相关的同行评审出版物.审查产生了294篇文章;这些出版物被用来创建基于证据的指南声明。当证据不足时,将提供额外的指导作为临床原则。
    结果:为患者提供咨询指南声明,放疗在辅助和抢救环境中的使用,定义生化复发,并进行重新评估。
    结论:医师应为前列腺切除术中出现不良病理结果的患者提供辅助放疗(即,精囊侵入,手术切缘阳性,前列腺外延伸),并且应为前列腺特异性抗原或前列腺切除术后局部复发的患者提供挽救性放疗,这些患者没有远处转移性疾病的证据。放射治疗的提议应在对放射治疗可能的短期和长期副作用以及预防复发的潜在益处进行深思熟虑的讨论的背景下进行。放疗的决定应由患者和多学科治疗小组在充分考虑患者病史的情况下做出。值,preferences,生活质量,和功能状态。请访问ASTRO和AUA网站(http://www.redjournal.org/webfiles/images/journals/rob/RAP%20Guideline.pdf和http://www.auanet.org/education/guidelines/radiation-after-prostatomy.cfm)以完整查看本指南,包括完整的文献综述。
    OBJECTIVE: The purpose of this guideline is to provide a clinical framework for the use of radiotherapy after radical prostatectomy as adjuvant or salvage therapy.
    METHODS: A systematic literature review using the PubMed®, Embase, and Cochrane databases was conducted to identify peer-reviewed publications relevant to the use of radiotherapy after prostatectomy. The review yielded 294 articles; these publications were used to create the evidence-based guideline statements. Additional guidance is provided as Clinical Principles when insufficient evidence existed.
    RESULTS: Guideline statements are provided for patient counseling, the use of radiotherapy in the adjuvant and salvage contexts, defining biochemical recurrence, and conducting a re-staging evaluation.
    CONCLUSIONS: Physicians should offer adjuvant radiotherapy to patients with adverse pathologic findings at prostatectomy (i.e., seminal vesicle invasion, positive surgical margins, extraprostatic extension) and should offer salvage radiotherapy to patients with prostatic specific antigen or local recurrence after prostatectomy in whom there is no evidence of distant metastatic disease. The offer of radiotherapy should be made in the context of a thoughtful discussion of possible short- and long-term side effects of radiotherapy as well as the potential benefits of preventing recurrence. The decision to administer radiotherapy should be made by the patient and the multi-disciplinary treatment team with full consideration of the patient\'s history, values, preferences, quality of life, and functional status. Please visit the ASTRO and AUA websites (http://www.redjournal.org/webfiles/images/journals/rob/RAP%20Guideline.pdf and http://www.auanet.org/education/guidelines/radiation-after-prostatectomy.cfm) to view this guideline in its entirety, including the full literature review.

    目的:本指南旨在基于现有的已发表数据,为去势抵抗性前列腺癌患者的治疗提供合理的依据。
    方法:使用对照词汇对已发表的文献进行系统综述和荟萃分析,并补充与前列腺癌和去势抵抗相关概念相关的关键词。搜索策略由参考图书馆员和方法学家制定和执行,以创建仅限于英语的证据报告,发表同行评议的文献。这篇综述产生了从1996年到2013年发表的303篇文章,这些文章被用来构成大多数指南声明。临床原则和专家意见用于缺乏足够的循证数据的指南陈述。
    结果:创建了指南声明,以告知临床医生适当使用观察,雄激素剥夺和抗雄激素治疗,雄激素合成抑制剂,免疫疗法,放射性核素治疗,全身化疗,姑息治疗和骨骼健康。这些是基于六个指标患者开发的,以代表临床实践中遇到的最常见情况。
    结论:由于FDA批准的用于转移性CRPC患者的治疗药物的显著增加,临床医生面临着多种治疗选择和这些药物的潜在排序的挑战,因此,使临床决策更加复杂。鉴于这一领域的快速发展性质,本指南应与近期的系统文献综述以及对个体患者治疗目标的理解结合使用.在所有情况下,在选择管理策略时,应考虑患者的偏好和个人目标。
    OBJECTIVE: This Guideline is intended to provide a rational basis for the management of patients with castration-resistant prostate cancer based on currently available published data.
    METHODS: A systematic review and meta-analysis of the published literature was conducted using controlled vocabulary supplemented with keywords relating to the relevant concepts of prostate cancer and castration resistance. The search strategy was developed and executed by reference librarians and methodologists to create an evidence report limited to English-language, published peer-reviewed literature. This review yielded 303 articles published from 1996 through 2013 that were used to form a majority of the guideline statements. Clinical Principles and Expert Opinions were used for guideline statements lacking sufficient evidence-based data.
    RESULTS: Guideline statements were created to inform clinicians on the appropriate use of observation, androgen-deprivation and antiandrogen therapy, androgen synthesis inhibitors, immunotherapy, radionuclide therapy, systemic chemotherapy, palliative care and bone health. These were based on six index patients developed to represent the most common scenarios encountered in clinical practice.
    CONCLUSIONS: As a direct result of the significant increase in FDA-approved therapeutic agents for use in patients with metastatic CRPC, clinicians are challenged with a multitude of treatment options and potential sequencing of these agents that, consequently, make clinical decision-making more complex. Given the rapidly evolving nature of this field, this guideline should be used in conjunction with recent systematic literature reviews and an understanding of the individual patient\'s treatment goals. In all cases, patients\' preferences and personal goals should be considered when choosing management strategies.

    目的:指南的目的是为泌尿科医生提供一个在无症状的平均风险男性中早期发现前列腺癌的框架。
    方法:进行了系统评价,并总结了来自300项研究的证据,这些研究涉及预定义的目标(前列腺癌发病率/死亡率,生活质量,诊断准确性和测试的危害)。除了证据的质量,小组考虑了在临床环境中表达的价值观和偏好(患者-医师二元),而不是从公共卫生角度出发.指南声明按年龄组(年龄<40岁;40至54岁;55至69岁;≥70岁)进行组织。
    结果:除了基于前列腺特异性抗原的前列腺癌筛查,对其他测试感兴趣的结局进行评估的证据很少.筛查益处的证据质量适中,对于55至69岁的男性来说,伤害的证据很高。对于这个年龄范围之外的男人,缺乏好处的证据,但筛查的危害,包括过度诊断和过度治疗,remains.模拟数据表明,筛选间隔两年或更长时间可能是优选的,以减少筛选的危害。
    结论:专家小组建议55至69岁男性共同决策,考虑基于PSA的筛查,利益可能大于危害的目标年龄组。在这个年龄范围之外,根据现有证据,不推荐将基于PSA的筛查作为常规筛查。
    OBJECTIVE: The guideline purpose is to provide the urologist with a framework for the early detection of prostate cancer in asymptomatic average risk men.
    METHODS: A systematic review was conducted and summarized evidence derived from over 300 studies that addressed the predefined outcomes of interest (prostate cancer incidence/mortality, quality of life, diagnostic accuracy and harms of testing). In addition to the quality of evidence, the panel considered values and preferences expressed in a clinical setting (patient-physician dyad) rather than having a public health perspective. Guideline statements were organized by age group in years (age <40; 40 to 54; 55 to 69; ≥ 70).
    RESULTS: Except prostate specific antigen-based prostate cancer screening, there was minimal evidence to assess the outcomes of interest for other tests. The quality of evidence for the benefits of screening was moderate, and evidence for harm was high for men age 55 to 69 years. For men outside this age range, evidence was lacking for benefit, but the harms of screening, including over diagnosis and overtreatment, remained. Modeled data suggested that a screening interval of two years or more may be preferred to reduce the harms of screening.
    CONCLUSIONS: The Panel recommended shared decision-making for men age 55 to 69 years considering PSA-based screening, a target age group for whom benefits may outweigh harms. Outside this age range, PSA-based screening as a routine could not be recommended based on the available evidence.
