    这项研究评估了奥地利使用低剂量计算机断层扫描(LDCT)进行肺癌筛查(LCS)计划的成本效益。使用具有集成马尔可夫模型的现有决策树来分析LCS的成本效益,而不是从终身范围内的医疗保健支付者角度进行筛查。使用荷兰-比利时肺癌筛查研究(Nederlands-LeuvensLongkankerScreeningsONderzoek,对50-74岁有吸烟史的无症状高危人群进行了模拟,尼尔森)筛查结果。用于评估成本效益的主要措施是增量成本效益比(ICER)。采用敏感性和情景分析来确定关键模型输入的不确定性。在50%的吸收率下,300,277名符合条件的个人将参加LCS计划,与没有筛查相比,获得了56,122个增量质量调整生命年(QALYs)和84,049个生命年,每QALY获得24,627欧元的ICER,每生命年节省16,444欧元。此外,LCS导致检测到25,893例其他早期肺癌,并避免了11,906例过早肺癌死亡。据估计,LCS将产生9.45亿欧元的额外筛查费用和3.86亿欧元的额外治疗费用。这些估计在敏感性分析中是稳健的。为高危人群实施年度LCS和LDCT,使用尼尔森筛查结果,在奥地利很划算,每个QALY的门槛为50,000欧元。
    This study assessed the cost-effectiveness of a lung cancer screening (LCS) program using low-dose computed tomography (LDCT) in Austria. An existing decision tree with an integrated Markov model was used to analyze the cost-effectiveness of LCS versus no screening from a healthcare payer perspective over a lifetime horizon. A simulation was conducted to model annual LCS for an asymptomatic high-risk population cohort aged 50-74 with a smoking history using the Dutch-Belgian Lung Cancer Screening Study (NEderlands-Leuvens Longkanker ScreeningsONderzoek, NELSON) screening outcomes. The principal measure utilized to assess cost-effectiveness was the incremental cost-effectiveness ratio (ICER). Sensitivity and scenario analyses were employed to determine uncertainties surrounding the key model inputs. At an uptake rate of 50%, 300,277 eligible individuals would participate in the LCS program, yielding 56,122 incremental quality-adjusted life years (QALYs) and 84,049 life years gained compared to no screening, with an ICER of EUR 24,627 per QALY gained or EUR 16,444 per life-year saved. Additionally, LCS led to the detection of 25,893 additional early-stage lung cancers and averted 11,906 premature lung cancer deaths. It was estimated that LCS would incur EUR 945 million additional screening costs and EUR 386 million additional treatment costs. These estimates were robust in sensitivity analyses. Implementation of annual LCS with LDCT for a high-risk population, using the NELSON screening outcomes, is cost-effective in Austria, at a threshold of EUR 50,000 per QALY.

    胰腺导管腺癌(PDA)是最具侵袭性的癌症之一。它的5年生存率很低,只有12%,部分原因是大多数病例在晚期被诊断,排除根治性手术切除。早期PDA具有明显更好的预后,因为治疗干预的潜力增加,使早期发现PDA对改善患者预后至关重要。我们研究了当前和不断发展的早期检测概念,筛选策略,高危人群的诊断率,争议,和标准护理成像的局限性。
    Pancreatic ductal adenocarcinoma (PDA) is one of the most aggressive cancers. It has a poor 5-year survival rate of 12%, partly because most cases are diagnosed at advanced stages, precluding curative surgical resection. Early-stage PDA has significantly better prognoses due to increased potential for curative interventions, making early detection of PDA critically important to improved patient outcomes. We examine current and evolving early detection concepts, screening strategies, diagnostic yields among high-risk individuals, controversies, and limitations of standard-of-care imaging.

    西班牙家族性胰腺癌注册中心(PANGENFAM)成立于2009年,旨在表征家族性胰腺癌(FPC)的基因型和表型。此外,我们为来自FPC和遗传性胰腺癌家族(一级亲属)的健康高危人群提供了胰腺导管腺癌(PDAC)的早期检测筛查计划.本文介绍了我们过去10年在高风险筛查方面的经验。通过肿瘤学和胃肠病学部门确定了遗传性和家族性胰腺癌家族。高危人群每年接受内窥镜超声(EUS)和磁共振(MRI)筛查,年龄比最年轻的患病家庭成员小40岁或10岁。结果:PANGENFAM招募了来自143个家庭的290人,包括52例PDAC病例和238例高危人群。所有符合筛查条件的高危人群都可以进入监测项目,目前有143人参加。在94名个体中检测到胰腺异常(中位年龄53岁(29-83),常见发现包括囊性病变和薄壁组织不均匀。影像学检查符合率为66%。在影像学检测到高度可疑的病变后,对4名高风险个体进行了手术干预。PANGENFAM是科学创新的宝贵资源,比如生物缓冲,临床和影像学数据可供分析。对于高危家庭,它可能提供早期诊断的潜力。需要与其他国家和国际注册管理机构合作,以增加我们对疾病生物学的了解,并标准化纳入和后续行动的标准,优化成本效益和功效。
    The Spanish Familial Pancreatic Cancer Registry (PANGENFAM) was established in 2009 and aims to characterize the genotype and phenotype of familial pancreatic cancer (FPC). Furthermore, an early detection screening program for pancreatic ductal adenocarcinoma (PDAC) is provided to healthy high-risk individuals from FPC and hereditary pancreatic cancer families (first-degree relatives). This article describes our experience over the last 10 years in high-risk screening. Hereditary and familial pancreatic cancer families were identified through the oncology and gastroenterology units. High-risk individuals underwent annual screening with endoscopic ultrasound (EUS) and magnetic resonance (MRI) from age 40 or 10 years younger than the youngest affected family member. Results: PANGENFAM has enrolled 290 individuals from 143 families, including 52 PDAC cases and 238 high-risk individuals. All high-risk individuals eligible for screening were offered to enter the surveillance program, with 143 currently participating. Pancreatic abnormalities were detected in 94 individuals (median age 53 years (29-83), with common findings including cystic lesions and inhomogeneous parenchyma. Imaging test concordance was 66%. Surgical intervention was performed in 4 high-risk individuals following highly suspicious lesions detected by imaging. PANGENFAM is a valuable resource for science innovation, such as biobanking, with clinical and imaging data available for analysis. For high-risk families, it may offer a potential for early diagnosis. Collaboration with other national and international registries is needed to increase our understanding of the disease biology and to standardize criteria for inclusion and follow-up, optimizing cost-effectiveness and efficacy.

    胰腺癌在普通人群中预后不良。然而,早期发现和治疗高危个体的疾病可以提高生存率,因为患有局部疾病的患者,尤其是病变小于10毫米的患者,5年生存率大大提高。为了通过MRI监测程序实现早期检测,需要优化成像。多年来在硬件和软件方面的MRI技术的进步使得能够在小尺寸和早期阶段可靠地检测胰腺癌。胰腺专用成像方案的标准化仍然缺乏。在这篇综述中,我们讨论了最先进的扫描技术,序列,减少伪影和成像策略,使病变的早期检测。此外,我们介绍了来自大量高危人群的小胰腺癌的影像学特征.MRI技术的改进,提高扫描质量和人工智能的使用可能会进一步改善筛查环境中胰腺癌的早期发现和预后。
    Pancreatic cancer has a dismal prognosis in the general population. However, early detection and treatment of disease in high-risk individuals can improve survival, as patients with localized disease and especially patients with lesions smaller than 10 mm show greatly improved 5-year survival rates. To achieve early detection through MRI surveillance programs, optimization of imaging is required. Advances in MRI technologies in both hardware and software over the years have enabled reliable detection of pancreatic cancer at a small size and early stage. Standardization of dedicated imaging protocols for the pancreas are still lacking. In this review we discuss state of the art scan techniques, sequences, reduction of artifacts and imaging strategies that enable early detection of lesions. Furthermore, we present the imaging features of small pancreatic cancers from a large cohort of high-risk individuals. Refinement of MRI techniques, increased scan quality and the use of artificial intelligence may further improve early detection and the prognosis of pancreatic cancer in a screening setting.

    胰腺导管腺癌(PDAC)是癌症相关死亡的主要原因,并与不良预后相关。这些癌症大多数是在晚期发现的,导致不良预后。这强调了小说的必要性,加强早期检测策略,以改善结果。虽然不推荐基于人群的筛查,因为PDAC的发病率相对较低,由于PDAC的发病率增加,建议对PDAC高危人群进行监测.然而,高危人群的胰腺癌监测结果尚未分类.在这次审查中,我们将解决PDAC高危人群的识别问题,讨论监视的目标和目标,概述监视计划是如何组织的,总结接受胰腺癌监测的高危个体的结果,并总结了对胰腺癌监测和新发展的未来观点。
    Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related deaths and is associated with a poor prognosis. The majority of these cancers are detected at a late stage, contributing to the bad prognosis. This underscores the need for novel, enhanced early detection strategies to improve the outcomes. While population-based screening is not recommended due to the relatively low incidence of PDAC, surveillance is recommended for individuals at high risk for PDAC due to their increased incidence of the disease. However, the outcomes of pancreatic cancer surveillance in high-risk individuals are not sorted out yet. In this review, we will address the identification of individuals at high risk for PDAC, discuss the objectives and targets of surveillance, outline how surveillance programs are organized, summarize the outcomes of high-risk individuals undergoing pancreatic cancer surveillance, and conclude with a future perspective on pancreatic cancer surveillance and novel developments.

    患有胰腺导管腺癌的高风险个体有资格在研究计划中进行监测。这些程序采用磁共振成像/磁共振胰胆管造影或内窥镜超声形式的周期性成像,以检测早期癌症或高级前体病变。这篇叙述性综述讨论了超声内镜在这些监测计划中的作用。它详细介绍了它的整体优势和局限性,产量,患者的负担,以及它与磁共振成像的比较。最后,建议何时以及如何将超声内镜纳入高危人群的监测中。
    Individuals at high risk of developing pancreatic ductal adenocarcinoma are eligible for surveillance within research programs. These programs employ periodic imaging in the form of magnetic resonance imaging/magnetic resonance cholangiopancreatography or endoscopic ultrasound for the detection of early cancer or high-grade precursor lesions. This narrative review discusses the role of endoscopic ultrasound within these surveillance programs. It details its overall strengths and limitations, yield, burden on patients, and how it compares to magnetic resonance imaging. Finally, recommendations are given when and how to incorporate endoscopic ultrasound in the surveillance of high-risk individuals.

    从结构和功能脑特征预测的脑年龄测量越来越多地用于了解脑完整性,障碍,和健康。虽然有大量文献显示患有酒精使用障碍(AUD)和有酒精使用障碍风险的个体的结构和功能大脑测量异常,很少有研究调查这些群体的大脑年龄。当前的研究检查了使用大脑形态特征预测的大脑年龄指标,例如皮质厚度和脑体积,在终生诊断为AUD的个体中,以及在具有多个受AUD影响的家庭中发展AUD的风险较高的个体中(即,较高的家族史密度(FHD)评分)。AUD数据集包括一组30名成年男性(平均年龄=41.25岁),终生诊断为AUD且目前戒断,以及一组30名男性对照(平均年龄=27.24岁),没有任何AUD史。根据他们的FHD评分分类的年轻人的第二个数据集包括一组40名具有AUD高FHD的个体(20名男性)(平均年龄=25.33岁)和一组31名具有低FHD的个体(18名男性)(平均年龄=25.47岁)。在XGBoost回归模型中,使用187个皮质厚度和脑体积的脑形态学特征来预测脑年龄;将偏差校正程序应用于预测的脑年龄。结果显示,AUD和高FHD个体均显示1.70和0.09年(1.08个月)的增加,分别,相对于实际年龄,他们的大脑年龄,提示AUD加速大脑老化和AUD风险。大脑年龄的增加与AUD和高FHD个体的执行功能的神经认知测试表现不佳有关,这表明大脑年龄也可以作为认知功能和大脑健康的代表。这些群体中关于脑老化的发现可能对预防和治疗AUD以及随之而来的认知能力下降具有重要意义。
    Brain age measures predicted from structural and functional brain features are increasingly being used to understand brain integrity, disorders, and health. While there is a vast literature showing aberrations in both structural and functional brain measures in individuals with and at risk for alcohol use disorder (AUD), few studies have investigated brain age in these groups. The current study examines brain age measures predicted using brain morphological features, such as cortical thickness and brain volume, in individuals with a lifetime diagnosis of AUD as well as in those at higher risk to develop AUD from families with multiple members affected with AUD (i.e., higher family history density (FHD) scores). The AUD dataset included a group of 30 adult males (mean age = 41.25 years) with a lifetime diagnosis of AUD and currently abstinent and a group of 30 male controls (mean age = 27.24 years) without any history of AUD. A second dataset of young adults who were categorized based on their FHD scores comprised a group of 40 individuals (20 males) with high FHD of AUD (mean age = 25.33 years) and a group of 31 individuals (18 males) with low FHD (mean age = 25.47 years). Brain age was predicted using 187 brain morphological features of cortical thickness and brain volume in an XGBoost regression model; a bias-correction procedure was applied to the predicted brain age. Results showed that both AUD and high FHD individuals showed an increase of 1.70 and 0.09 years (1.08 months), respectively, in their brain age relative to their chronological age, suggesting accelerated brain aging in AUD and risk for AUD. Increased brain age was associated with poor performance on neurocognitive tests of executive functioning in both AUD and high FHD individuals, indicating that brain age can also serve as a proxy for cognitive functioning and brain health. These findings on brain aging in these groups may have important implications for the prevention and treatment of AUD and ensuing cognitive decline.

    用于早期发现和治疗胰腺癌(PC)及其前体病变的筛查程序在全球范围内越来越多地实施,以降低疾病特异性致死率。鉴于这种疾病的患病率相对较低,这种方法的理想目标是丰富的人群,与普通人群相比,他们一生中罹患PC的风险明显更高。考虑到其家族中PC病例的大量聚集(即家族性胰腺癌)或富含与胰腺癌发生相关的致病变异(即突变携带者)的基因组景观。在意大利,2015年启动了一项针对PC高危人群的人口普查和监测的国家登记册,截至目前,该登记册登记了约1200名受试者.从这个角度来看,科学背景,多层次结构,概述了IRFARPC的演变,以及它的长期结果,未来的发展,和需要改进的地方。
    Screening programs for early detection and treatment of pancreatic cancer (PC) and its precursor lesions are increasingly implemented worldwide to reduce disease-specific lethality. Given the relatively low prevalence of the disease, the ideal target of such approaches is an enriched cohort of individuals harboring a lifetime risk of developing PC significantly higher compared to the general population, given either a substantial aggregation of PC cases in their family (i.e. familial pancreatic cancer) or a genomic landscape enriched with pathogenic variants associated with pancreatic carcinogenesis (i.e. mutation carriers). In Italy, a national registry for the census and surveillance of high-risk individuals for PC was launched in 2015, enrolling some 1200 subjects as of today. In this perspective, the scientific background, multi-level structure, and evolution of IRFARPC are outlined, as well as its long-term results, future developments, and areas for improvement.

    背景:基于人群的食管癌(EC)筛查试验和项目已经在中国进行了数十年;然而,不同地区采用了筛查策略,筛查概况尚不清楚.
    目的:我们进行了一项荟萃分析,以按阳性率,合规率,和内窥镜检查结果,旨在为EC筛查计划提供明确的证据和建议。
    方法:English(PubMed,Embase)和中文(中国国家知识基础设施,Wanfang)的语言数据库进行了系统搜索,以在2022年12月31日之前在中国人群中进行基于人群的EC筛查研究。使用随机效应模型通过标准方法进行荟萃分析。计算三组的合并患病率:采用通用内窥镜检查策略的高危地区,中国农村采用风险分层内镜筛查(RSES)策略,和RSES战略的中国城市。阳性病例包括严重发育不良的病变,原位癌,粘膜内癌,粘膜下癌,和浸润性癌。
    结果:中国农村高危人群的合并阳性率(44.12%)高于中国城市(23.11%)。我国农村内镜检查的达标率最高(52.40%),其次是高风险地区(50.11%),最低的是中国城市(23.67%)。阳性病例的合并检出率从高风险地区的1.03%(95%CI0.82%-1.30%)下降到中国农村的0.48%(95%CI0.25%-0.93%)和中国城市的0.12%(95%CI0.07%-0.21%)。低度上皮内瘤变(LGIN)的合并检出率也在同一顺序,在高风险地区最高(3.99%,95%CI2.78%-5.69%),其次是中国农村(2.55%,95%CI1.03%-6.19%)和中国城市(0.34%,95%CI0.14%-0.81%)。在男性中观察到阳性病例和LGIN的检出率高于女性和老年人。合并的早期检出率为81.90%(95%CI75.58%-86.88%),这与高风险地区的比率(82.09%)相似,在中国农村(80.76%),在中国城市(80.08%)。
    结论:在目前的筛查框架下,高危地区的筛查获益高于其他地区.为了促进电子商务筛查,减少目前中国筛查的不平等,应更多关注优化高危个体评估和监测管理策略,以提高内镜检查的依从性.

    Population-based esophageal cancer (EC) screening trials and programs have been conducted in China for decades; however, screening strategies have been adopted in different regions and screening profiles are unclear.
    We performed a meta-analysis to profile EC screening in China by positivity rate, compliance rate, and endoscopy findings, aiming to provide explicit evidence and recommendations for EC screening programs.
    English (PubMed, Embase) and Chinese (China National Knowledge Infrastructure, Wanfang) language databases were systematically searched for population-based EC screening studies in the Chinese population until December 31, 2022. A meta-analysis was performed by standard methodology using a random-effects model. Pooled prevalence rates were calculated for three groups: high-risk areas with a universal endoscopy strategy, rural China with a risk-stratified endoscopic screening (RSES) strategy, and urban China with an RSES strategy. Positive cases included lesions of severe dysplasia, carcinoma in situ, intramucosal carcinoma, submucosal carcinoma, and invasive carcinoma.
    The pooled positivity rate of the high-risk population was higher in rural China (44.12%) than in urban China (23.11%). The compliance rate of endoscopic examinations was the highest in rural China (52.40%), followed by high-risk areas (50.11%), and was the lowest in urban China (23.67%). The pooled detection rate of positive cases decreased from 1.03% (95% CI 0.82%-1.30%) in high-risk areas to 0.48% (95% CI 0.25%-0.93%) in rural China and 0.12% (95% CI 0.07%-0.21%) in urban China. The pooled detection rate of low-grade intraepithelial neoplasia (LGIN) was also in the same order, being the highest in high-risk areas (3.99%, 95% CI 2.78%-5.69%), followed by rural China (2.55%, 95% CI 1.03%-6.19%) and urban China (0.34%, 95% CI 0.14%-0.81%). Higher detection rates of positive cases and LGIN were observed among males than among females and at older ages. The pooled early detection rate was 81.90% (95% CI 75.58%-86.88%), which was similar to the rates in high-risk areas (82.09%), in rural China (80.76%), and in urban China (80.08%).
    Under the current screening framework, a higher screening benefit was observed in high-risk areas than in other regions. To promote EC screening and reduce the current inequality of screening in China, more focus should be given to optimizing strategies of high-risk individual assessment and surveillance management to improve compliance with endoscopic examination.
