    方法:这是1-1b/2阶段,开放标签,跨国公司,晚期/转移性黑色素瘤或NSCLC患者的多中心研究,其中≥1个可测量病变。
    方法:患者每4周给予sabatolimab800mg,每4周给予spartalizumab400mg,直至出现不可接受的毒性,疾病进展和/或治疗中断。
    方法:2期主要结果指标是总体反应率,次要目标包括安全性评估,耐受性,sabatolimab联合司他珠单抗的疗效和药代动力学。
    结果:33例患者(黑色素瘤n=16,非小细胞肺癌n=17)接受了sabatolimab联合司他珠单抗治疗。31(94%)经历≥1次不良事件(AE);15(46%)经历3/4级事件。NSCLC最常见的≥3级AE是贫血,呼吸困难和肺炎(每个n=2,12%);对于黑色素瘤患者,最常见的≥3级AE是身体健康恶化,低钾血症,低磷酸盐血症,病理性骨折和肿瘤浸润(每个n=1;6%)。1例(3%)患者因AE停止治疗。在3例黑色素瘤患者(19%)和6例NSCLC患者(35%)中发现疾病稳定。黑色素瘤和非小细胞肺癌患者的中位无进展生存期为1.8个月(90%CI1.7至1.9)和1.7个月(90%CI1.1至3.4),分别。疾病稳定的患者在基线时CD8,LAG3,程序性死亡配体1和抗T细胞免疫球蛋白和含粘蛋白结构域3的表达水平较高。sabatolimab的药代动力学特征与1期研究一致。
    结论:Sabatolimab联合司他珠单抗在抗程序性死亡-1/抗程序性死亡-配体-1治疗后进展的晚期/转移性黑色素瘤或NSCLC患者中具有良好的耐受性。观察到有限的抗肿瘤活性。sabatolimab给药的耐受性支持了在各种组合方案和一系列肿瘤类型中探索sabatolimab治疗的潜力。
    背景:NCT02608268。
    OBJECTIVE: This study evaluates the safety/efficacy of sabatolimab plus spartalizumab in patients with melanoma or non-small cell lung cancer (NSCLC).
    METHODS: This is a phase 1-1b/2, open-label, multinational, multicentre study of patients with advanced/metastatic melanoma or NSCLC with ≥1 measurable lesion.
    METHODS: Patients were given sabatolimab 800 mg every 4 weeks plus spartalizumab 400 mg every 4 weeks until unacceptable toxicity, disease progression and/or treatment discontinuation.
    METHODS: The phase 2 primary outcome measure was overall response rate and secondary objectives included evaluation of the safety, tolerability, efficacy and pharmacokinetics of sabatolimab in combination with spartalizumab.
    RESULTS: 33 patients (melanoma n=16, NSCLC n=17) received sabatolimab plus spartalizumab. 31 (94%) experienced ≥1 adverse event (AE); 15 (46%) experienced grade 3/4 events. The most frequent grade ≥3 AEs for NSCLC were anaemia, dyspnoea and pneumonia (each n=2, 12%); for patients with melanoma, the most frequent grade ≥3 AEs were physical health deterioration, hypokalaemia, hypophosphataemia, pathological fracture and tumour invasion (each n=1; 6%). One (3%) patient discontinued treatment due to AE. Stable disease was seen in three patients with melanoma (19%) and six patients with NSCLC (35%). Median progression-free survival was 1.8 (90% CI 1.7 to 1.9) and 1.7 (90% CI 1.1 to 3.4) months for patients with melanoma and NSCLC, respectively. Patients with stable disease had higher expression levels of CD8, LAG3, programmed death-ligand 1 and anti-T-cell immunoglobulin and mucin-domain containing-3 at baseline. The pharmacokinetics profile of sabatolimab was consistent with the phase 1 study.
    CONCLUSIONS: Sabatolimab plus spartalizumab was well tolerated in patients with advanced/metastatic melanoma or NSCLC who had progressed following antiprogrammed death-1/antiprogrammed death-ligand 1 treatment. Limited antitumour activity was observed. The tolerability of sabatolimab administration supports the potential to explore treatment with sabatolimab in various combination regimens and across a spectrum of tumour types.

  • 文章类型: Clinical Trial Protocol
    背景:肺癌是全球癌症死亡的最常见原因。2022年,英国国家筛查委员会建议实施国家针对性肺癌筛查计划。旨在提高早期诊断和生存率。国际上的研究和服务一致观察到筛查吸收方面的社会经济和与吸烟相关的不平等。路径导航(PN)是一个过程,通过这个过程,一个训练有素的路径导航员引导人们克服障碍,获得医疗服务,包括筛查。这项巢式随机对照试验旨在确定,作为约克郡肺部筛查试验(YLST)的一部分,与以前的无反应者人群中通常的书面邀请相比,PN干预是否会导致更多的人参与肺癌筛查。
    方法:一项嵌套在YLST内的双臂随机对照试验和过程评估。年龄在55-80岁(含55岁)之间的参与者尚未对以前的邮政邀请做出回应,他们将在2023年3月至2024年10月之间按家庭随机接受PN或常规护理(进一步的邮政邀请,以联系筛查服务进行肺部健康检查)。PN干预包括邮政预约通知和预先安排的电话预约,在此期间,路径导航员给参与者打电话,遵循四步协议,介绍报价并进行初步风险评估。如果符合条件,参与者被邀请预订低剂量CT(LDCT)肺癌筛查扫描.所有途径导航员都接受行为心理学家关于动机面试和沟通技巧的培训,以引发筛查出勤的障碍并提供解决方案。
    方法:接受肺癌风险初步电话评估的人数。正在进行LDCT筛查扫描的号码。次要结果包括人口统计,接受电话风险评估的患者的临床和风险参数;电话风险评估后符合筛查条件的人数;诊断的筛查癌症数量;成本和混合方法过程评估。描述性分析将用于呈现数字,工艺评价的比例和定量成分。组间差异的主要比较将使用逻辑回归进行。应用主题分析将用于在基于COM-B框架的概念框架内解释定性数据。还将对PN干预措施进行健康经济分析。
    背景:在保密咨询小组审查后,该研究得到了大曼彻斯特西部研究伦理委员会(18-NW-0012)和健康研究管理局的批准。结果将通过同行评审的科学期刊分享,会议演示文稿和YLST网站。
    背景:ISRCTN42704678和NCT03750110。
    BACKGROUND: Lung cancer is the most common cause of cancer death globally. In 2022 the UK National Screening Committee recommended the implementation of a national targeted lung cancer screening programme, aiming to improve early diagnosis and survival rates. Research studies and services internationally consistently observe socioeconomic and smoking-related inequalities in screening uptake. Pathway navigation (PN) is a process through which a trained pathway navigator guides people to overcome barriers to accessing healthcare services, including screening. This nested randomised controlled trial aims to determine whether a PN intervention results in more individuals participating in lung cancer screening compared with the usual written invitation within a previous non-responder population as part of the Yorkshire Lung Screening Trial (YLST).
    METHODS: A two-arm randomised controlled trial and process evaluation nested within the YLST. Participants aged 55-80 (inclusive) who have not responded to previous postal invitations to screening will be randomised by household to receive PN or usual care (a further postal invitation to contact the screening service for a lung health check) between March 2023 and October 2024. The PN intervention includes a postal appointment notification and prearranged telephone appointment, during which a pathway navigator telephones the participant, following a four-step protocol to introduce the offer and conduct an initial risk assessment. If eligible, participants are invited to book a low-dose CT (LDCT) lung cancer screening scan. All pathway navigators receive training from behavioural psychologists on motivational interviewing and communication techniques to elicit barriers to screening attendance and offer solutions.
    METHODS: The number undergoing initial telephone assessment of lung cancer risk. The number undergoing an LDCT screening scan.Secondary outcomes include demographic, clinical and risk parameters of people undergoing telephone risk assessment; the number of people eligible for screening following telephone risk assessment; the number of screen-detected cancers diagnosed; costs and a mixed-methods process evaluation.Descriptive analyses will be used to present numbers, proportions and quantitative components of the process evaluation. Primary comparisons of differences between groups will be made using logistic regression. Applied thematic analysis will be used to interpret qualitative data within a conceptual framework based on the COM-B framework. A health economic analysis of the PN intervention will also be conducted.
    BACKGROUND: The study is approved by the Greater Manchester West Research Ethics Committee (18-NW-0012) and the Health Research Authority following the Confidentiality Advisory Group review. Results will be shared through peer-reviewed scientific journals, conference presentations and on the YLST website.

    背景:尽管有许多技术进步,由于频繁的定位错误,支气管镜周围肺结节分析的诊断率仍然有限.基于针的共聚焦激光显微内窥镜(nCLE)可实现对针定位的实时显微反馈,有可能改善采样位置和诊断产量。以前的研究已经定义并验证了恶性肿瘤的nCLE标准,气道和肺实质。缺乏更大规模的研究证明nCLE对诊断产量的影响。我们的目的是研究与不使用nCLE的常规支气管镜检查相比,与常规支气管镜检查结合的nCLE成像是否会导致更高的诊断率。
    方法:这是一项平行组随机对照试验。招募在六个不同欧洲国家的大学和综合医院的肺科门诊诊所以及美国的一家医院进行。连续筛查怀疑有诊断性支气管镜检查指征的恶性周围肺结节(10-30mm)患者,将包括208名患者。将在两个程序之间进行基于网络的随机化(1:1)。主要结果是诊断产量。次要结果包括恶性肿瘤的诊断敏感性,针头重新定位,手术和透视持续时间,和并发症。病理学家将不知道程序类型;患者和内窥镜医师不会。

    背景:NCT06079970。
    BACKGROUND: Despite many technological advances, the diagnostic yield of bronchoscopic peripheral lung nodule analysis remains limited due to frequent mispositioning. Needle-based confocal laser endomicroscopy (nCLE) enables real-time microscopic feedback on needle positioning, potentially improving the sampling location and diagnostic yield. Previous studies have defined and validated nCLE criteria for malignancy, airway and lung parenchyma. Larger studies demonstrating the effect of nCLE on diagnostic yield are lacking. We aim to investigate if nCLE-imaging integrated with conventional bronchoscopy results in a higher diagnostic yield compared with conventional bronchoscopy without nCLE.
    METHODS: This is a parallel-group randomised controlled trial. Recruitment is performed at pulmonology outpatient clinics in universities and general hospitals in six different European countries and one hospital in the USA. Consecutive patients with a for malignancy suspected peripheral lung nodule (10-30 mm) with an indication for diagnostic bronchoscopy will be screened, and 208 patients will be included. Web-based randomisation (1:1) between the two procedures will be performed. The primary outcome is diagnostic yield. Secondary outcomes include diagnostic sensitivity for malignancy, needle repositionings, procedure and fluoroscopy duration, and complications. Pathologists will be blinded to procedure type; patients and endoscopists will not.
    BACKGROUND: Primary approval by the Ethics Committee of the Amsterdam University Medical Center. Dissemination involves publication in a peer-reviewed journal.

  • 文章类型: Clinical Trial Protocol
    背景:肺癌(LC)是全球癌症相关死亡的最常见原因。它的早期检测可以通过CT扫描来实现。两项大型随机试验证明了基于低剂量CT(LDCT)的肺癌筛查(LCS)在高危人群中的有效性。特异性死亡率下降20%-25%。尽管如此,大规模实施LCS面临障碍,因为适合合格人群的胸部放射科医生和CT扫描数量少,假阳性筛查结果频率高,结节不确定时间长达24个月,这是长期焦虑和多次昂贵的检查的来源,可能有副作用。深度学习,人工智能解决方案在检测肺结节并对其进行表征的回顾性试验中显示出有希望的结果。然而,到目前为止,还没有前瞻性研究证明它们在现实生活中的重要性。
    方法:这项开放标签的随机对照研究侧重于50-80岁的LCS患者,抽了20多年烟的人,无论是活跃还是戒烟不到15年前。其目的是确定是否协助多学科团队(MDT)进行基于3D卷积网络的筛查胸部CT扫描分析,以加速将结节明确分类为恶性或良性。将包括2722名患者,目的是证明肺结节检测与其确定的良性或恶性分类之间的延迟减少3个月。
    背景:这项研究的发起人是尼斯大学医院。法国伦理委员会CPP(保护委员会)Sud-Ouestetoutre-merIII(编号2022-A01543-40)和2023年12月的国家医疗和生产署(卫生部)。试验结果将通过同行评审的期刊以及国家和国际会议报告进行传播。
    背景:NCT05704920。
    BACKGROUND: Lung cancer (LC) is the most common cause of cancer-related deaths worldwide. Its early detection can be achieved with a CT scan. Two large randomised trials proved the efficacy of low-dose CT (LDCT)-based lung cancer screening (LCS) in high-risk populations. The decrease in specific mortality is 20%-25%.Nonetheless, implementing LCS on a large scale faces obstacles due to the low number of thoracic radiologists and CT scans available for the eligible population and the high frequency of false-positive screening results and the long period of indeterminacy of nodules that can reach up to 24 months, which is a source of prolonged anxiety and multiple costly examinations with possible side effects.Deep learning, an artificial intelligence solution has shown promising results in retrospective trials detecting lung nodules and characterising them. However, until now no prospective studies have demonstrated their importance in a real-life setting.
    METHODS: This open-label randomised controlled study focuses on LCS for patients aged 50-80 years, who smoked more than 20 pack-years, whether active or quit smoking less than 15 years ago. Its objective is to determine whether assisting a multidisciplinary team (MDT) with a 3D convolutional network-based analysis of screening chest CT scans accelerates the definitive classification of nodules into malignant or benign. 2722 patients will be included with the aim to demonstrate a 3-month reduction in the delay between lung nodule detection and its definitive classification into benign or malignant.
    BACKGROUND: The sponsor of this study is the University Hospital of Nice. The study was approved for France by the ethical committee CPP (Comités de Protection des Personnes) Sud-Ouest et outre-mer III (No. 2022-A01543-40) and the Agence Nationale du Medicament et des produits de Santé (Ministry of Health) in December 2023. The findings of the trial will be disseminated through peer-reviewed journals and national and international conference presentations.

  • 文章类型: Clinical Trial Protocol
    背景:在一小部分患者中,CT扫描发现的肺结节是早期肺癌。早期发现的肺癌具有更好的预后。英国胸科学会关于肺结节管理的指南建议使用多变量恶性肿瘤风险预测模型来辅助管理。虽然这些指南在临床实践中似乎是有效的,最近的数据表明,基于人工智能(AI)的恶性结节预测解决方案可能优于现有模型。
    方法:本研究是前瞻性的,观察性的多中心研究,以评估AI辅助的基于CT的肺癌预测工具(LCP)的临床实用性,以管理偶然的实性和部分实性肺结节患者与标准治疗。将从12家不同的英国医院招募2000名患者。主要结果是标准护理和LCP指导护理在评估基线CT扫描后,良性结节和癌症患者出院率方面的差异。次要结局调查对临床指南的依从性,其他改变临床管理的措施,患者预后和成本效益。
    背景:这项研究已经由英国中南部牛津研究伦理委员会(REC参考号:22/SC/0142)进行了审查并给出了有利的意见。研究结果将在开放获取期刊上进行同行评审后公开发布。在研究结果可用之前,计划举行患者和公众参与小组研讨会,以讨论传播结果的最佳方法。研究结果也将反馈给参与组织,以告知培训和采购活动。
    背景:NCT05389774。
    In a small percentage of patients, pulmonary nodules found on CT scans are early lung cancers. Lung cancer detected at an early stage has a much better prognosis. The British Thoracic Society guideline on managing pulmonary nodules recommends using multivariable malignancy risk prediction models to assist in management. While these guidelines seem to be effective in clinical practice, recent data suggest that artificial intelligence (AI)-based malignant-nodule prediction solutions might outperform existing models.
    This study is a prospective, observational multicentre study to assess the clinical utility of an AI-assisted CT-based lung cancer prediction tool (LCP) for managing incidental solid and part solid pulmonary nodule patients vs standard care. Two thousand patients will be recruited from 12 different UK hospitals. The primary outcome is the difference between standard care and LCP-guided care in terms of the rate of benign nodules and patients with cancer discharged straight after the assessment of the baseline CT scan. Secondary outcomes investigate adherence to clinical guidelines, other measures of changes to clinical management, patient outcomes and cost-effectiveness.
    This study has been reviewed and given a favourable opinion by the South Central-Oxford C Research Ethics Committee in UK (REC reference number: 22/SC/0142).Study results will be available publicly following peer-reviewed publication in open-access journals. A patient and public involvement group workshop is planned before the study results are available to discuss best methods to disseminate the results. Study results will also be fed back to participating organisations to inform training and procurement activities.

  • 文章类型: Clinical Trial Protocol
    背景:肺癌是全球癌症死亡的最常见原因,大多数患者患有广泛的疾病。尽管新的系统性抗癌治疗形成了当前的护理标准,但一年生存率正在改善,但仍然很低(37%)。虽然新疗法提高了生存率,大多数患者在治疗后有残留病,很少有人知道如何最好地管理它。因此,英国各地的残留疾病管理各不相同,一些患者仅接受维持性全身抗癌治疗,而另一些患者接受局部巩固治疗(LCT),同时维持全身抗癌治疗。LCT可以是手术的组合,放射治疗和/或消融,以去除肺部和全身所有剩余的癌症。这是密集的,价格昂贵,影响生活质量,但是我们不知道它是否能带来更好的生存,对生活质量的影响程度以及医疗保健提供者的成本可能是多少。RAMON研究(晚期非小细胞肺癌的治疗)将评估可接受性,晚期肺癌一线全身治疗后LCT与无LCT的疗效和成本-效果.
    方法:RAMON是一个实用的开放多中心,平行组,优势随机对照试验。我们的目标是从英国40家NHS医院招募244名年龄在18岁及以上的晚期非小细胞肺癌患者。参与者将以1:1的比例随机分配接受LCT以及维持治疗,或单独维持治疗。LCT将针对每个患者的特定疾病部位进行定制。参与者将被跟踪至少2年。主要结果是随机分组的总生存率。
    背景:苏格兰西部研究伦理委员会(22/WS/0121)于2022年8月获得伦理批准,并于2022年9月获得卫生研究管理局的批准。参与者将在参与研究之前提供书面知情同意书。调查结果将在国际会议上提交,在同行评审的出版物中,通过患者组织和通知患者。
    背景:ISRCTN11613852。
    Lung cancer is the most common cause of cancer death worldwide and most patients present with extensive disease. One-year survival is improving but remains low (37%) despite novel systemic anti-cancer treatments forming the current standard of care. Although new therapies improve survival, most patients have residual disease after treatment, and little is known on how best to manage it. Therefore, residual disease management varies across the UK, with some patients receiving only maintenance systemic anti-cancer treatment while others receive local consolidative treatment (LCT), alongside maintenance systemic anti-cancer treatment. LCT can be a combination of surgery, radiotherapy and/or ablation to remove all remaining cancer within the lung and throughout the body. This is intensive, expensive and impacts quality of life, but we do not know if it results in better survival, nor the extent of impact on quality of life and what the cost might be for healthcare providers. The RAMON study (RAdical Management Of Advanced Non-small cell lung cancer) will evaluate the acceptability, effectiveness and cost-effectiveness of LCT versus no LCT after first-line systemic treatment for advanced lung cancer.
    RAMON is a pragmatic open multicentre, parallel group, superiority randomised controlled trial. We aim to recruit 244 patients aged 18 years and over with advanced non-small-cell lung cancer from 40 UK NHS hospitals. Participants will be randomised in a 1:1 ratio to receive LCT alongside maintenance treatment, or maintenance treatment alone. LCT will be tailored to each patient\'s specific disease sites. Participants will be followed up for a minimum of 2 years. The primary outcome is overall survival from randomisation.
    The West of Scotland Research Ethics Committee (22/WS/0121) gave ethical approval in August 2022 and the Health Research Authority in September 2022. Participants will provide written informed consent before participating in the study. Findings will be presented at international meetings, in peer-reviewed publications, through patient organisations and notifications to patients.

  • 文章类型: Journal Article
    目的:Pembrolizumab是一种程序性细胞死亡蛋白-1(PD-1)抑制剂,用于治疗程序性细胞死亡配体-1(PD-L1)肿瘤比例评分(TPS)≥50的晚期非小细胞肺癌(NSCLC)患者。英国尚未评估基于TPS的分层的进一步细分,尽管吸烟引起的肿瘤突变负担和先前放疗的免疫原性作用被认为可以改善反应。
    目的:调查PD-L1TPS是否≥80%,在接受pembrolizumab单药治疗的NSCLC患者中,治疗前或治疗后2个月内的吸烟状况或放疗会影响无进展生存期(PFS).
    方法:PD-L1TPS,我们比较了2017年11月1日至2022年2月18日期间接受派姆单抗单药治疗的NSCLC患者(n=100)吸烟状况和放疗暴露情况.使用对数秩分析比较了生存估计值,Cox比例风险分析用于研究潜在混杂因素的影响,包括肿瘤分期和表现状态。
    结果:与PD-L1TPS50-79%和PD-L1TPS≥80%的患者相比,PFS没有显着差异(log-rankHR=0.330,p=0.566)。吸烟者的PFS明显改善(对数秩HR=4.867,p=0.027),而接受放疗的患者PFS显着降低(log-rankHR=6.649,p=0.012)。Cox回归模型证实,放疗(p=0.022)和表现状态(p=0.009)是PFS的独立阴性预测因子。
    结论:更严格的PD-L1TPS分层不影响生存结果。吸烟史改善PFS,虽然它不是一个独立的反应预测因子,而放疗和表现状态独立影响临床反应。我们建议不需要进一步分层PD-L1TPS,而在NSCLC患者中,表现状态和放疗可能是pembrolizumab应答的其他临床有用的生物标志物.
    Pembrolizumab is a programmed cell death protein-1 (PD-1) inhibitor used to treat advanced patients with non-small cell lung cancer (NSCLC) with a programmed cell death ligand-1 (PD-L1) tumour proportion score (TPS) ≥50. Further sub-division of TPS-based stratification has not been evaluated in the UK, although smoking-induced tumour mutational burden and the immunogenic effects of prior radiotherapy are suggested to improve response.
    To investigate if PD-L1 TPS ≥80%, smoking status or radiotherapy before or within 2 months of treatment influenced progression-free survival (PFS) in patients with NSCLC treated with pembrolizumab monotherapy.
    PD-L1 TPS, smoking status and radiotherapy exposure were compared in patients with NSCLC in National Health Service (NHS) Tayside (n=100) treated with pembrolizumab monotherapy between 1 November 2017 and 18 February 2022. Survival estimates were compared using log-rank analysis, and Cox proportional hazards analysis was used to investigate the influence of potential confounding factors, including tumour stage and performance status.
    PFS was not significantly different (log-rank HR=0.330, p=0.566) comparing patients with PD-L1 TPS 50-79% and PD-L1 TPS ≥80%. Smokers had significantly improved PFS (log-rank HR=4.867, p=0.027), while patients receiving radiotherapy had significantly decreased PFS (log-rank HR=6.649, p=0.012). A Cox regression model confirmed that both radiotherapy (p=0.022) and performance status (p=0.009) were independent negative predictors of PFS.
    More rigorous PD-L1 TPS stratification did not influence survival outcomes. Smoking history improved PFS, although it was not an independent response predictor, while radiotherapy and performance status independently influenced clinical response. We suggest that further stratification of PD-L1 TPS is not warranted, while performance status and radiotherapy treatment may be additional clinically useful biomarkers of response to pembrolizumab in patients with NSCLC.

    背景:肺结节是最常见的疾病之一。医学影像学方法对鉴别恶性结节和良性结节具有较高的假阳性率。因此,开发高精度筛查恶性结节的新技术对肺结节监测具有重要意义。使用流式细胞术检测血液巨噬细胞中的生物标志物(巨噬细胞/巨噬细胞中的表位检测)为癌症的早期和非侵入性诊断开辟了新时代。这项计划中的研究旨在检查外周血巨噬细胞因子Apo10和TKTL1是否准确区分恶性结节和良性结节。
    方法:我们计划在这项研究中招募3825名患有肺结节的参与者,他们将在中山大学肿瘤中心参加他们的年度体检。所有患者的Apo10和TKTL1水平将在他们最后一餐后60分钟在他们的3年随访期间进行测试。将收集活检或手术病理结果作为金标准,以评估Apo10和TKTL1在区分恶性结节和良性结节方面的准确性。敏感性,特异性,正预测值,负预测值和接收工作特性曲线下的面积也将被评估。
    背景:该研究得到了中山大学医学伦理委员会的批准(SL-G2022-005-02)。这项研究的结果将在国际科学会议的同行评审出版物和演讲中传播,也将传播给与会者。
    背景:ChiCTR2300073823;预结果。
    Lung nodules are one of the most prevalent diseases. Medical imaging methods have a high false positive rate for distinguishing malignant nodules from benign nodules. Therefore, developing new technologies with high accuracy for screening malignant nodules is of great importance for lung nodule surveillance. Use of flow cytometry to detect biomarkers in blood macrophages (epitop detect in macrophages/macrophages) has opened a new era for early and noninvasive diagnosis of cancer. This planned study aims to examine whether the peripheral blood macrophage factors Apo10 and TKTL1 accurately distinguish malignant nodules from benign nodules.
    We plan to enrol in this study 3825 participants with lung nodules who will attend their annual physical examination at Sun Yat-sen University Cancer Center. Apo10 and TKTL1 levels in all patients will be tested at 60 min after their last meal every 6 months during their 3-year follow-up. Biopsy or surgical pathology results will be collected as the gold standard to assess the accuracy of Apo10 and TKTL1 in distinguishing malignant nodules from benign nodules. The sensitivity, specificity, positive predictive value, negative predictive value and area under the receiving operating characteristic curve will also be evaluated.
    The study is approved by the medical ethics committee of Sun Yat-sen University (SL-G2022-005-02). The results of this study will be disseminated in peer-reviewed publications and presentations at international scientific meetings and will also be disseminated to the participants.

  • 文章类型: Comparative Study
    目的:本研究有两个目的:探索黑人/非裔美国人(BAA)肺癌患者的诊断经验,以查明陷阱,与其他种族背景的患者相比,次优的经验和歧视导致结果差异的实例,尤其是白人患者。第二个目标是确定导致BAA患者肺癌诊断中健康差异的根本原因。
    方法:我们采用了现象学研究方法,指导对自我识别为BAA诊断为肺癌的患者进行深入访谈,以及护理人员,医疗保健专业人员和社区倡导者了解BAA肺癌的经验。我们进行了主题分析,以确定患者的经历,初级保健和专科水平。使用国家少数民族健康与健康差异研究所(NIMHD)健康差异模型确定了促成因素。
    结果:从2021年3月至11月,我们对19名参与者进行了个别访谈,包括9名患者/护理人员和10名提供者/倡导者。参与者报告在寻求治疗前疼痛复发和增加,治疗非癌症疾病,诊断测试和转诊的延误,与专家和初级保健提供者打交道时沟通不畅和偏见。导致次优体验的因素包括保险公司不愿承担成本,提供商不愿进行全面测试,提供者在推荐治疗时的偏见,医疗费用高,缺乏医疗设施和合格的工作人员来提供必要的支持。然而,一些参与者报告说,由于他们的保险,他们有积极的经验,服务的可用性,并拥有授权的支持结构。
    结论:BAA患者和护理人员在护理期间遇到了不理想的经历。NIMHD模型是一个有用的框架,可以组织可能导致健康差异的这些经历的因素。需要进一步的研究来充分捕获这些经历的程度,并确定改善BAA患者在肺癌诊断途径中的经历的方法。
    This study has two objectives: first, to explore the diagnostic experiences of black/African American (BAA) patients with lung cancer to pinpoint pitfalls, suboptimal experiences and instances of discrimination leading to disparities in outcomes compared with patients of other ethnic backgrounds, especially white patients. The second objective is to identify the underlying causes contributing to health disparities in the diagnosis of lung cancer among BAA patients.
    We employed a phenomenological research approach, guiding in-depth interviews with patients self-identifying as BAA diagnosed with lung cancer, as well as caregivers, healthcare professionals and community advocates knowledgeable about BAA experiences with lung cancer. We performed thematic analysis to identify experiences at patient, primary care and specialist levels. Contributing factors were identified using the National Institute of Minority Health and Health Disparities (NIMHD) health disparity model.
    From March to November 2021, we conducted individual interviews with 19 participants, including 9 patients/caregivers and 10 providers/advocates. Participants reported recurring and increased pain before seeking treatment, treatment for non-cancer illnesses, delays in diagnostic tests and referrals, poor communication and bias when dealing with specialists and primary care providers. Factors contributing to suboptimal experiences included reluctance by insurers to cover costs, provider unwillingness to conduct comprehensive testing, provider bias in recommending treatment, high healthcare costs, and lack of healthcare facilities and qualified staff to provide necessary support. However, some participants reported positive experiences due to their insurance, availability of services and having an empowered support structure.
    BAA patients and caregivers encountered suboptimal experiences during their care. The NIMHD model is a useful framework to organise factors contributing to these experiences that may be leading to health disparities. Additional research is needed to fully capture the extent of these experiences and identify ways to improve BAA patient experiences in the lung cancer diagnosis pathway.

  • 文章类型: Journal Article
    目的:评估过去15年在法国接受肺癌手术的患者的质量指标(30天死亡率和抢救失败)的演变,并研究潜在的影响因素。
    方法:使用来自法国医院数据库(PMSI)的数据进行回顾性队列研究。
    方法:全国人群研究。
    方法:所有在法国(2005-2020)接受肺癌肺切除术的患者(N=157566)。患者特征(年龄、性别,合并症),手术(手术方法,切除类型,切除范围)和医院(医院类型,肺切除术的医院容积)被取回。
    方法:我们研究了两个结局指标:30天死亡率和抢救失败。我们使用基于回归的技术(包括中断的时间序列)来评估患者和医院特征对30天死亡率和抢救失败的影响(30天内至少有一个主要术后并发症的患者的死亡人数术后)。调整案例组合。
    结果:30天死亡率从2005年的3.8%上升到2010年的4.9%,然后下降到2020年的2.9%。救援失败率从2005年的12.2%下降到2020年的7.1%。随着时间的推移,肺切除术率显着下降(2005年为18.1%,2020年为4.8%),并且在两个时期(2005-2010/2015-2020)之间对死亡率降低的贡献最大。使用电视胸腔镜手术或机器人辅助手术对降低两个时期的死亡率(观察到的死亡率差异的16%)有很大的影响,医院数量也是如此。
    结论:手术实践的变化,特别是肺切除术的减少,可能是2011年以来法国术后死亡率降低和抢救失败的主要原因之一。医院数量是降低术后死亡率的另一个重要因素。我们的研究应该鼓励使用技术或组织创新,例如手术实践和癌症手术授权的变化,提高护理质量。
    To estimate the evolution of quality indicators (30-day mortality and failure-to-rescue) inpatients who underwent lung cancer surgery in France over the past 15 years and to study the potential influencing factors.
    Retrospective cohort study using data from the French hospital database (PMSI).
    Nationwide population-based study.
    All patients who underwent pulmonary resection for lung cancer in France (2005-2020) were included (N=1 57 566). Characteristics of patients (age, gender, comorbidities), surgery (surgical approach, type of resection, extent of resection) and hospital (type of hospital, hospital volume for pulmonary resections) were retrieved.
    We studied two outcome indicators: 30-day mortality and failure-to-rescue. We used regression-based techniques (including interrupted time-series) to assess the effects of patient and hospital characteristics on 30-day mortality and failure-to-rescue (number of deaths among patients with at least one major postoperative complication within the 30 days after surgery), adjusting for case mix.
    The 30-day mortality rate increased from 3.8% in 2005 to 4.9% in 2010 and then decreased to 2.9% in 2020. The failure-to-rescue rate decreased from 12.2% in 2005 to 7.1% in 2020. The pneumonectomy rate decreased significantly over time (18.1% in 2005 to 4.8% in 2020) and had the greatest contribution on the reduction of mortality between two periods (2005-2010/2015-2020). The use of video-assisted thoracoscopic surgery or robot-assisted surgery had a great influence on the reduction of mortality (16% of the observed difference in mortality) between the two periods, as did hospital volume.
    The change in surgical practices, particularly the reduction in pneumonectomies, could be one of the main reasons for reduction in postoperative mortality and failure-to-rescue in France since 2011. Hospital volume is another important factor in reducing postoperative mortality. Our study should encourage the use of technological or organisational innovation, such as changes in surgical practice and cancer surgery authorisations, to improve quality of care.
