研究目的:

基于cfDNA甲基化特征开发肺结节良恶性诊断模型,评估其在直径<30 mm肺结节良恶性鉴别中的敏感性、特异性及整体诊断效能。 探讨基于cfDNA甲基化开发的肺结节良恶性诊断模型,对恶性肺结节是否发生侵袭(浸润性癌 vs 微浸润癌/原位癌)的鉴别能力,包括敏感性和特异性。 评估该cfDNA甲基化诊断模型在直径<10 mm肺结节的良恶性及侵袭性诊断效能。  

Objectives of Study:

To develop a cfDNA methylation-based diagnostic model for benign–malignant classification of pulmonary nodules and to evaluate its sensitivity, specificity, and overall diagnostic performance in patients with pulmonary nodules < 30 mm in diameter. To investigate the sensitivity and specificity of the cfDNA methylation-based diagnostic model for distinguishing invasive malignant pulmonary nodules (invasive carcinoma) from non-invasive malignant nodules (minimally invasive adenocarcinoma and carcinoma in situ). To evaluate the diagnostic performance of the cfDNA methylation-based model for benign–malignant classification and assessment of invasiveness in pulmonary nodules < 10 mm in diameter.

诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

以组织病理学诊断作为主要金标准。恶性肺结节需有明确病理诊断,并依据病理结果区分为原位癌/微浸润腺癌(AIS/MIA)及浸润性肺癌。良性肺结节以组织病理学诊断为参考标准。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

Histopathological diagnosis is used as the primary gold standard. Malignant pulmonary nodules must be confirmed by pathology, and classified as adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA) or invasive lung cancer according to pathological findings. Benign pulmonary nodules are determined by histopathology.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

基于外周血浆 cfDNA 甲基化检测技术的诊断试验。采集术前血浆样本,进行 cfDNA 甲基化建库与测序,提取特定甲基化位点特征,构建肺结节良恶性及侵袭性判别模型,用于评估其诊断效能。

Index test:

The index test is a diagnostic assay based on plasma cell-free DNA (cfDNA) methylation analysis. Preoperative peripheral blood samples are collected for cfDNA methylation library construction and sequencing. Methylation features from selected genomic regions are extracted to establish diagnostic models for differentiating benign and malignant pulmonary nodules and for assessing tumor invasiveness.

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

胸部 CT 检出肺部结节(最大径<30 mm)的成年受试者。研究对象需覆盖良性结节及不同侵袭程度的恶性肺结节,具有完整疾病谱和良好代表性。所有纳入病例均有明确结局判定(病理或随访诊断),并在手术或治疗前采集血浆样本。

例数:

Sample size:

180

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Adult patients with pulmonary nodules (maximum diameter <30 mm) detected by chest CT. The study population includes both benign nodules and malignant nodules with different degrees of invasiveness, representing a complete disease spectrum. All enrolled subjects have definitive outcome confirmation by pathology or clinical follow-up, and plasma samples are collected prior to surgical or therapeutic intervention.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:
