纳入标准:

Inclusion criteria

排除标准:

1.CT图像表现为纯实性结节,或虽为部分实性结节但其实性成分占比超过50%。
2.CT图像存在严重呼吸运动伪影、金属伪影或噪声过高,影响结节征象的判读。
3.影像检查或获取病理标本的操作非在本院完成,或患者在本院检查后转至外院治疗。
4.在进行本次CT检查前,患者已针对该肺部结节接受过任何形式的抗感染、消融或手术等治疗。
5.经病理或临床随访证实已存在淋巴结转移或远处转移。

Exclusion criteria:

1.CT imaging demonstrates a pure solid nodule, or a part-solid nodule with a solid component ratio greater than 50%;
2.CT imaging is compromised by severe respiratory motion artifacts, metal artifacts, or high noise levels, hindering the assessment of nodule characteristics;
3.Imaging studies or tissue sampling were conducted outside our institution, or patients were referred to external facilities for treatment following their initial workup at our hospital;
4.Before undergoing the current CT scan, the patient had been subjected to any therapeutic intervention for the lung nodule, such as anti-infective treatment, ablation, or surgical resection;
5.It has been confirmed by pathology or clinical follow-up that lymph node metastasis or distant metastasis is present;

测量指标:

Outcomes:

指标中文名:

肺磨玻璃结节术后病理类型及浸润程度

指标类型:

主要指标

Outcome:

Pathological subtypes and extent of invasion following surgical resection of pulmonary ground-glass nodules

Type:

Primary indicator

测量时间点:

手术切除后病理诊断完成时(回顾性收集,为术后病理报告结果)

测量方法:

由病理科医师根据2021版WHO肺肿瘤分类标准,对手术切除标本进行病理诊断,将病变分为非典型腺瘤样增生(AAH)、原位腺癌(AIS)、微浸润性腺癌(MIA)、浸润性腺癌

Measure time point of outcome:

At the time of pathological diagnosis following surgical resection

Measure method:

Based on the 2021 WHO Classification of Thoracic Tumors, pathologists evaluated the resected specimens and classified the lesions as atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA), or invasive adenocarcinoma.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用标准化病例报告表(CRF)完成受试者信息采集,所有数据录入专业电子数据采集系统(EDC);系统内置逻辑核查、范围核查规则,保障数据完整性与准确性;建立数据核查、疑问管理、源数据溯源的标准化管理流程,全程遵循GCP规范开展数据管理工作。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection is performed via standardized Case Report Forms (CRF). All data is entered into an electronic data capture (EDC) system with built‑in logical and range validation rules. A standardized data management process including data monitoring, query resolution and source data verification is established in accordance with GCP guidelines.
