Study design:

Sequential 

研究目的:

1.筛选流域分析法术中定位不易触及肺结节失败的独立危险因素; 2.基于独立危险因素构建列线图预测模型,并验证模型的区分度、校准度及临床净获益。  

Objectives of Study:

1. Screening of independent risk factors for failed localization of inaccessible pulmonary nodules in watershed analysis; 2. Construction of a nomogram prediction model based on the independent risk factors, and verification of the model's discrimination, calibration, and clinical net benefit.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.胸部高分辨率 CT 证实为周围型肺结节(位于肺外野 1/3),直径8-20mm; 2.术前临床怀疑早期肺癌(磨玻璃成分占比≥50% 或结节倍增时间≥400 d); 3.已尝试行流域分析法定位及胸腔镜下楔形肺切除术; 4.临床、影像学及随访资料完整。

Inclusion criteria

1. Peripheral pulmonary nodules confirmed by chest high-resolution CT (located in the outer 1/3 of the lung field), with a diameter of 8–20 mm; 2. Preoperative clinical suspicion of early-stage lung cancer (ground-glass component proportion >=50% or nodule doubling time >=400 days); 3. Attempted localization using watershed analysis and video-assisted thoracoscopic wedge resection; 4. Complete clinical, imaging, and follow-up data.

排除标准:

1.严重基础疾病(心力衰竭等)无法耐受手术; 2.术中更改手术方式(转开胸或进行肺叶/肺段切除术等); 3.临床资料不全者。

Exclusion criteria:

1. Severe underlying diseases (e.g., heart failure) that preclude tolerance of surgery; 2. Intraoperative change of surgical approach (conversion to thoracotomy or performance of lobectomy/segmentectomy, etc.); 3. Incomplete clinical data.
