Official title
Korean Multicenter Prospective Cohort of Diagnostic Bronchoscopy for Peripheral Lung Lesions
Overview
The primary objective is To evaluate the usefulness and safety of advanced guided bronchoscopy for histological diagnosis of peripheral pulmonary lesions. The Secondary objective is to establish a strategy that can most effectively use endoscopes for early diagnosis of lung cancer in a real-world care environment by identifying patient/clinical/image/procedure-related characteristics that can optimize the practicality of emerging technologies.
Detailed description
* Patients with peripheral pulmonary lesions who need histological diagnosis due to suspected lung cancer and whose lesions are judged capable of histological examination through guided bronchoscopy will be prospectively recruited. * This study is a pure non-interventional pragmatic design. In addition to biopsy for lung lesions using bronchoscopy, lung cancer staging and tests necessary for metastases and treatment for diagnosed lung cancer are performed according to existing guidelines and the judgment of medical staff. * We will analyze the clinical characteristics of guided bronchoscopy procedures used in clinical practice and the main results during the follow-up period of up to one year (diagnostic yield, sensitivity, safety, practicality, and various factors affecting usefulness).
Interventions
- Device Guided bronchoscopy
It is performed when a pulmonary lesion with a possibility of malignancy is found on chest CT and histological diagnosis and differentiation are required.
Primary outcome measures
- Diagnostic yield at index [Time frame: Upon reports of pathologic results (up to 2 weeks after bronchoscopy)]
Secondary outcome measures (3)
- Diagnostic accuracy at 12 months [Time frame: Confirmed by follow-up results at 1 year]
- Sensitivity for malignancy [Time frame: Confirmed by follow-up results at 1 year]
- Complication [Time frame: Confirmed by follow-up results at 1 year]
Eligibility criteria
