Malignancy
NO
To evaluate effective methods and equipments for endobronchial ultrasound-guided biopsy targeting hilar/mediastinal lymph nodes or hilar/mediastinal lesions in clinical practice.
Safety,Efficacy
Calculation of diagnostic yields for each method with endobronchial ultrasound bronchoscope for hilar and mediastinal lesions and hilar and mediastinal lymph node.
1. Evaluation of diagnostic yields by biopsy devises
2. Evaluation of adverse events associated with biopsies
3. Evaluation of the relationship between diagnostic yields and flow cytometry
4. Evaluation of the relationship between diagnostic yields and rapid on-site cytological evaluation (ROSE)
5. Evaluation of the relationship between diagnostic yields and the number of biopsies and tissue specimens
6. Evaluation of the relationship between target lesion sizes and diagnostic yields
7. Evaluation of diagnostic yields for EBUS-TBNA alone versus EBUS-TBNA preceded by EBUS-IFB/MFB or EBUS-TMC
8. Evaluation of diagnostic yields for EBUS-TBNA alone versus the combined diagnostic yields of EBUS-TBNA with EBUS-IFB/MFB and EBUS-TMC
Observational
| 18 | years-old | <= |
| Not applicable |
Male and Female
1. Patients with hilar/mediastinal lesions and/or lymph nodes, where malignant lymphoma lesions are considered.
2. 18 years or older
3. Informed consent
1. Patients who are already diagnosed malignant lymphoma pathologically by other lesions.
