Usefulness of Interferon-gamma Release Assay in Diagnosing Pulmonary Nodules
Among the patients who failed to diagnosis by percutaneous needle biopsy and needed to have
Surgical biopsy, thirty percents of the patients were diagnosed as benign nodules and about
six percents were diagnosed as tuberculosis in Seoul National University Hospital during
2007-2008.
The investigators want to know whether conducting an interferon-gamma release assay in
addition to percutaneous needle biopsy is helpful in diagnosis of lung nodules.
Inclusion Criteria:
- Age> 18 years
- in patients with solitary pulmonary nodule
- who had percutaneous needle biopsy for diagnosis of lung nodule
Exclusion Criteria:
- patients who do not agree the study enrollment
Type of Study:
Observational
Study Design:
Observational Model: Case-Only, Time Perspective: Prospective
Outcome Measure:
Positive rate of the interferon-gamma release assay
Outcome Description:
the result of the interferon-gamma release assay is reported in three different categories as positive, negative or indeterminate. We want to know whether the positive rate of the interferon-gamma release asssay would be significantly different according to the pathologic diagnosis of lung nodules confirmed by percutaneous needle biopsy.
Outcome Time Frame:
within 36hrs after blood sampling
Safety Issue:
No
Authority:
Korea: Institutional Review Board
