Usefulness of Interferon-gamma Release Assay in Diagnosing Pulmonary Nodules

Solitary Pulmonary Nodule Clinical Trial

Official title:
Usefulness of Interferon-gamma Release Assay in Diagnosing Pulmonary Nodules

Clinical Trial Summary

Among the causes of the solitary pulmonary nodule (SPN), benign causes including tuberculosis was noted on 15 to 60 percents in various studies.

Although the characteristics of chest imaging is helpful in diagnosis and percutaneous needle biopsy for pulmonary nodule has been represented high diagnostic yield in many reports, but still surgical biopsy has been needed in definite diagnosis of pulmonary nodules in many cases.

The aim of this study is to evaluate the usefulness of interferon-gamma release assay in addition to the percutaneous needle biopsy, in diagnosis of pulmonary nodules.

Clinical Trial Description

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. ;
