Abstract:
As lymph node metastasis is the most important factor determining the surgical outcome of lung cancer, we evaluated the accuracy and clinical usefulness of functional imaging with integrated positron-emission tomography and computed tomography in nodal staging of non-small-cell lung cancer. Between October 2003 and August 2004, 43 newly diagnosed patients underwent curative surgical resection or mediastinoscopic nodal biopsy after chest computed tomography as well as whole-body functional imaging for clinical staging. Based on histopathologic findings in the lymph nodes, we compared the diagnostic usefulness of computed tomography and functional imaging. Twenty-two patients were N0 stage, 6 were N1, 11 were N2, and 4 were N3. Although functional imaging seemed to be superior for evaluation of N2 nodes, there were no significant differences in the sensitivity, specificity, positive-predictive value, negative-predictive value, or accuracy. The situation was similar for N1 nodes, and there were no significant differences except for the false-negative rate. High false-positive and negative-rates for N2 lymph nodes suggest that functional imaging should not replace mediastinoscopy.
