Abstract
|
|
|
Evaluation of mediastinal metastasis in patients with primary bronchogenic carcinoma
is important in determening therapeutic plan. Gallium67-scan was
prospectively compared as noninvasive means of evaluating mediastinal metastasis in 20
patients in whom surgical and histologic evaluations of mediastinum were performed.
Except one case of which histologic diagnosis was bronchioloalveolar cell carcinoma, all
primary tumors stowed uptake of Gallium67(uptake rate of primary tumor;
95%).
In 19 patients who showed uptake of primary tumor 5 patients had false negative
scan in evaluating mediastinal invasion but false positive scan was absent.
These results indicate a sensitivity of 58%, a specificity of 103%, an accuracy of 58%
for negative scan and an accuracy of 100% for positive scan. These data indicate that
Gallium67-scan is useful noninvasive method for detemening operability in
primary bronchogenic carcinoma.
