CT evaluation of patients during treatment of advanced non-small cell lung carcinoma.
Twenty-one patients with Stage III non-small cell bronchogenic carcinoma were studied by chest radiograph and computed tomography (CT) before and after chemotherapy. In three patients (14%), the prechemotherapy CT showed measurable disease not seen on chest radiograph. Postchemotherapy CT scans showed additional measurable disease not seen on chest x-ray films in nine of 56 (16%) follow-up exams. This represented additional disease in seven of the 21 patients (33%). The CT findings resulted in a significant change in therapy in six of the 21 patients (29%).
