Routine full-lung tomography in the initial staging and treatment planning of patients with Hodgkin's disease and non-Hodgkin's lymphoma

The yield of additional information from anteroposterior full-lung tomograms that changed stage or treatment, in comparison to that obtained from routine chest radiographs, was prospectively evaluated in 243 previously untreated patients with Hodgkin's disease and non-Hodgkin's lymphoma. Although new information was found in 21.4% of all patients, in only 1.2% did these additional data change patient staging. In 3.3% of the other patients the tomograms provided information that affected radiotherapy treatment planning as practiced in our institution.
