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.
