Routine chest radiography for the evaluation of febrile neutropenic patients after autologous stem cell transplantation.

Chest radiographs are routinely obtained for diagnostic evaluation of neutropenic febrile patients. We investigated the frequency of chest radiographic abnormalities during febrile episodes after autologous PBSC transplants and assessed the relationship of these abnormalities to past history of pulmonary disease, pre-transplant chest radiographic abnormalities, and pulmonary signs or symptoms at time of fever. We also studied the impact of chest radiographic findings on patient management. Sixty-one consecutive adult autologous PBSC transplant recipients were studied. Fifty-two (85%) developed fever, and 20 (38%) of these showed new chest radiographic abnormalities suggestive of pulmonary infection. Patients with pre-transplant chest radiographic abnormalities were more likely to develop additional abnormalities with fever post-transplant. Pulmonary symptoms or signs had low sensitivity or specificity for predicting radiographic abnormalities. Only 40% of patients with pulmonary symptoms or signs had an abnormal chest radiograph. Twenty-six percent of patients with abnormal chest radiographs had no clinical findings suggestive of pulmonary infection. The identification of chest radiographic abnormality did not change empiric antibiotic treatment in any patient. The role of routine chest radiography for diagnostic evaluation of febrile autologous PBSC transplant patients should be re-evaluated. Copyright 2000 Wiley-Liss, Inc.
