Infection is a major cause of morbidity and mortality in patients with neoplastic disease because of compromised host defenses. These defects result in an increased risk of infection and its complications. The nature of the underlying malignancy, the immunodeficiencies associated with it, and the treatments directed against it are all important determinants of infection. In recent years, the introduction of more intensive chemotherapeutic regimes and the widespread use of bone marrow and peripheral stem cell transplantation have changed the pattern of infection in many patients. Furthermore,...
