Chemotherapy,
while undeniably effective in controlling or eradicating a variety of
neoplasms, is also accompanied by a number of toxicities. Foremost among
these is neutropenia, which places the pediatric cancer patient at risk
for serious fungal infections. The fungal organisms most commonly
responsible for infection in neutropenic children are Candida,
Aspergillus, Mucor, and the Phycomycetes. Common sites of infection
include the oral cavity, sinuses, lung, and bloodstream. Recently,
candidal infection of the liver was recognized as a growing problem.
Diagnosis of deep-seated fungal infections, such as pneumonia and
hepatic candidiasis, is extremely difficult, often requiring open-lung
or liver biopsy, which a patient's hematologic status may not permit.
Because early treatment significantly improves prognosis, empirical
antifungal therapy may be indicated in selected patients. Amphotericin B
is currently the antifungal agent of choice against most fungal
organisms. Antifungal efficacy studies based on animal models of
disseminated candidal infection suggest that amphotericin B combined
with 5-fluorocytosine (5-FC) is more effective than amphotericin B alone
against most deep-seated Candida infections. The investigational drug,
fluconazole, appears as effective as amphotericin B plus 5-FC in the
prevention and early treatment of disseminated candidiasis, and clinical
trials to assess this potentially important role for the new antifungal
agent are now being initiated.
