Invasive fungal infections are one of the leading causes of morbidity
and mortality in cancer patients. Amphotericin B deoxycholate is still
considered the gold standard of antifungal therapy, although the new
triazoles (itraconazole and, especially, fluconazole) have shown to be
able to replace amphotericin B for some therapeutic indications. The
new lipid formulations of amphotericin B have disclosed new therapeuti
c perspectives, especially in patients with severe renal failure and d
ocumented infections. At this time, indications, contraindications and
limitation of the various drugs in the antifungal armamentarium are s
till partially unclear. Antifungal prophylaxis with fluconazole may be
indicated in high-risk patients, although the duration of such prophy
laxis should be limited as much as possible, in order to prevent selec
tion of resistant strains and acquired resistance. Empirical antifunga
l therapy is used extremely widely (maybe, too widely) in many cancer
centres, despite being based on limited clinical data. For this indica
tion, fluconazole may also be effective in patients not receiving fluc
onazole prophylaxis, in whom Aspergillus infection is unlikely.
