What are the recommendations for prophylactic antifungal use in cancer patients?
Prophylactic antifungal use is recommended for high-risk cancer patients, such as those undergoing hematopoietic stem cell transplantation or intensive chemotherapy for hematologic malignancies. Prophylaxis typically involves the use of fluconazole, posaconazole, or echinocandins, depending on the patient's risk factors and local resistance patterns.
