Invasive fungal infections are a common life-threatening disease and a major cause of morbidity, particularly in patients with malignancies, and Candida spp. is the most common isolated fungi in bloodstream. Candidemia is the focus of this review, which covers an approach to diagnosis and treatment, with an emphasis on patients with malignancies. Acute leukemia, lymphoma, or myelodysplastic syndrome are the most common hematological malignancies associated with candidemia, while among solid tumors, gastrointestinal cancer has the majority of fungemia cases. Epidemiologic trends show there is a discrepancy between malignancies, where there is an important prevalence of non-albicans Candida in hematological malignancy patients. Diagnosis is challenging, and a high index of suspicion is required to select at-risk patients for early empiric therapy with the goal of reducing mortality. There is an increased effort to improve understanding of individualized approaches to the patient based on precision medicine and to improve diagnosis in the future. The basis of treatment is prompt therapy with echinocandins and target therapy based on susceptibility and minimum inhibitory concentrations (MICs).
