title: Mucormycosis-associated fungal infections in patients with haematologic malignancies.
abstract: Among patients with haematologic disorders, mucormycosis most commonly occurs in those with acute leukaemia or lymphoma who have developed neutropenia due to malignancy or to chemotherapy, and in transplanted patients receiving immunosuppressive treatment. Here, we aim to present a retrospective study conducted over a 5-year period (2001-2005). The study included 20 patients with haematologic malignancies with a proven mucormycosis admitted in Medical Oncology Divisions in Cukurova University Hospital. The most frequent sites of infection were paranasal sinuses (95%) and lung (5%). Antifungal treatment was empirically administered in 18 (90%) patients; 18 patients underwent radical surgical debridement (90%). The therapy was successful for only eight patients (40%). Eleven patients died within 1 months of the diagnosis of fungal infection: the cause of death was only by mucormycosis in four patients (36.6%), mucormucosis and systematic inflamatuar response syndrome (SIRS) in two patients (18.2%) and progression of haematologic disease in five patients (45.5%). At univariate analysis, the factors that correlated with a positive outcome from infection were the following: amphotericin B treatment, neutrophil recovery from postchemotherapy aplasia. At multivariate analysis, the factors that significantly correlated with recovery from infection were the liposomal amphotericin B treatment (p = 0.026), doses of L-AmB (p = 0.008) and the length of the treatment (p = 0.01), respectively. It seems to have increased in recent years. Although a reduction of mortality has been observed recently, the mortality rate still remains high. Extensive and aggressive diagnostic and therapeutic procedures are essential to improve the prognosis in these patients.
