ABSTRACT
IDH1/2 mutations are common in acute myeloid leukemia (AML) and represent a therapeutic target. The GIMEMA AML1516 observational protocol was designed to study the prevalence of IDH1/2 mutations and associations with clinico-biological parameters in a cohort of Italian AML patients. We analyzed a cohort of 284 AML consecutive patients at diagnosis, 139 females and 145 males, of a median age of 65 years (range: 19−86). Of these, 38 (14%) harbored IDH1 and 51 (18%) IDH2 mutations. IDH1/2 mutations were significantly associated with WHO PS >2 (p < 0.001) and non-complex karyotype (p = 0.021) when compared to IDH1/2-WT. Furthermore, patients with IDH1 mutations were more frequently NPM1-mutated (p = 0.007) and had a higher platelet count (p = 0.036). At relapse, IDH1/2 mutations were detected in 6 (25%) patients. As per the outcome, 60.5% of IDH1/2-mutated patients achieved complete remission; overall survival and event-free survival at 2 years were 44.5% and 36.1%, respectively: these rates were similar to IDH1/2-WT. In IDH1/2-mutated patients, high WBC proved to be an independent prognostic factor for survival. In conclusion, the GIMEMA AML1516 confirms that IDH1/2 mutations are frequently detected at diagnosis and underlines the importance of recognizing IDH1/2-mutated cases up-front to offer the most appropriate therapeutic strategy, given the availability of IDH1/2 inhibitors.
ABSTRACT
Invasive fungal diseases (IFDs) are a leading cause of infection-related-mortality after allogeneic hematopoietic stem cell transplantation (HSCT). In this prospective pilot study, we investigated the use of bedside lung ultrasound (US) in IFD management. Ten consecutive hematological patients, who developed pulmonary IFD after HSCT, were included in the study. Standard computed tomography scan and lung US were performed at IFD diagnosis and 10 days after antifungal treatment. The lung US demonstrated a high sensitivity in the detection of lung lesions at IFD diagnosis and in the follow-up examinations. It is of potential clinical relevance for IFD management in hematological patients.
