Background: The ASPIRE (NCT01080391) phase 3 trial showed the efficacy of carfilzomib, lenalidomide and dexamethasone (KRd) triplet for relapse and refractory multiple myeloma (RRMM). However, little is known about safety and efficacy of KRd outside a clinical trial context. Methods: Herein we report real life results of KRd given to 130 RRMM patients from 12 Sicilian Centers. Results: Median age was 62 years; patients had received a median of two previous lines of treatment (range 1–10) and 52% were refractory to previous treatment. Median number of KRd cycles was 12 (2–29), with a mean duration of treatment of 12 months; 21 patients had received at least 18 cycles. Overall response rate was 61%, including 18% complete response. Median PFS was 22.9 months, median OS was not reached. Creatinine clearance >30 mL/min, quality of the best achieved response and standard Fluorescence In Situ Hybridization (FISH) risk were independent predictors of favorable outcome. Patients who received the full-dosage of carfilzomib in the first two cycles had a better outcome. Conclusions: KRd was effective and well tolerated and in a considerable proportion of patients, therapy continued beyond the 18th cycle. The finding of a better outcome in patients with the higher cumulative dose of carfilzomib in the first two cycle encourages to maintain the maximum tolerated dose.

Transplanted patients with a history of invasive fungal infection (IFI) are at high risk of developing relapse and fatal complications. Eighteen patients affected by hematological malignancies and a previous IFI were submitted to allogeneic stem cell transplantation, using Caspofungin as a secondary prophylaxis. Patients had a probable or proven fungal infection and 16 had a pulmonary localization. No side effects were recorded during treatment with Caspofungin. Compared to pre-transplant evaluation, stability or improvement of the previous IFI was observed in 16 of the 18 patients at day 30, in 13 of the 15 evaluable patients at day 180 and in 11 of the 11 evaluable patients at day 360 post transplant. In particular, all the six patients with a proven fungal infection were alive, with a stable or improved IFI after 1 year from transplant. At a maximum follow-up of 31 months, eight patients died for disease progression or transplant-related complications, but only two had evidence of fungal progression. Secondary prophylaxis with Caspofungin may represent a suitable approach to limit IFI relapse or progression, allowing patients with hematological malignancies to adhere to the planned therapeutic program

Defibrotide has been proposed as preventive treatment of Veno Occlusive Disease (VOD), data on its use are, however, limited and its effectiveness not yet demonstrated. We have administered Defibrotide as prevention of VOD in pts treated with HSC transplantation because of haematological malignancies, all patients were at high VOD risk because of hyper-ferritinemia (>800 ng/ml) or because not in CR of their underlying disease at time of transplant or being overweight (Actual BW>20% of Ideal BW) or because Hepatitis virus B or C sero-positive. 120 pts were treated with Defibrotide, 77 pts received allogeneic HSC tx and 43 autologous HSC tx, 105 received a myeloablative conditioning (55 pts it was based on busulfan) and 15 pts received a RIC. 48% of patients were affected with Acute leukemia, 23% with Lymphomas, 17% with Multiple Myeloma, 12% by other malignancies. Defibrotide was administered i.v. at dosage of 600 mg/d. from the day of conditioning was started to day +25 together with heparin at low dose (100 IU/Kg c.i.). RESULTS: after prophylaxis with Defibrotide a bilirubin value above 2.5 mg/dl during the first 30 days was observed in 16/120 pts (13%), 7/120 pts (5%) reached Seattle’s VOD criteria but had spontaneous resolution of liver toxicity, only 1 patient (0.8%) had a severe VOD and MOF. Overall survival at 3 years was 60% and it was 54% in allo-transplanted patients. We compared results with those obtained in a group of 78 pts treated by allogeneic or autologous transplants and who received low dose heparin only and not Defibrotide because they were considered at low risk of VOD. Percentage of pts who developed a bilirubin level > 2.5 mg/dl (p=0.12) and percentage of patients that reached criteria for VOD were not different (p= 0.08) in these two groups, numbers of red blood cell transfusions were comparable (p=0.07). When all the 198 studied patients were analyzed using logistic regression for factors important in the development of a bilirubinemia above 2.5 mg/dl we found to be important: use of MTX as prophylaxis of GVHD (P=0.004; Odds ratio 5,153), allogeneic transplant (P=0.007; Odds ratio 7,127) and baseline value of bilirubin (P=0.02; Odds Ratio 4,690). Conclusions: Use of Defibrotide in prophylaxis of VOD after HSC transplantation is safe and when employed in patients at high risk of VOD, it leads to an incidence of severe VOD below 1% with a frequency of liver toxicity equivalent to that found in patients having low risk features. To conclude on efficacy of Defibrotide in comparison to low dose heparin alone, a large randomised comparison is warranted.

Acute promyelocytic leukemia (APL) is characterized by onset at a young age and a life-threatening hemorrhagic diathesis, which is attributed to a disseminated intravascular coagulation (DIC)-like coagulopathy. The discovery of all-trans-retinoic acid has changed the course of APL treatment by reducing the onset of DIC and inducing a complete and durable remission in more than 90% of patients. The occurrence of APL during pregnancy is not a frequent event, but the management of these patients raises many therapeutic and ethical dilemmas and requires a careful clinical case evaluation of fetal and maternal risk, coagulation status, the parents' wishes, and therapeutic options. Here we describe 3 patients with APL diagnosed during pregnancy. Clinical data and the therapeutic approaches are presented. In the discussion, we analyze clinical decisions and therapeutic options and compare our cases with those found in the literature.
