Article: Third party cord blood transplant boosts autologous hematopoiesis in a case of persistent bone marrow aplasia after double transplant failure for B-thalassemia major.
[show abstract] [hide abstract]
ABSTRACT: A 9-year-old female received an allogeneic stem cell transplant (SCT) from an ABO-incompatible HLA-matched sibling for β-thalassemia major, without achieving a complete donor chimerism. Subsequently, the patient received five donor lymphocyte infusions, without increasing donor chimerism, and autologous SCT. Due to the persistent bone marrow aplasia, the patient received a second allogeneic SCT from the same donor without obtaining any engrafment. After the double transplant failure, we performed an unrelated transplant from a full-matched umbilical cord blood (UCBT) without administering any neither conditioning regimen nor GVHD prophylaxis. Forty days after UCBT, trilinear engraftment was documented. Surprisingly, the hematopoietic reconstitution was related to the re-expansion of the autologous (beta-thalassemic) hematopoietic stem cell, as documented by chimerism studies. At present, 30 months after UCBT, there is stable hematopoietic autologous reconstitution. This is the first description of the restoration of autologous hematopoiesis obtained with UCBT in a thalassemia-major patient after a double transplant failure.Mediterranean Journal of Hematology and Infectious Diseases 01/2013; 5(1):e2013029. -
Article: Autologous stem cell transplantation for aggressive lymphomas.
[show abstract] [hide abstract]
ABSTRACT: The role of high-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) in the treatment armamentarium of aggressive B- and T-cell non-Hodgkin lymphoma (NHL) is still a matter of debate. In the pre-Rituximab era, the PARMA study demonstrated the superiority of HDT/ASCT over conventional salvage chemotherapy in chemosensitive, relapsed patients. Subsequently, HDT/ASCT has become a standard approach for relapsed NHL. With the advent of Rituximab in the landscape of NHL, transplantation as part of first-line therapy has been challenged. However, no benefit in terms of disease-free or overall survival of HDT/ASCT over standard therapy was shown when Rituximab was added to both arms. Moreover, the superiority of HDT/ASCT over conventional salvage therapy in patients relapsing from first-line therapy including Rituximab was not confirmed. From these disappointing results, novel strategies, which can enhance the anti-lymphoma effect, at the same time reducing toxicity have been developed, with the aim of improving the outcome of HDT/ASCT in aggressive NHL. In T-cell lymphoma, few publications demonstrated that consolidation of complete remission with HDT/ASCT is safe and feasible. However, up to one-third of patients may never receive transplant, mostly due to progressive disease, and relapse still remains a major concern even after transplant.Mediterranean Journal of Hematology and Infectious Diseases 01/2012; 4(1):e2012075. -
Article: R-COMP 21 for frail elderly patients with aggressive B-cell non-Hodgkin lymphoma: a pilot study.
[show abstract] [hide abstract]
ABSTRACT: We evaluated the toxicity and efficacy of nonpegylated liposomal doxorubicin (Myocet) when substituted for conventional doxorubicin in the CHOP-21 regimen in the treatment of frail elderly patients with aggressive non-Hodgkin lymphoma. Twenty frail patients (median age, 73 years), as defined by Balducci et al., with diffuse large B cell or grade IIIb follicular lymphoma, either at diagnosis (15 patients) or relapsed (five patients), were prospectively enrolled. Nine out of 20 (45%) had a World Health Organisation (WHO) performance status > or =2. Fifteen out of 20 patients (75%) had an International Prognostic Index (IPI) score > or =3. Thirteen out of 20 (65%) evaluable patients obtained a complete response. Five additional patients (25%) achieved a partial response. With a median follow-up of 24 months (range 18-27), 15/18 responding patients (83%) are alive and disease free, as well as 3/18 are alive with active disease. Toxicity was mainly hematological with grade 3/4 neutropenia in 26% of cycles and febrile neutropenia in 5%. However, 3/20 patients presented a grade III-IV WHO toxicity (one fatal pulmonary embolism, one congestive, and one ischemic heart failure) while receiving R-COMP chemotherapy. In conclusion, R-COMP-21 is an effective regimen with promising response rates for frail and elderly patients with aggressive non-Hodgkin lymphoma.Leukemia & lymphoma 07/2008; 49(6):1081-6. · 2.40 Impact Factor -
Article: An observational study of once weekly intravenous ganciclovir as CMV prophylaxis in heavily pre-treated chronic lymphocytic leukemia patients receiving subcutaneous alemtuzumab.
[show abstract] [hide abstract]
ABSTRACT: Fifteen consecutive resistant/relapsed chronic lymphocytic leukemia (CLL) patients (median age: 65 years) received alemtuzumab for 16 consecutive weeks. All patients had negative CMV anti genemia at baseline. Five patients received oral acyclovir 800 mg twice a day for CMV prophylaxis and 10 patients got intravenous (iv) ganciclovir 7.5 mg/kg once a week. A total of five CMV reactivations occurred, four in the acyclovir and one in the ganciclovir prophylaxis group. Alemtuzumab was then discontinued and all patients were treated with iv ganciclovir 7.5 mg/kg per day. All patients achieved negative CMV anti genemia after a median of 15 days of therapy. Weekly iv ganciclovir prophylaxis and alemtuzumab treatment were then restarted without any further CMV reactivations. In conclusion, weekly iv ganciclovir appears feasible and effective in preventing CMV reactivation and disease in this setting of high-risk immunocompromised patients, allowing an easier management of a therapy otherwise difficult to be routinely used.Leukemia and Lymphoma 01/2007; 47(12):2542-6. · 2.58 Impact Factor -
Article: Long-term experience with low-dose interferon-alpha and PUVA in the management of early mycosis fungoides.
[show abstract] [hide abstract]
ABSTRACT: Combined high-dose Interferon-alpha and psoralen plus ultraviolet A irradiation (PUVA) have been reported to be effective in the treatment of early mycosis fungoides (MF); however, our study is the first controlled prospective study in the literature exploring the activity and tolerability of the combination with low dosages and evaluating further clinical outcome of early-MF patients. We carried out a multicentric prospective Phase II clinical study on 89 patients with early-stage IA to IIA MF treated for 14 months with low-dose IFN-alpha2b (6-18 MU/wk) and PUVA. Treatment success was analysed in terms of freedom from treatment failure. Complete remission (CR) was achieved in 84% and an overall response rate in 98% of cases: six-month CR was associated with a non-confluent skin infiltrate at histology (P = 0.044) and 14-month CR with high epidermal CD1a+ dendritic-cell density (P = 0.030). The combination protocol was successfully tolerated and the most common reason of 'failure' was related to relapse and not to toxicity. Sustained remissions were achieved in 20% of patients. High CD8+ lymphoid T-cell density was associated with a lower relapse rate (P = 0.002). We think that our combination therapy can be considered an alternative approach compared with other modalities. Good immunological host surveillance in the skin lesions seems to be an optimal basis for the therapeutic success.European Journal Of Haematology 09/2005; 75(2):136-45. · 2.61 Impact Factor -

Article: Mini-ICE effectively mobilises peripheral blood stem cells after fludarabine-based regimens in acute myeloid leukaemia.
[show abstract] [hide abstract]
ABSTRACT: Fludarabine-based cycles severely impair mobilisation and collection of peripheral blood stem cells (PBSC) in acute myeloid leukaemia (AML). In an effort of reversing this side-effect, we studied the action on mobilisation and collection of PBSC of a low-dose regimen: 5-d Mini-ICE (oral idarubicin and etoposide; subcutaneous cytosine arabinoside) administered after fludarabine-based regimens in seven adult AML patients. Leukapheresis were started when the CD34+ cell count was more than 10/microL. The median number of harvested CD34+ cells was 8.1 x 10(6)/kg (range 3.08-15.2). All the patients were successfully submitted to PBSC transplantation. Median times to neutrophil and platelet recovery were rapid with a normal transfusional support. We suggest that the Mini-ICE programme is feasible, well tolerated and effective in terms of PBSC mobilisation and collection in low-yield AML patients previously treated with fludarabine. It is well known that a negative effect on stem cell mobilisation and harvest is observed not only after fludarabine administration in AML or low-grade lymphomas, but also after cycles based on different agents, such as thalidomide in multiple myeloma. This preliminary experience, if confirmed on larger series and/or other haematological malignancies, could open new opportunities to perform autologous PBSC transplantation in heavily pretreated cases, allowing a full source of therapeutic options before the start of the mobilisation process.European Journal Of Haematology 05/2005; 74(4):277-81. · 2.61 Impact Factor -
Article: Low-dose thalidomide ameliorates cytopenias and splenomegaly in myelofibrosis with myeloid metaplasia: a phase II trial.
[show abstract] [hide abstract]
ABSTRACT: A phase II dose-escalation trial was conducted to ascertain low-dose thalidomide safety and response in patients with advanced myelofibrosis with myeloid metaplasia (MMM). Thalidomide was administered together with current therapy to 63 patients, starting at 50 mg daily and increasing to 400 mg as tolerated. Half of the patients sustained daily doses more than 100 mg and the drop-out rate was 51% at 6 months: the drop-out rate was lower in patients with high baseline fatigue score. At efficacy analysis, anemia was ameliorated in 22% of the patients and transfusions were eliminated in 39% of transfusion-dependent patients. Platelet count increased by 50 x 10(9)/L or more in 22% of patients with an initial count lower than 100 x 10(9)/L. Splenomegaly decreased by more than 50% of the initial size in 19% of patients. Reduction of an overall disease severity score occurred in 31% of patients and was associated with a significant reduction of fatigue. Disease severity amelioration was independently predicted by a high baseline myeloproliferative index (ie, large splenomegaly, thrombocytosis, or leukocytosis). Low-dose thalidomide displays an acceptable toxicity profile and provides an objective and subjective advantage to a relevant portion of MMM patients.Journal of Clinical Oncology 03/2004; 22(3):424-31. · 18.37 Impact Factor
