Monoclonal Gammopathy of Renal Significance: Clinical and Histological Efficacy of a Bortezomib-Based Regimen.

Front Med (Lausanne) 2020 16;7:587345. Epub 2020 Dec 16.

Nephrology and Dialysis Unit, San Giovanni Bosco Hospital, Turin, Italy.

Monoclonal Gammopathy of Renal Significance (MGRS) is a group of heterogeneous disorders characterized by renal dysfunction secondary to the production of a monoclonal immunoglobulin by a nonmalignant B cell or plasma cell clone. We report the clinical and histological outcomes of two patients with biopsy-proven MGRS: one patient showed membranoproliferative glomerulonephritis with monoclonal k-light chain and C3 deposits, the second patient showed immunotactoid glomerulopathy. Both patients were treated with a 9-month chemotherapy protocol including bortezomib, cyclophosphamide, and dexamethasone. Renal biospy was repeated after 1 year. The estimated glomerular filtration rate (eGFR) increased from 22.5 (baseline) to 40 ml/min per 1.73 m2 after 12 months, then to 51.5 ml/min per 1.73 m2 after 24 months; proteinuria decreased from 4.85 (baseline) to 0.17 g/day after 12 months, then to 0.14 g/day after 24 months. Repeat renal biopsies showed a dramatic improvement of the glomerular proliferative lesions and near complete disappearance of the immune deposits. A bortezomib-based treatment proved very effective and was well-tolerated in the two patients presenting with clinically and histologically aggressive MGRS.

Antiemetic prophylaxis in patients undergoing hematopoietic stem cell transplantation: a multicenter survey of the Gruppo Italiano Trapianto Midollo Osseo (GITMO) transplant programs.

Ann Hematol 2020 Apr 8;99(4):867-875. Epub 2020 Feb 8.

SODc Terapie Cellulari e Medicina Trasfusionale, AOU Careggi, Florence, Italy.

A survey within hematopoietic stem cell transplant (HSCT) centers of the Gruppo Italiano Trapianto Midollo Osseo (GITMO) was performed in order to describe current antiemetic prophylaxis in patients undergoing HSCT. The multicenter survey was performed by a questionnaire, covering the main areas on chemotherapy-induced nausea and vomiting (CINV): antiemetic prophylaxis guidelines used, antiemetic prophylaxis in different conditioning regimens, and methods of CINV evaluation. The survey was carried out in November 2016, and it was repeated 6 months after the publication of the Multinational Association of Supportive Care in Cancer (MASCC)/European Society for Medical Oncology (ESMO) specific guidelines on antiemetic prophylaxis in HSCT. The results show a remarkable heterogeneity of prophylaxis among the various centers and a significant difference between the guidelines and the clinical practice. In the main conditioning regimens, the combination of a serotonin receptor antagonist (5-HT-RA) with dexamethasone and neurokin receptor antagonist (NK1-RA), as recommended by MASCC/ESMO guidelines, increased from 0 to 15% (before the publication of the guidelines) to 9-30% (after the publication of the guidelines). This study shows a lack of compliance with specific antiemetic guidelines, resulting mainly in under-prophylaxis. Concerted strategies are required to improve the current CINV prophylaxis, to draft shared common guidelines, and to increase the knowledge and the adherence to the current recommendations for CINV prophylaxis in the specific field of HSCT.

Predicting failure of hematopoietic stem cell mobilization before it starts: the predicted poor mobilizer (pPM) score.

Bone Marrow Transplant 2018 04 12;53(4):461-473. Epub 2018 Jan 12.

Hematology and Stem Cell Transplant, Ravenna Hospital, Ravenna, Italy.

Predicting mobilization failure before it starts may enable patient-tailored strategies. Although consensus criteria for predicted PM (pPM) are available, their predictive performance has never been measured on real data. We retrospectively collected and analyzed 1318 mobilization procedures performed for MM and lymphoma patients in the plerixafor era. In our sample, 180/1318 (13.7%) were PM. The score resulting from published pPM criteria had sufficient performance for predicting PM, as measured by AUC (0.67, 95%CI: 0.63-0.72). We developed a new prediction model from multivariate analysis whose score (pPM-score) resulted in better AUC (0.80, 95%CI: 0.76-0.84, p < 0001). pPM-score included as risk factors: increasing age, diagnosis of NHL, positive bone marrow biopsy or cytopenias before mobilization, previous mobilization failure, priming strategy with G-CSF alone, or without upfront plerixafor. A simplified version of pPM-score was categorized using a cut-off to maximize positive likelihood ratio (15.7, 95%CI: 9.9-24.8); specificity was 98% (95%CI: 97-98.7%), sensitivity 31.7% (95%CI: 24.9-39%); positive predictive value in our sample was 71.3% (95%CI: 60-80.8%). Simplified pPM-score can "rule in" patients at very high risk for PM before starting mobilization, allowing changes in clinical management, such as choice of alternative priming strategies, to avoid highly likely mobilization failure.

Impact of New Drugs on the Long-Term Follow-Up of Upfront Tandem Autograft-Allograft in Multiple Myeloma.

Biol Blood Marrow Transplant 2018 01 4;24(1):189-193. Epub 2017 Oct 4.

Department of Molecular Biotechnology and Health Sciences, University of Torino, Torino, Italy; Department of Oncology, A.O.U. Città della Salute e della Scienza di Torino, Torino, Italy.

Before the introduction of "new drugs," we designed a trial in which 162 newly diagnosed myeloma patients were biologically randomized to receive either an autologous stem cell transplant (auto-SCT) followed by a nonmyeloablative allogeneic stem cell transplant (allo-SCT) or a double auto-SCT. Fifty-eight patients in the allo-SCT arm and 46 in the double auto-SCT arm completed the assigned treatment. At a median follow-up of 12.3 years from allo-SCT and 12.1 years from second auto-SCT, median overall survival (OS) was 11.4 in the allo-SCT arm and 3.9 years in the auto-SCT -arm (P = .007), whereas event-free survival was 3.6 and 1.5 years (P < .001), respectively. A subset of allo-SCT patients showed persistent molecular remission. Two-year cumulative incidence of chronic graft-versus-host disease was 67.2%. At 5 years, 39% of these patients were alive, disease-free, and off immunosuppression; 36.6% had relapsed and 12.2% were still on immunosuppression. Thirty-three of 58 patients (allo-SCT arm) and 39 of 46 (auto-SCT arm) relapsed at least once and were rescued with new drugs. In the allo-SCT arm, 2 patients in biochemical relapse did not reach clinical criteria for treatment. Overall 28 (90%) were treated with new drugs and 14 (45%) received donor lymphocyte infusions (DLIs). In 28 of 31 patients (90%) DLIs were given with new drugs. Median OS from first relapse was 7.5 years in the allo-SCT arm and 2 years in the auto-SCT arm (P = .01). Patients who received DLI showed significantly longer OS (hazard ratio, .38; P = .042) as compared with auto-SCT patients. This difference was slightly lower when only allo-SCT patients who did not receive DLIs were considered (hazard ratio, .56; P = .154). In summary, long-term disease-free survival and survival outcomes after treating relapse with new drugs with or without DLIs were better in allo-SCT patients.

Purpose To compare a reduced-intensity conditioning regimen (RIC) with a myeloablative conditioning regimen (MAC) before allogeneic transplantation in patients with myelodysplastic syndrome (MDS) within a randomized trial. Patients and Methods Within the European Society of Blood and Marrow Transplantation, we conducted a prospective, multicenter, open-label, randomized phase III trial that compared a busulfan-based RIC with MAC in patients with MDS or secondary acute myeloid leukemia. A total of 129 patients were enrolled from 18 centers. Patients were randomly assigned in a 1:1 ratio and were stratified according to donor, age, and blast count. Results Engraftment was comparable between both groups. The CI of acute graft-versus-host disease II to IV was 32.3% after RIC and 37.5% after MAC ( P = .35). The CI of chronic graft-versus-host disease was 61.6% after RIC and 64.7% after MAC ( P = .76). The CI of nonrelapse mortality after 1 year was 17% (95% CI, 8% to 26%) after RIC and 25% (95% CI, 15% to 36%) after MAC ( P = .29). The CI of relapse at 2 years was 17% (95% CI, 8% to 26%) after RIC and 15% (95% CI, 6% to 24%) after MAC ( P = .6), which resulted in a 2-year relapse-free survival and overall survival of 62% (95% CI, 50% to 74%) and 76% (95% CI, 66% to 87%), respectively, after RIC, and 58% (95% CI, 46% to 71%) and 63% (95% CI, 51% to 75%), respectively, after MAC ( P = .58 and P = .08, respectively). Conclusion This prospective, randomized trial of the European Society of Blood and Marrow Transplantation provides evidence that RIC resulted in at least a 2-year relapse-free survival and overall survival similar to MAC in patients with MDS or secondary acute myeloid leukemia.

Allogeneic Stem Cell Transplantation for Relapsed/Refractory B Cell Lymphomas: Results of a Multicenter Phase II Prospective Trial including Rituximab in the Reduced-Intensity Conditioning Regimen.

Biol Blood Marrow Transplant 2017 Jul 5;23(7):1102-1109. Epub 2017 Apr 5.

Division of Hematology, Fondazione IRCCS Istituto Nazionale dei Tumori, Milano, Italy; Dept of Oncology, University of Milan, Milan, Italy.

The treatment of patients with refractory/relapsed B cell non-Hodgkin lymphoma (NHL) is evolving because of the availability of novel drugs. Allogeneic stem cell transplantation (alloSCT) can be curative, but its morbidity and mortality remain a matter of concern. We conducted a multicenter prospective phase II trial to evaluate the benefit of including only 1 dose of rituximab in the conditioning regimen before alloSCT. The primary endpoint was progression-free survival. The study enrolled 121 patients with relapsed/refractory B cell lymphomas. The conditioning regimen consisted of thiotepa, cyclophosphamide, fludarabine, and rituximab (500 mg/m). Rabbit antithymocyte globulin was administered only in case of unrelated donors. Sixty-seven (55%) and 54 (45%) patients received grafts from related and unrelated donors, respectively. The crude cumulative incidence (CCI) of nonrelapse mortality (NRM) was 21% at 3 years. The CCIs of chronic graft-verus-host disease (GVHD) at 3 years were 54% and 31% in recipients of matched sibling and unrelated grafts, respectively. At a median follow-up of 41 months, the estimated 3-year progression-free and overall survival were 50% and 61%, respectively. Long-term outcome was also evaluated with the composite endpoint of GVHD-free and relapse-free survival (GRFS). This is the first work evaluating the GRFS in a prospective trial of lymphoma patients: the 1-year and 3-year GRFS were 40% and 34%, respectively. AlloSCT can cure a fraction of patients with rather low NRM and an encouraging PFS and GRFS.

A Single-Center Pilot Prospective Study of Topical Application of Platelet-Derived Eye Drops for Patients with Ocular Chronic Graft-versus-Host Disease.

Biol Blood Marrow Transplant 2016 09 4;22(9):1664-1670. Epub 2016 Jun 4.

Hematology Department, SS Antonio & Biagio and C. Arrigo Hospital, Alessandria, Italy.

Ocular involvement of chronic graft-versus-host disease (cGVHD) is a complication that occurs in up to 60% of patients after allogeneic hematopoietic stem cell transplantation. Conventional therapeutic options include medical and surgical procedures that are administered depending on the severity of the condition, but most of them have provided unsatisfactory results and, to date, there is no consensus about treatment. We considered that topical application of a platelet lysate, administered as eye drops, might be considered an alternative worthwhile of investigation to treat ocular surface disorders in patients suffering from cGVHD. Therefore, we conducted a single-center prospective pilot study to assess the efficacy and safety of using eye drops made from reconstituted lysed platelet concentrate. Twenty-six patients with ocular cGVHD were eligible for the study; all but 2 completed their scheduled 1-year treatment and complied with the hematologic and ophthalmic regimen. At their first assessment interviews, after 30 days of treatment, 91% of patients reported an improvement in their symptoms and for 32%, substantive objective differences were measured. Remission of corneal damage was seen for 86% of our cohort, and improved National Institutes of Health scores for 73%, of whom 8% achieved the best score of 0 (ie, non-dry eye). Similar results were seen at later time points. Comparing outcomes for our patient cohort to those determined retrospectively for patients in our institutional database revealed a 5-year overall survival (OS) of 65%. This OS is comparable to patients with limited cGVHD (75%) and is superior to that of patients with nonocular extensive cGVHD or without cGVHD (30% and 59%, respectively) (P = .013). Our results suggest that platelet-derived eye drops are a safe, practical, and well-tolerated therapeutic option that offers substantial benefits for most patients affected by ocular cGVHD at onset. The favorable OS of our patient cohort suggests that this topical therapy, rather than systemic immunosuppression, may be the treatment of choice.

Background: Chronic graft-versus-host disease (GVHD) is the leading cause of later illness and death after allogeneic hematopoietic stem-cell transplantation. We hypothesized that the inclusion of antihuman T-lymphocyte immune globulin (ATG) in a myeloablative conditioning regimen for patients with acute leukemia would result in a significant reduction in chronic GVHD 2 years after allogeneic peripheral-blood stem-cell transplantation from an HLA-identical sibling.

Methods: We conducted a prospective, multicenter, open-label, randomized phase 3 study of ATG as part of a conditioning regimen. A total of 168 patients were enrolled at 27 centers. Patients were randomly assigned in a 1:1 ratio to receive ATG or not receive ATG, with stratification according to center and risk of disease.

Results: After a median follow-up of 24 months, the cumulative incidence of chronic GVHD was 32.2% (95% confidence interval [CI], 22.1 to 46.7) in the ATG group and 68.7% (95% CI, 58.4 to 80.7) in the non-ATG group (P<0.001). The rate of 2-year relapse-free survival was similar in the ATG group and the non-ATG group (59.4% [95% CI, 47.8 to 69.2] and 64.6% [95% CI, 50.9 to 75.3], respectively; P=0.21), as was the rate of overall survival (74.1% [95% CI, 62.7 to 82.5] and 77.9% [95% CI, 66.1 to 86.1], respectively; P=0.46). There were no significant between-group differences in the rates of relapse, infectious complications, acute GVHD, or adverse events. The rate of a composite end point of chronic GVHD-free and relapse-free survival at 2 years was significantly higher in the ATG group than in the non-ATG group (36.6% vs. 16.8%, P=0.005).

Conclusions: The inclusion of ATG resulted in a significantly lower rate of chronic GVHD after allogeneic transplantation than the rate without ATG. The survival rate was similar in the two groups, but the rate of a composite end point of chronic GVHD-free survival and relapse-free survival was higher with ATG.

Busulfan plus cyclophosphamide versus busulfan plus fludarabine as a preparative regimen for allogeneic haemopoietic stem-cell transplantation in patients with acute myeloid leukaemia: an open-label, multicentre, randomised, phase 3 trial.

Lancet Oncol 2015 Nov 28;16(15):1525-1536. Epub 2015 Sep 28.

Hematology, Azienda Ospedaliera S Croce e Carle, Cuneo, Italy.

Background: The standard busulfan-cyclophosphamide myeloablative conditioning regimen is associated with substantial non-relapse mortality in patients older than 40 years with acute myeloid leukaemia who are undergoing allogeneic stem-cell transplantation. Because the combination of busulfan plus fludarabine has been proposed to reduce non-relapse mortality, we aimed to compare this treatment with busulfan plus cyclophosphamide as a preparative regimen in these patients.

Methods: We did an open-label, multicentre, randomised, phase 3 trial for patients with acute myeloid leukaemia at 25 hospital transplant centres in Italy and one in Israel. Eligible patients were aged 40-65 years, had an Eastern Cooperative Oncology Group performance status less than 3, and were in complete remission. Patients were randomly assigned 1:1 to receive intravenous busulfan plus cyclophosphamide or busulfan plus fludarabine. Treatment allocations were not masked to investigators or patients. Randomisation was done centrally via a dedicated web-based system using remote data entry, with patients stratified by donor type and complete remission status. Patients allocated to busulfan plus cyclophosphamide received intravenous busulfan 0·8 mg/kg four times per day during 2 h infusions for four consecutive days (16 doses from days -9 through -6; total dose 12·8 mg/kg) and cyclophosphamide at 60 mg/kg per day for two consecutive days (on days -4 and -3; total dose 120 mg/kg). Patients allocated to busulfan plus fludarabine received the same dose of intravenous busulfan (from days -6 through -3) and fludarabine at 40 mg/m(2) per day for four consecutive days (from days -6 through -3; total dose 160 mg/m(2)). The primary endpoint was 1-year non-relapse mortality, which was assessed on an intention-to-treat basis; safety outcomes were assessed in the per-protocol population. This trial has been completed and is registered with ClinicalTrials.gov, number NCT01191957.

Findings: Between Jan 3, 2008, and Dec 20, 2012, we enrolled and randomly assigned 252 patients to receive busulfan plus cyclophosphamide (n=125) or busulfan plus fludarabine (n=127). Median follow-up was 27·5 months (IQR 9·8-44·3). 1-year non-relapse mortality was 17·2% (95% CI 11·6-25·4) in the busulfan plus cyclophosphamide group and 7·9% (4·3-14·3) in the busulfan plus fludarabine group (Gray's test p=0·026). The most frequently reported grade 3 or higher adverse events were gastrointestinal events (28 [23%] of 121 patients in the busulfan plus cyclophosphamide group and 26 [21%] of 124 patients in the busulfan plus fludarabine group) and infections (21 [17%] patients in the busulfan plus cyclophosphamide group and 13 [10%] patients in the busulfan plus fludarabine group had at least one such event).

Interpretation: In older patients with acute myeloid leukaemia, the myeloablative busulfan plus fludarabine conditioning regimen is associated with lower transplant-related mortality than busulfan plus cyclophosphamide, but retains potent antileukaemic activity. Accordingly, this regimen should be regarded as standard of care during the planning of allogeneic transplants for such patients.

The use of ATG abrogates the antileukemic effect of cytomegalovirus reactivation in patients with acute myeloid leukemia receiving grafts from unrelated donors.

Am J Hematol 2015 Jun 1;90(6):E117-21. Epub 2015 Apr 1.

Department of Oncology and Hematology, Stem Cell Transplant Center, AOU Città Della Salute E Della Scienza, Turin, Italy.

Several studies provided evidence of a consistent antileukemic effect induced by cytomegalovirus (CMV) replication in acute myeloid leukemia (AML) patients receiving allogeneic hematopoietic stem cell transplantation (HSCT), however the use of antithymocyte globulin (ATG) as graft-versus-host disease prophylaxis, may potentially abrogate the protective effect of CMV infection. To address this issue, we retrospectively analyzed the risk of relapse in a cohort of 101 patients with AML who received grafts from an unrelated donor after a conditioning regimen including ATG. The cumulative incidence of CMV reactivation, evaluated by RT qPCR, was 59% at 12 months, and 93% of CMV reactivations occurred within the first 100 days post HSCT. The 5-year cumulative incidence of relapse in patients with CMV reactivation was 29% compared with 37% for patients without CMV reactivation, and the only factor associated with a reduced 5-year cumulative incidence of relapse was the disease status at HSCT (P < 0.001). In the multivariable model adverse cytogenetics (HR 2.42, 95% CI 1.02-5.72; P = 0.044) and acute GVHD (HR 3.36, 95% CI 1.32-8.54; P =  0.011) were independent risk factors for reducing overall survival (OS), while the presence of chronic GVHD was associated with a better OS (HR 0.37, 95% CI 0.15-0.89; P = 0.027). CMV replication was not an independent risk factor for OS (HR 1.06, 95% CI 0.07-15.75; P = 0.965). In Conclusion, the results of present study suggest that relapse prevention in patients with AML receiving T-cell depleted HSCT using ATG do not benefit from CMV reactivation.

Successful HLA haploidentical myeloablative stem cell transplantation for aggressive hepatosplenic alpha/beta (αβ) T-cell lymphoma.

Leuk Res Rep 2014 28;3(2):90-3. Epub 2014 Oct 28.

Hematology and Marrow Transplant, A.O. SS Antonio e Biagio e Cesare Arrigo, Alessandria, Italy.

Hepatosplenic T cell lymphoma (HSTCL) is a type of hematologic neoplasia with a poor prognosis and a high frequency of refractoriness to conventional chemotherapy. The results obtained by high dose chemotherapy followed by autologous stem cells transplantation seem to be a more effective option but still unsatisfactory. Also the role of allogeneic stem cell transplantation is still unclear, although the few cases reported on the literature would seem to show good results in overall survival rates. In this paper, we reported the patient׳s medical history affected by a αβ variant of hepatosplenic T cell successfully rescued with a haploidentical transplant.

Allogeneic stem cell transplant for adults with myelodysplastic syndromes: relevance of pre-transplant disease status.

Leuk Lymphoma 2014 Apr 18;55(4):863-9. Epub 2013 Jul 18.

Bone Marrow Transplant Center.

The aim of the present study was to investigate the outcome of 94 adult patients with myelodysplasia (MDS) who received an allogeneic stem cell transplant between January 1995 and September 2010 in two Italian hematology centers. At the time of transplant, 53 patients (56%) had relapsed/refractory disease. The cumulative incidence of grades II-IV acute graft-versus-host disease (GVHD) and chronic GVHD was 33% (95% confidence interval [CI] 21-45%) and 78% (95% CI 66-90%), respectively. The cumulative incidence of transplant-related mortality (TRM) at 100 days was 13% (95% CI 6-21%). The 2-year progression free survival (PFS) and overall survival (OS) were 41% (95% CI 31-51%) and 49% (95% CI 38-59%), respectively. On multivariate analysis, advanced disease stage at transplant was the major independent variable associated with an inferior 2-year PFS (HR 3.66, 95% CI 1.98-6.76) and OS (HR 3.68, 95% CI 1.95-6.93). Use of an alternative donor was an independent variable associated with TRM (HR 3.18, 95% CI 1.31-7.72). In conclusion, our data suggest that disease status at the time of transplant is the major predictor for improved PFS and OS, and treatments required to reach this goal may have value in leading to an improved outcome.

Epstein-Barr virus reactivation in allogeneic stem cell transplantation is highly related to cytomegalovirus reactivation.

Clin Transplant 2013 Jul-Aug;27(4):E491-7. Epub 2013 Jun 19.

Department of Hematology, SS Antonio e Biagio Hospital, Alessandria, Italy.

Monitoring of Epstein-Barr virus (EBV) load and pre-emptive rituximab is an appropriate approach to prevent post-transplant lymphoproliferative disease (PTLD) occurring after hematopoietic stem cell transplantation (HSCT). This pre-emptive approach, based on EBV-DNA monitoring through a quantitative polymerase chain reaction, was applied to 101 consecutive patients who underwent allo HSCT at our Institute (median age 50). A single infusion of rituximab was administered to 11 of 16 patients who were at high risk for progression to PTLD, defined as a DNA value >10 000 copies/mL. All patients cleared EBV DNAemia, without any recurrences. Main factors significantly associated with high risk for PTLD were as follows: (i) unrelated vs. sibling (26% vs. 7%; p = 0.011); (ii) T-cell depletion (29% vs. 6%; p = 0.001); (iii) graft versus host disease (GVHD; 30% vs. 7%; p = 0.002); and (iv) cytomegalovirus (CMV) reactivation (29% vs. 4%; p = 0.001). Multivariate analysis showed that CMV reactivation was the only independent variable associated with EBV reactivation. We conclude that: (i) a single infusion of rituximab is able to prevent the risk of progression into EBV-related PTLD; and (ii) CMV reactivation is strongly associated with EBV reactivation; therefore, an intensive EBV monitoring strategy could be advisable only in case of CMV reactivation.

Telomere loss in Philadelphia-negative hematopoiesis after successful treatment of chronic myeloid leukemia: evidence for premature aging of the myeloid compartment.

Mech Ageing Dev 2012 Jul 9;133(7):479-88. Epub 2012 Jun 9.

Division of Hematology, University of Turin, A.O.U. San Giovanni Battista, Turin, Italy.

Telomere shortening, a well-known marker of aging and cellular stress, occurs under several conditions in the hematopoietic compartment, including aplastic anemia and following iatrogenic noxae. We decided to verify whether pathological telomere erosion also arises in restored Philadelphia-negative (Ph-negative) hematopoiesis following successful treatment of chronic myeloid leukemia (CML). Eighty-one CML patients in complete cytogenetic remission were compared to 76 age-matched healthy subjects. Myeloid cells of CML patients had shorter telomeres than controls (6521 bp vs 7233 bp, p<0.001). This difference was specific for the myeloid compartment, since it was not observed in lymphoid cells (6774 bp vs 6909 bp, p=0.620). Acquired Ph-negative cytogenetic abnormalities (p=0.010), lack of complete molecular remission (p=0.016) and age (p=0.013) were independent predictors of telomere shortening. Telomere dynamics were assessed over a median follow-up period of 22 months. We documented accelerated non-physiological ongoing telomere shortening in 17/59 CML patients (28%). Patients experiencing grade 2-4 hematological toxicity, during CML remission possessed significantly shorter telomeres compared to those lacking toxicity (p=0.005 for any toxicity, p=0.007 for anemia). CML patients suffer from significant and often ongoing telomere stress resulting in premature and selective aging of the myeloid compartment which might have long-term consequences on function and integrity of Ph-negative hematopoiesis.

Multicenter experience using total lymphoid irradiation and antithymocyte globulin as conditioning for allografting in hematological malignancies.

Biol Blood Marrow Transplant 2012 Oct 5;18(10):1600-7. Epub 2012 Apr 5.

Centro Unico Regionale Trapianti Alberto Neri, A.O. Bianchi-Melacrino-Morelli, Reggio Calabria, Italy.

A non myeloablative conditioning with total lymphoid irradiation (TLI) and antithymocyte globulin (ATG) was shown to protect against graft-versus-host disease (GVHD). To evaluate the effects of TLI-ATG in a multicenter study, 45 heavily pretreated patients, median age 51, with lymphoid (n = 38) and myeloid (n = 7) malignancies were enrolled at 9 centers. Twenty-eight patients (62%) received at least 3 lines of treatment before allografting, and 13 (29%) had refractory/relapsed disease at the time of transplantation. Peripheral blood hematopoietic cells were from HLA identical sibling (n = 30), HLA-matched (n = 9), or 1 antigen HLA-mismatched (n = 6) unrelated donors. A cumulative TLI dose of 8 Gy was administered from day -11 through -1 with ATG at the dose of 1.5 mg/kg/day (from day -11 through -7). GVHD prophylaxis consisted of cyclosporine and mycophenolate mofetil. Donor engraftment was reached in 95% of patients. Grade II to IV acute GVHD (aGVHD) developed in 6 patients (13.3%), and in 2 of these patients, it developed beyond day 100. Incidence of chronic GVHD (cGVHD) was 35.8%. One-year nonrelapse mortality was 9.1%. After a median follow-up of 28 months (range, 3-57 months) from transplantation, median overall survival was not reached, whereas median event-free survival was 20 months. This multicenter experience confirms that TLI-ATG protects against GVHD and maintains graft-vs-tumor effects.

Prevention of bisphosphonates-induced osteonecrosis.

Clin Cases Miner Bone Metab 2007 Jan;4(1):58-61

MD Hematology Division, Azienda Ospedaliera "SS Antonio e Biagio e C. Arrigo", Alessandria, Italy.

The osteonecrosis of the jaw is a new emergent disease, secondary to prolonged use of bisphosphonates. Bisphosphonates are a class of drug used in prevention and cure of bone diseases such as malignancy or bone metabolic diseases. In this article, we have tried to summarize, for patients taking IV or oral bisphosphonates-therapy, the most important informations on the pathogenesis and the risk factors in osteonecrosis of the jaw with particular attention about the preventive policies.

Two new translocations involving the 11q23 region map outside the MLL locus in myeloid leukemias.

Haematologica 2002 Oct;87(10):1014-20

Medicina Interna II, Dipartimento di Scienze Cliniche e Biologiche, Osp. S. Luigi Gonzaga, Orbassano, Italy.

Background And Objectives: In acute leukemias, chromosomal translocations involving the 11q23 band are frequently, but not invariably, associated with MLL gene rearrangement and their finding is associated with a poor prognosis. We observed two new translocations with a breakpoint in the 11q23 region at standard cytogenetic analysis: a previously undescribed t(3;11)(q21;q23) in a 70-year old woman with a fulminating form of AML-M1 and a new translocation t(6;11)(q15;q23) in a 61-year old man with an atypical chronic myelogenous leukemia. In these two patients, involvement of the MLL gene was analyzed by molecular cytogenetic techniques which also allowed a more precise mapping of the breakpoints.

Design And Methods: The MLL gene was analyzed by Southern blot and by fluorescent in situ hybridization (FISH) with a double-color MLL probe. A panel of 11q, 3q and 6q cosmid/YAC probes mapping around the breakpoints was used for breakpoint mapping.

Results: In both patients, FISH analysis and Southern blot showed that the MLL gene was not rearranged; in patient 1, MLL was retained on the 11q+ derivative, whereas in patient 2 it moved to the 6q- chromosome. In the t(3;11) we localized the chromosome 11 breakpoint at 11q23.3, in a region flanked by CP-939H3 and cos1p3, distal to the MLL locus; in the t(6;11) the break occurred at 11q21, in a region flanked by CP-819A5 and CP-829A6, proximal to the MLL locus.

Interpretation And Conclusions: Our cases add two new translocations to the list of chromosomal anomalies involving the long arm of chromosome 11, and show that apparent translocation t(11q23) may involve loci and genes other than MLL. Characterizing the molecular heterogeneity of 11q23 translocations may identify some prognostic significance.
