GITMO REGISTRY STUDY ON ALLOGENEIC TRANSPLANTATION IN PATIENTS AGED OVER 60 FROM 2000 TO 2017. IMPROVEMENTS AND CRITICISMS.

Transplant Cell Ther 2021 Nov 21. Epub 2021 Nov 21.

Unit of Haematology and Stem Cell Transplant Centre, "San Camillo" Hospital, Rome, Italy.

Background: Nowadays, allogeneic stem cell transplantation (Allo-SCT) can be offered to patients up to the age of 70-72 years and represents one of the most effective curative treatments for many hematological malignancies.

Objectives: The primary objective of the study is to collect data from the allo-SCTs performed in Italy from 2000 to 2017 in patients over 60 years of age to evaluate the changes in safety and efficacy outcomes as well as their distribution and characteristics over time.

Study Design: The GITMO AlloEld study (ClinicalTrials.gov: NCT04469985) is a retrospective, analysis of the allo-SCTs performed 30 Italian transplant Centers on older patients (≥ 60 years) from 2000 to 2017 (n=1,996).

Results: For the purpose of analysis, patients were grouped into three time periods: time A: 2000-2005, n=256 (12%); time B: 2006-2011, n=584 (29%); and time C: 2012-2017, n=1156 (59%). After a median follow-up of 5.6 years, the 5-year Non Relapse Mortality (NRM) remained stable (time A: 32.8%; time B: 36.2%; and time C: 35.0%, p = 0.5); the Overall Survival (OS) improved (time A: 28.4%; time B: 31.8%; and time C: 37.3%, p = 0.012); and the Cumulative Incidence of Relapse (CIR) reduced (time A: 45.3%; time B: 38.2%; time C: 30.0%, p < 0.0001). The 2-year incidence of extensive cGVHD reduced significantly (time A: 17.2%; time B: 15.8%; and time C: 12.2%, p = 0.004). Considering times A and B together (2000-2011), the 2-year NRM was positively correlated to the HCT-CI score; patients with HCT-CI of 0, 1 or 2, or ≥3 had rates of NRM of 25.2%, 33.9%, and 36.1%, respectively, (p < 0.001). Meanwhile, after 2012, the HCT-CI score was not significantlly predictive of NRM.

Conclusions: The study shows that the transplant procedure in elderly patients became more effective over time. Relapse incidence remains the major problem and strategies to prevent it are under investigation (e.g. post-transplant maintenance). Today, the selection of patients aged over 60 could be improved by combining HCT-CI and frailty assessments to better predict NRM.

HLA molecules are important for immunoreactivity in allogeneic hematopoietic stem cell transplantation (HSCT). The Gruppo Italiano Trapianto di Cellule Staminali e Terapie Cellulari, Italian Bone Marrow Donor Registry, and Associazione Italiana di Immunogenetica e Biologia dei Trapianti promoted a retrospective observational study to evaluate HLA matching and the impact of allelic HLA mismatching and non-HLA factors on unrelated Italian HSCT outcomes. From 2012 to 2015, 1788 patients were enrolled in the study. The average donor age was 29 years and the average recipient age was 49 years. As a conditioning regimen, 71% of the patients received myeloablative conditioning. For GVHD prophylaxis, 76% received either antithymocyte or anti-T lymphocyte globulin, cyclosporine A, and methotrexate. Peripheral blood was the stem cell source in 80%. The median duration of follow-up was 53 months. Regarding HLA matching, 50% of donor-recipient pairs were 10/10 matched, 38% had 1 mismatch, and 12% had 2 or more mismatches. A total of 302 pairs shared Italian origin. Four-year overall survival (OS), progression-free survival, GVHD-free relapse-free survival, and relapse rates were 49%, 40%, 22%, and 34%, respectively. The 4-year NRM was 27%, and the 100-day cumulative incidence of grade ≥II acute GVHD (aGVHD) was 26%. In multivariate analysis, 9/10 and ≤8/10 HLA allele-matched pairs were associated with worse OS (P = .04 and .007, respectively), NRM (P = .007 and P < .0001, respectively), and grade III-IV aGVHD (P = .0001 and .01, respectively). Moreover, the incidences of grade II-IV aGVHD (P = .001) and chronic GVHD (P = .002) were significantly lower in Italian pairs. In conclusion, 10/10 HLA matching is a favorable prognostic factor for unrelated HSCT outcome in the Italian population. Moreover, the presence of 2 HLA-mismatched loci was associated with a higher NRM (P < .0001) and grade II-IV aGVHD (P = .006) and a poorer OS (P = .001) compared with 1 HLA-mismatched locus in early or intermediate disease phases. Finally, we found that Italian donor and recipient origin is a favorable prognostic factor for GVHD occurrence.

Isolated cerebellar progressive multifocal leukoencephalopathy after allogeneic bone marrow transplantation: focus on imaging.

Tumori 2021 Dec 25;107(6):NP45-NP48. Epub 2021 Feb 25.

Neuroradiology Unit, Department of Diagnostics, San Bortolo Hospital, Vicenza, Italy.

Introduction: Progressive multifocal leukoencephalopathy (PML) is caused by JC virus opportunistic infection in the setting of immunodeficiency. Typical imaging features are multifocal and asymmetric lesions within supratentorial subcortical white matter in parieto-occipital regions.

Case Description: A 47-year-old patient experienced a relapse of acute myeloid leukemia 21 months after hematopoietic stem cell transplantation. He also had visual impairment and magnetic resonance imaging showed an isolated cerebellar lesion without mass effect or enhancement. Common opportunistic infections and leukemic central nervous system involvement were excluded by cerebrospinal fluid (CSF) analysis. Given the worsening clinical and radiologic scenario, PML was suspected, and CSF protein chain reaction analysis was positive for JC virus.

Conclusions: Given its potential curability, PML should be thoroughly investigated in patients with hematologic neoplasms and atypical isolated cerebellar presentation.

We conducted a retrospective multicenter study including pediatric and adult patients with acute leukemia (AL) who received donor lymphocyte infusions (DLIs) after allogeneic hematopoietic stem cell transplantation (HCT) between January 1, 2010 and December 31, 2015, in order to determine the efficacy and toxicity of the immune treatment. Two hundred fifty-two patients, median age 45.1 years (1.6-73.4), were enrolled from 34 Italian transplant centers. The underlying disease was acute myeloid leukemia in 180 cases (71%). Donors were HLA identical or 1 locus mismatched sibling (40%), unrelated (40%), or haploidentical (20%). The first DLI was administered at a median time of 258 days (55-3,784) after HCT. The main indication for DLI was leukemia relapse (73%), followed by mixed chimerism (17%), and pre-emptive/prophylactic use (10%). Ninety-six patients (38%) received one single infusion, whereas 65 (26%), 42 (17%), and 49 patients (19%) received 2, 3, or ≥4 infusions, respectively, with a median of 31 days between two subsequent DLIs. Forty percent of evaluable patients received no treatment before the first DLI, whereas radiotherapy, conventional chemotherapy or targeted treatments were administered in 3, 39, and 18%, respectively. In informative patients, a few severe adverse events were reported: grade III-IV graft versus host disease (GVHD) (3%), grade III-IV hematological toxicity (11%), and DLI-related mortality (9%). Forty-six patients (18%) received a second HCT after a median of 232 days (32-1,390) from the first DLI. With a median follow-up of 461 days (2-3,255) after the first DLI, 1-, 3-, and 5- year overall survival (OS) of the whole group from start of DLI treatment was 55, 39, and 33%, respectively. In multivariate analysis, older recipient age, and transplants from haploidentical donors significantly reduced OS, whereas DLI for mixed chimerism or as pre-emptive/prophylactic treatment compared to DLI for AL relapse and a schedule including more than one DLI significantly prolonged OS. This GITMO survey confirms that DLI administration in absence of overt hematological relapse and multiple infusions are associated with a favorable outcome in AL patients. DLI from haploidentical donors had a poor outcome and may represent an area of further investigation.

Treatment of steroid resistant acute graft versus host disease with an anti-CD26 monoclonal antibody-Begelomab.

Bone Marrow Transplant 2020 08 13;55(8):1580-1587. Epub 2020 Mar 13.

Dipartimento di Oncoematologia Pediatrica, IRCCS, Ospedale Pediatrico Bambino Gesu', Sapienza, Università di Roma, Roma, Italy.

We have treated 69 patients with steroid refractory acute graft versus host disease (SR-aGvHD), with an anti-CD26 monoclonal antibody (Begelomab): 28 patients in two prospective studies (EudraCT No. 2007-005809-21; EudraCT No. 2012-001353-19), and 41 patients on a compassionate use study. The median age of patients was 42 and 44 years; the severity of GvHD was as follows: grade II in 8 patients, grade III in 33, and grade IV in 28 patients. There were no adverse events directly attributable to the antibody. Day 28 response was 75% in the prospective studies and 61% in the compassionate use patients, with complete response rates of 11 and 12%. Response for grade III GvHD was 83 and 73% in the two groups; response in grade IV GvHD was 66 and 56% in the two groups. Non relapse mortality (NRM) at 6 months was 28 and 38%. Overall there were 64, 56, 68% responses for skin, liver, and gut stage 3-4 GvHD. The overall survival at 1 year was 50% for the prospective studies and 33% for the compassionate use patients. In conclusion, Begelomab induces over 60% responses in SR-aGvHD, including patients with severe gut and liver GvHD, having failed one or more lines of treatment.

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.

A Comparison of the Conditioning Regimens BEAM and FEAM for Autologous Hematopoietic Stem Cell Transplantation in Lymphoma: An Observational Study on 1038 Patients From Fondazione Italiana Linfomi.

Biol Blood Marrow Transplant 2018 09 29;24(9):1814-1822. Epub 2018 May 29.

BEAM (carmustine [bis-chloroethylnitrosourea (BCNU)]-etoposide-cytarabine-melphalan) chemotherapy is the standard conditioning regimen for autologous stem cell transplantation (ASCT) in lymphomas. Owing to BCNU shortages, many centers switched to fotemustine-substituted BEAM (FEAM), lacking proof of equivalence. We conducted a retrospective cohort study in 18 Italian centers to compare the safety and efficacy of BEAM and FEAM regimens for ASCT in lymphomas performed from 2008 to 2015. We enrolled 1038 patients (BEAM = 607, FEAM = 431), of which 27% had Hodgkin lymphoma (HL), 14% indolent non-Hodgkin lymphoma (NHL), and 59% aggressive NHL. Baseline characteristics including age, sex, stage, B-symptoms, extranodal involvement, previous treatments, response before ASCT, and overall conditioning intensity were well balanced between BEAM and FEAM; notable exceptions were median ASCT year (BEAM = 2011 versus FEAM = 2013, P < .001), Sorror score ≥3 (BEAM = 15% versus FEAM = 10%, P = .017), and radiotherapy use (BEAM = 18% versus FEAM = 10%, P < .001). FEAM conditioning resulted in higher rates of gastrointestinal and infectious toxicities, including severe oral mucositis grade ≥3 (BEAM = 31% versus FEAM = 44%, P < .001), and sepsis from Gram-negative bacteria (mean isolates/patient: BEAM = .1 versus FEAM = .19, P < .001). Response status at day 100 post-ASCT (overall response: BEAM = 91% versus FEAM = 88%, P = .42), 2-year overall survival (83.9%; 95% confidence interval [CI], 81.5% to 86.1%) and progression-free survival (70.3%; 95% CI, 67.4% to 73.1%) were not different in the two groups. Mortality from infection was higher in the FEAM group (subhazard ratio, 1.99; 95% CI, 1.02 to 3.88; P = .04). BEAM and FEAM do not appear different in terms of survival and disease control. However, due to concerns of higher toxicity, fotemustine substitution in BEAM does not seem justified, if not for easier supply.

Evaluation of lymphocytes inactivation by extracorporeal photopheresis using tetrazolium salt based-assay.

Transfus Apher Sci 2015 Oct 27;53(2):242-5. Epub 2015 May 27.

Department of Cellular Therapy and Hematology, San Bortolo Hospital, Vicenza, Italy. Electronic address:

Extracorporeal photopheresis (ECP) is accepted as a second-line therapy for the treatment of acute and chronic steroid-refractory graft versus host disease (GvHD), cutaneous T-cell lymphoma and solid organ transplantation. ECP should be validated: we compared in parallel apoptosis and proliferation analysis of patient lymphocytes treated with 8-MOP ECP using respectively Annexin V/7-aminoactinomycin D (7-AAD) and CFSE with a tetrazolium salt (WST-1) method. Using WST-1 assay we found a significant decrement (p < 0.01) of metabolic activity at 4 days between ECP-treated and untreated cells. This finding was confirmed by the significant decrease of cell proliferation and increase of cell death observed by CFSE and 7AAD-Annexin V, respectively. Accordingly, once validated against a reference method, WST-1 could represent a rapid and easy assay for routinely quality control of ECP.

Chemotherapy-phased imatinib pulses improve long-term outcome of adult patients with Philadelphia chromosome-positive acute lymphoblastic leukemia: Northern Italy Leukemia Group protocol 09/00.

J Clin Oncol 2010 Aug 6;28(22):3644-52. Epub 2010 Jul 6.

U.S.C. Ematologia, Ospedali Riuniti, Bergamo, Italy.

Purpose: Short imatinib pulses were added to chemotherapy to improve the long-term survival of adult patients with Philadelphia chromosome (Ph) -positive acute lymphoblastic leukemia (ALL), to optimize complete remission (CR) and stem-cell transplantation (SCT) rates.

Patients And Methods: Of 94 total patients (age range, 19 to 66 years), 35 represented the control cohort (ie, imatinib-negative [IM-negative] group), and 59 received imatinib 600 mg/d orally for 7 consecutive days (ie, imatinib-positive [IM-positive] group), starting from day 15 of chemotherapy course 1 and from 3 days before chemotherapy during courses 2 to 8. Patients in CR were eligible for allogeneic SCT or, alternatively, for high-dose therapy with autologous SCT followed by long-term maintenance with intermittent imatinib.

Results: CR and SCT rates were greater in the IM-positive group (CR: 92% v 80.5%; P = .08; allogeneic SCT: 63% v 39%; P = .041). At a median observation time of 5 years (range, 0.6 to 9.2 years), 22 patients in the IM-positive group versus five patients in the IM-negative group were alive in first CR (P = .037). Patients in the IM-positive group had significantly greater overall and disease-free survival probabilities (overall: 0.38 v 0.23; P = .009; disease free: 0.39 v 0.25; P = .044) and a lower incidence of relapse (P = .005). SCT-related mortality was 28% (ie, 15 of 54 patients), and postgraft survival probability was 0.46 overall.

Conclusion: This imatinib-based protocol improved long-term outcome of adult patients with Ph-positive ALL. With SCT, post-transplantation mortality and relapse remain the major hindrance to additional therapeutic improvement. Additional intensification of imatinib therapy should warrant a better molecular response and clinical outcome, both in patients selected for SCT and in those unable to undergo this procedure.

Flow cytometry in the diagnosis of drug-induced thrombocytopenia: two illustrative cases.

Am J Hematol 2008 Apr;83(4):326-9

Department of Hematology, San Bortolo Hospital, Vicenza, Italy.

Drug-induced thrombocytopenia is a challenging diagnosis in the clinical practice because of the many drugs or alternative causes that may be implicated. Exact identification of such drug(s) is required to guide future management and avoid re-exposure. We describe two cases of isolated thrombocytopenia in which cytometric analysis, a readily available technique, allowed the identification of the causative drug in the context of complex therapies (rifampicin and abciximab causing late onset thrombocytopenia).

Association between Enterococcus bacteraemia and death in neutropenic patients with haematological malignancies.

J Infect 2006 Oct 4;53(4):266-73. Epub 2006 Jan 4.

Department of Haematology, University of Verona, Verona, Italy.

Fatality rates and prognostic factors for mortality due to Enterococcus spp. bacteraemia have not yet been fully defined in the setting of neutropenic patients affected with haematological malignancies. We have performed a retrospective, multi-centre cohort study on 98 episodes of Enterococcus bacteraemia occurring in patients hospitalised from January 1984 to December 2001 at the oncohaematology units in two tertiary-care hospitals (Verona Hospital and Vicenza Hospital, in north-east Italy). E. faecalis was isolated in 52 cases (53%), E. faecium in 39 (39.8%), E. avium in four, E. durans in one, and untyped Enterococcus spp. in two other cases; vancomycin resistance was detected in 15 (15.3%) isolates. A global mortality rate of 41.8% (41/98 cases) was revealed; Enterococcus spp. bacteraemia was associated with a fatal outcome in 29/98 cases (29.5%). The following variables were independently associated with an increased risk of death by multivariate analysis of survival: age > or =50 years (OR 3.74; 95% CI 1.35-10.32), pneumonia (OR 4.70; 95% CI 1.67-13.20), and shock (OR 13.7; 95% CI 1.23-152.43), while the initial phase of haematological disease (responsive to chemotherapy) appeared to be protective (OR 0.23; 95% CI 0.008-0.64, P level 0.005); however, pneumonia alone (OR 7.2, 95% CI 2.52-20.88) was independently associated with fatal outcome by multivariate analysis for death related to enterococcal bacteraemia. In our experience, the poor outcome proper to enterococcal bacteraemia appears to be directly related to underlying disease, patient's age, presence of pneumonia and shock; in contrast, severe neutropaenia, antibiotic resistance, and species of Enterococcus do not appear to affect the fatality rate significantly.
