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.

The detection of circulating plasma cells may improve the Revised International Staging System (R-ISS) risk stratification of patients with newly diagnosed multiple myeloma.

Br J Haematol 2021 05 1;193(3):542-550. Epub 2021 Apr 1.

Department of Haematology and Stem Cell Transplantation Unit, C. e G. Mazzoni Hospital, Ascoli Piceno, Italy.

The Revised International Staging System (R-ISS) stratifies patients affected by Multiple Myeloma (MM) into three distinct risk groups: R-ISS I [ISS Stage I, Standard-Risk cytogenetics and normal Lactase DeHydrogenase (LDH)], R-ISS III (ISS stage III and either high-risk cytogenetics or high LDH) and R-ISS II (any other characteristics). With the aim to verify whether the three R-ISS groups could be divided into subgroups with different prognostic factors based on the detection of Circulating Plasma Cells (CPCs) at diagnosis, in this retrospective analysis, we evaluated 161 patients with MM treated at our centre between 2005 and 2017. In all, 57 patients (33·9%) were staged as R-ISS III, 98 (58·3%) as R-ISS II and six (3·6%) as R-ISS I. CPCs were detected in 125 patients (74·4%), while in 43 patients (25·6%) no CPCs were seen. Our analysis revealed that Overall Survival (OS) and progression-free survival (PFS) rates in R-ISS II patients were higher in the subgroup without CPCs compared to the subgroup with ≥1 CPCs (OS: 44·7% vs. 16·3%, P = 0·0089; PFS: 27·8% vs. 8·1%, P = 0·0118). Our present findings suggest that the detection of CPCs at diagnosis may be used as a further prognostic biomarker to improve the risk stratification of patients with MM staged as R-ISS II.

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.

Detection of circulating plasma cells (PCs) in multiple myeloma (MM) patients is a well-known prognostic factor. We evaluated circulating PCs by flow cytometry (FC) in 104 patients with active MM at diagnosis by gating on CD38(+)  CD45(-) cells and examined their relationship with cytogenetic risk. Patients had an average follow-up of 36 months. By using a receiver operating characteristics analysis, we estimated the optimal cut-off of circulating PCs for defining poor prognosis to be 41. Patients with high-risk cytogenetics (n = 24) had poor prognosis, independently of circulating PC levels [PC < 41 vs. PC ≥ 41: overall survival (OS) = 0% vs. OS = 17%, P = not significant (n.s.); progression-free survival (PFS) = 0% vs. 17%, P = n.s.]. Patients with standard-risk cytogenetics (n = 65) showed a better prognosis when associated with a lower number of circulating PCs (PC < 41 vs. PC ≥ 41: OS = 62% vs. 24%, P = 0·008; PFS = 48% vs. 21%, P = 0·001). Multivariate analysis on the subgroup with standard-risk cytogenetics confirmed that the co-presence of circulating PCs ≥ 41, older age, Durie-Salmon stage >I and lack of maintenance adversely affected PFS, while OS was adversely affected only by lactate dehydrogenase, older age and lack of maintenance. Our results indicate that the quantification of circulating PCs by a simple two-colour FC analysis can provide useful prognostic information in newly diagnosed MM patients with standard-risk cytogenetics.

Incidence and outcome of invasive fungal diseases after allogeneic stem cell transplantation: a prospective study of the Gruppo Italiano Trapianto Midollo Osseo (GITMO).

Biol Blood Marrow Transplant 2014 Jun 14;20(6):872-80. Epub 2014 Mar 14.

First Medical Division of Onco-hematology, Ospedale Civile di Piacenza, Piacenza, Italy.

Epidemiologic investigation of invasive fungal diseases (IFDs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be useful to identify subpopulations who might benefit from targeted treatment strategies. The Gruppo Italiano Trapianto Midollo Osseo (GITMO) prospectively registered data on 1858 consecutive patients undergoing allo-HSCT between 2008 and 2010. Logistic regression analysis was performed to identify risk factors for proven/probable IFD (PP-IFD) during the early (days 0 to 40), late (days 41 to 100), and very late (days 101 to 365) phases after allo-HSCT and to evaluate the impact of PP-IFDs on 1-year overall survival. The cumulative incidence of PP-IFDs was 5.1% at 40 days, 6.7% at 100 days, and 8.8% at 12 months post-transplantation. Multivariate analysis identified the following variables as associated with PP-IFDs: transplant from an unrelated volunteer donor or cord blood, active acute leukemia at the time of transplantation, and an IFD before transplantation in the early phase; transplant from an unrelated volunteer donor or cord blood and grade II-IV acute graft-versus-host disease (GVHD) in the late phase; and grade II-IV acute GVHD and extensive chronic GVHD in the very late phase. The risk for PP-IFD was significantly higher when acute GVHD was followed by chronic GVHD and when acute GVHD occurred in patients undergoing transplantation with grafts from other than matched related donors. The presence of PP-IFD was an independent factor in long-term survival (hazard ratio, 2.90; 95% confidence interval, 2.32 to 3.62; P < .0001). Our findings indicate that tailored prevention strategies may be useful in subpopulations at differing levels of risk for PP-IFDs.

6q deletion detected by fluorescence in situ hybridization using bacterial artificial chromosome in chronic lymphocytic leukemia.

Eur J Haematol 2013 Jul 24;91(1):10-9. Epub 2013 May 24.

SC Ematologia Ospedale C. G. Mazzoni, Ascoli Piceno, Italy.

Deletions of the long arm of chromosome 6 are known to occur at relatively low frequency (3-6%) in chronic lymphocytic leukemia (CLL), and they are more frequently observed in 6q21. Few data have been reported regarding other bands on 6q involved by cytogenetic alterations in CLL. The cytogenetic study was performed in nuclei and metaphases obtained after stimulation with a combination of CpG-oligonucleotide DSP30 and interleukin-2. Four bacterial artificial chromosome (BAC) clones mapping regions in bands 6q16, 6q23, 6q25, 6q27 were used as probes for fluorescence in situ hybridization in 107 CLL cases in order to analyze the occurrence and localization of 6q aberrations. We identified 11 cases (10.2%) with 6q deletion of 107 patients studied with CLL. The trends of survival curves and the treatment-free intervals (TFI) of patients with deletion suggest a better outcome than the other cytogenetic risk groups. We observed two subgroups with 6q deletion as the sole anomaly: two cases with 6q16 deletion, and three cases with 6q25.2-27 deletion. There were differences of age, stage, and TFI between both subgroups. By using BAC probes, we observed that 6q deletion has a higher frequency in CLL and is linked with a good prognosis. In addition, it was observed that the deletion in 6q16 appears to be the most frequent and, if present as the only abnormality, it could be associated with a most widespread disease.

BeEAM (bendamustine, etoposide, cytarabine, melphalan) before autologous stem cell transplantation is safe and effective for resistant/relapsed lymphoma patients.

Blood 2011 Sep 3;118(12):3419-25. Epub 2011 Aug 3.

Hematology and Stem Cell Transplant Center, Marche Nord Hospital, Pesaro, Italy.

We designed a phase 1-2 study to evaluate the safety and the efficacy of increasing doses of bendamustine (160 mg/m², 180 mg/m², and 200 mg/m² given on days -7 and -6) coupled with fixed doses of etoposide, cytarabine, and melphalan (BeEAM regimen) as the conditioning regimen to autologous stem cell transplantation for resistant/relapsed lymphoma patients. Forty-three patients (median age, 47 years) with non-Hodgkin (n = 28) or Hodgkin (n = 15) lymphoma were consecutively treated. Nine patients entered the phase 1 study; no patients experienced a dose-limiting toxicity. Thirty-four additional patients were then treated in the phase 2. A median number of 6 × 10⁶ CD34(+) cells/kg (range, 2.4-15.5) were reinfused. All patients engrafted, with a median time to absolute neutrophil count > 0.5 × 10⁹/L of 10 days. The 100-day transplantation-related mortality was 0%. After a median follow-up of 18 months, 35 of 43 patients (81%) are in complete remission, whereas 6 of 43 relapsed and 2 of 43 did not respond. Disease type (non-Hodgkin lymphomas vs Hodgkin disease) and disease status at transplantation (chemosensitive vs chemoresistant) significantly influenced DFS (P = .01; P = .007). Remarkably, 4 of 43 (9%) patients achieved the first complete remission after receiving the high-dose therapy with autologous stem cell transplantation. In conclusion, the new BeEAM regimen is safe and effective for heavily pretreated lymphoma patients. The study was registered at European Medicines Agency (EudraCT number 2008-002736-15).

ThaDD plus high dose therapy and autologous stem cell transplantation does not appear superior to ThaDD plus maintenance in elderly patients with de novo multiple myeloma.

Eur J Haematol 2010 Jun 11;84(6):474-83. Epub 2010 Mar 11.

Clinica di Ematologia Azienda Ospedaliero-Universitaria, Ospedali Riuniti di Ancona, Ancona.

Objectives: With the aim to address the issue whether high-dose therapy (HDT) is required after new drugs combinations to improve outcome of elderly newly diagnosed multiple myeloma (MM) patients, we compared the toxicity and the outcome of ThaDD plus maintenance to those of ThaDD plus HDT-autologous stem cell transplantation (ASCT).

Methods: Sixty-two patients not eligible for HDT receiving six courses of ThaDD regimen plus maintenance with thalidomide were compared to 26 patients eligible for HDT treated with four courses of ThaDD followed by melphalan 100-200 mg/m(2) and ASCT. The two groups were matched for the main characteristics except for age favouring the HDT group.

Results And Conclusions: Complete remission (CR) obtained with ThaDD plus maintenance was 24% whereas it was 57% after ThaDD plus HDT-ASCT (P = 0.0232). However, after a median follow-up of 36 months, median time to progression (TTP) and progression free survival (PFS) of the group of patients undergone HDT were not significantly different to those of patients receiving ThaDD plus maintenance (32 vs. 31 months: P = 0.962; 32 vs. 29 months: P = 0.726, respectively). Five-year overall survival (OS) was 49% in the first group and 46% in the latter one (P = 0.404). As expected, a significantly higher incidence of grade 3-4 neutropenia, thrombocytopenia, infections, mucositis and alopecia were observed in the ThaDD plus HDT group. Our results suggest that in elderly MM patients ThaDD plus HDT, albeit significantly increases CR rate, seems to be equivalent to ThaDD plus maintenance in terms of TTP, PFS and OS. These results challenge the requirement for HDT consolidation in this subset of patients.

Acute graft-versus-host disease and steroid treatment impair CD11c+ and CD123+ dendritic cell reconstitution after allogeneic peripheral blood stem cell transplantation.

Biol Blood Marrow Transplant 2004 Feb;10(2):106-15

Research Center for Transplant Immunology, Institute of Hematology and Medical Oncology Seràgnoli, University of Bologna, Italy.

Human dendritic cells (DC) comprise 2 subsets-plasmacytoid CD123(+) and myeloid CD11c(+) DC-that may have distinct roles in the regulation of immunity after allogeneic hematopoietic stem cell transplantation. In this study, we analyzed the kinetics of CD123(+) DC and CD11c(+) DC reconstitution in 31 patients who underwent transplantation with allogeneic granulocyte colony-stimulating factor-mobilized peripheral blood (PB) stem cells from HLA-identical sibling donors after myeloablative conditioning. Lineage marker-negative HLA-DR(+) CD11c(+) CD11c(+) DC and lineage marker-negative HLA-DR(+) CD123(+) CD123(+) DC, as well as monocytes and lymphoid subsets, were enumerated in donor grafts and in the PB of patients at various time points after transplantation. Reconstitution of both CD11c(+) DC and CD123(+) DC to normal levels occurred within 6 to 12 months and was not affected by the diagnosis, preparatory regimen, or graft composition. However, PB CD11c(+) DC and CD123(+) DC counts were significantly reduced in patients with acute GVHD grade II to IV (at 1 and 3 months) and grade I (at 1 month). Patients with chronic GVHD instead showed reduced CD123(+) DC counts only 6 months after transplantation. Moreover, treatment with steroids (>0.1 mg/kg) was significantly associated with reduced PB CD11c(+) DC and CD123(+) DC counts at all time points after transplantation. In multivariate analysis, only acute GVHD affected DC reconstitution early after transplantation. These results will prompt new studies addressing whether DC reconstitution correlates with immunity against infectious agents or with graft-versus-tumor reactions after PB stem cell allotransplantation.

Allogeneic graft CD34(+) cell dose correlates with dendritic cell dose and clinical outcome, but not with dendritic cell reconstitution after transplant.

Exp Hematol 2003 Oct;31(10):959-65

Research Center for Transplant Immunology, Institute of Hematology and Medical Oncology "Seràgnoli," University of Bologna, Bologna, Italy.

Objective: This study examined whether the CD34(+) cell dose in allografts correlates with the dose of myeloid dendritic cells (mDC) and plasmacytoid DC (pDC), and with DC reconstitution and clinical outcome after a myeloablative HLA-matched transplant.

Patients And Methods: Fifty-three patients were included in this study: 37 who had undergone a granulocyte colony-stimulating factor mobilized peripheral blood stem cells (PBSC) transplant from related donors and 16 who had undergone a marrow transplant from unrelated donors. The number of CD34(+) cells, lin(-)HLA-DR(+)CD11c(+) mDC, lin(-)HLA-DR(+)CD123(+) pDC, CD14(+) monocytes, and CD3(+)CD4(+), CD3(+)CD8(+), CD56(+), and CD19(+) lymphocytes was compared in the graft, as well as in the peripheral blood after transplant, in patients receiving more than versus less than or equal to the median number of CD34(+) cells in PBSC (5.78 x 10(6)/kg) or in marrow (2.8 x 10(6)/kg).

Results: A higher CD34(+) cell dose was associated with larger numbers of mDC in PBSC (p=0.01) and pDC in marrow grafts (p=0.004). However, neither mDC nor pDC recovery after transplant correlated with the number of CD34(+) cells infused. Finally, higher doses of CD34(+) cells appeared to negatively affect (p=0.02) the overall survival in PBSC transplantation and were associated with a trend for higher acute graft-vs-host disease in PBSC and lower acute graft-vs-host disease in marrow transplant.

Conclusions: CD34(+) cell dose correlates with the dose of different DC subsets in PBSC and marrow grafts, but it does not affect DC reconstitution after transplant. Higher doses of CD34(+) cells in PBSC, but not in marrow, seem to adversely affect survival after transplant.
