Donor selection may contribute to improve clinical outcomes of T cell-replete haploidentical stem cell transplantation (Haplo-SCT) with post-transplant cyclophosphamide (PT-Cy). Impact of second-degree related donor (SRD) was not fully elucidated in this platform. We retrospectively compared the outcome of patients receiving Haplo-SCT either from a SRD (n = 31) or a first-degree related donor (FRD, n = 957). Median time to neutrophil and platelet recovery did not differ between a SRD and a FRD transplant (p = 0.599 and 0.587). Cumulative incidence of grade II-IV acute graft-versus host disease (GVHD) and moderate-severe chronic GVHD was 13% and 19% after SRD vs 24% (p = 0.126) and 13% (p = 0.395) after FRD transplant. One-year cumulative incidence of non-relapse mortality (NRM) was 19% for SRD and 20% for FRD (p = 0.435) cohort. The 3-year probability of overall survival (OS) and progression-free survival (PFS) was 42% vs 55% (p = 0.273) and 49% vs 35% (p = 0.280) after SRD and FRD transplant, respectively. After propensity score adjustment or matched pair analysis, the outcome of patients receiving Haplo-SCT from a SRD or a FRD did not differ in terms of NRM, OS, PFS, acute and chronic GVHD. Our results suggest that a SRD is a viable option for Haplo-SCT with PT-Cy when a FRD is not available.

Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequent adverse events compromising quality of life (QoL) in patients undergoing autologous stem cell transplantation (ASCT). However, CINV prophylaxis is still lacking uniformity for high-dose melphalan (HDM), which is used to condition patients with multiple myeloma (MM). Netupitant/palonosetron (NEPA) is administered with dexamethasone (DEXA) for CINV prevention in several chemotherapy regimens. Our study aims to assess the efficacy of NEPA, without DEXA, in preventing CINV in 106 adult patients with MM receiving HDM and ASCT. All patients had antiemetic prophylaxis with multiple doses of NEPA 1 h before the start of conditioning and after 72 h and 120 h. A complete response (CR) was observed in 99 (93%) patients at 120 h (overall phase). The percentage of patients with complete control was 93%. The CR rate during the acute phase was 94% (n = 100). During the delayed phase, the CR rate was 95% (n = 101). Grade 1 nausea and vomiting were experienced by 82% and 12% of the patients, respectively. Grade 2 nausea was reported in 18% and vomiting in 10% of patients. Our results showed, for the first time, that NEPA, without DEXA, was a well-tolerated and effective antiemetic option for MM patients receiving HDM followed by ASCT.

G-CSF administration after high-dose chemotherapy and autologous stem cell transplantation (ASCT) has been shown to expedite neutrophil recovery. Several studies comparing filgrastim and pegfilgrastim in the post-ASCT setting concluded that the two are at least equally effective. Lipegfilgrastim (LIP) is a new long-acting, once-per-cycle G-CSF. This multicentric, prospective study aimed to describe the use of LIP in multiple myeloma patients receiving high-dose melphalan and autologous stem cell transplantation (ASCT) and compare LIP with historic controls of patients who received short-acting agent (filgrastim [FIL]). Overall, 125 patients with a median age of 60 years received G-CSF after ASCT (80 patients LIP on day 1 post-ASCT and 45 patients FIL on day 5 post-ASCT). The median duration of grade 4 neutropenia (absolute neutrophil count [ANC]

INTRODUCTION Chimeric antigen receptor (CAR)-T-cell therapy is a new treatment for patients with hematologic malignancies in which other therapies have failed. AREAS COVERED The review provides an overview for recognizing and managing the most acute toxicities related to CAR-T cells. EXPERT OPINION The development of immune-mediated toxicities is a common challenge of CAR-T therapy. The mechanism that determines this toxicity is still unclear, although an unfavorable tumor microenvironment and a pro-inflammatory state put patients at risk. The monitoring, diagnosis, and treatment of post-CAR-T toxicities must be determined and based on international guidelines and internal clinical practice. It is urgent to identify biomarkers that can identify patients at greater risk of developing complications. The adoption of consistent grading criteria is necessary to improve toxicity management strategies continually. The first-line therapy consists of supportive care and treatment with tocilizumab or corticosteroids. An early start of cytokine blockade therapies could mitigate toxicity. The plan will include cytokine release prophylaxis, a risk-adapted treatment, prevention of on-target/off-tumor effect, and a switch on/off CAR-T approach.

A longitudinal, prospective, observational, single-center cohort study on healthy donors was designed to identify predictors of CD34+ cell mobilization on day 4 after granulocyte colony-stimulating factor (G-CSF) administration. As potential predictors of mobilization, age, sex, body weight, height, blood volume, WBC count, peripheral blood (PB) mononuclear cell count, platelet (Plt) count, and hematocrit and hemoglobin levels were considered. Two different evaluations of CD34+ cell counts were determined for each donor: baseline (before G-CSF administration) and in PB on day 4 after G-CSF administration. One hundred twenty-two consecutive healthy donors with a median age of 47.5 years were enrolled. The median value of CD34+ on day 4 was 43 cells/µL (interquartile range, 23 to 68), and 81.1% of donors had ≥20 cells/µL. Basal WBC count, Plt count, and CD34+ were significantly higher for the subjects with CD34+ levels over median values on day 4. A multivariate quartile regression analysis, adjusted by sex, age, basal CD34+, and basal Plt count, showed a progressively stronger relationship between baseline CD34+ and Plt levels and the CD34+ levels on day 4. The basal CD34+ cut-off level to predict the levels of CD34+ on day 4 was either ≤2 cells/μL or ≥3 cells/μL and that of basal Plt count was ≤229 × 109/L or ≥230 × 109/L, respectively, to determine whether mobilization therapy should or should not be attempted. PB stem cell mobilization with G-CSF was highly effective on day 4, and herein we describe a model for predicting the probability of performing PB stem cell collection after a short course of G-CSF.

Background: FDA designated ibrutinib as a breakthrough therapy in Mantle Cell Lymphoma (MCL) and Chronic Lymphocytic Leukemia (CLL). Nevertheless, patients who progress under ibrutinib still have a poor prognosis. In this setting, allogeneic hematopoietic stem cell transplantation (allo-HSCT) could induce long-term disease control.Areas covered: The purpose of the present review is to provide information on the efficacy of ibrutinib when administered before and after allo-HSCT for CLL and MCL. Moreover, we will focus on the current role of ibrutinib for chronic GVHD.Expert opinion: Ibrutinib as bridge to allo-HSCT does not appear to affect the safety of the treatment in patients with CLL and MCL. Current evidence support further evaluation of ibrutinib for the treatment of relapsed CLL and MCL after allo-HSCT. In this setting, ibrutinib should be not only highly efficient on CLL and MCL cells but might also have the ability to enhance the activity of donor T cells. Chronic GVHD is the most common ...

Donor selection contributes to improve clinical outcomes of T-cell–replete haploidentical stem cell transplantation (haplo-SCT) with posttransplant cyclophosphamide (PT-Cy). The impact of donor age and other non-HLA donor characteristics remains a matter of debate. We performed a multicenter retrospective analysis on 990 haplo-SCTs with PT-Cy. By multivariable analysis, after adjusting for donor/recipient kinship, increasing donor age and peripheral blood stem cell graft were associated with a higher risk of grade 2 to 4 acute graft-versus-host-disease (aGVHD), whereas 2-year cumulative incidence of moderate-to-severe chronic GVHD was higher for transplants from female donors into male recipients and after myeloablative conditioning. Increasing donor age was associated with a trend for higher nonrelapse mortality (NRM) (hazard ratio [HR], 1.05; P = .057) but with a significant reduced risk of disease relapse (HR, 0.92; P = .001) and improved progression-free survival (PFS) (HR, 0.97; P = .036). Increasing recipient age was a predictor of worse overall survival (OS). Risk of relapse was higher (HR, 1.39; P < .001) in patients aged ≤40 years receiving a transplant from a parent as compared with a sibling. Moreover, OS and PFS were lower when the donor was the mother rather than the father. Pretransplant active disease status was an invariably independent predictor of worse clinical outcomes, while recipient positive cytomegalovirus serostatus and hematopoietic cell transplant comorbidity index >3 were associated with worse OS and PFS. Our results suggest that younger donors may reduce the incidence of aGVHD and NRM, though at higher risk of relapse. A parent donor, particularly the mother, is not recommended in recipients ≤40 years.

Simple Summary Available data on anti-BCMA CART-cell therapy has demonstrated efficacy and manageable toxicity in heavily pretreated R/R MM patients. Despite this, the main issues remain to be addressed. First of all, a significant proportion of patients eventually relapse. The potential strategy to prevent relapse includes sequential or combined infusion with CAR T-cells against targets other than BCMA, CAR T-cells with novel dual-targeting vector design, and BCMA expression upregulation. Another dark side of CAR T therapy is safety. Cytokine release syndrome (CRS) and neurologic toxicity are well-described adverse effects. In MM trials, most CRS events tended to be grade 1 or 2. Another critical point is the extended timeline of the manufacturing process and that only a few academic centers can perform these procedures. Recognizing these issues, the excellent response with BCMA-targeted CAR T-cell therapy makes it a treatment strategy of great promise. Abstract Despite the improvement in survival outcomes, multiple myeloma (MM) remains an incurable disease. Chimeric antigen receptor (CAR) T-cell therapy targeting B-cell maturation antigen (BCMA) represents a new strategy for the treatment of relapsed/refractory MM (R/R). In this paper, we describe several recent advances in the field of anti-BCMA CAR T-cell therapy and MM. Currently, available data on anti-BCMA CART-cell therapy has demonstrated efficacy and manageable toxicity in heavily pretreated R/R MM patients. Despite this, the main issues remain to be addressed. First of all, a significant proportion of patients eventually relapse. The potential strategy to prevent relapse includes sequential or combined infusion with CAR T-cells against targets other than BCMA, CAR T-cells with novel dual-targeting vector design, and BCMA expression upregulation. Another dark side of CART therapy is safety. Cytokine release syndrome (CRS) andneurologic toxicity are well-described adverse effects. In the MM trials, most CRS events tended to be grade 1 or 2, with fewer patients experiencing grade 3 or higher. Another critical point is the extended timeline of the manufacturing process. Allo-CARs offers the potential for scalable manufacturing for on-demand treatment with shorter waiting days. Another issue is undoubtedly going to be access to this therapy. Currently, only a few academic centers can perform these procedures. Recognizing these issues, the excellent response with BCMA-targeted CAR T-cell therapy makes it a treatment strategy of great promise.

PURPOSE Cyclophosphamide (CY) in a dose of 2–4 g/m2 is widely used for hemopoietic progenitor stem cells mobilization. CY administration is associated with several adverse effects, including chemotherapy-induced nausea and vomiting (CINV). This study aimed to evaluate the efficacy and tolerability of granisetron transdermal system (GTDS) plus dexamethasone in the management of CINV in MM patients undergoing chemo-mobilization with CY. METHODS In this single-center, prospective, observational, real world study, GTDS plus dexamethasone was administered to MM patients receiving chemo-mobilization based on CY 2 g/m2 plus G-CSF in an outpatient setting. The rate of complete response was evaluated as the main outcome. Other outcomes were rate of complete control of CINV, incidence of nausea/vomiting of any grade and safety. RESULTS A total of 88 patients were enrolled. A complete response was achieved in 45.5 % of patients; among them, 39.77 % attained complete control of CINV. Nausea and vomiting never occurred in 34.1 % and 45.5 % of patients, respectively. No episodes of grade 3–4 nausea and/or vomiting were documented. GTDS was safe and well tolerated. CONCLUSION In real world, GTDS provided an innovative, effective, and well-tolerated control of CINV in MM patients after chemo-mobilization with CY. The study found out effectiveness of a non-invasive delivery system of antiemetic.

Mantle cell lymphoma (MCL) accounts for about 5% of all lymphomas. Its clinical and histological features are heterogeneous. After a frequently good initial response, the disease generally and repeatedly relapses and finally the outcome is poor. Particularly severe is the prognosis of the rare occurrence of CNSi (Central Nervous System involvement). Ibrutinib, an oral inhibitor of Bruton tyrosine kinase (BTK), has shown strong activity in relapsing patients with Chronic Lymphocytic Leukemia (CLL) and MCL. Few reports are available about treatment with ibrutinib of patients presenting CNSi by lymphoproliferative diseases (LPD). In all of them, ibrutinib, at the dosage between 420 and 560 mg/day, showed an impressive effectiveness. Here we describe a case of MCL with CNS relapse showing an excellent response to ibrutinib administered at the unusual dose of 280 mg/day because of concomitant treatment of cardiological disease.

Angiogenesis is critical for the clinical progression of haematopoietic malignancies and depends on angiogenic factors. Angiogenin is a powerful factor produced by neoplastic cells and host microenvironment. High levels of soluble angiogenin (sAng) correlate with a poor prognosis in patients affected by acute myeloid leukaemia and myelodysplastic syndromes, but no data are available on sAng in chronic myeloproliferative disorders (CMD). Therefore, in this study we investigated the clinical significance of the angiogenin in sera of patients with chronic myeloid leukaemia (CML) (n = 14) or essential thrombocythaemia (ET) (n = 20), and correlated them with those of soluble transforming growth factor-beta(1) (sTGF beta(1)). Enzyme-linked immunosorbent assay detected (P < 0.05) higher levels of sAng in CMD compared with healthy subjects (1026.74 +/- 464.60 pg/mL and 196.00 +/- 39.90 pg/mL, respectively). The highest levels of sAng were detected in CML patients (1349.23 +/- 549.55 pg/mL). Interestingly, CML patients who achieved haematological remission after interferon therapy showed circulating levels of angiogenin significantly (P < 0.05) decreased when compared with those at diagnosis. In ET patients, levels of angiogenin (889.34 +/- 267.66 pg/mL) and sTGF beta(1) (76.69 +/-6.08 pg/mL) were higher (P < 0.05) compared with healthy controls (57.93 +/- 19.39 pg/mL). No correlation was found between levels of sAng and levels of sTGF beta(1) or platelet count among ET patients. Our results show for the first time that elevated blood levels of angiogenin feature chronic myeloid malignancies, suggesting a role of angiogenin in the pathogenesis of these diseases.

Abnormal blood lipid profiles have been reported in human malignancies. So, it is likely an overall involvement of tumoral cell metabolism. The aim of this study was to evaluate clinico-biological implications of altered lipid profiles in oncohaematologic patients.The plasma lipids, lipoproteins and apolipoproteins were determined at the time of diagnosis in 48 previously untreated patients (35M, 13F, median age 60 years), 11 with multiple myeloma (MM), 11 with non-Hodgkin's lymphoma (NHL), 11 with acute leukemia (AL), 10 with chronic myeloproliferative disorders (CMD) and 5 with B-chronic lymphocytic leukemia (B-CLL). The results were correlated with known prognostic serum markers, such as lactate dehydrogenase (LDH), beta-2-microglobulin (beta 2m), and soluble molecule ICAM1 (sICAM1).Altered blood lipid profiles were observed in all concohaematologic patients. Statistically significant values included reduced cholesterol (155 +/- 47.36 vs 205 +/- 35 mg/dl; p0.001), HDL-C (30.47 +/- 13.36 vs 45 +/- 10 mg/dl; p0.003) and apo A (118.86 +/- 49.98 vs 182.69 mg/dl; p0.0001) levels. No correlations were found between cholesterol levels and clinico-biological features representative of tumor mass (LDH, beta 2m, sICAM-1). A significant increase of cholesterol levels was observed in all patients responding to therapy.These results support the idea that the cholesterol, its fractions and the apolipoproteins determinations might be considered as useful biochemical and prognostic markers in hematologic neoplasms.
