ABSTRACT
BACKGROUND: This study aimed to determine whether implementing a rapid response system (RRS) is associated with improved short-term outcomes in critically ill patients with haematological malignancies. METHODS: Our monocentric pre- versus post-intervention study was conducted between January 2012 and April 2020. RRS was activated at early signs of haemodynamic or respiratory failure. The primary outcome was the reduction in Sequential Organ Failure Assessment (SOFA) score on Day 3 after intensive care unit (ICU) admission. Secondary outcomes included time to ICU admission and mortality. RESULTS: A total of 209 patients with a median age of 59 years were enrolled (108 in the pre-intervention period and 101 in the post-intervention period). 22% of them had received an allogeneic transplant. The post-intervention period was associated with a shorter time to ICU admission (195 vs. 390 min, p < .001), a more frequent favourable trend in SOFA score (57% vs. 42%, adjusted odds ratio, 2.02, 95% confidence interval, 1.09 to 3.76), no significant changes in ICU (22% vs. 26%, p = .48) and 1-year (62% vs. 58%, p = .62) mortality rates. CONCLUSION: Detection of early organ failure and activation of an RRS was associated with faster ICU admission and lower SOFA scores on Day 3 of admission in critically ill patients with haematological malignancies.

PURPOSE: Helical Tomotherapy (HT) appears as a valuable technique for total body irradiation (TBI) to create highly homogeneous and conformal dose distributions with more precise repositioning than conventional TBI techniques. The aim of this work is to describe the technique implementation, including treatment preparation, planning and dosimetric monitoring of TBI delivered in our institution from October 2016 to March 2019. MATERIAL AND METHOD: Prior to patient care, irradiation protocol was set up using physical phantoms. Gafchromic films were used to assess dose distribution homogeneity and evaluate imprecise patient positioning impact. Sixteen patients' irradiations with a prescribed dose of 12Gy were delivered in 6 fractions of 2Gy over 3 days. Pre-treatment quality assurance (QA) was performed for the verification of dose distributions at selected positions. In addition, in-vivo dosimetry was carried out using optically stimulated luminescence dosimeters (OSLD). RESULTS: Planning evaluation, as well as results of pre-treatment verifications, are presented. In-vivo dosimetry showed the strong consistency of OSLD measured doses. OSLD mean relative dose differences between measurement and calculation were respectively +0,96% and -2% for armpit and hands locations, suggesting better reliability for armpit OSLD positioning. Repercussion of both longitudinal and transversal positioning inaccuracies on phantoms is depicted up to 2cm shifts. CONCLUSION: The full methodology to set up TBI protocol, as well as dosimetric evaluation and pre-treatment QA, were presented. Our investigations reveal strong correspondence between planned and delivered doses shedding light on the dose reliability of OSLD for HT based TBI in-vivo dosimetry.

Autologous hematopoietic stem cell transplantation (auto-HSCT) is the standard of care for patients with diffuse large B-cell lymphoma (DLBCL) who relapse/progress after first line chemoimmunotherapy. Long-term outcome of those who relapse after transplant is poor. We present the results of a retrospective study of 256 adult patients reported to the EBMT registry with DLBCL who relapsed after auto-HSCT performed between 2003 and 2013, and who received active salvage strategies. One hundred and fifty-four (60%) were male; median age was 53 years. Median time to relapse was 7 months, 65% relapsed during the first year. Overall response rate after salvage therapy was 46%. Median follow-up after first salvage therapy was 40 months (IQR 23-63 months). Overall survival (OS) at 3 years was 27% (95% CI 22-33). OS at 3 years of patients relapsing longer than 1 year after auto-HSCT was 41% (95% CI 31-53) compared with 20% (95% CI 14-24) in those who relapsed in less than 1 year. Eighty-two patients (32%) had a second HSCT, an allogeneic HSCT (allo-HSCT) in 69 cases, at a median time of 6.5 months after relapse. OS at 3 years after allo-HSCT was 36% (95% CI 25-51). In conclusion, the prognosis of patients with DLBCL that relapse after auto-HSCT is dismal. Patients who relapse in less than 1 year remain an unmet need, and should be considered for CAR T cell therapy or clinical trials. Patients who relapse after 1 year can be rescued with salvage therapies and a second HSCT. These results provide a benchmark to compare data of new prospective studies.

The International Prognostic Scoring System has been revised (IPSS-R) to predict prognosis of patients with myelodysplastic syndromes at diagnosis. To validate the use of the IPSS-R assessed before transplant rather than at diagnosis we performed a retrospective analysis of the EBMT database. A total of 579 patients had sufficient information available to calculate IPSS-R at transplant. Median overall survival (OS) from transplant was significantly different according to IPSS-R: very low 23.6 months, low 55.0 months, intermediate 19.7 months, high 13.5 months, very high 7.8 months (P<0.001). In a multivariate Cox model the following parameters were significant risk factors for OS: IPSS-R, graft source, age and prior treatment. Median relapse free survival also showed significant differences according to IPSS-R: very low: 23.6 months, low: 24.8 months, intermediate 10.6 months, high 7.9 months, very high 5.5 months (P<0.001). Multivariate risk factors for relapse-free survival (RFS) were: IPSS-R, reduced intensity conditioning, graft source and prior treatment. A trend for an increased relapse incidence was noted for very high risk IPSS-R. We conclude that the IPSS-R at transplant is a useful prognostic score for predicting OS and RFS after transplantation, capturing both disease evolution and response to prior treatment before transplant.

OBJECTIVES: Adult patients with refractory/relapsed ALL have poor survival outcomes with current chemotherapies. We aimed to determine safety and efficacy of lenalidomide, an oral immunomodulator, in these patients. METHODS: This phase 1/2 trial (EUDRACT # 2009-009372-13) included 10 patients who received 28-day cycles of oral lenalidomide 25â mg/day, days 1 through 21, in combination with oral dexamethasone 40â mg/day on days 1, 8, 15, 22. Primary endpoints were tolerance and the overall response rate (ORR). Secondary endpoints included overall survival (OS) and quality of life. RESULTS: The most common grade 3 or 4 adverse events were myelosuppression. The ORR among the participants who could be evaluated was 28.6% (95% confidence interval [CI], 0-62.2%). The median OS was 92 days (range, 43-133 days). All patients have died because of progressive disease. Quality of life remains stable during treatment cycles. DISCUSSION AND CONCLUSION: The safety of combination therapy consisting of lenalidomide plus dexamethasone is consistent with ambulatory administration. Efficacy should be reevaluated in a larger series including patients less intensively previously treated.

BACKGROUND: Patients with follicular lymphoma (FL) relapsing after an autologous transplant (autoSCT) may be treated with a variety of therapies, including a reduced intensity allogeneic transplant (RICalloSCT). We conducted a retrospective analysis of a large cohort of patients undergoing RICalloSCT for FL in this setting. PATIENTS AND METHODS: A total of 183 patients, median age 45 years (range 21-69), had undergone an autoSCT at a median of 30 months before the RICalloSCT. Before the RICalloSCT, they had received a median of four lines (range 3-10) of therapy and 81% of patients had chemosensitive disease and 16% had chemoresistant disease. Grafts were donated from sibling (47%) or unrelated donors (53%). RESULTS: With a median follow-up of 59 months, the non-relapse mortality (NRM) was 27% at 2 years. The median remission duration post-autoSCT and RICalloSCT was 14 and 43 months, respectively. The 5-year relapse/progression rate, progression-free survival and overall survival were 16%, 48% and 51%, respectively, and were associated with age and disease status at RICalloSCT. CONCLUSION: These data suggest that an RICalloSCT is an effective salvage strategy in patients with FL recurring after a prior autoSCT and might overcome the poor prognostic impact of early relapse after autoSCT.
ABSTRACT
Peripheral T-cell lymphoma carries a poor prognosis. To document a possible graft-versus-lymphoma effect in this setting, we evaluated the impact of immunomodulation in 63 patients with peripheral T-cell lymphoma who relapsed after allogeneic transplant in 27 SFGM-TC centers. Relapse occurred after a median of 2.8 months. Patients were then treated with non-immunologic strategies (chemotherapy, radiotherapy) and/or immune modulation (donor lymphocyte infusions (DLI) and/or discontinuation of immunosuppressive therapy). Median overall survival (OS) after relapse was 6.1 months (DLI group: 23.6 months, non-DLI group: 3.6 months). Among the 14 patients who received DLI, 9 responded and 2 had stable disease. Among the remaining 49 patients, a complete response accompanied by extensive chronic GvHD was achieved in two patients after tapering of immunosuppressive drugs. Thirty patients received radio-chemotherapy, with an overall response rate of 50%. In multivariate analysis, chronic GvHD (odds ratio: 11.25 (2.68-48.21), P=0.0009) and skin relapse (odds ratio: 4.15 (1.04-16.50), P=0.043) were associated with a better response to treatment at relapse. In a time-dependent analysis, the only factor predictive of OS was the time from transplantation to relapse (hazards ratio: 0.33 (0.17-0.640), P=0.0009). This large series provides encouraging evidence of a true GvL effect in this disease.

Allogeneic hematopoietic transplantation is increasingly used in patients aged 55 years or more with AML. The question of whether outcomes can be improved with an allele-level 8/8 HLA-matched unrelated donor (MUD) rather than an older HLA-matched sibling (MSD, more than 55 years) is still unanswered. We thus analyzed outcomes in 714 patients aged 55 years and older with AML in first CR (CR1) who received PBSCs after a reduced-intensity conditioning hematopoietic cell transplant from a MUD (n=310) or a MSD (n=404) in a recent period (2005-2010). The 3-year cumulative incidences (CIs) of non-relapse mortality were 17% and 23% with MSD and MUD, respectively (P=0.17). The 3-year CIs of relapse were 37% and 30%, respectively (P=0.12), resulting in a 3-year CI of leukemia-free survival of 46% and 47%, respectively (P=0.51). The 3-year overall survival was 49% with both MSD and MUD. In conclusion, HLA-identical sibling donors aged 55 years or more should not be excluded because of age for patients aged 55 years and older with AML in CR1.

In recipients of allogeneic hematopoietic stem cell transplantation with AML in CR1, reduced intensity (RIC) conditioning regimens are usually given to older patients and myeloablative regimens (MAC) to younger patients. We analyzed whether in middle-aged patients aged 40-60 years, MAC was superior to RIC in cytogenetically higher risk AML. Among 2974 patients, 1638 had MAC and 1336 RIC transplants. Cytogenetics were high risk in 508, intermediate risk in 2297 and low risk in 169. Overall survival (OS) was higher in patients with RIC with low-risk cytogenetics but not in the intermediate- or poor-risk AML. Relapse incidence was lower with MAC in poor- and intermediate-risk AML. Nonrelapse mortality (NRM) was higher in MAC in all cytogenetic risk groups. Multivariate analysis confirmed a significant leukemia-free survival and OS advantage for RIC in low risk but no advantage of MAC in intermediate- and poor-risk leukemia. In patients aged 40-60 years, MAC has no advantage over RIC. We confirm lower relapse but higher NRM risks with MAC. MAC is not superior in patients with higher risk cytogenetics, but is inferior to RIC in the small cohort of AML patients with low-risk cytogenetics.

Allogeneic hematopoietic stem cell transplantation (HSCT) is considered the only a curative treatment in patients with higher risk myelodysplastic syndrome (MDS), although demethylating agents (DMA) have been reported to improve survival. The advantage of HSCT over other treatment comes from retrospective studies and the aim of the current study was to prospectively test this hypothesis, analyzing in particular patients from the pre-transplant period to avoid the selection bias of performing transplantation. This study was conducted to compare overall survival in MDS patients candidates to transplantation according to donor availability. The majority of patients (76%) received a treatment with DMA after registration, 69% had a human leukocyte antigen (HLA)-identical donor, 70% of whom were transplanted. Baseline patient and disease characteristics were similar according to donor availability. Four-year overall survival was significantly better in patients with an HLA matched donor (37%) compared to patients without donor (15%). There was also evidence that this overall survival advantage was because of transplantation. Mortality risk was decreased after transplantation but it became significant only after the second year post transplant, because of early transplant-related mortality. Our results appear to justify, in higher risk MDS, a transplantation approach in all potential candidates who have an HLA identical donor.

BACKGROUND: The aim of this study was to investigate the impact of the high-dose regimen on the outcome of patients with follicular lymphoma (FL) having had autologous stem-cell transplantation (ASCT) in a recent time period. PATIENTS: Between 1995 and 2007, 2233 patients with FL had their first ASCT with either a total body irradiation (TBI)-containing regimen or carmustin, etoposide, cytarabine and melphalan (BEAM), of which 47% were autografted in first remission. RESULTS: After a median observation time of 73 months (interquartile range 30-107), 5- and 10-year non-relapse mortality (NRM) was similar (6% and 10% in both groups). No significant NRM differences became evident after multivariate adjustment for confounders. Secondary malignancies were observed in 9.7% and 7.9% of the patients after TBI and BEAM (P = 0.19), which were treatment-related myelodysplastic syndromes/acute myelogenous leukaemia (t-MDS/AML) in 3.4% and 2.8% (P = 0.57). The median time to t-MDS/AML was around 50 months in both groups. Because of a lower relapse incidence, TBI was associated with better event-free survival reaching statistical significance in the patients transplanted in first remission but not in those transplanted beyond first remission. CONCLUSIONS: In patients with FL who received TBI-based ASCT after 1995 increased NRM and t-MDS/AML risks did not emerge compared with BEAM while disease control was at least equivalent.

WHAT IS KNOWN AND OBJECTIVE: The CHOP regimen with rituximab (R-CHOP) remains the standard for chemotherapy in patients with aggressive non-Hodgkin's lymphoma (NHL). The cardiotoxicity of doxorubicin appears to be a key problem in clinical practice. We studied the cardiotoxicity of CHOP/R-CHOP regimen in a retrospective series. The prognostic factors of congestive heart failure (CHF) were investigated, including the impact of empirical cardioprotection by dexrazoxane. METHODS: Patients with an aggressive NHL between 1994 and 2005 were included. Cardiac events were defined as either a decline in resting left ventricular ejection fraction (LVEF) <50%, a decline in LVEF of ≥20% from baseline or as clinical evidence of CHF. The risk of cardiotoxicity was explored by the Kaplan-Meier method. RESULTS: The study included 180 consecutive patients. During the second period of the survey, cardioprotective therapy by dexrazoxane was administered to 45% of patients. The 5-year cumulative risks of cardiac events (29% vs. 8%) and clinical CHF (17% vs. 1·5%) varied significantly between the two periods of study (1994-2000 vs. 2001-2005). In multivariate analysis, use of dexrazoxane (HR = 0·1 [0·01-0·75], P = 0·02) and age < 60 years (HR = 0·4 [0·17-0·9], P = 0·03) appeared as protective factors of cardiac events. WHAT IS NEW AND CONCLUSION: Our study confirmed the weight of cardiac toxic effect of CHOP ± R regimen. Even if the use of dexrazoxane is highly debatable in curative situations, it may be an effective prevention of cardiotoxicity in aggressive NHL patients.

With broadening indications, more options for hematopoietic cell transplantation (HCT) and improvement in survival, the number of long-term HCT survivors is expected to increase steadily. Infertility is a frequent problem that long-term HCT survivors and their partners face and it can negatively impact on the quality of life. The most optimal time to address fertility issues is before the onset of therapy for the underlying disease; however, fertility preservation should also be addressed before HCT in all children and patients of reproductive age, with referral to a reproductive specialist for patients interested in fertility preservation. In vitro fertilization (IVF) and embryo cryopreservation, oocyte cryopreservation and ovarian tissue banking are acceptable methods for fertility preservation in adult women/pubertal females. Sperm banking is the preferred method for adult men/pubertal males. Frequent barriers to fertility preservation in HCT recipients may include the perception of lack of time to preserve fertility given an urgency to move ahead with transplant, lack of patient-physician discussion because of several factors (for example, time constraints, lack of knowledge), inadequate access to reproductive specialists, and costs and lack of insurance coverage for fertility preservation. There is a need to raise awareness in the medical community about fertility preservation in HCT recipients.

The efficacy of reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT) for Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL) is uncertain. We analyzed 197 adults with Ph+ ALL in first complete remission; 67 patients receiving RIC were matched with 130 receiving myeloablative conditioning (MAC) for age, donor type and HCT year. Over 75% received pre-HCT tyrosine kinase inhibitors (TKIs), mostly imatinib; 39% (RIC) and 49% (MAC) were minimal residual disease (MRD)(neg) pre-HCT. At a median 4.5 years follow-up, 1-year transplant-related mortality (TRM) was lower in RIC (13%) than MAC (36%; P=0.001) while the 3-year relapse rate was 49% in RIC and 28% in MAC (P=0.058). Overall survival (OS) was similar (RIC 39% (95% confidence interval (CI) 27-52) vs 35% (95% CI 27-44); P=0.62). Patients MRD(pos) pre-HCT had higher risk of relapse with RIC vs MAC (hazard ratio (HR) 1.97; P=0.026). However, patients receiving pre-HCT TKI in combination with MRD negativity pre-RIC HCT had superior OS (55%) compared with a similar MRD population after MAC (33%; P=0.0042). In multivariate analysis, RIC lowered TRM (HR 0.6; P=0.057), but absence of pre-HCT TKI (HR 1.88; P=0.018), RIC (HR 1.891; P=0.054) and pre-HCT MRD(pos) (HR 1.6; P=0.070) increased relapse risk. RIC is a valid alternative strategy for Ph+ ALL patients ineligible for MAC and MRD(neg) status is preferred pre-HCT.

Both auto-SCT and reduced intensity allo-SCT (RIST) are employed in the treatment of relapsed follicular lymphoma (FL). We have analysed the outcome of these two transplant procedures when used as a first transplant in this setting. We conducted a retrospective comparison of 726 patients who underwent an auto-SCT and 149 who underwent a RIST as a first transplant procedure for relapsed FL as reported to the Lymphoma Working Party of the European Bone Marrow Transplant. The non-relapse mortality (NRM) was significantly worse for patients undergoing a RIST (relative risk (RR) 4.0, P<0.001). The 1-year NRM was 15% for those undergoing a RIST compared with 3% for those undergoing an auto-SCT. Disease relapse or progression were significantly worse for those receiving an auto-SCT (RR 3.1, P<0.001). Patients undergoing a RIST had a 5-year relapse rate of 20% compared with 47% for those undergoing an auto-SCT. The PFS at 5 years was 57% for patients receiving a RIST compared with 48% for those receiving an auto-SCT. There was no significant difference in OS between the two groups. RIST is associated with a higher NRM and lower relapse rate in patients with relapsed FL.

The mTORC1 signaling pathway is constitutively activated in almost all acute myelogenous leukemia (AML) patients. We conducted a phase Ib trial combining RAD001 (everolimus), an allosteric inhibitor of mTORC1, and conventional chemotherapy, in AML patients under 65 years of age at first relapse (clinical trial NCT 01074086). Increasing doses of RAD001 from 10-70 mg were administrated orally on days 1 and 7 (d1 and d7) of a 3+7 daunorubicin+cytarabine conventional induction chemotherapy regimen. Twenty-eight patients were enrolled in this trial. The treatment was well tolerated with <10% toxicity, mainly involving the gastrointestinal tract and lungs. In this phase Ib trial, the RAD001 maximum tolerated dose was not reached at 70 mg. Sixty-eight percent of patients achieved CR, of which 14 received a double induction. Eight subsequently were intensified with allogeneic-stem cell transplant. Strong plasma inhibition of P-p70S6K was observed after RAD001 administration, still detectable at d7 (d7)at the 70 mg dosage. CR rates in patients with RAD001 areas under or above the curve median were 53% versus 85%. A 70 mg dose of RAD001 at d1 and d7 of an induction chemotherapy regimen for AML has acceptable toxicity and may improve treatment.

Childhood autologous hematopoietic cell transplant (auto-HCT) survivors can be at risk for secondary malignant neoplasms (SMNs). We assembled a cohort of 1487 pediatric auto-HCT recipients to investigate the incidence and risk factors for SMNs. Primary diagnoses included neuroblastoma (39%), lymphoma (26%), sarcoma (18%), central nervous system tumors (14%) and Wilms tumor (2%). Median follow-up was 8 years (range, <1-21 years). SMNs were reported in 35 patients (AML/myelodysplastic syndrome (MDS)=13, solid cancers=20, subtype missing=2). The overall cumulative incidence of SMNs at 10 years from auto-HCT was 2.60% (AML/MDS=1.06%, solid tumors=1.30%). We found no association between SMNs risk and age, gender, diagnosis, disease status, time since diagnosis or use of TBI or etoposide as part of conditioning. OS at 5-years from diagnosis of SMNs was 33% (95% confidence interval (CI), 16-52%). When compared with age- and gender-matched general population, auto-HCT recipients had 24 times higher risks of developing SMNs (95% CI, 16.0-33.0). Notable SMN sites included bone (N=5 SMNs, observed (O)/expected (E)=81), thyroid (N=5, O/E=53), breast (N=2, O/E=93), soft tissue (N=2, O/E=34), AML (N=6, O/E=266) and MDS (N=7, O/E=6603). Risks of SMNs increased with longer follow-up from auto-HCT. Pediatric auto-HCT recipients are at considerably increased risk for SMNs and need life-long surveillance for SMNs.

BACKGROUND: Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, acquired, clonal haemopoietic stem cell disorder that causes chronic intravascular haemolysis, increases the risk of thrombosis and results in significant patient morbidity and mortality. The symptoms of PNH may have a major impact on patient quality of life. AIMS: To assess patient fatigue and health-related quality of life in 29 patients with PNH using the Functional Assessment of Chronic Illness Therapy Fatigue subscale version 4 (FACIT-Fatigue) and the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire-C30, version 3 (EORTC QLQ-C30). METHODS: Following completion of the questionnaires, patients were interviewed to assess the validity, clarity, relevance and comprehensiveness of the assessments. RESULTS: Overall, patients considered both the FACIT-Fatigue and EORTC QLQ-C30 instruments to be relevant and adequate in assessing the level of PNH-associated fatigue and other quality-of-life measures. The FACIT-Fatigue questionnaire was considered to be clear and to comprehensively cover PNH-related fatigue. The EORTC QLQ-C30 instrument was considered to be easy to understand, but of an overall lower relevance, although some differences between countries were observed. Patients suggested additional questions that could be incorporated into future EORTC QLQ-C30 versions to make it more relevant to PNH. CONCLUSIONS: This study confirms the validity of the FACIT-Fatigue and the EORTC QLQ-C30 questionnaires in this patient population and their routine use should be considered in the management of patients with PNH.
