Maintain Efficacy and Spare Toxicity: Traditional and New Radiation-Based Conditioning Regimens in Hematopoietic Stem Cell Transplantation. Cancers (Basel) 2024; 16:865.

Abstract
Novelty in total body irradiation (TBI) as part of pre-transplant conditioning regimens lacked until recently, despite the developments in the field of allogeneic stem cell transplants. Long-term toxicities have been one of the major concerns associated with TBI in this setting, although the impact of TBI is not so easy to discriminate from that of chemotherapy, especially in the adult population. More recently, lower-intensity TBI and different approaches to irradiation (namely, total marrow irradiation, TMI, and total marrow and lymphoid irradiation, TMLI) were implemented to keep the benefits of irradiation and limit potential harm. TMI/TMLI is an alternative to TBI that delivers more selective irradiation, with healthy tissues being better spared and the control of the radiation dose delivery. In this review, we discussed the potential radiation-associated long-term toxicities and their management, summarized the evidence regarding the current indications of traditional TBI, and focused on the technological advances in radiotherapy that have resulted in the development of TMLI. Finally, considering the most recent published trials, we postulate how the role of radiotherapy in the setting of allografting might change in the future.

Abstract
The FLAMSA reduced intensity (RIC) concept, also known as "sequential therapy", is a conceptual platform for the treatment of leukemia separated in several parts: induction therapy, a sequence of antileukemic and immunosuppressive conditioning for allogeneic stem cell transplantation, and immune restitution supported by donor lymphocyte transfusions. The antileukemic part consists of fludarabine, cytosine arabinoside, and amsacrine (FLAMSA); non-cross reactive agents like fludarabine and amsacrine have been successfully used in cases of refractoriness and relapse. Immunosuppressive conditioning and transplantation follow after only 3 days of rest. This way, the toxicity of allogeneic transplantation could be reduced and the anti-leukemia effects by using allogeneic immune cells could be optimized. This review summarizes available data on efficacy and toxicity of this approach. Further, possible strategies for improvements are discussed in order to provide better chances for elderly and frail patients and patients with advanced and high-risk disease. Among others, several new agents are available that target molecular changes of leukemia for induction of remission and allow for bridging the time after transplantation until adoptive immunotherapy becomes safe and effective.

Abstract
The remarkable clinical activity of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia (CML) has transformed patient outcome. Consequently, allogeneic stem cell transplantation (allo-SCT) is no longer the only treatment modality with the ability to deliver long-term survival. In contrast to the central position it held in the treatment algorithm 20 years ago, allografting is now largely reserved for patients with either chronic-phase disease resistant to TKI therapy or advanced-phase disease. Over the same period, progress in transplant technology, principally the introduction of reduced intensity conditioning regimens coupled with increased donor availability, has extended transplant options in patients with CML whose outcome can be predicted to be poor if they are treated with TKIs alone. Consequently, transplantation is still a vitally important, potentially curative therapeutic modality in selected patients with either chronic- or advanced-phase CML. The major causes of transplant failure in patients allografted for CML are transplant toxicity and disease relapse. A greater understanding of the distinct contributions made by various factors such as patient fitness, patient-donor HLA disparity, conditioning regimen intensity, and transplant toxicity increasingly permits personalized transplant decision making. At the same time, advances in the design of conditioning regimens coupled with the use of adjunctive posttransplant cellular and pharmacologic therapies provide opportunities for reducing the risk of disease relapse. The role of SCT in the management of CML will grow in the future because of an increase in disease prevalence and because of continued improvements in transplant outcome.

Abstract
The management of chronic myeloid leukaemia (CML) has changed extensively over the past 15 years. Prior to the development of targeted therapies and in the absence of allogeneic haematopoetic stem-cell transplantation (HSCT), the median survival was 5-7 years. HSCT was quickly established as the standard of care for eligible patients through the 1980s and 1990s, when considerable advances were made in the optimization of conditioning regimens and supportive care. Exploiting a deeper understanding of the molecular basis of CML, the development of tyrosine kinase inhibitors (TKIs) in the late 1990s revolutionized the management of the disease. TKIs offer the prospect of long-term disease control with a simple oral therapy, and are the first-line treatment in the 21(st) century. The majority of patients treated with TKIs achieve excellent responses with sustained treatment, and some even continue to have undetectable or exceptionally low level disease upon TKI withdrawal; however, for an almost equal number of patients, an adequate response cannot be achieved with any of the currently available TKIs. For those patients who fail to respond adequately to TKIs, HSCT offers the best prospect of long-term survival.

Abstract
Hematopoietic stem cell transplantation (HCT) utilizing non-myeloablative (NMA) and reduced-intensity conditioning (RIC) regimens (collectively referred to as reduced-toxicity HCT, RT-HCT) has become a viable therapeutic option for patients with hematological malignancies who are ineligible for standard myeloablative conditioning transplantation (MA-HCT). RT-HCT has been shown to induce stable engraftment with low toxicity, and to produce similar overall and progression-free survival (PFS) when compared to MA-HCT in acute myeloid leukemia and myelodysplastic syndrome. The best results for RT-HCT have been reported for patients with disease that is in remission, indolent and chemosensitive, and with a strong graft-versus-malignancy effect. Chronic graft-versus-host disease seems to correlate with a lower relapse rate and better PFS. RT-HCT is inferior when performed in poor risk or advanced disease, due to high relapse rates. A search for novel strategies that includes the most appropriate conditioning regimens and post-transplant immunomodulation protocols with more intensive anti-malignancy activity but limited toxicity is in progress. This review provides an update on the results of clinical studies of RT-HCT, and discusses possible indications and investigative strategies for improving the clinical outcomes of RT-HCT for the major hematological malignancies.

Abstract
In the pre-tyrosine kinase (TKI) era, allogeneic stem cell transplant (allo-SCT) was the front-line treatment of choice for young patients with chronic myelogenous leukemia (CML). Today, imatinib is well established as front-line therapy for CML, with excellent long-term outcomes. This has changed the role of allo-SCT and the number of patients undergoing allo-SCT has declined dramatically. Allo-SCT is currently recommended for patients in accelerated/blast phase disease, those who have failed a second-generation TKI and those with TKI-resistant mutations such as T315I. The role of allo-SCT in the management of CML will require continual reappraisal as medical therapies continue to evolve.

Abstract
BACKGROUND The prevalence and features of graft-versus-host disease (GVHD) in patients receiving allografts using peripheral blood stem cells (PBSCs) after a reduced-intensity conditioning (RIC) regimen are not well known. Several features of GVHD in patients at two institutions using RIC were assessed. METHODS We analysed the overall survival (OS) and prevalence of GVHD in patients who underwent outpatient allogeneic PBSC transplantation after RIC between October 1998 and July 2008. RESULTS We included 301 patients with a median age of 30 yrs (range, 1-71 yrs). In 37 cases, allogeneic peripheral blood stem cell transplantation was indicated for non-malignant disease, and in 264 for malignant disease. The median OS was 35 months. The estimated 3-yr OS was 48%. A total of 154 patients developed GVHD: there were 64 acute, 50 chronic and 40 cases that progressed from acute to chronic. Of the 104 patients with acute GVHD (aGVHD), 40% had grade I and 60% had grades II-IV. Of the 90 patients with chronic GVHD (cGVHD), 67% had limited and 33% had extensive forms. A total of 160 patients died, 40 as a result of GVHD (24 from aGVHD and 16 from cGVHD), 50 as a result of progressive disease and 70 from diverse causes. CONCLUSIONS The incidence of GVHD was lower than in other series using conventional myeloablative preparative regimens. Most importantly, the severity of GVHD did not significantly affect the long-term survival.

Abstract
The myeloproliferative neoplasms (MPNs) are a group of clonal disorders that arise from a pluripotent hematopoietic stem cell and are characterized by excess cellular proliferation. These disorders tend to be chronic in nature and can terminate over time into a bone marrow failure syndrome characterized by marrow fibrosis or transform into a leukemic phase. MPNs are predominantly diseases of the elderly and this is one reason why until very recently the standard treatment was supportive care. The only curative modality for these disorders is allogeneic hematopoietic cell transplantation. The introduction of reduced-intensity conditioning regimens now allows this life-saving therapy to be offered to elderly patients who were previously considered ineligible for high-dose conditioning owing to age or comorbidity. In this review, we will summarize the current strategies and future directions regarding the use of reduced-intensity conditioning regimens in the treatment of MPNs.

Abstract
To determine the impact of imatinib therapy prior to allogeneic stem-cell transplantation in advanced stage chronic myelogenous leukaemia (CML), 30 CML patients who had received imatinib as part of pre-transplant treatment were analysed, with special emphasis on the cytogenetic response to imatinib therapy shortly before transplantation. Median patient age was 51 years (range, 24 - 64). At the time of transplantation all patients were in second or higher chronic phase (CP). The median follow-up after allogeneic transplantation was 360 days (range, 24 - 1524). Cox regression analysis revealed that the quality of cytogenetic response was a prognostic factor for transplant-related mortality (p = 0.050), relapse incidence (p = 0.015), leukaemia-free survival (p = 0.002) and overall survival (p = 0.006). A cytogenetic response with <35%BCR-ABL-positive interphase nuclei in FISH analysis from bone marrow was associated with a probability of overall survival of 81% at 3 years. In conclusion, our data suggest that advanced stage CML has an excellent outcome after allogeneic haematopoietic stem-cell transplantation when transplanted in the phase of cytogenetic response to imatinib.

Abstract
Fludarabine and 200 cGy TBI are commonly used for reduced-intensity conditioning preceding allogeneic hematopoietic SCT (HSCT). However, graft rejection and disease relapse are significant causes of treatment failure with this regimen. We modified this regimen by escalating the TBI dose to 400 cGy in 40 patients with hematologic malignancies. Thirty-four patients achieved complete donor T-cell chimerism at a median of 40 days following HSCT. The incidences of grades II-IV and III-IV acute GVHD were 40 and 15%, respectively, whereas that of limited and extensive chronic GVHD were 12 and 20%, respectively. Two patients rejected their grafts and 12 relapsed. The 100-day mortality was 18%, 2-year transplant-related mortality 20% and overall survival was 58% at a median follow-up of 16 months. There were no significant survival differences between patients with lymphoid compared to myeloid malignancies. A dose of 400 cGy TBI administered with fludarabine is well tolerated and further study is needed to determine whether outcomes are superior to those with 200 cGy TBI.

Abstract
Chronic myeloid leukaemia (CML) was the first neoplastic disease for which knowledge of the genotype led to a rationally designed therapy. As a result of its well known pathophysiology, straightforward diagnosis, well established prognostic factors, and treatment for the cause of disease, CML has been studied to an extent that far exceeds that expected from its frequency, and serves as a model disease for other cancers. Imatinib, an inhibitor of BCR-ABL tyrosine kinase, has revolutionised treatment of this disease, and is now recommended as standard treatment for chronic-phase CML. Interferon alfa is an acceptable alternative treatment in the early chronic phase for patients who do not tolerate imatinib. If imatinib treatment fails, allogeneic stem-cell transplantation, a dose increase of imatinib, or new drugs are recommended. Up to 87% of patients achieve complete cytogenetic remission, therefore we provide guidance for monitoring disease status. Many trials of new drugs and combination therapies that include imatinib are underway.

Abstract
Although it is now generally accepted that imatinib is the best initial treatment for patients newly diagnosed with chronic myeloid leukemia (CML) in chronic phase, a number of questions remain unanswered. For example, (1) Is imatinib the best initial treatment for every chronic-phase patient? (2) At what dose should imatinib be started? (3) How should response to treatment be monitored? (4) For how long should the drug be continued in patients who have achieved and maintain a complete molecular response? (5) How does one handle a patient who achieves a 2-log but not a 3-log reduction in BCR-ABL transcripts? (6) How should response or failure be defined? (7) For the patient deemed to have failed imatinib, should one offer dasatinib or nilotinib? (8) For the patient who has failed imatinib but has a possible allogeneic transplant donor, should one offer dasatinib or nilotinib before recommending a transplantation? (9) Should the transplantation be myeloablative or reduced intensity conditioning? (10) How should one treat the patient who relapses after allografting? This paper will address these issues, many of which cannot yet be answered definitively.

Abstract
Allogeneic hematopoetic stem cell transplantation (HSCT) is still the only curative therapeutic option for chronic myelogenous leukemia (CML). To examine the development of allogeneic HSCT at our center over the past two decades (decade 1: 1984-1994; decade 2: 1995-2005), all CML patients transplanted in first chronic phase (n = 234) were analyzed with respect to patient characteristics, overall survival, transplant-related mortality (TRM), and relapse incidence. The median follow up time was 54 months (range 1-218). The incidence of acute graft vs host disease (GvHD) degrees II-IV and extensive chronic GvHD were not different between the two decades (p = 0.894 and p = 0.422, respectively). There was also no difference in the relapse incidence (23 vs 26%, p = 0.869). One-year TRM and overall survival were improved in the later decade (33 vs 18%, p = 0.011 and 62 vs 73% at 5 years, p = 0.063, respectively). The major reason for improved outcome in decade 2 was the improved management of acute GvHD and infections in the early phase after transplantation (p = 0.026). In conclusion, the past decade has seen significant improvement in the performance of allogeneic HSCT for CML.

Abstract
Numerous reduced-intensity conditioning regimens for allogeneic hematopoietic cell transplantation are currently being explored, primarily in older patients and in individuals with comorbid conditions who are not eligible for conventional myeloablative conditioning regimens. There is agreement that these approaches have reduced early transplant-related (non-relapse) toxicity and mortality. It is unclear, however, whether these strategies improve long-term survival. Furthermore, as most trials with reduced-intensity regimens have enrolled older patients and patients with comorbid conditions, it is not appropriate to compare the results of these trials to those obtained with more conventional approaches. It remains to be determined whether younger patients, and patients without comorbid conditions, will derive significant long-term benefits from reduced-intensity regimens when compared to conventional strategies. It may be that the different approaches are complementary and in the end will preferentially serve specific patient populations based on age, comorbid conditions and malignancy type. To determine the role of reduced-intensity approaches, controlled prospective trials are needed, with enrolled patients being stratified according to comorbid conditions, disease characteristics, pre-transplant therapy and source of stem cells, at a minimum.

Abstract
The realization in the 1990s that allogeneic stem cell transplants (SCT) have a potentially curative graft-versus-leukemia (GVL) effect in addition to the antileukemic action of myeloablative conditioning regimens was a major stimulus for the development of reduced-intensity conditioning (RIC) regimens, aimed primarily at securing engraftment to provide the GVL effect, while minimizing regimen-related toxicity. It is now over 10 years since RIC regimens were heralded as a new direction in the field of SCT. Over the last decade much has been learned about the ways in which the conditioning regimen can be tailored to provide adequate immunosuppression, and modulated to deliver a chosen degree of antimalignant treatment. The huge literature of clinical data with RIC transplantation now permits us to more clearly define the success and limitations of the approach. This review examines the origins of RIC SCT, explores the degree to which the initial expectations and purpose of the approach have been realized, and outlines some ways forward for the field.

Abstract
Host conditioning prior to allogeneic bone marrow transplantation (BMT) has traditionally involved the use of high-dose, myeloablative chemotherapy and irradiation, focusing on maximal tumor cytoreduction as well as adequate immunosuppression to allow engraftment of allogeneic stem cells. High-dose chemoradiation conditioning regimens have been associated with a significant incidence of organ toxicity and acute and chronic graft-versus-host disease (GVHD). Recent efforts to diminish the acute transplant-associated toxicities have focused on the development of relatively nontoxic, nonmyeloablative, or less myeloablative conditioning regimens, with the emphasis being predominantly on induction of immunosuppression to enable engraftment. Without ablative chemotherapy, disease control in these regimens is largely relegated to the graft-versus-leukemia/lymphoma (GVL) effect. While the evolution these regimens has resulted in successful engraftment of allogeneic stem cells with minimal toxicity, acute and chronic GVHD occurs in 20% to 50% of patients and remains a major cause of transplant-associated morbidity. Strategies to lower the incidence of acute GVHD have primarily focused on more precise molecular donor/recipient matching, alternative stem cell sources, and T-cell depletion of the graft. While successful in lowering the frequency and severity of GVHD, T-cell-depleted grafts have been associated with compromised the graft-versus-disease effect. Recent studies have suggested that, in addition to T-effector cells within the graft, donor and host dendritic cells may play a role in GVHD. Purine analogues have been evaluated as part of these regimens. While fludarabine and cladribine have been shown to be effective, these agents have been associated with an increased incidence of serious infection and severe acute GVHD. Pentostatin has a different mechanism of action and was also investigated as part of these preparative regimens. Regimens using pentostatin/extracorporeal photopheresis (ECP)/total body irradiation (TBI) have been shown to be well tolerated and associated with early full donor engraftment with a predominance of donor dendritic cell (DC)2 cells and a low incidence of acute GVHD. Further investigation evaluating this preparative regimen is warranted.

Abstract
Using a reduced-intensity stem cell transplantation (RIST) schedule, 24 patients with Philadelphia (Ph1) (+) chronic myelogenous leukemia (CML) in first chronic phase (CP) were prospectively allografted in four Latin American countries: México, Brazil, Colombia and Venezuela, using HLA-identical siblings as donors. The median age of the patients was 41 years (range 10-71 years); there were eight females. Patients received a median of 4.4 x 10(6)/kg CD34 cells. The median time to achieve above 0.5 x 10(9)/l granulocytes was 12 days, range 0-41 days, and the median time to achieve above 20 x 10(9)/l platelets was also 12 days, range 0-45 days. In all, 22 patients are alive 81-830 (median 497) days after RIST. The 830-day probability of survival is 92%, and the median survival has not been reached, being beyond 830 days. A total of 11 patients (46%) developed acute graft-versus-host disease (GVHD), and seven of 23 (30%) developed chronic GVHD. Two patients died 43 and 210 days after RIST, one as a result of sepsis and the other of chronic GVHD. The 100-day mortality was 4.4%, and transplant-related mortality was 8%. RIST for patients with CML in CP appears to be an adequate therapeutic option.

Abstract
Hematopoietic stem cell transplantation has been a cornerstone of therapy for chronic myelogenous leukemia (CML) for more than 15 years and is still a standard treatment option for patients with CML. The advent of imatinib mesylate, an inhibitor of the molecular defect driving CML, the BCR-ABL tyrosine kinase, has rewritten treatment algorithms for this disease and has shifted focus away from allografting. Despite advances in stem cell transplantation, such as broader availability with the use of modified conditioning regimens, use of allografting has diminished. Also, the nearly universal patient exposure to imatinib or other kinase inhibitors before transplantation may affect the biology of the disease that is currently being treated with an allograft and ultimately may affect outcomes. Exceedingly high rates of meaningful and stable response with longer follow-up continue to drive enthusiasm for imatinib use, and understanding of resistance mechanisms has driven rapid investigation of second-generation tyrosine kinase inhibitors to address imatinib failure and suboptimal response. In most patients, imatinib reduces CML to a minimal residual disease state in which options to further deepen remission, such as immunotherapy, are sought; monitoring techniques and interpretation of response advance in parallel to meet demands; and uncertainty remains as a new natural history of CML is defined in an era of kinase inhibitor therapy. This review summarizes the state of transplant and nontransplant therapy for CML and discusses the decision making for patients with an aim to optimize the use of our best therapies for CML in an era of uncertainty.

Abstract
Abstract
Although the only curative therapy for chronic myeloid leukemia remains allogeneic stem cell transplantation (allo-SCT), early to mid-term results of imatinib in newly diagnosed patients are sufficiently impressive to have displaced allo-SCT to second- or third-line treatment. Patients now arrive at a decision for transplantation in a variety of disease situations: failing to achieve certain hematological, cytogenetic and molecular milestones by some pre-determined timepoint, having lost a previous best response or by progression to advanced phase. The decision, therefore, is not simply whether to transplant or not, but also how to transplant. Evolving transplant technology requires that the individual circumstances of each patient should be considered when recommending the procedure. Attempts to improve the safety of transplant are generally associated with a reduction in long-term disease control and patient monitoring, and management is life-long. The treatment of recurrent disease is no longer straightforward, with the choices being donor lymphocytes or tyrosine kinase inhibitors alone or in combination. This section will review the evidence supporting some of these decisions and highlight current controversies.

Abstract
Management of patients with chronic myeloid leukemia has become increasingly difficult over the last few years since there are a variety of treatment options available. The ultimate challenge is to decide the most appropriate treatment strategy for an individual patient. To facilitate this, assessment of an individual patient's disease in terms of status, tempo and response to initial treatment needs to be determined. This review article discusses the current treatment options in the management of chronic myeloid leukemia, the factors that influence management decisions and suggests how treatment for the individual patient may be tailored whilst involving the patient in the decision-making process.
