Policy
Allogeneic hematopoietic cell transplantation (HCT) using a myeloablative conditioning regimen may be considered medically necessary to treat:
- Poor- to intermediate-risk acute myeloid leukemia (AML) in first complete remission (CR1) (see Policy Guidelines for risk stratification); or
- AML that is refractory to standard induction chemotherapy, but can be brought into CR with intensified induction chemotherapy; or
- AML that relapses following chemotherapy-induced CR1 but can be brought into CR2 or beyond with intensified induction chemotherapy; or
- AML in individuals who have relapsed following a prior autologous HCT, but can be brought into CR with intensified induction chemotherapy and are medically able to tolerate the procedure.
Allogeneic HCT using a reduced-intensity conditioning regimen may be considered medically necessary as a treatment of AML in individuals who are in complete marrow and extramedullary remission (CR1 or beyond) and who for medical reasons would be unable to tolerate a myeloablative conditioning regimen (see Policy Guidelines).
Autologous HCT may be considered medically necessary to treat AML in CR1 or beyond, or relapsed AML, if responsive to intensified induction chemotherapy in individuals who are not candidates for allogeneic HCT.
Allogeneic and autologous HCT are investigational in individuals not meeting any of the above criteria, as there is insufficient evidence to support a general conclusion concerning the health outcomes or benefits associated with this procedure.
Policy guidelines
Primary refractory acute myeloid leukemia (AML) is defined as leukemia that does not achieve a complete remission after conventionally dosed (non-marow ablative) chemotherapy.
In the French-American-British criteria, the classification of AML is based solely on morphology as determined by the degree of differentiation along different cell lines and the extent of cell maturation.
Clinical features that predict poor outcomes of AML therapy include, but are not limited to, the following:
- Treatment-related AML (secondary to prior chemotherapy and/or radiotherapy for another malignancy)
- AML with antecedent hematologic disease (e.g., myelodysplasia)
- Presence of circulating blasts at the time of diagnosis
- Difficulty in obtaining first complete remission with standard chemotherapy
- Leukemias with monocytic differentiation (French-American-British classification M4 or M5)
The newly preferred World Health Organization (WHO) classification of AML incorporates and interrelates morphology, cytogenetics, molecular genetics, and immunologic markers in an attempt to construct a classification that is universally applicable and prognostically valid. The WHO system was adopted by the National Comprehensive Cancer Network (NCCN) to estimate individual prognosis to guide management, as shown in Table PG1.

AML: acute myeloid leukemia; ITD: internal tandem duplication.
The relative importance of cytogenetic and molecular abnormalities in determining prognosis and guiding therapy is under investigation.
The ideal allogeneic donors are human leukocyte antigen (HLA)–identical siblings, matched at the HLA-A, -B, and -DR (antigen-D related) loci on each arm of chromosome 6. Related donors mismatched at one locus are also considered suitable donors. A matched, unrelated donor identified through the National Marrow Donor Registry is typically the next option considered.
Recently, there has been interest in haploidentical donors, typically a parent or a child of the individual for which there is usually sharing of only 3 of the 6 major histocompatibility antigens. Most individuals will have such a donor; however, the risk of graft-versus-host disease and overall morbidity with these donors is generally higher than with matched donors.

Description/background
Acute myeloid leukemia
Acute myeloid leukemia (AML) refers to leukemias that arise from a myeloid precursor in the bone marrow. There is a high incidence of relapse, which has prompted research into various post-remission strategies using either allogeneic (allo-) or autologous hematopoietic cell transplantation (HCT). Hematopoietic cell transplantation refers to a procedure that infuses hematopoietic stem cells to restore bone marrow function in individuals with cancer who receive bone marrow-toxic doses of drugs with or without whole-body radiotherapy.
Treatment
Complete remission of AML can be achieved initially using induction therapy, consisting of conventional doses of combination chemotherapy. A complete response is achieved in 60% to 80% of adults younger than 60 years of age and in 40% to 60% in individuals older than 60 years of age. However, the high incidence of disease relapse has prompted research into a variety of post-remission (consolidation) strategies using high-dose chemotherapy with autologous HCT or high-dose or reduced-intensity chemotherapy with allogeneic HCT (allo-HCT).
The 2 treatments, autologous HCT and allo-HCT, represent 2 different strategies. The first, autologous HCT, is a “rescue,” but not a therapeutic procedure; the second, allo-HCT, is a “rescue” plus a therapeutic procedure.
Hematopoietic cell transplantation
HCT is a procedure in which hematopoietic stem cells are intravenously infused to restore bone marrow and immune function in cancer patients who receive bone marrow-toxic doses of cytotoxic drugs with or without whole-body radiotherapy. Hematopoietic stem cells may be obtained from the transplant recipient (autologous HCT) or a donor (allo-HCT). These cells can be harvested from bone marrow, peripheral blood, or umbilical cord blood shortly after delivery of neonates. Cord blood is discussed in detail in evidence review MP 9.001.
Immunologic compatibility between infused hematopoietic stem cells and the recipient is not an issue in autologous HCT. In allo-HCT, immunologic compatibility between donor and patient is a critical factor for achieving a successful outcome. Compatibility is established by typing of human leukocyte antigens (HLAs) using cellular, serologic, or molecular techniques. HLA refers to the gene complex expressed at the HLA-A, -B, and -DR (antigen-D related) loci on each arm of chromosome 6. An acceptable donor will match the patient at all or most of the HLA loci.
Conventional conditioning for HCT
The conventional (“classic”) practice of allo-HCT involves administration of cytotoxic agents (e.g., cyclophosphamide, busulfan) with or without total body irradiation at doses sufficient to cause bone marrow ablation in the recipient. The beneficial treatment effect of this procedure is due to a combination of initial eradication of malignant cells and subsequent graft-versus-malignancy (GVM) effect mediated by non-self immunologic effector cells. While the slower GVM effect is considered the potentially curative component, it may be overwhelmed by existing disease in the absence of pretransplant conditioning.
Intense conditioning regimens are limited to patients who are sufficiently medically fit to tolerate extensive damage of other tissues such as end-organ damage or failure caused by cytotoxic drugs. Subsequent to graft infusion in allo-HCT, immunosuppressant drugs are required to minimize graft rejection and graft-versus-host disease (GVHD), which increases susceptibility to opportunistic infections.
The success of autologous HCT is predicated on the potential of cytotoxic chemotherapy, with or without radiotherapy, to eradicate cancerous cells from the blood and bone marrow. This permits subsequent engraftment and repopulation of bone marrow with hematopoietic stem cells obtained from the patient before undergoing bone marrow ablation. Therefore, autologous HCT is typically performed as consolidation therapy when the patient’s disease is in complete remission. Patients who undergo autologous HCT are susceptible to chemotherapy-related toxicities and opportunistic infections before engraftment, but not GVHD.
Reduced-intensity conditioning for allo-HCT
Reduced-intensity conditioning (RIC) refers to the pretransplant use of lower doses of cytotoxic drugs or less intense regimens of radiotherapy than are used in traditional full-dose myeloablative conditioning (MAC) treatments. Although the definition of RIC is variable, with numerous versions employed, all regimens seek to balance the competing aspects of relapse and non-relapse mortality.
The goal of RIC is to reduce morbidity and non-relapse mortality during the period in which the beneficial graft-versus-malignancy effect of allogeneic transplantation develops. Reduced-intensity conditioning regimens range from nearly total myeloablative to minimally myeloablative with lymphoablation, with intensity tailored to specific diseases and patient condition. Patients who undergo RIC with allo-HCT initially demonstrate donor cell engraftment and bone marrow mixed chimerism. Most will subsequently convert to full-donor chimerism. In this review, the term reduced-intensity conditioning will refer to all conditioning regimens intended to be nonmyeloablative.
A 2015 review in the New England Journal of Medicine summarized advances in the classification of AML, the genomics of AML and prognostic factors, and current and new treatments. The National Comprehensive Cancer Network guidelines provide updated information on genetic markers for risk stratification, and additional recent reviews summarize information on novel therapies for AML.
Regulatory status
The U.S. Food and Drug Administration regulates human cells and tissues intended for implantation, transplantation, or infusion through the Center for Biologics Evaluation and Research, under Code of Federal Regulation, Title 21, parts 1270 and 1271. Hematopoietic stem cells are included in these regulations.
Rationale
Summary of evidence
For individuals who have cytogenetic or molecular intermediate- or poor-risk AML in first complete remission (CR1) who receive allo-HCT with myeloablative conditioning, the evidence includes systematic reviews, randomized controlled trials, and matched cohort studies. Relevant outcomes are overall survival, disease-specific survival, and treatment-related mortality and morbidity. The majority of the evidence suggests that allo-HCT is better at improving overall and disease-free survival than consolidation chemotherapy. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.
For individuals who have AML refractory to standard induction chemotherapy who receive allo-HCT with myeloablative conditioning, the evidence includes retrospective data comparing patients entered into phase 3 trials and registry databases. The evidence suggests that allo-HCT improves overall survival and disease-specific survival in patients refractory to induction chemotherapy better than conventional chemotherapy. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.
For individuals who have AML who relapse after standard induction chemotherapy-induced CR1 who receive allo-HCT or autologous HCT with MAC, the evidence includes retrospective studies and registry data. Relevant outcomes are overall survival and disease-specific survival. The evidence shows that allo-HCT improves survival outcomes compared with conventional chemotherapy. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.
For individuals who have cytogenetic or molecular intermediate- or poor-risk AML in CR1 and for medical reasons cannot tolerate MAC who receive allo-HCT with reduced-intensity conditioning (RIC), the evidence includes randomized controlled trials, meta-analyses, and other comparative studies. The evidence indicates that RIC results are similar to MAC in relapse mortality, relapse, and overall survival, although some trials were stopped prematurely. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.
For individuals who have AML in CR1 or beyond without a suitable allo-HCT donor who receive autologous HCT, the evidence includes prospective cohort studies and randomized trials comparing autologous HCT with chemotherapy. Relevant outcomes are overall and disease-free survival. Autologous HCT reduces relapse rates and improves disease-free survival, though overall survival does not differ significantly. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.
Definitions
Relapsed refers to patients who have achieved remission but later have decreased numbers of normal blood cells and a return of leukemia in their bone marrow.
Refractory refers to patients who have residual leukemia cells in their bone marrow even after they receive intensive treatment.
