Hematopoietic Cell Transplantation for Acute Lymphoblastic Leukemia
Policy Number: MP-414
Latest Review Date: January 2024
Category: Surgery
POLICY:
Childhood Acute Lymphoblastic Leukemia
Allogeneic or autologous hematopoietic cell transplantation (HCT) may be considered medically necessary to treat childhood acute lymphoblastic leukemia (ALL) in first complete remission but at high risk of relapse. (For definition of high-risk factors, see Description section).
Autologous or allogeneic HCT may be considered medically necessary to treat childhood ALL in second or greater remission or refractory ALL.
Allogeneic HCT may be considered medically necessary to treat relapsing ALL after a prior autologous HCT.
Adult Acute Lymphoblastic Leukemia
Autologous HCT may be considered medically necessary to treat adult ALL in first complete remission but at high risk of relapse. (For definition of high-risk factors, see Description section).
Allogeneic HCT may be considered medically necessary to treat ALL in first complete remission for any risk level (for definition of risk factors, see Description section).
Allogeneic HCT may be considered medically necessary to treat adult ALL in second or greater remissions, or in individuals with relapsed or refractory ALL.
Allogeneic HCT may be considered medically necessary to treat relapsing ALL after a prior autologous HCT.
Reduced-intensity conditioning allogeneic HCT may be considered medically necessary as a treatment of ALL in individuals who are in complete marrow and extramedullary first or second remission, and who, for medical reasons would be unable to tolerate a standard myeloablative conditioning regimen.
Autologous HCT is considered investigational to treat adult ALL in second or greater remission or those with refractory disease.
POLICY GUIDELINES:
Relapse Risk Prognostic Factors
Childhood Acute Lymphoblastic Leukemia
Adverse prognostic factors in children include the following: age younger than 1 year or more than 9 years, male gender, white blood cell count at presentation above 50,000/μL, hypodiploidy (<45 chromosomes), translocation involving chromosomes 9 and 22 (t[9;22]) or BCR/ABL fusion, t(4;11) or MLL/AF4 fusion, and ProB or T-lineage immunophenotype.
Several risk-stratification schema exist, but, in general, the following findings help define children at high risk of relapse: (1) poor response to initial therapy including poor response to prednisone prophase defined as an absolute blast count of 1000/μL or greater, or poor treatment response to induction therapy at 6 weeks with high risk having ≥1% minimal residual disease measured by flow cytometry; (2) all children with T-cell phenotype; and (3) individuals with either the t(9;22) or t(4;11) regardless of early response measures.
Adult Acute Lymphoblastic Leukemia
Risk factors for relapse are less well-defined in adults, but an individual with any of the following may be considered at high risk for relapse: age older than 35 years, leukocytosis at presentation of greater than 30,000/μL (B-cell lineage) or greater than 100,000/μL (T-cell lineage), “poor prognosis” genetic abnormalities like the Philadelphia chromosome (t[9; 22]), extramedullary disease, and time to attain complete remission longer than 4 weeks.
Reduced Intensity Conditioning
Some individuals for whom a conventional myeloablative allogeneic HCT could be curative may be considered candidates for reduced-intensity conditioning allogeneic HCT. Such individuals include those whose age (typically >60 years) or comorbidities (e.g., liver or kidney dysfunction, generalized debilitation, prior intensive chemotherapy including autologous or allogeneic HCT, low Karnofsky Performance Status) preclude use of a standard myeloablative conditioning regimen.
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 patient, where usually there is sharing of only three of the six major histocompatibility antigens. Most individuals will have such a donor. The risk of morbidity (e.g., graft-versus-host disease [GVHD]) may be higher than with HLA matched donors; however, as medical treatments improve, the risks of GVHD with haploidentical donors are approaching those similar to HLA-matched donors.
Note: The use of killer cells in the treatment of malignancies is addressed separately Medical Policy #105: Adoptive Immunotherapy.
DESCRIPTION OF PROCEDURE OR SERVICE:
Acute Lymphoblastic Leukemia
Acute Lymphoblastic Leukemia is a heterogeneous disease with different genetic alterations resulting in distinct biologic subtypes. Patients are stratified by certain clinical and genetic risk factors that predict an outcome, with risk-adapted therapy tailoring treatment based on the predicted risk of relapse. Two of the most important factors predictive of risk are patient age and white blood cell count at diagnosis. Certain genetic characteristics of leukemic cells strongly influence prognosis.
Childhood Acute Lymphoblastic Leukemia
Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in children and represents nearly 25% of cancer diagnoses in children younger than 15 years. Complete remission (CR) of disease is now typically achieved with pediatric chemotherapy regimens in approximately 98% of children with ALL, with long-term survival rates of up to 85%. Survival rates have improved with the identification of effective drugs and combination chemotherapy through large randomized trials, integration of presymptomatic central nervous system prophylaxis, and intensification and risk-based stratification of treatment. The prognosis after first relapse is related to the length of the original remission. For example, leukemia-free survival is 40% to 50% for children whose first remission was longer than 3 years, compared with only 10% to 15% for those who relapse less than 3 years following treatment. Thus, HCT may be a strong consideration in those with short remissions. At present, comparative outcomes with either autologous or allo-HCT are unknown.
Adult Acute Lymphoblastic Leukemia
In adults, ALL accounts for 20% of acute leukemias. Between 60% and 80% of adults with ALL can be expected to achieve complete remission after induction chemotherapy; however, patients who experience a relapse after remission usually die within 1 year. Differences in the frequency of genetic abnormalities that characterize adult ALL versus childhood ALL help, in part, explain the outcome differences between the two groups. For example, the “good prognosis” genetic abnormalities such as hyperdiploidy and translocation (t) of chromosomes 12 and 21, are seen much less commonly in adult ALL, whereas they are some of the most common in childhood ALL. Conversely, “poor prognosis” genetic abnormalities such as the Philadelphia chromosome (translocation of chromosomes 9 and 22) are seen in 25% to 30% of adult ALL but infrequently in childhood ALL. Other adverse prognostic factors in adult ALL include age greater than 35 years, poor performance status, male sex, and leukocytosis at presentation of greater than 30,000/μL (B-cell lineage) or greater than 100,000/μL (T-cell lineage).
Hematopoietic Cell Transplantation
Hematopoietic cell transplantation is a procedure in which hematopoietic stem cells are intravenously infused to repair bone marrow and immune function in cancer patients who receive bone marrow-toxic doses of cytotoxic drugs with or without whole-body irradiation. Hematopoietic stem cells may be obtained from the transplant recipient (autologous HCT) or a donor (allo-HCT). They can be harvested from bone marrow, peripheral blood, or umbilical cord blood shortly after delivery of neonates. The use of cord blood is discussed in Medical Policy #439: Placental/Umbilical Cord Blood as a Source of Stem Cells.
Immunologic compatibility between infused hematopoietic stem cells and the recipient is not an issue in autologous HCT. In allogeneic stem cell transplantation, immunologic compatibility between donor and patient is a critical factor for achieving a successful outcome. Compatibility is established by typing of human leukocyte antigens (HLA) 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.
Conditioning for Hematopoietic Cell Transplantation
Conventional Conditioning
The conventional (“classical”) practice of allo-HCT involves administration of cytotoxic agents (e.g., cyclophosphamide, busulfan) with or without existing disease in the absence of pretransplant conditioning. Intense conditioning regimens are limited to patients whose health status is sufficient to tolerate the procedure of 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 the initial eradication of malignant cells and subsequent graft-versus-malignancy effect mediated by non-self-immunologic effector cells. While the slower graft-versus-malignancy effect is considered the potentially curative component, it may be overwhelmed by substantial adverse effects. These include opportunistic infections secondary to loss of endogenous bone marrow function and organ damage or failure caused by cytotoxic drugs. After 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 re-population of the bone marrow with presumably normal 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. Individuals who undergo autologous HCT are also 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 or less intense regimens of cytotoxic drugs or radiation than are used in conventional full-dose myeloablative conditioning treatments. Although the definition of RIC remains arbitrary, with numerous versions employed, all seek to balance the competing effects of NRM and relapse due to residual disease. The goal of RIC is to reduce disease burden but also to minimize as much as possible associated treatment-related morbidity and non-relapse mortality (NRM) in the period during which the beneficial GVM effect of allogeneic transplantation develops. These RIC regimens can be viewed as a continuum in effects, from nearly totally myeloablative, to minimally myeloablative with lymphoablation, with intensity tailored to specific diseases and patient condition. Individuals who undergo RIC with allogeneic HCT initially demonstrate donor cell engraftment and bone marrow mixed chimerism. Most will subsequently convert to full-donor chimerism, which may be supplemented with donor lymphocyte infusions to eradicate residual malignant cells. For the purposes of this policy, the term “reduced-intensity conditioning” will refer to all conditioning regimens intended to be non-myeloablative.

Summary of Evidence
For individuals who have childhood ALL in first complete remission (CR1) at high-risk of relapse, remission, or refractory ALL who receive autologous HCT, the evidence includes RCTs and systematic reviews. Relevant outcomes are overall survival (OS), disease-specific survival (DSS), and treatment-related mortality (TRM) and morbidity. For children with high-risk ALL in CR1 or with relapsed ALL, studies have suggested that HCT is associated with fewer relapses but higher death rates due to treatment-related toxicity. However, for a subset of high-risk patients in second complete remission or beyond or with relapsed disease, autologous HCT is a treatment option. This conclusion is further supported by an evidence-based systematic review and position statement from the American Society for Blood and Marrow Transplantation (ASBMT). The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.

For individuals who have adult ALL in CR1, subsequent remission, or refractory ALL who receive autologous HCT, the evidence includes RCTs and systematic reviews. Relevant outcomes are OS, DSS, and TRM and morbidity. Current evidence supports the use of autologous HCT for adults with high-risk ALL in CR1, whose health status is sufficient to tolerate the procedure. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals who have adult ALL in CR1 or subsequent remission or refractory ALL who receive allo-HCT, the evidence includes RCTs, systematic reviews, and observational studies. Relevant outcomes are OS, DSS, and TRM and morbidity. Current evidence supports the use of myeloablative allo-HCT for adults with any risk level ALL, whose health status is sufficient to tolerate the procedure. Reduced-intensity conditioning allo-HCT may be considered for patients who demonstrate complete marrow and extramedullary first or second remission and who could be expected to benefit from a myeloablative allo-HCT, but for medical reasons would not tolerate a myeloablative conditioning regimen. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals who have relapsed after a prior autologous HCT for ALL adult or childhood who receive allo-HCT, the evidence includes case series. Relevant outcomes are OS, DSS, and TRM and morbidity. Evidence reviews have identified only small case series with short-term follow-up, which was considered inadequate evidence of benefit. However, clinical input has been obtained from specialty societies and academic medical centers which had a general agreement that allogeneic hematopoietic cell transplantation is considered medically necessary to treat relapsed acute lymphoblastic leukemia (ALL) after a prior autologous HCT in either children or adults.
Practice Guidelines and Position Statements
National Comprehensive Cancer Network
Current National Comprehensive Cancer Network guidelines (v.3.2023) for ALL indicate allo-HCT is appropriate for consolidation treatment of most poor risk (e.g., the Philadelphia chromosome positive, relapsed, or refractory) patients with ALL. The guidelines state that for appropriately fit older adults with ALL who are achieving remission, “consideration of autologous or reduced-intensity allogeneic stem cell transplantation may be appropriate.” In addition, the guidelines note that chronologic age is not a good surrogate for fitness for therapy and that patient should be evaluated on an individual basis.
Current National Comprehensive Cancer Network guidelines (v.3.2024) for pediatric ALL say that "Allogeneic HCT has demonstrated improved clinical outcomes in pediatric ALL patients with evidence of certain high-risk features and/or persistent disease. In addition, survival rates appear to be comparable regardless of the stem cell source (matched related, matched unrelated, cord blood, or haploidentical donor)." The guidelines state that the benefit of allo-HCT in infants is still controversial.
The American Society for Transplantation and Cellular Therapy
In 2020, the guidelines from The American Society for Transplantation and Cellular Therapy (previously known as the American Society for Blood and Marrow Transplantation) were published on indications for autologous and allo-HCT. Recommendations were intended to describe the current consensus on the use of HCT in and out of the clinical trial setting. Recommendations on ALL are listed in Table 1.

All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.
This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.
The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.
As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.
The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:
1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.
Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:
1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
