DESCRIPTION
High-dose (myeloablative) chemotherapy involves the administration of cytotoxic agents at doses several times greater than the standard therapeutic dose. In some cases, whole body or localized radiotherapy is also given. The rationale for high-dose chemotherapy (HDC) is the belief that many cytotoxic agents act according to a steep dose-response curve. Thus, small increases in the dosage will result in relatively large increases in tumor cell kill. However, increasing the dose also increases the incidence and severity of adverse effects (e.g., opportunistic infections, hemorrhage, and organ failure). Since the probability of life-threatening toxicity is so high, individuals are usually hospitalized for an extended period in order to undergo HDC. They also require hospitalization beyond the period of drug administration. HDC typically requires treatment with one or more support measures specifically developed to combat adverse effects.
The standard follow-up to treatment with HDC includes the transplantation of bone marrow, peripheral stem cells or cord blood. This is a technique involving the collection of donor marrow or stem cells and preparation for infusion to rescue hematopoiesis in a recipient previously treated with a cytoreductive regimen. Treatment for certain cancers has also included infusion of allogeneic bone marrow or stem cells. However, unlike treatment of primary marrow diseases in which allogeneic bone marrow infusion is the treatment, bone marrow / stem cell infusion in the treatment of cancers is used solely to support high-dose chemotherapy.
Hematopoietic stem cells are those cells found within the bone marrow. These cells facilitate continuous blood cell production. In certain malignant or nonmalignant disease processes, these necessary building cells are damaged or destroyed. Infusion of transplanted hematopoietic stem cells is done to restore normal hematopoiesis or immune function.
There are several methods used to obtain stem cells for transplant. Autologous bone marrow transplantation refers to harvesting of bone marrow, usually from the iliac crest, or from the peripheral blood using a pheresis procedure. The harvested cells are then re-administered to the same individual. Allogeneic bone marrow transplantation involves harvesting of hematopoietic stem cells from a healthy donor (related or unrelated) for infusion into an individual whose bone marrow is compromised. This procedure can be used as a treatment for certain congenital, hereditary or acquired disease defects / processes or as an intentional or unintentional consequence of the treatment of medical conditions. There are three potential sources for obtaining allogeneic stem cells: bone marrow, peripheral blood and placental or umbilical cord blood. The use of allogeneic peripheral stem cells and bone marrow is viewed as essentially equivalent for malignant disease and myeloplastic syndromes. Direct bone marrow may be the only appropriate treatment for some nonmalignant diseases.
Immunologic compatibility between donor and individual is a critical factor for achieving a good outcome with allogeneic bone marrow transplantation due to the risks of graft rejection and graft-versus-host disease. Serologic typing of tissue of human leukocyte antigens (HLA) and mixed leukocyte cultures are used to determine compatibility. HLA antigens refer to the tissue type expressed at the HLA A, B and DR loci on each leg of chromosome 6. Depending upon the age of the recipient and the specific disease being treated, an acceptable donor may be required to have a perfect match of all six loci, or may be allowed to have one, two or rarely three mismatches. In all cases, donor and recipient tissue must be non-reactive in mixed leukocyte culture or molecular DNA typing.
POLICY
High dose chemotherapy followed by bone marrow / stem cell transplantation for the treatment of certain disease processes is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
High dose chemotherapy and/or other marrow ablative treatments followed by hematopoietic stem cell transplantation are considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
High dose chemotherapy followed by transplantation with umbilical cord or placental blood stem cells from unrelated or related donors with an appropriate indication for allogeneic stem cell transplant, but without a hematopoietic stem cell donor is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
Collection and storage of cord blood from a neonate when an allogeneic transplant is imminent in an identified recipient with a diagnosis that is consistent with the possible need for allogeneic transplant is considered medically necessary.
Repeated labs and procedures to address changes in condition and for continued transplant listing are considered medically necessary.
High dose chemotherapy followed by stem cell / bone marrow transplantation for the treatment of all stages of breast cancer is considered investigational. This applies to all contracts.
Prophylactic collection and storage of cord blood from a neonate when proposed for some unspecified future use as an autologous stem-cell transplant in the original donor or for some unspecified future use as an allogeneic stem-cell transplant in a related or unrelated donor is considered not medically necessary.
Multiple labs and work-up procedures for the sole purpose of repeat evaluation at multiple transplant centers are considered not medically necessary.
Any chemotherapeutic agent utilized for this procedure
must have FDA approval specific to the indication or for some off-label
indication, otherwise it will be considered
investigational.
Note: off-label indication must be supported by published, clinical
data that supports its efficacy; and regimens utilized must be standardized
by the institution, and the protocol approved by the institution's Internal
Review Board (IRB).
