DESCRIPTION
Hematopoietic stem cell transplantation (HSCT) refers to a procedure in which hematopoietic stem cells are infused to restore bone marrow function in individuals who receive bone marrow-toxic doses of cytotoxic drugs with or without whole body radiotherapy. Hematopoietic stem cells can be harvested from bone marrow, peripheral blood or from umbilical cord blood shortly after delivery of neonates.
Autologous HSCT typically occurs after induction chemotherapy once complete remission has been achieved. The individual’s stem cells are mobilized from the bone marrow to the peripheral bloodstream and harvested. High dose chemotherapy is administered to eradicate any lingering cancer cells followed by reinfusion of the stem cells.
Allogeneic HSCT involves stem cells collected from a donor who is selected based on the results of human leukocyte antigen (HLA) typing. A close HLA match increases the likelihood of a successful transplant. Prior to the transplant, the recipient undergoes intensive treatment to destroy cancerous cells. The donor cells are infused into the bloodstream and travel to the bone marrow where they begin to produce new cells in a process known as engraftment.
HSCT is an established treatment for certain hematologic malignancies; however, its use in solid tumors in adults continues to be largely experimental.
POLICY

Breast cancer
Cancer of the bile duct
Cancer of the fallopian tubes
Cervical cancer
Colon cancer
Esophageal cancer
Gallbladder cancer
Lung cancer, any histology
Malignant melanoma
Nasopharyngeal cancer
Neuroendocrine tumors
Paranasal sinus cancer
Pancreatic cancer
Prostate cancer
Rectal cancer
Renal cell cancer
Soft tissue sarcomas
Stomach cancer
Thyroid tumors
Tumors of the thymus
Tumors of unknown primary origin
Uterine cancer
For Neuroblastoma, please refer to the MCG Care Guideline - Medical Oncology GRG.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed.

ADDITIONAL INFORMATION
Peer reviewed studies on the use of autologous or allogeneic stem cell transplantation in the treatment of solid tumors in adults are limited. There is insufficient evidence to permit conclusions regarding improved health outcomes.
