Roundtable discussion: Incorporating bone marrow transplantation into NCCN guidelines.

A newly formed National Comprehensive Cancer Network (NCCN) panel on bone marrow transplantation has the task of ensuring the incorporation of allogeneic and autologous transplantation into all disease guidelines where significant evidence exists to warrant their inclusion. The panel is further charged with ensuring that there is consistency among guidelines regarding the use of marrow transplantation. A preliminary review of existing NCCN guidelines found that marrow transplantation was appropriately included for the treatment of the common hematologic malignancies of adults, including acute myeloid leukemia, chronic myeloid leukemia, myelodysplasia, multiple myeloma, Hodgkin's disease, and the malignant lymphomas. Frequent refinements regarding lymphomas will be necessary, particularly in rapidly evolving areas, such as multiple myeloma and myelodysplasia, and conditions with changing definitions, such as malignant disease. The increasing volume of data supporting the use of autologous bone marrow transplantation in advanced primary and responding metastatic breast cancers needs to be reflected in the breast cancer guideline if it is to remain credible. Well-designed and well-conducted clinical trials are the most appropriate setting for all bone marrow transplantations and patient referral to these trials remains the standard of care in all settings.
