Bone Marrow Transplantation; A Success Story
Editorial in Middle East Health Magazine, Dec. 2006 by James O. Armitage, MD/University of Nebraska Medical Center, Omaha, NE, USA
It is very popular today to speak of stem cell research and the use of stem cells to treat disease. However, many involved in the debate regarding research and clinical applications of stem cells might not appreciate that hematopoietic stem cells have been used therapeutically for half a decade. Attempts to use hematopoietic stem cells to replace marrow aplastic anemia or to support intensive therapy of cancer began even more than 50 years ago. However, it was not until more was understood about bone marrow functions and the nature of the hematopoietic stem cell before the procedure that we know today as hematopoietic stem cell transplantation became practical. In the 1960’s successful allogeneic (i.e. from one individual to another) hematopoietic stem cell transplantation was reported for the treatment of leukemia and for the treatment of inherited immune defects. Working at the University of Washington in Seattle Dr. Don Thomas (i.e. who won the Nobel Prize) and his colleagues worked out the techniques of hematopoietic stem cell transplantation to treat leukemia and aplastic anemia. By the mid 1970s they reported 100 patients with acute leukemia treated with this approach with some patients surviving free of disease and apparently cured.
The presumed benefit of allogeneic hematopoietic stem cell transplantation was originally thought to be a consequence of the very intensive therapy administered before the infusion of hematopoietic stem cells. It was known that unless a severely immunosuppressive treatment was applied, the patients own immune system would destroy the new hematopoietic stem cells. Thus, high dose therapy was administered before the transplant in an attempt to allow engraftment and to eradicate the malignancy—i.e. usually leukemia. Proof that immunosuppression was also required came from attempts to do hematopoietic stem cell transplantation in aplastic anemia. It was originally felt that simply infusing hematopoietic stem cells should cure this disease since the marrow was “empty”. However, it became apparent that in the absence of destruction of the patient’s residual immune cells, the new hematopoietic stem cells would be destroyed. Thus, in patients with cancer, the very intensive therapy administered before infusion of the new hematopoietic stem cells was felt to be both curative of the cancer and engraftment.
In the late 1970’s and early 1980’s, it became apparent that the new hematopoietic stem cells and the new immune system that they produced in the patient might also have an anticancer effect. The main complication of allogeneic hematopoietic stem cell transplantation is the development of a condition known as graft versus host disease. In this illness, the new immune system produced by the infused, allogeneic hematopoietic stem cells can recognize the patient as “foreign” and carry out an immune attack on the patient’s organs. Injury in this condition is especially frequently seen in the skin, liver, and gastrointestinal tract, and can some times be fatal. In the late 1970s and early 1980s remission of relapsed leukemia was noted in patients who developed severe graft versus host disease. It was speculated that there might be a graft versus leukemia effect and that it could be therapeutically important. Careful studies of large numbers of patients demonstrated that patients who developed graft versus host, were less likely to have recurrent leukemia. In fact, it appeared that much of the curative effect of allogeneic hematopoietic stem cell transplantation might be from the anticancer effect of the new immune system.
This observation led to attempts at reducing the intensity of the pretransplant therapy to reduce some of the risks of the procedure. It is possible to use predominantly drugs that impair lymphocyte function with relatively minor toxic effects in the patient and avoid very high doses of other chemotherapeutic agents or total body radiotherapy. It became apparent that sufficient impairment of the patient’s lymphocytes could allow the new hematopoietic stem cell graft to grow and eventually destroy the residual host lymphocytes giving a complete graft. In some cancers that seem to be particularly sensitive to immunological attack, e.g. chronic myeloid leukemia and chronic lymphoid leukemia, the graft versus leukemia effect seems to be potentially curative and the reduced intensity treatment before the transplant appears to reduce transplant related mortality. In those patients in whom the cancer does recur, reinfusing more of the donor’s lymphocytes often will reestablish remission. This approach is sometimes termed reduced intensity allogeneic hematopoietic stem cell transplantation, or mini transplant is now undergoing intensive study in transplant centers throughout the world.
The idea that very high doses of anticancer therapy might be curative for some patients with cancer, and that the use of reinfusion of the patients own hematopoietic stem cells could avoid the dangers of graft versus host disease, led to clinical trials in what is called autologous hematopoietic stem cell transplantation. In this treatment, hematopoietic stem cells have to be removed from the patient and stored until after the intensive cancer therapy is administered. Since the patient’s own hematopoietic stem cells would be used to reestablish bone marrow function after the treatment, there would be no risk of graft versus host disease. However, early problems with this treatment approach included occasional difficulties in collecting hematopoietic stem cells that were free of contamination by cancer cells and finding a way to store the hematopoietic stem cells for extended periods of time and keep them alive. In allogeneic transplantation, the hematopoietic stem cells are taken from one individual and reinfused quickly into another. However, since it takes time to administer the very intensive therapy, hematopoietic stem cells in autologous transplantation have to be cryopreserved for days to weeks before they are used. Initial attempts at autologous hematopoietic stem cell transplantation involved repetitive bone marrow aspirations from the pelvis and sternum to collect sufficient cells. It was not unusual for 200 aspirates to be required. However, in the mid to late 1980s it became apparent that circulating hematopoietic stem cells could be collected using the process called aphersis where the blood is taken from the body, separated by centrifugation, and the desired cells collected with the rest of the blood reinfused into the patient.
Autologous hematopoietic stem cell transplantation tested the hypothesis that very intensive anticancer therapy could cure some patients when standard therapy failed. Early studies in lymphoma showed that this can, in fact, be the case. In patients whose recurrent or resistant lymphoma still can partially respond to standard doses or chemotherapy and achieve a minimal disease state, hematopoietic stem cell transplantation can often be curative. As is the situation with allogeneic hematopoietic stem cell transplantation, treatment doesn’t benefit patients with all cancers, but is especially effective in patients with lymphoma, certain leukemias, multiple myeloma, and occasional other cancers.
Today both allogeneic and autologous hematopoietic stem cell transplantation are widely utilized to treat patients with cancer. Many patients who would otherwise have died of their malignancy are now cured because of these procedures. Allogeneic hematopoietic stem cell transplantation is also utilized for patients with aplastic anemia, inherited immune deficiency states, and certain other inherited disorders of blood production. Both allogeneic and autologous hematopoietic stem cell transplantation are being studied in the treatment of patients with other life threatening immune diseases. It is likely that both treatments will continue to be an important part of our therapeutic armentarium for years to come.
