Physical activity for patients undergoing an allogeneic hematopoietic stem cell transplantation: benefits of a moderate exercise intervention.

UNLABELLED: An allogeneic hematopoietic stem cell transplantation (HSCT) can have profound and lasting adverse effects on a patient's physical and psychological well-being. So far, only few studies have investigated the effectiveness of physical activity over the entire inpatient phase of an allogeneic HSCT. PURPOSE: We performed a randomized controlled study to examine the influence of a controlled moderate exercise program starting parallel to chemotherapeutic conditioning and total body irradiation on the patient's physical and psychological constitution. PATIENTS AND METHODS: Forty-seven patients undergoing an allogeneic HSCT were randomly assigned to an exercise group (EG) or a control group (CG). While the EG took part in an endurance and activity of daily living-training twice a day, the CG received the clinic's standard physiotherapy program once a day. RESULTS: Significant differences and/or trends in favor of the EG were observed regarding the primary endpoint endurance performance (P=0.002), muscular strength (P=0.022), fatigue (P=0.046), and emotional state (P=0.028) without posing an additional risk for the individual. CONCLUSION: The results show that the training program is feasible and seems to have positive influences on physical performance and quality of life in patients undergoing an allogeneic HSCT. However, further studies are necessary to confirm these results.

Outcome of allogeneic hematopoietic stem-cell transplantation in adult patients with acute lymphoblastic leukemia: no difference in related compared with unrelated transplant in first complete remission.

PURPOSE: The role of unrelated allogeneic stem-cell transplantation in acute lymphoblastic leukemia (ALL) patients is still not clear, and only limited data are available from the literature. We analyzed factors affecting clinical outcome of ALL patients receiving a related or unrelated stem-cell graft from matched donors. PATIENTS AND METHODS: The total study population was 264 adult patients receiving a myeloablative allogeneic stem-cell transplant for ALL at nine bone marrow transplantation centers between 1990 and 2002. Of these, 221 patients receiving a matched related or unrelated graft were analyzed. One hundred forty-eight patients received transplantation in complete remission; 62 patients were in relapse; and 11 patients were refractory to chemotherapy before transplant. Fifty percent of patients received bone marrow, and 50% received peripheral blood stem cell from a human leukocyte antigen-identical related (n = 103), or matched unrelated (n = 118) donor. RESULTS: Disease-free survival (DFS) at 5 years was 28%, with 76 patients (34%) still alive (2.2 to 103 months post-transplantation), and 145 deceased (65 relapses, transplant-related mortality, 45%). We observed an advantage regarding DFS in favor of patients receiving transplantation during their first complete remission (CR) in comparison with patients receiving transplantation in or after second CR (P =.014) or who relapsed (P <.001). We observed a clear trend toward improved survival in favor of B-lineage ALL patients compared with T-lineage ALL patients (P =.052), and Philadelphia chromosome-positive patients had no poorer outcome than Philadelphia chromosome-negative patients. Total-body irradiation-based conditioning improved DFS in comparison with busulfan (P =.041). CONCLUSION: Myeloablative matched related or matched unrelated allogeneic hematopoietic stem-cell transplantation in ALL patients should be performed in first CR.
