Exercise during allogeneic stem-cell transplantation

Evidence label: Small randomized supportive signal · Clinical goal: preserve endurance, strength and quality of life during allogeneic transplantation

Evidence at a glance

Population: 47 adults undergoing allogeneic hematopoietic stem-cell transplantation.
Intervention: endurance and daily-living activity twice daily during the inpatient transplant phase.
Result: endurance, strength, fatigue and emotional-state measures favored exercise over standard once-daily physiotherapy.

What was studied

The randomized trial began exercise alongside conditioning chemotherapy and total-body irradiation. The comparison group received the center’s standard physiotherapy once daily.

What the evidence shows

Differences or favorable trends were reported for endurance (P=.002), strength (P=.022), fatigue (P=.046) and emotional state (P=.028), without additional reported individual risk. The study did not establish effects on graft complications, relapse or survival.

This is supportive-care or rehabilitation evidence. It does not show that the intervention treats cancer, prevents recurrence or prolongs survival unless a record explicitly identifies a validated cancer-control endpoint.

Limits and uncertainty

The trial was small and single-setting, used an active control and reported P values without the absolute effect estimates needed to judge clinical importance. Reviews find heterogeneous programs and outcomes. A separate survival analysis was not designed or stratified to prove survival benefit.

Safety and practical context

Transplant exercise must change with fever, infection, anemia, thrombocytopenia, graft-versus-host disease, lines, falls and isolation requirements. The transplant and rehabilitation teams should set daily limits.

Questions for the care team

What blood-count or infection thresholds change today’s plan?
Which exercises are safe with my central line and fall risk?
Are we measuring endurance, fatigue and function rather than assuming a survival effect?
