Not all patients are suitable candidates for a transplant. Factors that influence candidacy include: - Overall Health: Patients must be in relatively good health to endure the procedure and recovery. - Age: Younger patients tend to have better outcomes, although age alone is not a determining factor. - Disease Status: The stage and type of cancer, as well as how it responds to other treatments, play a role in deciding transplant suitability. - Availability of a Suitable Donor: For allogeneic transplants, finding a matching donor is critical.
