case 1
Case #1

A young woman with leukemia needs bone marrow, and her 16-year-old brother is a perfect match. He’s thrilled about “saving” her life.

The problem: he’s mentally disabled and has the cognitive abilities of an 8-year-old.

Should he be allowed to donate?

Pentz et al. Oncologist. 2008.

case 2
Case #2

A 9 year old has aplastic anemia. She has two brothers. Both are tested and both are histocompatible. One brother was tolerant of testing, the other was anxious and distraught.

Should minors be permitted to donate?

How to choose when two are histocompatible?

ethical issues for donors
Ethical issues for donors



Health problems

Mental health problems


Most donors report that they feel unable to refuse

One third say they felt coerced by parents or a doctor

The other two thirds said their consciences wouldn’t allow them to decline

MacLeod et al. J Pediatr Psychol. 2003.


Sick children and their donor siblings have different, possibly even conflicting, needs

Parents and care-providers are focused on the sick child

Most programs do not have separate doctors or services for the donor

Opel et al. J Clin Ethics. 2006.

feelings good and bad
Feelings good and bad

Donors in successful transplants reported feeling better about themselves and closer to their families as a result

Donors whose siblings died post-transplant had more anger, guilt and self-blame

MacLeod et al. J Pediatr Psychol. 2003.

A happier, more functional family

donor siblings need care
Donor siblings need care

“Siblings should not be neglected at any stage of the BMT process. They should be seen as an integral part of the family system, and acknowledged as important participants in the treatment process.” *

“The oncology community may want to enhance its support of donor and non-donor siblings to help avoid the negative sequelae experienced by some.” **

* Packman et al. J Dev Behav Pediatr. 1997.

**Pentz. Oncologist.2008.

donor advocates
Donor advocates

The M.D. Anderson Cancer Center appoints a medical and psychological team that “focuses solely on the welfare of the donor, whereas the cancer patient’s team focuses solely on the patient. Conflicts of interest inherent in one medical team caring for both the patient and the donor are avoided and, presumably, more attention can be paid to the donor’s needs.”

Few other centers have such programs.

legal cases
Legal cases
  • Most legal cases involve kidney transplants:
    • Strunk v. Strunk (Ky.1969), 445 S.W.2d 145
    • Hart v. Brown, (Conn. 1972)289 A.2d 386
  • One of the few bone marrow transplant cases that went to court was unusual in that the proposed donors were half-siblings who had no relationship with the recipient
    • In Curran v. Bosze, the Illinois Supreme Court ruled that 3 ½-year-old twins did not have to be tested for HLA compatibility with a 12-year-old half-brother with acute undifferentiated leukemia. The three children shared the same father but were born to different mothers. The twins barely knew their half-brother. The twins’ mother was adamant that they not be subjected to bone-marrow extraction, and the 12-year-old had at best a tiny chance of surviving even with marrow from one of the twins.
    • For the actual court decision in Curran v. Bosze:
Other questions:

Do things change if the sick child needs more than one transplant?

Do things change if the donor is brought into existence to be a donor?

Is IVF/PGD acceptable to select a compatible child?

Can you “prep” the donor G-CSF?

aap policy statement
AAP policy statement

Minor sibling donation of marrow, peripheral or cord blood is morally acceptable, provided the following five standards are met:

1- No histocompatible adult is available. (However, sibling donation may be pursued before a broader search has been completed.)

2- The potential donor and sick siblings should have a close and positive relationship.

AAP Committee on Bioethics. Pediatrics. 2010.

AAP statement (cont’d)

3- There should be a good likelihood the recipient will survive, especially since a failed transplant can cause donor to feel responsible.

4- Psychosocial risks to the donor should be minimized through medical play-acting, answering the potential donor’s questions and giving him/her a role in making a decision.

Also, the treatment team should help parents identify and attend to needs of donor.

AAP Committee on Bioethics. Pediatrics. 2010.

aap statement cont d1
AAP statement – (cont’d)

5- An advocate should be appointed to represent the potential donor.

Every effort should be made to obtain the potential donor’s assent including, if needed, a consultation with a hospital ethics committee.

The potential donor should be thoroughly informed about the procedure, the possible results, and the limits to his/her role in the outcome.

AAP Committee on Bioethics. Pediatrics. 2010.
