When Keegan Doheney was two years old he was diagnosed with leukaemia; a cancer affecting cells in the blood.
Thankfully, doctors were able to get his cancer into remission. While his family remained optimistic about the future they were aware that there was the possibility of a relapse.
When Keegan’s mother Wendy became pregnant again she decided to bank the baby’s cord blood.
Speaking about the decision to bank her son Keldan’s cord blood Wendy said, “Keegan was in great shape, went through all his chemo and came out healthy. So I never thought in my wildest dreams that we would need it.”
When Keegan was in kindergarten, Wendy instinctively knew there was something wrong. “He relapsed with leukaemia when he was five and a half and that turned his odds into a 50% chance of survival”, said Wendy.
The doctors decided that a transplant was the right option to treat Keegan’s leukaemia.
Thankfully, Keldan was a perfect match to donate stem cells to Keegan for the transplant. Because Wendy had decided to store Keldan’s cord blood the stem cells were in storage ready to be used.
Bone marrow stem cells have a 25% chance of being a match between siblings versus cord blood stem cells which have a 50% chance of being a match between siblings.
Additionally, a study found that the one-year survival rate for patients treated with a sibling’s cord blood stem cells is approximately 63%. With cord blood from an unrelated donor, the survival rate drops to 29%.
“I’ve been healthy ever since I was five and a half because of my transplant I got from my little brother and his cord blood. So basically my little brother saved my life”, said Keegan speaking about the transplant. “If it weren’t for him, I wouldn’t be here.”
