简要总结
This trial is looking at using umbilical cord blood from unrelated donors after high dose chemotherapy. It is for people who have cancer of the bone marrow or lymphatic system including leukaemia and lymphoma, or a blood disorder called myelodysplastic syndrome (MDS).
The trial is for babies over 4 weeks old, children, and adults up to the age of 45.
详细描述
During treatment for cancers of the bone marrow or lymphatic system, a lot of the stem cells are damaged and you may need a bone marrow or stem cell transplant to replace them.
Stem cells can also be collected from the umbilical cord of newborn babies. Many people around the world have donated their baby's umbilical cords which are stored safely.
There are usually enough cells in one cord to transplant a small child, but there may not be enough cells for an older child or adult. Researchers want to see if adults and children can safely have stem cells from more than 1 umbilical cord.
Before a transplant, you have high doses of chemotherapy, sometimes with radiotherapy. This intensive conditioning aims to destroy all the cells in your bone marrow, and is called myeloablative conditioning.
The aim of this trial is to see if a transplant using cord blood cells from unrelated donors after myeloablative conditioning is safe, and whether it helps people who need a stem cell transplant but don't have a stem cell donor.

入选标准
- •Subjects must be < 45 years of age and ≥ 28 days old
- •Patients with high risk, advanced or poorly responding haematological disease for which there is published evidence that haematopoietic stem cell transplantation using myeloablative conditioning is likely to be effective
