A special report: bone marrow transplants using volunteer donors--recommendations and requirements for a standardized practice throughout the world--1994 update. The WMDA Executive Committee.

A primary function of the World Marrow Donor Association is to establish general guidelines covering collaboration between international donor registries and practice in regard to bone marrow transplants (BMTs) in which the donor and recipient reside in different countries. To this end, a special report proposing specific recommendations and requirements was published in 1992. This paper amplifies the previous publication and gives special attention to accreditation of national "hubs" (defined as coordinating centers for each country) and donor, harvest, and transplant centers, details of the marrow harvest procedure, use of peripheral blood (PB) stem cells for allografting, and use of PB lymphoid cells for treatment of leukemia relapsing after BMT.
