• Status: Completed
• Trial end date: 2006-02-01

Summary

RATIONALE: Umbilical cord blood transplantation may allow doctors to give higher doses of chemotherapy or radiation therapy and kill more cancer cells.

PURPOSE: This phase II trial is studying how well umbilical cord blood transplantation works in treating patients with severe aplastic anemia, malignant thymoma, or myelodysplasia.
