Methods and compositions for the monitoring and quantitation of minimal residual disease in hematopoietic tumors

摘要

Methods and compositions for monitoring the presence of minimal residual hematopoietic tumor cells, such as T-cell acute lymphoblastic leukemia cells, in remission cells of a patient. The invention relates to using nucleic acid hybridization probes to detect alteration of tal-1 locus on chromosome 1 from a DNA extract to confirm the presence of residual T-cell acute lymphoblastic leukemia cells in the patient. Methods to quantitate the amount of hematopoietic cells are described. Kits for detecting and monitoring hematopoietic tumor cells in a patient are provided. Kits for quantitating hematopoietic tumor cells in a patient in remission are also provided.
