    Abstract:
    Chronic myelogenous leukemia (CML) is a malignant disease of hematopoietic stem cell with a biphasic or triphasic clinical course and most often, with a fatal outcome. Significant progress in improving outcome for patients with CML has been achieved over past years. This can be attributed to marked improvement in therapeutic protocols and increased use of bone marrow transplantation (BMT) which remains the most effective option for long-term disease control of patient with CML. The residual leukemic activity in patients after BMT remains a central clinical question. To effectively monitor minimal residual disease leukemic activity after BMT, molecular genetic techniques are currently utilized in conjunction with cytogenetic assays. Because the clinical significance of detection minimal residual disease in CML remains to be determined, we performed cytogenetic analysis and PCR amplification technique in 37 Ph+ CML patients. All patients received transplants for CML in Bratislava between years 1992 and 1999. Our results suggest that PCR positivity after transplant is of limited prognostic significance for particular individuals and can be used to identified groups of individuals at elevated risk of relapse.
