ABSTRACT

The paper raises a problem of preparing samples in hematology. It considers whether the preanalytical stage is of importance in hematological studies. The use of disposal vacuum blood collection systems is shown to solve the problem in the standardization of a blood sampling procedure. The benefits of the use of close tube hematology analyzers are also considered.

ABSTRACT

AIM: To analyse clinical implications of chromosome 8 trisomy in Ph-negative cells of the bone marrow in patients with chronic myeloid leukemia (CML) treated with inhibitors of tyrosinkinases (ITK). MATERIAL AND METHODS: A total of 386 patients with CML (chronic phase--288, acceleration phase--77) received imatinib (400-800 mg/day). Because of resistance and/or intolerance some patients were switched to ITK II (nilotinib, dasatinib, bozutinib). This study included 8 CML patients (7 in a chronic phase, 1 in acceleration phase) treated with BCR-ABL ITK inhibitors of the first (imatinib) and the second line (ITK-II). The standard cytogenetic examination, on demand--investigation of the interphase nuclei with FISH, in some cases morphological, cytochemical and histological examinations of the bone marrow were made. RESULTS: The existence of a Ph-negative clone with trisomy of chromosome 8 had no negative effect on the course of the disease. The patients showed a stable hematological and cytogenetic response and no need in changing treatment policy. In long-term follow-up Ph-negative clone with trisomy of the chromosome 8 persisted without a clear trend to rise in most patients. CONCLUSION: Detection of a Ph-negative clone with chromosome 8 trisomy at early stages suggests parallel existence of Ph-positive and Ph-negative clones. None of the patients had myelodisplasia.

ABSTRACT

AIM: To characterize clinical symptoms, course, immediate and long-term treatment results in young patients with hair cell leukemia (HCL). MATERIAL AND METHODS: The data on 41 HCL patients were analysed. The diagnosis was made by standard diagnostic protocol for HCL detection. RESULTS: The analysis of the age of 160 HCL patients studied demonstrated high (26%) incidence of HCL at young age. Young patients with HCL had special clinical manifestations and specific long-term outcomes of treatment with standard schemes. CONCLUSION: Differences in occurrence of recurrences after standard therapy make it necessary to consider young HCL patients as a separate group who need adjuvant treatment to prolong remission.
