PURPOSE Most patients with chronic-phase chronic myeloid leukemia (CML) who receive imatinib achieve a complete cytogenetic remission (CCgR) and low levels of BCR-ABL transcripts. CCgR is durable in the majority of patients but relapse occurs in a subset. EXPERIMENTAL DESIGN To determine the potential of quantitative reverse transcription-PCR of BCR-ABL to predict cytogenetic relapse, we seri...
Cytogenetic studies in clonal plasma cell disorders have mainly been done in whole bone marrow or CD138(+) microbead-enriched plasma cells and suggest that recurrent immunoglobulin heavy chain translocations - e.g. t(4;14) -are primary oncogenetic events. The aim of this study was to determine cytogenetic patterns of highly purified aberrant plasma cells (median purity ≥ 98%) in different clona...
BACKGROUND AND PURPOSE Cytogenetic abnormalities, especially chromosome 13 deletion, are high-risk factors for multiple myeloma. Attaining the highest detection rates of cytogenetic abnormalities is important to provide accurate prognostic information to the referring oncologist. The purpose of this study was to use CT-guided percutaneous fine-needle aspiration bone biopsy (CT-guided FNA) of MR...
Iodine-131 (I-131) is often used in thyroid diagnostics and therapy. External and internal exposure to radioiodine can lead to molecular and cellular damage in peripheral blood lymphocytes. The aim of this study was to explore the influence of low and high doses of I-131 on susceptibility to ionizing radiation. Study groups consisted of 30 individuals free of thyroid diseases, 41 patients expos...
Cytogenetic abnormalities at diagnosis are important prognostic indicators in acute myeloid leukemia (AML). AML is categorized into 3 risk groups according to cytogenetic abnormalities; favorable, intermediate, and unfavorable. A new cytogenetic risk group called the monosomal karyotype (MK) had been identified in AML in the unfavorable cytogenetic risk group. The MK was reported to be associat...
BACKGROUND Real time PCR has become the most common technique to monitor BCR-ABL transcript levels of patients treated with kinase inhibitors. The aim of this study was to evaluate BCR-ABL levels of chronic myeloid leukemia patients treated with imatinib in the chronic phase and correlate the response to therapy and event-free survival. METHODS BCR-ABL levels were measured in peripheral blood...
The aims of this study were (1) to evaluate the effect of intermediate (cyclophosphamide alone) or intensive (mitoxantrone, cytosine arabinoside, cyclophosphamide) priming on the cytogenetic response in mobilized bone marrow (BM) or peripheral blood (PB) progenitors in patients with chronic myelogenous leukemia (CML), (2) to determine the incidence of cytogenetic remissions after mobilized prog...
background: occupational and environmental exposures mostly represent mixtures of genotoxic agents, whereas the specificity of biomarker measurements varies widely. exploration of correlations among biomarkers contributes to the further progress of molecular cancer epidemiology and to the selection of the optimal biomarkers for the investigation of human exposure to carcinogens. the aim of this...
Objective(s:Cleft lip/palate are common congenital anomalies, affecting approximately 2/1000 live births. Pierre Robin Sequence is a subgroup of the cleft palate population. Chromosomal abnormalities near the SOX9 gene disrupt the regulation of this gene and prevent the SOX9 protein from properly controlling the development of facial structures, which leads to isolated PRS. The present study wa...
All available data from ongoing studies of second-generation tyrosine kinase inhibitors (TKIs) for treatment of patients with newly diagnosed chronic myeloid leukemia in chronic phase (CML-CP) were reviewed. In two nilotinib phase 2 trials, the speed and depth of molecular and cytogenetic responses were greater than responses to imatinib. Furthermore, only one patient in each study progressed t...
