A 60-year-old male patient presented with jaundice. Initial investigations showed anemia, indirect hyperbilirubinemia, raised Lactic Dehydrogenase (LDH) and increased reticulocyte count suggestive of hemolysis. Considering hemolysis low MCV and basophilic stippling on peripheral film, hemoglobin electrophoresis was done that showed Haemoglobin H (15.5%) that in the absence of family history was...
A 60-year-old woman with squamous cell carcinoma in the right lung was successfully treated with four cycles of combination chemotherapy after surgery, and complete remission was achieved. However, the patient developed myelodysplastic syndrome (MDS) RAEB-2 with myelofibrosis after remission, possibly because of chemotherapy or DNA methylation. The patient responded well to dacitabine (Dacogen)...
مقدمه و هدف :سندرم میلودیسپلاستیک (mds)، ناهنجاری هماتوپویتیک است که به وسیله تغییرات دیسپلاستیک سلول های پیش ساز خونی مشخص و منجر به خونسازی غیر موثر در مغز استخوان و سیتوپنی در خون محیطی می شود. امروزه در دامپزشکی تشخیص و طبقه بندی نئوپلاسم های خون در سگ و گربه بر اساس طبق بندی fab توسعه یافته است. ناهنجاری خونی مربوط به دیسپلازی سلول های خون مجموعا به عنوان سندرم میلودیسپلاستیک در سیستم fab ...
Myelodysplastic syndrome (MDS) is a hematopoietic stem-cell disorder characterized by trilineage dysplasia and susceptibility to acute myelogenous leukemia (AML). Analysis of molecular basis of MDS has been hampered by the heterogeneity of the disease. Recently, mutations of the transcription factor AML1/RUNX1 have been identified in 15% to 40% of MDS-refractory anemia with excess of blasts (RA...
We evaluated the impact of World Health Organization (WHO) classification and WHO classification-based Prognostic Scoring System (WPSS) on the outcome of patients with myelodysplastic syndrome (MDS) who underwent allogeneic stem cell transplantation (allo-SCT) between 1990 and 2006. Five-year overall survival (OS) was 80% in refractory anemias, 57% in refractory cytopenias, 51% in refractory an...
The breakpoint on chromosome 20 is not constant; 20qis frequently associated with other cytogenetic abnormalities as del(5q), trisomy 8, trisomy 21, deletions or translocations involving the long arm of chromosome 13; a newly described translocation t(11;20)(p15;q11) resulting in a NUP98TOP1 fusion gene was described in therapy-related myelodysplastic syndrome (RAEB); t(11;20)(p15;q11) is a rar...
Myelodysplastic syndromes (MDSs) are clonal hematologic disorders that frequently represent an intermediate disease stage before progression to acute myeloid leukemia (AML). As such, study of MDS/AML can provide insight into the mechanisms of neoplastic evolution. In 184 patients with MDS and AML, DNA methylation microarray and high-density single nucleotide polymorphism array (SNP-A) karyotypi...
Somatic mutation of the N-ras oncogene occurs frequently in de novo acute myeloid leukemia (AML). By virtue of their relation to AML, myelodysplastic syndromes (MDS) provide an in vivo model of human leukemogenesis. By using a strategy for analysis of gene mutation based on in vitro amplification of target sequences by the polymerase chain reaction (PCR) and selective oligonucleotide hybridizat...
