Abstract
The aim of the present study was to detect the frequency of monosomy 7 and trisomy 8 in myeloid disorders acute myeloblastic leukemia AML myelodysplastic syndrome MDS their association with GSTT1 and GSTM1 null genotypes and their prognostic impact The study included 50 patients with AML and MDS monosomy 7 and trisomy 8 detection was done by interphase fluorescence in situ hybridization and glutathione Stransferase GST genotyping was done by multiplex PCR Monosomy 7 was present in 13–30 of AML and MDS respectively A statistically significant relation was found between monosomy 7 and remission failure Trisomy 8 was found in 10–15 of AML and MDS No significant association was found between response to treatment and trisomy 8 There was significant correlation between GSTT1 null/GSTM1 null genotype and poor response to treatment p 0005 There was positive correlation between complete remission and both wild GST genotypes In the whole patient group a statistically significant association was found between GSTT null genotypes and monosomy 7 p = 0003 No significant association was found between trisomy 8 and specific GST genotypic polymorphism
