Abstract Abstract 2778 Poster Board II-754 Introduction: Interstitial deletions involving the long arm of chromosome 5, one of the good prognostic factors, are the most common chromosomal abnormality either as a sole or in combination with other abnormalities in myelodysplastic syndromes (MDS). However, the prognostic impact of del(5q) accompanied by additional chromosome abnormalities remains controversial. We investigated the hematologic, cytogenetic and prognostic features of del(5q) in MDS. Also, we mapped the deleted region on 5q by fluorescence in situ hybridization (FISH), whether the d

Zusammenfassung. Die Deletion des langen Arms des Chromosoms 5, del(5q), ist eine bei Myelodysplastischen Syndromen rekurrent auftretende Veränderung, die diese Erkrankungen nicht nur pathopysiologisch sondern auch hinsichtlich ihrer Therapie von anderen myelodysplastischen Syndromen unterscheidet. Die isoliert auftretende del(5q) ist mit einem günstigen Risikoprofil assoziiert und kann seit der Zulassung von Lenalidomid für diese Entität auch gezielt therapiert werden.

Abstract Purpose. The positive lenalidomide experience in lower risk myelodysplastic syndrome (MDS) with deletion 5q and red blood cells transfusion dependence resulted in its broad use in MDS. The study aim was to define the prognosis in MDS and deletion 5q with or without other cytogenetic abnormalities. Patients and Methods. Patients with MDS (<20% blasts) and evaluable cytogenetic studies (1966-present) were reviewed. Outcome of patients with deletion 5q or with loss of chromosome 5 (monosomy 5) was evaluated by the presence or absence of additional chromosomal abnormalities, overal

Abstract:
Whereas lenalidomide is an effective therapy for del(5q) MDS patients, a minority of non-del(5q) MDS patients achieve hematologic improvement with lenalidomide. We used computational biology modeling and digital drug simulation to examine genomic data from 56 non-del(5q) MDS patients treated with lenalidomide, and then matched treatment response with molecular pathways. The computer inferred genomic abnormalities associating with lenalidomide treatment response in non-del(5q) MDS to include trisomy 8, del(20q), or RUNX1 loss of function mutations.

Abstract Abstract 697 Background: Deletions of the long arm of chromosome 5 are frequent abnormalities in MDS and AML. Their size varies considerably. Two commonly deleted regions (CDR) have been described on 5q: a distal CDR deleted in the 5q- syndrome and a proximal region lost in higher-risk MDS and AML. However, the majority of MDS and AML patients with del(5q) show large deletions encompassing both CDRs. Recently, Jerez et al. (JCO 2012) reported on commonly retained regions (CRRs) using SNP arrays and observed that deletions involving the centromeric and telomeric extremes of 5q are asso

Abstract:
Deletions of the long (q) arm of chromosome 5 [del(5q)]occur in patients with myelodysplastic syndromes (MDS) including, but not limited to, those who meet the WHO definition of the 5q− syndrome. Del(5q) MDS patients frequently have symptomatic anemia, and its treatment has traditionally consisted of RBC transfusions and, for some, iron chelation therapy. Erythropoietin, darbepoetin, hypomethylating agents, and lenalidomide can enhance erythropoiesis in MDS patients with anemia, increasing hemoglobin levels and abrogating RBC transfusion requirements. Lenalidomide is particularly active in tre

Background: Deletions (del) 5q in MDS typically occur either in MDS with low blasts and del(5q) (MDS-5q according to WHO) or in MDS with complex karyotype (CK). While MDS-5q are generally associated with a favorable prognosis and harbor TP53 alterations (alt) in 10-20% of these cases (most commonly single-hit), MDS with CK are associated with an unfavorable outcome, harbor additional cytogenetic abnormalities such as monosomy 7 or del(7q) and del(17p) and frequently show TP53 alt which are multi-hit in 80-90% of cases.

Abstract Abstract 612 Background: Chromosome 5q deletion (del5q) is the most common cytogenetic abnormality in myelodysplastic syndrome (MDS). Although haplodeficiency of several genes may contribute to the disease phenotype, allelic deletion of the ribosomal protein S14 (RPS14) gene is a key effector of the hypoplastic anemia. Disruption of ribosome assembly arising from RPS14 deletion leads to nucleolar stress that triggers p53 activation. In a murine model of the human 5q- syndrome, TP53 inactivation was alone sufficient to rescue the hematologic phenotype, indicating that the molecular pat

Abstract Background: MDS with del 5q are characterized by profound anemia, which until the recent introduction of lenalidomide (N Engl J Med2005; 352: 549–57, J Clin Oncol2005;16S:5), was considered generally unresponsive to available treatments. In order to reevaluate the outcome of those patients in the pre-lenalidomide era, we analyzed response of anemia in MDS with del 5q treated with EPO ± G-CSF and thalidomide in previous GFM trials.

Myelodysplastic syndromes (MDS) include a heterogeneous group of disease characterized by dysplasia of one or more bone marrow cell lineages, usually with prominent ineffective erythropoiesis and genomic instability leading to anaemia and enhanced risk to transformation to secondary acute myeloid leukemia (AML) . Thus MDS is often diagnosed on the basis of chronic macrocytic anaemia accompanied or not by leukocytopenia and/or thrombocytopenia.

Conventional karyotype has a crucial role in myelodysplastic syndrome (MDS) and is one of items of the International Prognostic Scoring System (IPSS) for patient risk stratification and treatment selection.

Chromosome 5 presents an extensive collection of genes, and includes several cancer-associated ones. The contribution of chromosome 5 in abnormalities is evident through somatic translocations, germline, somatic, and, in some instances, expression of genes. Various syndromes are associated with chromosome 5, such as 5q minus syndrome, leading to the development of acute myeloid leukemia, PDGFRBassociated chronic eosinophilic leukemia contributing to acute myeloid leukemia, and myelodysplastic syndromes.
