Comprehensive analysis of the chromosomal rearrangements in these complex karyotypes has been hampered by the limitations of conventional cytogenetics. As a result, our knowledge concerning the cytogenetics of these malignancies is sparse. Here we describe a multiplex\u2010FISH (M\u2010FISH) study of CCAs in 36 patients with AML and MDS. M\u2010FISH generated a genome\u2010wide analysis of chromosomal aberrations in CCAs, establishing several cytogenetic subgroups. \u20105\/5q\u2010 was demonstrated in the majority of patients (86%). Other rearrangements (present with or without \u20105\/5q\u2010) included: deletion of 7q (47%), 3q rearrangements (19%), and <jats:italic>MLL<\/jats:italic> copy gain or amplification (17%). These genetic subgroups seem to display biological heterogeneity: <jats:italic>MLL<\/jats:italic> copy gain or amplification in association with 5q\u2010 was detected only in AML patients and was significantly associated with extremely short survival (median overall survival: 30 days, <jats:italic>P<\/jats:italic> = 0.0102). A partially cryptic t(4;5)(q31;q31), a balanced t(1;8)(p31;q22), and an unbalanced der(7)t(7;14)(q21;q13) were detected as possible new recurrent rearrangements in association with CCAs. Novel reciprocal translocations included t(5;11)(q33;p15)del(5)(q13q31) and t(3;6)(q26;q25). We conclude that AML and MDS with CCAs can be subdivided into molecular cytogenetic subclasses, which could reflect different clinical behavior and prognosis, and that three recurrent chromosomal aberrations are associated with karyotype complexity. \u00a9 2002 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/gcc.1212","type":"journal-article","created":{"date-parts":[[2002,9,9]],"date-time":"2002-09-09T19:37:26Z","timestamp":1031600246000},"page":"60-72","source":"Crossref","is-referenced-by-count":86,"title":["Identification of cytogenetic subclasses and recurring chromosomal aberrations in AML and MDS with complex karyotypes using m\u2010FISH"],"prefix":"10.1002","volume":"33","author":[{"given":"Heidi","family":"Van Limbergen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce","family":"Poppe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucienne","family":"Michaux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Herens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jill","family":"Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc","family":"Noens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zwi","family":"Berneman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robrecht","family":"De Bock","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"De Paepe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Speleman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2001,12,6]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/25.17.3389"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1101\/gr.6.5.404"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2141.1982.tb02771.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-103-4-620"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-4608(96)00096-9"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0888-7543(91)90025-A"},{"key":"e_1_2_6_8_1","first-page":"127","article-title":"Cytogenetics of myelodysplastic syndromes","volume":"33","author":"Fenaux P","year":"1996","journal-title":"Semin Hematol"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V92.7.2322"},{"key":"e_1_2_6_10_1","unstructured":"HuretJ\u2010L L\u00e9onardC SavageJ.2001.
