Most specimens displayed very complex karyotypes with multiple numerical and structural changes (median number, 31). Losses of chromosomes 9 (65% of cases) and 13 (71%) were the most frequent numerical changes. Loss of the Y was often observed in tumors from males. Gain of chromosome 7 was also frequent (41%). Chromosome arms 1p, 1, 3p, 3q, 6q, 7q, 8q, 9p, 11q, 17p, and 19q were particularly prone to rearrangement. The chromosome arm most often contributing to losses was 9p (79%). Other arms that were frequently lost included 3p, 6q, 8p, 9q, 13q, 17p, 18q, 19p, 21q, 22q, and the short arm of each acrocentric chromosome. The percentage of cases with loss of 3p was significantly higher in squamous cell carcinomas (94%) than in adenocarcinomas (60%). There was also a statistically significant increase in the proportion of cases with gains of 1q, 7p, and 11q in adenocarcinomas compared to squamous cell carcinomas. Several recurrent isochromosomes and unbalanced exchanges were found. Among these was i(5p), which was observed in nine tumors, eight of which displayed adenomatous features. An i(8q) was identified in six cases, including five adenocarcinomas. Double minutes and\/or homogeneously staining regions were seen in seven specimens. These data indicate that numerous chromosome alterations contribute to the pathogenesis of NSCLC and that, amid this widespread genomic disarray, recurrent abnormalities exist that could have biological and clinical implications.<\/jats:p>","DOI":"10.1002\/gcc.2870110307","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T23:46:03Z","timestamp":1172101563000},"page":"178-194","source":"Crossref","is-referenced-by-count":64,"title":["Cytogenetic
