#65 Deletions of 11q21-q25 are associated with atypical lung carcinoids and a poor clinical outcome

Introduction: Lung carcinoids comprise a group of smoking-unrelated neuroendocrine tumors, which can be classified in typical (TC) and atypical (AC) carcinoids. Classification is complex and its accuracy to predict disease outcome is variable. In a previous array comparative genomic hybridization (arrayCGH) study, we showed that the average number of chromosomal alterations (≥ 1Mb) was significantly higher in ACs than in TCs (512 v. 226 per tumor) and that the most common region of chromosome loss was 11q21-q25 (Neuroendocrinology 2009;90:136-137).
