N2 - Squamous cell carcinoma (SqC) and adenocarcinoma (AdC) are the two most common subtypes of non-small cell lung cancer (NSCLC). Cumulative information suggests that the SqC and AdC subtypes progress through different carcinogenic pathways, but the genetic aberrations promoting such differences remain unclear. Here we have assessed the overall genomic imbalances and structural abnormalities in SqC and AdC. By parallel analyses with comparative genomic hybridisation (CGH) on tumorous lung tissues and spectral karyotyping (SKY) on short-term cultured primary tumours, genome-wide characterisation was carried out on 69 NSCLC (35 SqC, 34 AdC). Molecular cytogenetic characterisation indicated common and distinct genetic changes in SqC and AdC. Common events of +1q21-q24, +5p15-p14, and +8q22-q24.1, and -17p13-p12 were found in both groups, although hierarchical clustering simulation on CGH findings depicted +2p13-p11.2, +3q25-q29, +9q13-q34, +12p, +12q12-q15 and +17q21, and -8p in preferential association with SqC pathogenesis (P
