Previously, chromosomal imbalances [7], [14] and high frequencies of CNV [10], [11], [12] on chromosomes 3, 5, 7 and 14, as well as epigenetic (methylated DNA) aberrations of HOXA5, HOXA7 and HOXA9 at 7p15.2, were associated with early clinical stage [17] and clinical progression [24] in NSCLC patients [17], [24] and NSCLC cell lines [14], [17].
