Figure 1From: Chromosomal aberrations in patients with head and neck squamous cell carcinoma do not vary based on severity of tobacco/alcohol exposureIdeogram showing DNA copy number changes identified by CGH analysis of primary tumors derived from patients with head and neck cancer with (A) and without (B) tobacco/alcohol exposure. Caption: Thin vertical lines on either side of the ideogram indicate losses (left) and gains (right) of the chromosomal region. The chromosomal regions of the high-level amplification are shown by thick lines (right).Back to article page
