Figure 1From: Gene expression profiles derived from fine needle aspiration correlate with response to systemic chemotherapy in breast cancerFNAs are representative of the entire tumor. (a)Dendrogram representing similarities in the gene expression profiles between different FNAs and surgical specimens. FNA-surgical specimen and FNA-FNA pairs from the same patient clustered together more than with samples from any other patient. *Surgical specimen. (b)Representative scatter plots indicating levels of similarity between the cDNA microarray results comparing different specimens. (panels a and b) Comparison of log expression ratios derived from two pretreatment FNAs from the same patient. (panels c and d) Comparison of log expression ratios derived from surgical specimens and the corresponding FNAs from two different patients. (panels e and f) Comparison of log expression ratios derived from two pretreatment FNAs and from a pretreatment FNA and a surgical specimen from different patients, respectively. The correlation coefficient of each comparison is shown at the top left of each panel.Back to article page
