The feasibility of using fine needle aspiration from primary breast cancers for cDNA microarray analyses.

Abstract

SD is a useful quality index for the clinical application of cDNA microarrays. This "proof of principle" study demonstrates that FNAs from primary breast cancers can be used for microarray analysis, although without amplification, it is feasible in only a small proportion of patients. For this to be clinically useful, validated amplification techniques for FNA samples are probably required.
