Transcription profiling of human node-negative breast cancer patients to validate a 70-gene prognostic signature on a high-throughput microarray


ABSTRACT: A 70-gene signature has been shown to be a powerful predictor of disease outcome in young breast cancer patients. The microarrays were not designed for high throughput processing. To facilitate the use in a diagnostic setting, the profile was translated into a customized microarray containing a reduced set of 1,900 probes.

<h4>Background</h4>A 70-gene tumor expression profile was established as a powerful predictor of disease outcome in young breast cancer patients. This profile, however, was generated on microarrays containing 25,000 60-mer oligonucleotides that are not designed for processing of many samples on a routine basis.<h4>Results</h4>To facilitate its use in a diagnostic setting, the 70-gene prognosis profile was translated into a customized microarray (MammaPrint) containing a reduced set of 1,900 prob  ...[more]
