Purpose of review Molecular profiling has proven to be an invaluable tool in cancer research. Although only in its infancy, microarray technology and gene arrays have led to substantial advances in tumor identification, staging and prediction of response: This review outlines some of the more recent advances in the use of microarrays as a novel means to, advance the standard of care. for patients with gastrointestinal cancers. Recent findings Recent investigations have shown that gene expression profiles can be used to identify stage, and guide therapeutic intervention in many gastrointestinal cancers:-In. cases of unknown primary disease, genetic fingerprints can be used to define the origin of the tumor in the majority of cases. Similarly, gene expression has been shown to allow for more accurate staging of patients with. a variety of tumor, types. Perhaps most exciting is early data-that support the potential for microarray to guide therapeutic intervention by providing specific gene fingerprints which correlate with sensitivity to specific chemotherapy; biologic therapy, or other cancer-treatments. Summary Gene microarrays have become a powerful resource in cancer investigations. Individualized cancer care based on specific gene profiles is on the horizon for patients with gastrointestinal cancers.
