Numerous genomic tests are available for use in colorectal cancer, with a widely variable evidence base for their effectiveness and cost-effectiveness. In this review, we highlight many of these tests, with a focus on their proposed role, the evidence base to support that role, and the associated costs and risks.

Although genomic testing can improve the cost-effectiveness of a treatment, assessing the cost-effectiveness of genomic testing outside the context of its impact on treatment is not practical.

The identification and characterization of gene signatures, driver events, and pharmacogenomics in molecularly homogeneous subsets of patients is likely to advance effective drug development strategies in colorectal cancer.

The use of tumor genome profiling to identify actionable or targetable mutations in women with breast cancer is not ready for routine use in clinical practice.

This article aims to provide an overview of The Cancer Genome Atlas findings, with a particular focus on their potential biological relevance and therapeutic implications.

TCGA’s efforts to dissect the genomic complexity found in breast cancer patients represents only the beginning of a journey toward better understanding of the intricacy of the events that lead to this disease. Additional efforts are required to provide tailored and effective therapeutic interventions.

The strongest aspect of TCGA is that the data are publically available, fueling the input needed for unparalleled discovery. As the broader scientific community continues to analyze and integrate TCGA data with their own datasets, it is highly likely that breast cancer patients will benefit.
