The February Issue of PLOS Medicine includes two studies that relate intratumoral heterogeneity to clinical cancer outcomes. James Rocco and colleagues analyzed data from The Cancer Genome Atlas (TCGA) to show that tumor heterogeneity can serve as a prognostic indicator in head and neck squamous cell carcinoma (HNSCC), and James Brenton and colleagues found higher levels of tumor heterogeneity to be associated with decreased survival in serous ovarian cancer.

In a Guest Editorial, Andrew Beck of Harvard Medical School discusses how these two studies support the idea that molecular characterization of large sets of cancer samples can lead to improved personalized therapies for cancer.
