Coexpression of WAVE2 and Arp2 predicts a poor outcome in patients with invasive breast cancer and is closely associated with aggressive and invasive morphology.32 WAVE2 is a candidate prognostic marker in liver cancer and is correlated with a poor prognosis.33 In these reports, the intensity of WAVE2 staining in breast cancer or liver cancer specimens was scored without reference to normal cells. This evidence concerns the gene WASF2 and liver cancer.
