Other human tumor types have also been reported to harbor ERBB2 amplification or overexpression, including lung cancers (Pellegrini et al., 2003; Langer et al., 2004), gastric cancers (Tanner et al., 2005; Bang et al., 2010), ovarian cancers (Tuefferd et al., 2007; Vermeij et al., 2008), prostate cancers (Minner et al., 2010), salivary gland tumors (Cornolti et al., 2007), and bladder cancers (Lae et al., 2010). Here, ERBB2 is linked to lung cancer.
