ERBB2 and neoplasm: Tumor GGT was significantly associated with sex, lymph node involvement, histological subtypes, tumor nodular formation and Her2 expression (p<0.05 each), and marginally correlated with distant metastasis (p=0.09) and tumor grade (p=0.13); whereas sGGT showed marginal correlation with histological subtype (p=0.11) and Her2 expression (p=0.12).
