Reports on the protein expression analysis of GGT7 are only limited to ovarian cancer and glioblastoma and have produced conflicting results; in the former, strong GGT7 expression was associated with higher serum GGT, which was in turn associated with an advanced tumor stage and a worse prognosis while, in the latter, strong GGT7 expression was associated with a better prognosis [23,24]. The gene discussed is GGT7; the disease is neoplasm.
