There were only positive significant correlations in the ovarian cancer total group: between the HE4 and CA125 concentrations (R = 0.39; p < 0.001), between the CA125 and MMP-7 concentrations (R = 0.27; p = 0.007,) between the CA125 and TIMP-1 concentrations (R = 0.30; p = 0.002), between the HE4 and MMP-7 concentrations (R = 0.35; p < 0.001), and between the HE4 and TIMP-1 or the MMP-7 and TIMP-1 concentrations (R = 0.24; p = 0.014). The gene discussed is MMP7; the disease is ovarian cancer.
