MTDH and cancer: Interestingly, we identified that MTDH was not statistically associated with RFS in ovarian cancer (P = 0.59); however, the high expression of MTDH was associated with a poor prognosis in other three cancer types – breast (P = 3.5e-10), lung (P = 2.1e-06) and gastric (P = 3.5e-10; Sup Fig. 1).
