In a univariate analysis, PFS was significantly associated with gender (HR 0.519, 95% CI [0.311–0.868], P = 0.012), tumor size (HR 2.039, 95% CI [1.210–3.435], P = 0.007), tumor stage (HR 3.255, 95% CI [1.894–5.592], P < 0.001), lymph node metastasis (HR 2.393, 95% CI [1.291–4.435], P = 0.006), differentiation (moderate vs. well, HR 2.321, 95% CI [1.078–4.998], P = 0.031; poor vs. well, HR 3.422, 95% CI [1.601–7.312], P < 0.001), smoking (HR 2.497, 95% CI [1.417–4.402], P = 0.002) and high DJ-1 (HR 5.696, 95% CI [2.933–11.059], P < 0.001). Here, PARK7 is linked to neoplasm.
