Univariate analysis identified high tumor stage (stage I+II vs III vs IV P<0.001), high serum CA199 level (CA199<300IU/ml vs CA199≥00IU/ml, p = 0.034), no administration of chemotherapy (chemotherapy vs no treatment, p = 0.025), and decreased TUSC3 expression level (p = 0.015) as poor prognostic factors for RFS in this study cohort. The gene discussed is TUSC3; the disease is neoplasm.
