For the univariate analysis of OS, in the training cohort, the relative level of RAP80 mRNA expression (**p = 0.001), tumor size (*p = 0.025), lymphatic invasion (*p = 0.024), lymph nodes metastasis (*p = 0.011), and tumor stage (**p = 0.006) were prognostic indicators (Table 2). The gene discussed is UIMC1; the disease is neoplasm.
