RRM1 and neoplasm: Univariate analysis revealed that tumor size (odds ratio [OR] = 19.317, p < 0.001), Ts (OR = 3.054, p = 0.001), GPC3 (OR = 3.864, p < 0.001), P53 (OR = 1.808, p = 0.081), RRM1 (OR = 3.331, p = 0.001), BRCA1 (OR = 3.612, p = 0.001), and ARG (OR = 0.394, p = 0.007) were the risk factors for MVI.
