CD276 and neoplasm: The univariate analysis revealed that tumor length (p < 0.001), multifocality (p = 0.024), LNM (p < 0.001), and B7-H3 positivity in PTCs (p = 0.004) were significantly related to RFS, and the multivariate analysis demonstrated that these four characteristics were also independent predictors of RFS (Table 2, p < 0.05).
