RPP30 and neoplasm: Univariate analysis also revealed that T stage (p = 0.011), N stage (p = 0.002), M stage (p = 0.004), pathological stage (p < 0.001), primary therapy outcome (p < 0.001), residual tumor (p < 0.001), age (p = 0.005), and RPP30 expression (p = 0.012) were significantly correlated with OS.
