The results demonstrated that overexpression of P4HA1 was prominently correlated with poor prognostic factors involving more advanced stage (stage I vs. II/III/IV, P = 0.009) and greater primary tumor size (T1 vs. T2/T3/T4, P < 0.001) and weakly related to metastasis status (M0 vs. M1, P = 0.066) (Table 1). The gene discussed is P4HA1; the disease is neoplasm.
