As shown in Fig. 1C and Supplementary Table 1, statistical analysis represents a strong correlation between LSD1 expression and tumor differentiation (P = 0.0093), tumor size (P = 0.0023), lymph node status (P = 0.0015), distant metastases (P = 0.0070), Nevin's stage (P = 0.0032) and TNM stage (P = 0.0183). The gene discussed is KDM1A; the disease is neoplasm.
