Moreover, univariate analysis in gastric cancer tissues showed that tumor grade (P = 0.020), infiltration depth (P = 0.011), lymph node invasion (P = 0.011), TNM stage (P = 0.031), PFTK1 expression (P = 0.002), and Ki-67 expression (P = 0.013) were prognostic factors of overall survival (Table 2). This evidence concerns the gene CDK14 and gastric cancer.
