However, the analysis revealed that KIF3A expression was significantly correlated with clinical stage (P = 0.047), pathological tumor status (P = 0.045), lymph node status (P = 0.041) and metastasis (P = 0.035) in patients with bladder cancer (Table 1), demonstrating that KIF3A expression levels were positively correlated with clinical pathological stages. This evidence concerns the gene KIF3A and neoplasm.
