We found that high expression levels of OTUB2 were positively correlated with tumor T stage (P = 0.001), American Joint Committee on Cancer (AJCC) stage (P = 0.006), and differentiation (P = 0.010), while there was no significant correlation between OTUB2 protein level and age, gender, tumor location, tumor N stage, or tumor M stage (P > 0.05) (Table 1). The gene discussed is OTUB2; the disease is neoplasm.
