We found that 60.0% patients exhibited high level of PRDX1 and the level of PRDX1 were significantly associated with tumor size (P < 0.001), high malignant grade (P < 0.01), and advanced TNM stage (P < 0.01), but it was not associated with patient gender (P = 0.584), age (P = 0.856), anatomical localization of tumor (P = 0.291) and ALP level (P = 0.880) (Table 1). Here, PRDX1 is linked to neoplasm.
