However, no significant associations was observed between PRDX2 expression and tumor location (p = 0.604), serum CEA level (p = 0.629), preoperative bowel obstruction or perforation (p = 0.644), age (p = 0.412), sex (p = 0.833), or tumor size (p = 0.471). Here, PRDX2 is linked to intestinal obstruction.
