The univariate analysis showed the tumor located in the sigmoid colon and rectum (P = 0.007), low preoperative albumin (P = 0.011), high preoperative lymphocyte (P = 0.021), high preoperative NLR (P = 0.016), high SMA calcium volumes score (P = 0.001), high IMA calcium volumes score (P = 0.001) and high abdominal aorta calcium volumes score (P = 0.001) were significantly correlated with the occurrence of postoperative AL. This evidence concerns the gene ALB and neoplasm.
