In univariate analysis, significant factors closely associated with OS included BMI (p = 0.010), serum albumin (p < 0.001), CEA levels (p < 0.001), number of liver metastases (p < 0.001), maximum diameter of the liver metastases (p < 0.001), adjuvant chemotherapy (p < 0.001), and sarcopenia status (p = 0.129) (Table 3). Here, ALB is linked to sarcopenia.
