Introduction: Colorectal cancer (CRC) is the second-leading cause of cancer-related deaths worldwide. Distant metastases are usually located in the liver and are present in 50% of patients. Aim: The aim of this study is to evaluate changes in body composition and phase angle before and after surgical treatment of CRC liver metastases, as well as survival time and treatment costs. Material and methods: The study included 134 patients who received 174 surgeries for CRC liver metastases. Bioelectrical impedance analysis (BIA) was performed using an AKERN BIA 101 analyzer. Results: BIA was performed before and after surgery. The results of tests (total body water content [TBW], body cell mass [BCM], and phase angle) showed a reduction in BCM by 2.21 kg and a statistically significant decrease in phase angle values after surgery (from 5.06 to 4.25 in women and from 5.34 to 4.76 in men). These values are below the reference range for both sexes. There was a correlation between phase angle values and muscle mass, both before (R = 0.528, p<0001) and after surgery (R = 0.634, p<000.1). Preoperative levels of the tumor marker CEA were elevated in more than half of the patients. The median survival time after resection of liver metastases was 37.6 months. Discussion: A significant factor that increases complications, mortality, and treatment costs of cancer patients is malnutrition, which could be the earliest symptom of malignant disease. Conclusions: Successful treatment of CRC requires the patients to participate in follow-up examinations and to be aware of early signs associated with recurrence (e.g., blood in the stool or weight loss). The patients’ nutritional status should be monitored and recorded in a DILO card.
