BACKGROUND: Progression of chronic liver dysfunction influenced by long-term chemotherapy or repeated hepatectomy might be related to patient overall survival as well as tumor factors in colorectal liver metastasis (CLM) patients. Our aim of this study was to clarify the relationship between fibrotic liver damage and malignant behaviors of CLM malignancy or its long-term survivals by the retrospective cohort study. METHODS: We examined the relationship between tumor-related factors or six liver fibrosis-associated parameters, including platelet count, hyaluronic acid (HA), mac-2 binding protein glycosylation isomer (M2BPGi), type IV collagen 7S (T4C7), aspartate aminotransferase-to-platelet ratio index (APRI), The fibrosis-4 (Fib-4) index, and clinicopathological parameters, surgical records, and postoperative patient survival in the 45 consecutive patients with CLM who underwent radical hepatectomy. RESULTS: Fibrotic parameters were platelet count of 23.0±8.5 ×10 CONCLUSIONS: Fibrotic markers indicating chemotherapy or repeated surgical liver injury were not significant predictive factors reflecting cancer malignant behaviors or patient overall survival, contrary to our hypothesis. The current overall survival status using various modalities for cancer recurrence is satisfactory under our present perioperative management.
