Abstract:

Objective To investigate the roles of haptoglobin and ferritin in the prognostic assessment of colon cancer patients with liver metastasis. Methods A total of 101 colon cancer patients with liver metastasis were enrolled. The clinical and laboratory data were collected. Haptoglobin and ferritin levels were determined. The patients were followed-up with an endpoint of all-cause mortality. Receiver operating characteristic(ROC) curve was used to determine the efficiency of each indicator. Kaplan-Meier survival curve analysis was used to assess survival status. Cox proportional hazard model was used to determine the independent risk factors for all-cause mortality in colon cancer patients with liver metastasis. Results The areas under curves(AUC) of haptoglobin and ferritin was 0.77 and 0.83,respectively,which were increased to 0.87 when both indicators were used in combination. The optimal cut-off values of haptoglobin and ferritin were 1.37 g/L and 217.1 μg/L,respectively. C-reactive protein (CRP),carcinoembryonic antigen (CEA) and aspartate aminotransferase (AST)in haptoglobin>1.37 g/L group were higher than those in haptoglobin≤1.37 g/L group(P<0.05),and the other indicators had no statistical significance (P>0.05). Age,CEA,alanine aminotransferase (ALT),AST and total bilirubin (TB) in ferritin>217.1 μg/L group were higher than those in ferritin≤217.1 μg/L group,albumin (Alb) was lower(P<0.05),and the other indicators had no statistical significance (P>0.05). Kaplan-Meier survival curve analysis showed that the median survival in patients with haptoglobin≤1.37 g/L(19 months)was longer than that with haptoglobin >1.37 g/L(10 months,P<0.001). The median survival in those with ferritin ≤217.1 μg/L(21 months)was longer than those with ferritin >217.1 μg/L(10 months,P<0.001). Multivariate Cox regression model showed that the Eastern Cooperative Oncology Group(ECOG) score,CRP,albumin,haptoglobin and ferritin were independent risk factors for all-cause mortality in colon cancer patients with liver metastasis [hazard ratios(HR) were 1.99,2.12,1.38,1.76 and 1.70,95% confidence intervals(CI) were 1.38-10.64,1.20-3.72,1.08-2.03,1.14-3.29 and 1.07-2.94,respectively]. Conclusions Haptoglobin and ferritin are helpful for the prognostic assessment of colon cancer patients with liver metastasis.
