Abstract
OBJECTIVES: To assess the association between low hemoglobin (Hb) level and development of contrast-induced nephropathy (CIN) for hepatocellular carcinoma (HCC) patients after transarterial chemoembolization (TACE). METHODS: A retrospective analysis was performed on 284 patients undergoing 503 consecutive sessions of TACE. Propensity score matching (PSM) analysis was used to reduce the influence of the difference in variables in normal and low hemoglobin groups. Risk factors of CIN were assessed by univariate and multivariate logistic regression analysis. The relation between Hb level and CIN development was analyzed by receiver operating characteristic (ROC) curve. RESULTS: CIN developed in 5.6% patients after TACE. Multivariate logistic regression analysis showed that hypertension, Hb and serum creatinine (Scr) were independent risk factors for the development of post-TACE CIN. Grouped by normal or low Hb, the incidence of CIN was 14.6% (16/110) in the low Hb group and 3.4% (4/116) in the normal Hb group after PSM. Multivariate logistic regression analysis revealed that Hb, lymphocyte count, and neutrophil to lymphocyte ratio (NLR) were independent risk factors for the development of post-TACE CIN. The optimal cut-off point at which the Hb concentration resulted in a high probability of developing CIN was 105.5 g/L in males. CONCLUSIONS: Low Hb is an independent risk factor for post-TACE CIN. Therefore, HCC patients with low Hb levels should be closely monitored before and during TACE.
