Abstract
This study was to investigate the safety of transarterial chemoembolization (TACE) which required injection of contrast medium on renal function in combined hepatocellular carcinoma and chronic kidney disease (CKD) patients. A total of 265 patients admitted for the first session of TACE were included for analysis. CKD was defined as Cockcroft-Gault glomerular filtration rate (CG-GFR) < 60 mL/min/1.73 m(2). The odds ratio (OR) and 95% confident interval (CI) were calculated to show the influence of factors on renal function. Overall, 24.07% patients with CKD and 31.21% patients without CKD showed exacerbated renal function at discharge. However, 73.15% patients with CKD and 63.69% patients without CKD showed significantly improved renal function (all p = 0.00001). No significant difference in influence of TACE on renal function between patients with and without CKD (p = 0.20509). Factors to exacerbate the serum creatinine level at the third day after TACE included proteinuria ≥1+ (OR 2.2469, 95% CI = 1.1559-4.3675) and glycated hemoglobin ≥7% (OR 2.0796, 95% CI = 1.0497-4.1200). These factors could be obliterated by admission for more than 3 days after TACE. Serum albumin level <3 g/dL at admission was the only factor to exacerbate renal function at discharge (OR 4.4179, 95% CI = 1.3964-13.9776). In conclusion, TACE exerted same influence on renal function between patients with and without CKD. Most patients showed improved renal function at discharge. Low serum albumin level, proteinuria and poor diabetes mellitus control were factors to exacerbate renal function after TACE.
