Background
Transarterial-chemo-embolization (TACE) is used for palliation of unresectable hepatocellular carcinoma (HCC). We studied the tolerability of TACE in a cohort of patients with NASH and alcoholic cirrhosis related HCC.
Methods
Of 290 patients with HCC (July 2011 - December 2014), 84 underwent TACE. They were monitored for post-TACE complications: postembolization fever (PEF), nausea and vomiting (NV), abdominal pain, infection, acute hepatic decompensation (AHD) and acute kidney injury (AKI).
Results
84 patients [90.5 % males, 89.2 % cirrhotics, 89.2 % nodular HCC, median age 63 (34–84) years] underwent 111 TACE sessions. All were Child class A [69.4 % sessions (n = 77)] or B; ascites and portal vein invasion was present in 18 (16.2 %) and 15 (13.6 %), respectively.
42 (38.2 %) TACE procedures resulted in complications [PEF 28 (25.2 %), NV 4 (3.6 %), abdominal pain 9 (8.1 %), infection 7 (6.3 %), AHD 13 (11.7 %), AKI 3 (2.7 %)]. There were no immediate post-TACE deaths.
On univariate analysis elevated serum bilirubin (p = 0.046) and low serum albumin (p = 0.035) predicted PEF while low serum albumin (p = 0.021) and low platelet counts (p = 0.041) predicted AHD. In the multivariate model, factors with p < 0.200 on univariate analysis and factors derived from the previous literature were considered covariates. Female gender (p = 0.029, OR = 1.412), ascites (p = 0.030, OR = 1.212), elevated serum bilirubin (p = 0.007, OR = 4.357) and large tumour size (p = 0.036, OR = 3.603) were independent risk factors for PEF. Tumour diameter >5 cm (p = 0.049, OR = 2.410) and elevated serum bilirubin (p = 0.036, OR = 1.517) predicted AHD.
Conclusion
In NASH and alcoholic cirrhosis related HCC patients pre-procedure serum bilirubin, ascites, tumour size and female gender predicted PEF post-TACE. Tumours larger 5 cm with elevated bilirubin predicted AHD post-TACE.
