BackgroundThe indications for preoperative hepatic transarterial chemoembolization (TACE) have not been clarified by recent studies in patients with hepatocellular carcinoma (HCC) complicated by chronic liver diseases. The aim of the present study was to investigate which patients benefit most from preoperative TACE on the basis of hepatic functional reserve. Technetium-99m diethylenetriamine pentaacetic acid-galactosyl human serum albumin (Tc-GSA) liver scintigraphy was used to assess hepatic functional reserve before and after TACE.Patients And MethodsLiver scintigraphy was performed before and several weeks after TACE in 64 patients with HCC complicated by chronic hepatitis or cirrhosis. The ratio of liver to heart-plus-liver radioactivity of Tc-GSA 15 minutes after injection (LHL15) was calculated. Conventional hepatic functional tests were also performed. Whether to perform hepatectomy after TACE was decided mainly on the basis of the previously reported value of LHL15 > or =0.91.ResultsLHL15, prothrombin time, and serum concentration of cholinesterase significantly decreased after TACE in patients with LHL15 > or =20.91 (P <0.01, P <0.05, and P <0.05, respectively). In patients with LHL15 <0.91, LHL15 and functional liver volume significantly increased after TACE (both P <0.05). Eight patients with LHL15 > or =0.91 did not undergo hepatectomy because LHL15 decreased to less than 0.91 after TACE, whereas 7 patients with LHL15 <0.91 underwent hepatectomy because LHL15 increased to more than 0.91 after TACE. Three major postoperative complications occurred in patients with LHL15 > or =0.91, and no major complications occurred in patients with LHL15 <0.91.ConclusionsThe results suggest that preoperative TACE should be performed in HCC patients only when LHL15 is less than 0.91, and that preoperative TACE is not an appropriate treatment for patients with LHL15 > or =0.91 when HCC is resectable.
