There is a high recurrence rate of HCC of up to 50％ or more within three years after hepatectomy. More than 80％ of those recurrences are in the form of intrahepatic metastases. Therefore it is extremely important to administer successful adjuvant therapy to prevent intrahepatic recurrence. There are two types of intrahepatic recurrence : simple dissemination from the primary focus of HCC ; and newly developed HCC in the remnant liver.
TAE is one option for preoperative adjuvant therapy to prevent intrahepatic recurrence.
Postoperative adjuvant chemotherapy via the hepatic artery has occasionally been administered, but it is not yet established as an effective adjuvant therapy. However, a report by Muto et al showed that retinoid administration can prevent intrahepatic recurrence of newly developed HCC after hepatectomy.
On the other hand, adjuvant therapy must not be tooaggressive, because : 1) HCC develops mainly in cirrhotic liver (with poor liver function) ; and 2) locoregional therapy for intrahepatic recurrence results in good survival rats even after detection of an established recurrence.
