Abstract
The significance of regional therapy against the intrahepatic recurrence for hepatocellular carcinoma (HCC) was evaluated. During the past 6 years, 101 patients who had radical operations for HCC (liver cirrhosis, 75%; chronic hepatitis, 22%) were followed. Forty-seven patients (47%) had recurrences; the liver was the site of first recurrence in 43 patients and distant site recurrence in four patients. In the patients where the liver was the recurrent site, 33 patients (77%) received regional therapies for an aggregate total of 60 times. Transcatheter arterial chemoembolization was chosen as the first preferred therapy against recurrence in the liver in 30 of 33 patients (91%). Postrecurrence survival of the patients treated with regional therapy was significantly better than disease-free survival (p < 0.001). Disease-free survival after surgery, postrecurrence survival, and postsurgery survival were compared in the patients treated with regional therapy and untreated patients. Fifty per cent survival after recurrence of the treated patients was 27 months, and that of the untreated patients was 3 months. Postrecurrence survival (p < 0.001) and postsurgery survival (p < 0.01) of the treated patients were significantly better than those of the untreated patients. To obtain successful long-term survival after surgery for the cirrhotic patients with HCC, it is necessary to repeat active regional therapies against the recurrent liver.
