Recurrence of hepatocellular carcinoma in the liver remnant after hepatic resection.
We analyzed the results of 19 patients who had intrahepatic recurrence of hepatocellular carcinoma (HCC) among 47 patients who were discharged from the hospital after having a hepatic resection in order to evaluate the factors affecting recurrence and survival. Recurrence-free survival rates were 80%, 44%, and 28% at 1, 3, and 5 years, respectively. Of the 19 patients with recurrence, 14 had multiple lesions, and 16 of the recurrences were detected within 3 years of surgery. None of the following factors correlated with recurrence: hepatic function; tumor size; presence of tumor capsule; capsular invasion; vascular invasion and intrahepatic metastasis; extent of hepatic resection; and resection with tumor-free margins. Patients having multiple recurrent HCCs, however, had larger-sized tumors at the time of resection than those with a solitary recurrence. The survival rates after recurrence were significantly better in patients with a solitary recurrence, and these patients were treated with transcatheter arterial embolization (TAE) therapy. Early detection as well as TAE for recurrent HCCs is necessary to improve long-term survival.
